Hi, so I heard doctor fung talk about how fasting for periods of 3-4 days won’t slow your metabolism. He showed a chart of someone’s metabolism when on a traditional low calorie diet wich included carbs compared to someone fasting....

So I was on TikTok and I came across some videos saying that if you eat low calories (1000 or 500) a day your metabolism will slow down and you won't lose weight. Because your body has gotten use to...
Hey! So I have. Some questions about low calorie/fasting So I just finished a 36 hour fast, I broke it with an avacado and sardines. In the days after I have been eating OMAD( Keto) , or two small meals within a...

I went from 255 to 140 with keto and IF (usually OMAD with occasional 48h and 72h fasts in between). I'm now maintaining with low-carb and 16:8 IF. That means I skip breakfast and I don't ever snack even in...

So I’ve always had a hard time losing weight. I can literally workout every day, and eat like salmon and spinach and barely anything else in a day. I just won’t budge one lb. However I’ve recently discovered with fasting,...
I'm interested in ways to trigger fat burning and/or how to increase metabolism.
I am on day 17/30 and haven't seen much weight loss over the last week. I wonder if this is because the body has adapted to have a lower metabolism, and thus the basal calories burnt are v low. https://preview.redd.it/qtkoadg000oa1.png?width=1280&format=png&auto=webp&v=enabled&s=0946d2369e604531326ca1bd4c64cc8902f7570b https://preview.redd.it/opx1xfg000oa1.png?width=1292&format=png&auto=webp&v=enabled&s=892e6e4643973e9861ccccb693e823fdcb7f84a2

I never had success with “calories in / calories out” dieting. I’d lose a few pounds after weeks of limiting calories and gain it back just eating normal meals. What was successful was fasting roughly 36- 50 hours...
If I keep my calories at a 500 deficit and also add intermittent fasting or weekend longer fasts in, does that lower the metabolism? Edit: For context I’m 26F 5’5 and 157lbs wanting to get down to 140/130

I suppose this should be phrased as "why is 1200 calories considered a minimum, regardless of activity, gender, height and weight". I understand that this would be a substantially low number for a tall active male, however when you start dropping...
When you exceed a certain number of hours of fasting, around 20 hours, your body starts producing something called Reverse T3, which is used to reduce metabolism. To understand what reverse T3 is, we need to know what metabolism is...
Assuming a sedentary lifestyle, would it seem to be much more difficult to fast (esp longer fasts) on a high carb diet? Because of insulin spikes and drops?
Ive been doing weekly 72hr fasts for a few weeks in conjunction with a low carb-whole food diet and I’m absolutely loving it and am getting closer to my weight loss/fitness goals. I’m interested in trying a longer fast (7 days...
