I used to eat within a 12 hour window, but a few months ago I cut this down to a 10/11 hour window based on the advice given by Tim in other podcasts and after reading his book, Spoon Fed. I usually eat my breakfast around 7:00 - 7:30am and eat my main meal by 5:30pm - 6pm. I only drink water in the evenings. I have found that fasting any longer than 14 hours does not suit me as I am perimenopausal and suffer from terrible fatigue, light headedness and dizziness etc. Since reducing my eating window I have noticed that I am sleeping much better, that I actually feel hungry when I eat my breakfast (my stomach is empty) and that my digestive system is functioning much better. I have also found that I no longer feel hungry during the day and that I want to eat less for my dinner as I still feel full. I cannot wait for the results of this study.

Well - this is brilliant! I’m 56, had MS since ‘98 and can just about wall walk. Done all the gut protocols and learnt loads. My main aim was to alleviate fatigue, particularly post eating, which I put down to a ‘sugar’ crash. Time restricted eating using a late 9hr window has really energised me! I had noticed that previously when I didn’t eat - I felt better, but thought I should eat as this was the norm. Can’t wait for the study to start and the Personalised Eating Protocol thing - which I haven’t been called up for yet!

Hi I have started Zoe recommended from my son-in-law, he is a scientist Dr Robert Lucas. I never eat till about 10am for years, then started to each breakfast. Things changed, in weight and how I felt, blotted after meals, and it also increased my appetite. Its taken my years to get back to eating at 10 again, feel slimmer inside, I know thats a funny thing to say but its how I feel. I dont eat anything after 7pm as I cant digest it anyway. I dont have a gallbladder now, taken out years ago. It nice now to be more accountable on the Zoe life change way of eating.

I’ve been doing intermittent fasting for approximately 9-10 years. On a Monday I fast from the last meal on Sunday evening to Monday evenings meal. It can be anywhere between 18 - 22 hours, drinking only water, black coffee or green tea. Tuesday to Friday I generally have lunch about 12-13.30 so the fasting period is between 14- 16 hours. Some of those days I may also do a full day fast depending on how I feel. Weekends it depends, sometimes I have a late breakfast, ie brunch but often I don’t eat until lunchtime. I have found this ideal for me, I go to the gym 3 times a week, Monday, Wednesday and Friday and never eat before I gym. I feel my energy levels are higher when not eating than when I eat and it definitely suits my exercise regime. Because I’ve been doing this for sometime my body never feels lacking in anything, and often I have to decide to eat even though I may not be hungry. This lifestyle has definitely worked for me, it gives me more energy and if some days I feel my body needs food when I would normally fast then I would eat, but that’s not too often.

Sounds fantastic! I do IF (for about 3 years so far). I previously I did 16:8 or 18:6 or even OMAD, but now I've settled in to 3 meals a day on a 14:10 schedule. I don't usually fast for 24 hours, but I sometimes think it might be beneficial -- like what you do. It might be impossible to know, but do you feel that there are any specific benefits from your once-a-week 24-hour fast? If so, what benefits do you attribute to that? And this may be difficult to answer, but how do you *know* those benefits are from the 24-hour weekly fast? Sounds like you've got a great routine. Thanks for sharing.

@@karlint39 Thanks for your reply Karl, I started fasting from purely a health benefit side and not to loose weight, although that is also a health benefit. The main aim was to allow my body to function in the way it is meant to, by allowing it to go into what I would say is a self healing phase. When you eat it has to digest and process the food, make new cells etc and fasting as you would know allows the body to repair etc. By going on what I have read, your body needs 12 hours of fasting to start this process and the longer you fast the benefits increase. So for me the one day longer fast is to do just that. I do more days as and when I feel but I’m also aware of weight loss and therefore I’m careful how much I do otherwise I would be fasting longer. Unlike before I started this, not eating has now become easy, I feel it’s a really healthy way to live, gives more energy and together with a good diet which is constantly changing as I learn more from the really informative podcasts like Zoe regarding the microbiome etc it has become a lifestyle I really enjoy. So to answer your question, I don’t necessarily feel any different by doing longer fasts, only in the knowledge that it is beneficial to me.

It's really not a big deal, as when I have a doctor's appointment in the afternoon, I end up fasting from early evening the day before until after the doctor's appointment (because I want to be fasted for the blood tests.)

@@karlint39 You’re welcome Karl, I think the most important thing is to do what you are happy with and what you feel is right for you, otherwise you won’t succeed in doing it. Personally I found it was best for me to extend the fasting gradually and now I can do a whole day as and when. What inspired me to do it was a programme I watched on Horizon back in 2012. It was Michael Mosley’s Eat, Fast and Live longer. It totally made sense that we should be doing intermittent fasting. Most people thought I was nuts, even my children I think but here we are 10 years on and now it’s becoming mainstream. Oh yes my children are also fasting now and have completely changed their diet, my son even bought me a book on food and the microbiome. He lost 3 stone, feels so much healthier, all his joint aches he had have now gone …. “thanks for persevering dad” he said …. you can ask for more than that 😊

I started time restricted eating (plus other changes to diet) last year and it has changed my life, literally. Those closest to me are amazed. Energy levels, anxiety, IBS, sleep all improved. I still have problems on and off (I have chronic heath issues) but the difference is incredible. I eat breakfast after 9am and do not eat after 6pm. Although I have a small dry (water) biscuit snack at 11pm & if I wake in the night. No caffeine, no alcohol, no cakes or biscuits. So not sugary or fatty snax. No animal fats (only heath fish). Only unfiltered organic EVOO. No marge or butter. No milk only oat milk. Smoothie for breakfast. Removed foods that obviously affect my IBS. I'm a new person.

Hi, just started, reported for yesterday's eating. I am stoked about this because I was thinking of dieting but this happened and I think this deserves an honest go before subjecting myself to starvation! The main reason for me wanting to lose weight is to help my blood pressure and if I can do some good this way, I am all for it and cam think about restrictions of calories later when I see how I do. Like I said, couldn't have come at a better time for me!

About two years ago I was diagnosed as pre-diabetic & weighed 75kg, BMI 24.49. I have kidney disease from damage which occured during a lung transplant 10 years ago, so I needed to sort this out. I changed my lifestyle & adopted TRE with a window between 13:00-21:00, but combined it with giving up sugar & sweets (3 sugars every cup of tea all my life), and adopted a low Carb diet (less bread, potato, pasta, rice etc.). The weight wasn't realy the issue & it came off slowly, but I'm now 62.2kg with a BMI of 20.3 and my blood sugar was brought back to an acceptable level within about 3 months, so I'm no longer Pre-diabetic. But change like that isn't easy and it did require a lot of self discipline initially. Sticking at it for a couple of weeks allowed my body to adjust though & since then I feel better generally, never lack energy, I'm rarely hungry (unless I skip lunch as well) & I will continue this the rest of my life because it works for me. And it's really easy to maintain because I've changed my lifestyle & don't even need to think about it like you have to with a 'diet'. With my Kidneys I do need to do more now though, and elimate as much 'processed' food & sauces as possible from my diet because my Kidneys do not handle all the crap in processed food well.

My wife and I began with Prof Longo like Fasting Mimicking Diet every grthree months with great results after watching Trust Me I'm a Doctor 6-7 years ago. Last year I found Dr Gundry: read his books: watched his podcasts and gradually moved to 16-8 intermittent eating. I quickly got used to it and rarely feel hungry on it. I east brunch and dinner between 12:30 and 19:00 using Dr Gundry's dietary advice too: So not vegan, just low carb and reduced protein. While fasting I drink black teas and coffee. On golf days I add some MCT to my coffee. I am now statin free and halved my blood pressure medication and expecting to be off it altogether next year.

You are missing that part of the aim is to give your gut microbes time to digest the food, rather than pushing it all through with never ending eating. The theory is that you will get more energy / nourishment from the food so you don't need as much of it. An added benefit should be a wider range of nutrients from the same food, for instance Vitamin K2 from breaking down plant fibre.

My husband and I have been doing IF since the end of 2020, we do early lunch and early supper due to the way our family works. We have plenty energy, feel great and lost about 10kg each. I (female 61 years old) used to often experience low blood sugar, which made my hands shake and I would feel awful, since starting IF I have never experienced it again. I do power walking for an hour about 4 x a week, do cold water swimming all year for 20 minutes at a time in the ocean in Blouberg, Cape Town and attend callanetics classes for an hour twice a week. I have plenty of energy and feel so much better. I almost completely cut out sugar and wheat because they are not great for my body. I could highly recommend this lifestyle.

I have been doing IF for over 10 years. I have no problem doing 16 hours every day, I feel more alert, full of energy. Sometimes I stray into 18/20 hrs because super busy. I drink herbal teas, no milk or sugar, half a lemon sqeezed in big cup of warm water, later in the day vegetable stock cube in cup of hot water for the sodium. I eat in 6 hour window, some days do OMAD one meal a day, eat until I decide it is enough, odd occasion do 36 hours lots of fluids, used to do 5/2 but find other 5 days of eating not as healthy. My best IF is 16 hours fasting 5 days very clean eating, weekends eat whatever I want but I still do the 16 hours beforehand. Good luck!

Two confounding, omitted variables are the amount of exercise done on a particular day and the amount/quality of sleep the preceding night. In addition to walking the dog twice a day, four days a week I run 5 miles, one day I run 10 miles, one day I cycle for two hours, and one day I go to the gym and do cross training and swim. I get hungry after my 10 mile run (which I do fasted) but otherwise rarely feel hunger. I have found that eating breakfast at around 11am and lunch around 4pm works really well for me.

Before I started TRE, I craved carbs at bedtime and could usually be found eating lots of bread and jam near midnight. I also craved carbs as soon as I opened my eyes in the morning - more bread. I started TRE with 16/8, noon to 8 pm, but found it difficult and opened the eating window to 10 hours, which was mostly doable. Over time, I realized that 14/10 had become really easy - I wasn’t craving carbs as much, and was less hungry. I was making sure to get in 3 meals per day, but that began to feel like too much. It was easy then to move to 16/8, and eat less because I was not having cravings, had no desire to binge on carbs, and felt more gentle hunger in the late morning. I’ve been doing it for several months. I didn’t do it for weight loss but my jeans are looser, and I’m definitely WAY less bloated. I’m vegan (ethical not health motivated), so less bloat is a really nice change. When I do have cravings now, I want an orange and a few walnuts - despite being vegan, I’ve never been that person; I’ve always been the half a bag of cookies person. I turned 70 a month ago and my recent bloodwork has a totally normal lipid profile for the first time in decades. Also my pre-pre diabetes numbers have improved over 4 years ago into the safely normal range. Looks like I’m not drifting into MS any longer. And I never feel deprived.

I lost about 4kg (9 lb). I went off the plan over the summer and gained the weight back. I am trying to get back on the plan again. I have done well most of the time, but at times I feel really hungry at bedtime, so I had a small piece of cheese. That only happened a couple of times.

Oops! I missed the window on this one. It would be fascinating to know the results of the study. When will they be available? I fell into IF whilst I was recovering from my first COVID infection in February 2021. I found that I was so fatigued that I often slept until late morning or midday, got up and then ate a small breakfast. This pattern continued for several months. As my recovery improved, I started actively looking at getting fitter and discovered IF through a KZbin search for fitness tips. It turns out that I was already unconsciously practising TRE by eating during a window from midday until around 7-8pm (eating late gives me horrible acid reflux) each day. I've been practising IF almost everyday day ever since. In the beginning, I was really anti-carbs and lost a lot of weight. I was also very energetic once I fully recovered from COVID. Nowadays, however, I've let carbs back into my life and have noted that some of the weight has piled back on, especially during holidays and Christmas celebrations. Yet, I still prefer to eat from midday onwards until the early evening. It just works for me!

Im just filling out the questionnaire prior to starting the IF study on your app. There are a couple of questions that could really use modification. For example the rate your sleep , there should be an 'average' or 'ok' button to click between 'very good' and 'very bad' , frequency of sleep patterns should also be listed. I had to click very bad because I wouldn't call my sleep patterns always very good , but neither is it always very bad, just occasionally. Another question about your gut habits also started with very medical terminology that is not obvious to all, perhaps that could be simplified.

As far as the difference between men and women vis-à-vis the benefits derived from intermittent fasting are concerned, one thing to consider is that the female hormonal suite tends to encourage carbohydrate craving. This is often a lifelong thing. You don't see this quite as much in men, and I think this explains the dramatically increased levels of obesity in women in the US. Decreasing carbohydrate intake makes intermittent fasting much more tolerable for most people and allows for a significantly shorter eating window. It sounds like Sarah is terrified of having her blood sugars crash, but I can assure you as someone who has done this for years that if you eat a higher fat meal at the end of the eating window, you will not feel "hangry" in the morning.

But in other part of the world women eat carbs on a daily basis without doing IF and they have no problem with obesity. France and Italy ( with bread and pasta), Japan, Vietnam or African countries like Congo and Cameron ( with rice or beans). Carb is not the problem. Eating carbs for a meal does not mean your entire meal is only made with carbs by the way. It's only part of a composed meal which must include other things like veggies....And the type of carbs, processed or not also makes a difference. The main problem in the US is the huge amount of processed food/ empty calories that people eat. The world can see that. It seems that only the US can't. Ulyra rocessed food/drink often has a lot of sugar, no fibers, additives to improve taste, texture, color, shelf life.... Those empty calories "enginered food" push people to eat more often, more sweets, more processed carbs. They are created to make you eat more of it, and more often. The US... run into new miracle diet every 5 years but just want to ignore the obvious. "Things don't need to be complicated when you mainly eat diversed real/ unprocessed food".

@@annettestephens5337 Same here. I wrote a lengthy reply directly to the video earlier, but somehow YT or the Chrome browser screwed up and lost my post just because my internet connection had disconnected. Very sloppy programming. A more condensed version of my story is that I now eat one meal or only within a 4-hour window every day, and never feel hungry or hangry at all. "Not eating" only leads me to thinking that I need to eat to maintain or build muscle; not to end hunger. I was just the opposite years ago; years ago I would over-eat all day and then wake up an hour after going to sleep hungry, and then cook a pound of noodles. I weighed 95 pounds more then than I do now, and I attribute the change in hunger to very infrequent desert-like foods, mostly whole foods, and cycling between lo- and no- carb, which makes time-restriction an effortless breeze.

I think your study with so many people will add a lot of credibility to this research field. I've been doing IF for a couple of years now. BMI 33 down to 22 in one year and then rock steady ever since. HOMA-IR (insulin resistance) of 0.3-0.5 (highly insulin sensitive). I don't think I have more energy, unfortunately. One issue I can see with your 3-week design is that it may take people a while to adjust to a more restrictive feeding window. In the beginning it took self-discipline to not snack in my fasting window, but now, it's easy. I started with not eating 3 hours before bedtime and did two meals a day (18:6 or so) during my rapid weight loss period, and now since I can keep the benefits with less effort, I eat three meals in a 14:10 fasting/feeding schedule. In part, shortening my fasting window was with the intention of improving protein absorption, but that may not be a goal for many people. Certainly an analysis of the first three weeks can be interesting, but ultimately what happens when this becomes the person's lifestyle will be the most interesting. It will also be interesting to look into the social aspects of these new eating patterns. If all of Britain does IF, but half of them eat early in the day and the other half eat late, they won't be able to go to parties together! LOL. Looking forward to hearing the results.

Re the energy, you should do the zoe app if you can afford it, where they test your sugar, fats and gut bacteria(poo). You kind of need to see the full picture and all 3 of those make up the major effecting things. For instance, you may find eating different foods or in a different way may help the energy.

@@paulharris758 Where I am, Zoe is not available, and I guess it won't be in the forseeable future. On the other hand, I have used a CGM and submitted my poo for analysis. The CGM in particular was fascinating. The poo results were also interesting, but the analysis(report) was quite lacking. I don't know what all those species are, and telling me things like "you get constipated easily" or "your gut microbiome is similar to people who find it hard to lose weight." weren't that helpful. In the past those those things applied to me, but now that I've changed my diet, neither is a problem. But yes, I think that both the CGM and poo analysis would be more useful if they were part of an integrated service (like ZOE) rather than stand-alone products/services. Thanks for the feedback!

I just hope the study won’t result in them telling everyone that eating this way doesn’t have any benefits before longer fasting periods are studied as well. I think it would be interesting if they were to study separate groups that have roughly the same amount of people but with different fasting periods per group, say a 1000 people do 10 hours, a 1000 people do 12, a 1000 do 14 and so on. Until recently I didn’t really know much about fasting and didn’t think a longer fast would be safe but after a bit of research I’ve come to believe that it’s generally safe, there’s so much information already. A lot of mainstream health information seems to me to be way behind on this info, sometimes it’s as if “new rules” regarding food, nutrition and diets had been set in stone from around the 1960s & 70s - a lot of it is wrong but its hanging on in there for dear life, it’s set in our psyche.

I've been eating between 11am and 6pm every day for about 6 months now, regardless of whether I exercise in between or not. My goal is to reduce this window further and eventually just eat 1 meal a day with no snacking. However, I'm unsure if going all day would be a good thing because fitting all your daily nutrition in one sitting seems a bit overwhelming, so I'm thinking that perhaps a small bit of fruit in the morning to spread it out a little may be a better strategy. I've read somewhere that it's better to eat fruit on an empty stomach. Also, a little bit of a random thing to mention but interestingly I have an acupressure mat and when I lay on my stomach on it, it tends to bring on hunger and sometimes it even makes my stomach rumble.

The other thing I would say is, as for your rumbles in the tummy, this happens from the day you're born to the day you die, it's just that you only notice it when hungry or empty stomach, and when you've eaten, the rumbles are muffled by the food 🙂 if possible, try reading "ultra processed people" by Chris van Tulleken, it has totally changed how I think about food. Good luck 👍

I do all the other common sense stuff which is correct too - no smoking, drinking, eat whole foods, exercise frequently etc. and my muscles have become much more well defined over the last 12 months.

Hi, as i cant see an answer here, hers my thoughts. Try doing your routine and then change it to something else for the other 7 or more days. Im not part of the zoe team, but I expect if you do a 10 hour window and then reduce it to 6 hours, that would be interesting research wise. If you do 6 hours, then do 10 hours, also interesting, and if you do 8, try 4! Just record it. With 100,000 people, its all going to be interesting and this does attract people who know more about it all and are therefore likely to already be on an intermittent timetable, so try something with a 4 hour difference either way, for the second 7 or more days, if you can and subject to no other answers from zoe themselves. Plus its interesting for yourself too. Or you could try the 7 days with very little carbs to see. And make that the difference. That's my thoughts on it as I'm also already on one. Or try a different time in the day. Re the circadian rhythm, one mans timescale isnt necessarily another's. Just bare that in mind. Good luck!

Non-water weight loss always occurs when less calories are also taken in than put out, but the piggy-bank model of calories is one of the worst *approaches* to weight loss, because it does not reduce hunger. The CICO (calories-in-calories out) is only the final tally on non-water weight change. "A calorie is a calorie" when burning fat, glucose, fructose, or protein in a fire, but in a diet, they and their various combinations and timings affect how strong the drive is to overeat. People do not get obese because they were bad at calorie counting; they got obese because the foods that they ate, and the timing that they ate them in, caused them to be hungrier for more food than they need for their metabolism, which is also affected by what and when they eat. I tried the "move more, eat less" method in 2003 (age 43), after doubling the weight I was when I reached my full height at age 14 (125 pounds to 250 pounds in 29 years). I got down to 187 pounds within a few months, but I was the hungriest I'd ever been in my life, and after all that weight loss, I broke out into binging and eventually got up to about 216 pounds again by 2013 at age 53. At 53, I decided to change WHAT I ate, and started eating more fat, and less processed carbs, getting a higher percentage of my calories over time from meat, eggs, and dairy, and here I am today at age 62 at 156 pounds, with ZERO hunger and my first meal many days at 5PM or later. The chance of me ever getting obese again, without any explicit damage to my hormonal glands, is pretty much nil. I don't have to struggle to resist overeating, as there is absolutely ZERO compulsion to do so.

Hi Ramona! It takes time for the Body to switch from Digestion/Storage Mode to Recycle/Repair Mode after eating a Meal. In your scenario, by the time you're ready to eat Dinner, your Body is just getting ready to switch to Recycle/Repair Mode from eating Breakfast. Eating Dinner puts you back in Digestion/Storage Mode. You're better off extending the good Fasting you've done during Sleep by eating your 1st Meal later OR finishing your last Meal earlier. This gives your Body a longer interval to be in Recycle/Repair Mode.

I Think three quarters of the world, except maybe for Americans, most Europeans, some Asians, already forego at least one full meal a day and most go 12,14, 18 hours without food, and many go a whole day without, not by choice. By choice I eat two meals a day, berries, fruit, nuts, rice, protein, the cheapest I can afford from small markets, private gardens, and in small amounts. Not eating for 12, 14 hours is normal for me. As an American, I am embarrassed by the greed? (eating, munching at all hours)and by the amount of food we waste (throwaways from supermarkets, farms, restaurants, home cooking) without a thought and respect for the food, everyone running after the next fad vegetable, fruit, chemical supplement, etc. Having travelled in countries where often I saw the plight of hunger in children mostly, brought me to the conclusion that the way we look at food in the West is saddening.

As the fluctuations all stay within the most severe option the majority of the time there is no way to show this, if fatigue is something you are interested in there needs to be a much better way to log this as part of the IF study, particularly for those with chronic illness whose normal ranges from say predominantly in bed all day, to mainly housebound to might be able to reheat odd meal here and there and occasionally go for a short walk, to can work part time with rest days provided they rest the rest of the time and have help with other daily living tasks that is a huge range to come under one option of most severe option for fatigue and I don't think you'll see the granularity of data required to see many improvements or worsening

I've been playing with IF with a 10hr window and was hoping tobloose some weight. I have lost around 5lb over approximately 4 months, but my energy hasn't increased, however I have even having skimmed milk in my tea. Is this where I've gone wrong and not lost more weight?

Maybe, as milk will start the digestion process and wake all those daytime bacteria up! Try cutting it out and see. Good for all of us to know. But its more about energy in this short time. Weight is possibly due to carbs. But you could also try an 8 hour window to see.

I follow Stacey sims who specialises in researching diet and exercise in female athletes. Stacey recommends that females should not exercise in fasted state. I love doing IF but at weekends when I want to exercise early in the day I have to make myself have a breakfast. I must admit that I do exercise better when I have eaten.

It’s for people who are already overweight since the sample comes from people enrolled in your paid Zoe program. Biased sample but if it helps that cohort than great. My guess is delaying eating in the morning isn’t helpful but of course cutting off eating after 6pm is very helpful to sleep and glucose metabolism.

Zoe is open to all. This study wants as wide a cohort as possible to look for patterns in response between subgroups as well. Re. Your quote "My guess", that's not what science is about. It's about data and there's not enough solid data on this subject hence this study is required.

it has the potential to improve glucose sensitivity and therefore keep blood glucose within a tighter and lower range which will reduce hba1c overtime. Benefits also cone from metabolic flexibility and fueling the body on exogenous ketones

@@gillsimpson4976 I suspected as much. That's why I wondered. I'm 77 and technically obese but my A1C is still below the threshold for pre diabetes. Bad knees and lungs so I'm not very active which probably accounts for the lack of hunger pangs.

@@reginald2004 I'm 66 Roger and have now stopped taking any pain meds for my joint pain. There is so much anecdotal evidence about the benefits of reducing inflammation in the body and this is better than any weight loss in my opinion. Inflammation is what causes illness and disease. I follow and watch Jason Fung on KZbin. He is a Canadian doctor and so informative on this subject.

I feel that this could trigger a lot of eating disorder behaviours - adding rules around food may not be healthy for some.
@gillsimpson4976

Anyone with an eating disorder should not be fasting. For everyone else we need to look at how so many people are now eating 3 meals a day and numerous snacks. This is not healthy. And the only rule for IF is fast and then feast. Its easy. No stress about counting calories or macros. I feast well so that I can fast well. Its empowering.

Not likely. This idea comes mainly from people who haven't done it. After you get used to it, it isn't a rule. You literally are not hungry outside your eating window, if you become adapted at burning stored fat.

I followed a TRE of approx 8 hrs, I would eat between 10 am (sometimes close to 12 am) and 6 pm, nothing else in the evening , just a coffee in the morning before my work day started. I did that for at least a year with one goal in mind, to lose weight. It was easy for me to do that, I also ate just two meals a day because I had a sizeable meal for the start of my eating window and i would not be hungry until the end of it. However, my goal was not achieved at all, I did not lose almost nothing, barely 2-3 pounds in all that time. I realized that for me, IF is not working for losing weight, I need to change though WHAT I eat (I did not restrict too much my food type, I cook at home, don't eat out or fast foods or packaged foods, is just I like pasta and the bread I bake myself :)); also I want to try to have more than two meals per day (eat often and little). I am working on that right now, difficult to find the right way with all the conflicting information existing out there (do this, don't do it, eat this, don't eat it....sighing).

Hi ....i suppose your problem is the bread and pasta! ...this is really sugar soon after you have eaten it.. This will spike insulin and turn on fat storage for you in you're eating window... Try to reduce or better still remove all the simple carbs ( i just cut out starch which REALLY helped ) ... Its not fun, but you will see a difference I'm sure in weight loss .. Its not easy is it!!! ...but good luck and thanks for sharing your story ... Keith
