This video release is perfect timing for me. As an elderly pre-diabetic women, I have recently found that nothing in excess is a free food. On days that I increase my calories (even increasing my fat) my blood glucose rises on the average throughout the day by 30 points. Getting my calories down while increasing my protein significantly lowers my glucose. For me, it appears 2mad, with no snacks, works to my advantage. I love this channel. Thank you so much.

@@tonny55tonny63 Hi Tonny. I am currently doing 2mad with no snacks. I am trying to reach my protein goal of 140 grams per day divided into two meals. I am keeping my macros at approx. 50% fat, 45% protein and 5% carbs. The only sweetener I use is in my egg white bread, which is allulose. That accounts for my carbs. My breakfast this morning was: 3 eggs, 4 oz chicken breast, 2 pieces homemade protein bread, 1 tab butter. Calories were 633 calories. My dinner will look somewhat the same as breakfast. I am checking my ketones and I am in ketosis and registering between .8-1.8. I test twice a day before meals. I try to eat at 9am and 5pm. I still have 35 lbs to loose. It is a struggle as I am a post menopausal women with a back injury. This week to far I have lost 4.4 lbs. That is amazing for me. I am an extreme case unfortunately. I find having 2 intermittent fasting period (from 5pm-9am and 9am- 5pm) keeps me in ketosis. My hunger is gone. I have been on low carb/ keto for 4 years now. We are all different. I am satisfied with more protein. I wish you success on your journey. Thank you for your interest in mine. 🤗🤗🤗

It's only when I raised my healthy fat intake and lowered my consumption of carbs between 0 - 20 gr per day that, within weeks, I brought my T2D into remission (by March 2017) and manage to lose 30+kilos (by September 2017) . I still measure my BG twice a day. Still perfect. Started LCHF/Keto first week of February 2017, moved on to the Carnivore Lifestyle beginning of February 2018. Fat doesn’t elevate my BG. So maybe I'm an exception to the rule? But then again I never eat after 6 or 7pm.😊

I'm very low carb since 2019 - non diabetic. I recently tried out a CGM which showed me that my BG goes higher for at least the next day if I overeat on my OMAD whether more fat or more protein. Very flat curve in general but eating less overall lowers my BG even when not eating any carbs.

[@tserevenad]

Good work. When you say “high” what numbers?

[@dreamingrightnow1174]

Something I'm curious about (don't have access to a CGM) is, is the increase on days that you may be eating more frequently, as opposed to caloric intake. I read, years ago and haven't fully investigated, that any food coming in triggers an insulin response no matter how small. It seems that insulin insensitivity is a result of too much insulin entering the bloodstream too often. Right now I'm very interested in the framing of excess insulin being more of a overall health issue than glucose levels. It's possible we're naming the problem incorrectly.

[@lf7065]

I understand that you want some glucose rises to trigger insulin. You just don't want spikes. Insulin has important functions in the body in regards to hormone regulation. Having a constant flat line BG level is not desirable.

Hypothesis : Eating huge dose of linoleic acid from sunflower oil leads increased insulin sensitivity of fat cells, leads to increased glucose uptake from bloodstream, leads to reactive glucagon secretion in response to falling blood glucose, liver responds to glucagon with increase in glycogenolysis for quick glucose release and increased gluconeogenesis for subsequently more glucose release. Blood glucose goes high bc external insulin injections are insufficient to suppress glucagon release in pancreas since giving high enough insulin doses to match physiological levels of insulin normally seen by pancreatic alpha cells in non type 1 diabetics would be too high for the rest of body leading to hypoglycemia or even coma. This tracts with the study showing hyperglycemia hours post intervention. In general, hyperglycemia in T1D is due insufficiently opposed glucagon signaling and not from dietary carbohydrates. Repeating the study with cocoa butter (very high in stearic acid leading to transient physiological insulin resistance in the fat cells that are oxidizing it in their mitochondria) may prevent blood glucose fall and subsequent glucagon response. Take home message: Do Not drink a nonfood like sunflower oil before bed whether you have T1D or not.

This is true. Consuming high concentrations of omega 6 fats has shown in studies to increase insulin resistance, hence has nothing to do with eating healthy fats like saturated fats (many people would find this debatable, but studies have also shown saturated fat to have nothing to do with cardiovascular diseases). Throughout history, almost no living being has consumed high amounts of omega 6 fats, as in nature they're only found in nuts. Our fat cells are not adapted to taking in this omega 3-6 ratio.

There is another dimension to this, Time Restricted Eating or Intermittent Fssting. As Dr Fung has pointed out repeatedly, insulin spikes don't make you insulin resistant, continuous insulin spikes do. How does one reverse insulin resistance, let your body recover from a meal induced insulin spike. Remember what the insulin spike actually does. It triggers the cells to uptake glucose. No blood glucose, no insulin spike, no insulin spike, no insulin resistance. This in T2D.

Always told that black coffee doesn’t raise blood glucose, but when I drink black coffee my blood sugar rises 25-30 points. That’s not insignificant. Moreover it stays elevated for several hours.

I believe this statement to be completely untrue. What Ben said is that there is no rise in blood sugar when eating protein (for non diabetics) because the rise in insulin is offset by the equivalent rise in glucagon. In type 2 diabetics there is a rise in blood sugar from protein because insulin resistance of the pancreatic alpha cells keep releasing more glucagon and there is more gluconeogenesis than normal.

Bernstein asked whether she ate anything at thie time: she replied "lettuce". When asked how much lettuce, she said a whole head. The resultant stretching of the small intestine causes insulin secretion, and also glucagon secretion in a non diabetic. It seems her sugar went up because of the glucagon. A head of lettuce contains about 10g of carbohydrate, which would have only resulted in a moderate sugar rise - about 45mg/dl.

One thing that has helped (still have a bout now and then) is I was diagnosed with severe sleep apnea. Once they put me on a bpap it stopped happening. I'm very focused on my sleep now. Another weird thing about this, when I was in my 30s and trying to get pregnant they gave me progesterone and for the 18 months I was on that this condition was completely gone. My doctor didn't think it was related, but who knows. It sounds like you're giving yourself plenty of time in your fast before bed, but maybe this is sleep related. I don't think it has anything to do with the protein, you'd probably have the same issue if you were eating carbs. My best guess is it's hormonal.

I wonder if hypercalorific in the context of needed weight gain would also lead to insulin resistance and/or excessively high blood sugar spikes

[@dreamingrightnow1174]

You can gain weight on keto if that's a goal and it shouldn't create insulin resistance, although we don't know completely what leads to insulin resistance it's probably about too much insulin in the blood stream. I wouldn't even think about changing my fat intake based on this study which seems woefully incomplete. People who gain on keto, without meaning to, usually reduce their fat. If I wanted to gain I'd more avocados and ribeyes and bacon. Btw, have you heard of the beef-bacon-butter-eggs diet? Maybe that would be helpful. All this study really shows is, if you're a rat, don't drink seed oil before bed. :)

is it possible that the people that this test was done on were not LCHF practitoners hence not keto adapted? so their bodies immediately converted the access fats into glucose?

[@loganwolv3393]

Why does the body keep going on with gluconeogenesis while burning fat though? Because on a low carb diet you're gonna eat fat with protein or with a few carbs wich trigger some insulin and that will inhibit the gluconeogenesis so in a setting like that fat won't really do much in terms of blood sugar. I'm curious so see a study like this on saturated fats like lard and butter and see what happens then.

Since 10 grams of fat is the same energy as 20 grams of carbs, and the 10 g fat dose only raised blood glucose 5 Mg/dl, that would have been interesting. Guessing that a T1D might see an increase of 80 mg/dl with the carbs but I don't know that.

[@DrAJ_LatinAmerica]

just like the old saying - "Their is no free lunch". Of course too much fat can / will / does raise basal insulin levels in most people, eg: "too" much. Right, "diet but not in a hypercaloric setting" also fits the old saying - Move more eat less and do some resistance training !!! There are many cases I start people out on exercise / movement and just removing junk from the diet before actually worrying about dieting. Once the person is consistently moving (walking, walking a pool, then light body weight movements....and so on), then progress to a higher level of elimination of foods, then progress to a hard strict diet. Many obese an older find it difficult to get the daily movements and hard dieting all at the same time. It took years to get here, now it might take years to get back. One step at a time.

[@janicelloyd3215]

Some Drs. Say that fat blocks cells and sugar can’t get in. What do you think? I have read that a lot, enough to decrease my fat intake. Some Drs say that you have too much blood sugar , but why ?, take meds or insulin. Who’s right.?

[@tedvoise7964]

anything that stimulates saliva release will jack your sugars(comes from sugar stored in your liver),even 0 sugar/carb foods

[@mertonhirsch4734]

FIRST, Even though replacing carbs with fat doesn't generally lower average blood sugar in any category (non-diabetic, pre-diabetic, type II, or type 1 diabetic), it DOES a) lower blood sugar peak, b) lower blood sugar variability. Peak blood sugar and blood sugar variability are much more closely related to cellular glycosylation damage than average blood sugar. In fact, MODI diabetes who have high A1Cs and average blood sugar, but low blood sugar variability and their risk of heart disease is similar to non-diabetics. When T1Ds replace carb calories with fat calories they start to need more insulin to manage a given amount of carbs. For example individuals with an 8:1 insulin to carb ratio on a 150 gram carb diet have been found to get a 20:1 ratio on a 450 carb gram ratio as long as the carbs are replacing fat. This means that tripling carbs may only require a 20-33% increase in TDD, but the low carb group still has much lower variability and peak excursions. SECOND, NONE of this applies to individuals who are on such a low carb/protein diet that they enter "nutritional ketosis, " the point where the body stops meeting brain needs by turning protein into glucose and instead allows the brain to run on ketones. This occurs only at about 5% carbs and 10% protein and about 85% fat. At that point, fat does not raise blood sugar, or raise insulin needs further, because the brain can function on ketones. Experiments have shown that individuals in nutritional ketosis have shown no hypoglycemic symptoms at a blood sugar as low as 20 mg/dl. If someone is conflating LCHF with nutritional ketosis in generalizing blood sugar effects of fat, they need to go back and do another 5 years of reading up. They are totally different. LCHF will raise insulin needs compared to carbs and raise fasting blood sugar, though reduce variability and peak blood sugar, but nutritional ketosis will result in low fasting blood sugar and insulin requirements as well as virtually zero variability and excursions. I am not recommending a nutritional ketosis diet. It lowers metabolism, m-Torr (muscle building) and thyroid function, but it is great for blood sugar, blood sugar variability, and blood sugar excursions. THIRD, reducing fructose and alcohol intake DOES reduce average blood sugar over time because they are the two main substrates that build liver triglycerides. By the way, if someone on a high fat, low carb diet, or a diet that produces full nutritional ketosis takes a carb challenge test of 50 or 75 grams of fast acting glucose, they will have very high blood sugar from the high carb intake, far in excess of someone who eats carbs regularly, because their cells have stopped making enough enzymes to process glucose to use it up. "Carbing up" periodically from nutritional ketosis is horrible because it will produce blood sugars of over 200. It can be done slowly over a 2 week period introducing a few more grams of carbs each day once or twice a year, but someone in nutritional netosis does not rapidly make glucose into glycogen because their muscle cells are loaded with fatty acids for use as fuel.

[@GregariousAntithesis]

Eating excess calories period no matter carb, fat or protein. The problem with fat is it is a pretty easy conversion for the liver to triglycerides and obviously if your body isnt use to using fat for fuel a pretty straight shot to storage. Would be quite an interesting study feeding people nothing but fat for a diet and trying it with saturated fat, mono fat, poly fats and see the different effects metabolically. The body stores fat as triglycerides so for saturated fats to be stored would obviously be more of a conversion for the liver than poly fats which are what triglycerides are made from. Really not surprised about the results of the study but does answer a nagging question, f fat is converted to glucose to be burned. So obviously even to much fat calories can stop ketosis. I figured out there is a perfect balance of fat protein and low glycemic carbs to keep one in a perfect equilibrium of ketosis and glucose to glycogen. I am repeating myself but you need low glycemic carbs to keep glycogen stores maintained instead of relying on the liver to concert protein or fat to glucose. Gluconeogenisis creates a above average fasting blood glucose eating low glycemic carbs with fat and protein keeps glycogen stores full and a normal range of fasting blood glucose in the 80s and keeps you in ketosis. Its just a matter of not over eating the carbs snd finding your perfect balance via testing your blood sugar. Eating fast carbs interferes with maintaining this balance consistently.

Of course carnivores would disagree with you about the vegetables. The protein alone will convert to glucose if need be.

Friends thought i had cancer i got so thin as a vegan. I could not get enough protein. I had good health markers via blood work but i was also in my 20s. The carnivore diet and its variant's i experimented with because i became boarder line diabetic. I used a CGM and blood glucose testing to record my results. I know carnivores are struggling with having a high fasting and basal glucose i saw the issue myself. Im not in this for some political agenda or being right at all costs. I want to find what foods can eat that give me consistent good blood markers specifically blood glucose but also all the others as well. I have always enjoyed eating vegetables and fruits but fact if you have a compromised metabolism you have to change how and what you eat and some vegs and fruit just arent conducive to something you should include in your daily diet.

First, for this entire thing, please leave the paradigm of "blood sugar spikes", of immediate fed state blood sugar response. This is not it. I noticed this early on when I switched to a very low carb / ketogenic diet. I am type 2, and I feel this clearly applies. I was originally expecting that I could eat all the fat I wanted on a keto diet, because there are so many ill-informed "keto gurus" out there shouting nonsense like "eat more fat to lose fat". They are just low intelligence and can't tell the difference between "high fat" in terms of proportion / percentage and "high fat" in terms of absolute amount. But I noticed soon that excess calories had an effect on my fasting and average blood sugar. Period. If you don't have a CGM and you don't have OCD, you won't notice. And since protein is somewhat fixed, carbs are limited to a minimum, fat is the only "lever" that changes caloric intake on a ketogenic diet. I assume that it really means that, while you are insulin resistant, energy positivity worsens blood sugar control. Period. It makes a whole lot of sense if you spend 2 minutes thinking about it: part of the insulin resistance cycle is energy toxicity. At the other end of the spectrum, we know clearly that a very low calorie diet normalizes blood sugar right away regardless of macro content. With a ketogenic diet, however, if properly formulated, the advantage is a dramatic increase in satiety. The point is not whether you need a negative energy balance (you do), but rather that you can achieve it without even paying attention, in most cases. And, as always, the people who taught us how to do this, folks like Dr. Phinney and Dr. Westman, have always said that you shouldn't overeat fat on a ketogenic diet. Virta has a beautiful little graph that explains how you need to limit exogenous fat while you are still above your optimal weight, and Westman says it outright: "don't overeat fat".

Generally speaking, keto is 20g net carbs a day or fewer while 30-50g net carbs is a moderate low carb, and definitely falls under the umbrella of carb restriction as the "standard" guidance is for 45-65% calories come from carbohydrates and if you're eating 2,000 calories a day, that's over 200 to even over 300 g carbs a day!
