Boost Metabolism By Doing The Sardine Challenge

[@Rachelhasacamera]

Just finished my 3 days. I did only sardines in olive oil and sardines in water. No tea, no coffee, plenty of water. I have hashimtos and hypothyroidism and have been unable to make the scale budge for some time. After 3 days of this not only do I feel great and notice a positive change in energy levels but I actually lost 6 pounds! Edit to add: I went on to do 8 days total and lost 11 lbs!

[@davidfw1866temp]

That's awesome. My wife has hypothyroidism, too, and has been struggling lately to continue losing weight.

[@Rachelhasacamera]

@@davidfw1866temp I continued on for another 5 days so 8 days total and lost 11 pounds by the end of it. Of course most of this was water weight, But it gave me the discipline and motivation necessary to make some big changes that really helped me. Now a month after and I’m still 8 lbs down. I think your wife could really benefit from it! Hypothyroidism sucks. 😣

Sardines are delicious. I dont have a microwave, single and live alone. Then my fridge broke so I started thinking of things I could eat without major cooking, fridge storage, etc. And I am hooked. There are so many delicious brands of sardines. I can't stop. I like the ones in olive oil most but will rotate with water ones so I don't overdo on fat. It is very satisfying and I have been doing it for a few months. But when I cut added sugar and other, that was the game changer. 14 pounds melted away in six weeks and I was never hungry. Now I got all these guys chasing me....20 something year olds and I'm 44! Really was just trying to be healthy! I should say I don't only eat sardines. But they are my main course. I also eat nuts, dates, occasionally a small banana and a bit of 100% cacao. And there are other fish that can be rotated like oysters, mackerel, tuna

Having had an eating disorder since my youth (hyperphagia), I learned to get rid of it at 48 years old. First keto since 2021, then 1st modified sardine challenge in August (recipe from the Carnivore Doctor)... Result after 72 hours, ketones at 2.5. Then 17 days of carnivore, then a cheat Thursday last, unfortunately (the flesh is weak). So Friday the 13th, first day of my 2nd sardines challenge but this time, just canned . 2 every day, not capable of more. Yesterday, I surprised myself by liking sardines for dinner. This morning, blood sugar at 3.3 and ketones at 3.5😲🥰 What a surprise! 6 pounds less. Since I always feel fragile when faced with cheating, I am continuing my challenge today for a 4th day. It's boring but so effective. Thank you for sharing this knowledge which allows us to learn and helps us improve our Health.🥰 I hope one day to be able to get rid of this mental obsession with cheating at the slightest stressful event in life (illness of a loved one, death, moving, high stress at a specific time, etc.). I specify that I only added 20 to 25 gr of fresh lemon juice and it's like eating trout with lemon in fact (I took the sardines in water) then added 60 gr of butter to the two cans each day. Water, salt and a one-hour morning hike in the forest. That's it for me.🤗 I had barriers regarding sardines and yesterday I loved them, so going beyond your barriers, your limits is beneficial. Try!!!💪👍❤

What is gki

[@salad_gold_rancher]

@dfig007 GKI is glucose keto index. I use a Keto Mojo blood sampling device and it automatically calculates GKI. It's a standard measure in the Keto community. The formula is: (Glucose in mg/dL ÷ 18) ÷ Ketones in mmol/L = GKI. GKI ranges are: greater than 9, no keto; 6-9, mild keto for weight loss; 3-6, moderate keto for diabetes control; 1-3, deep keto for neurological issues like Parkinson's; 0-1, very unlikely to attain without medical guidance.

Isn't gout an inflammatory condition? By eating only sardines, there's nothing going into the body to provoke an inflammatory response.
