Reply to comment by samaxe1000 in These Headphones kept me sane during my 48 hour fasting session. I listened to Ibiza chill music. by samaxe1000

Nothing wrong with a fast here and there but if it is just to lose weight fast the vast majority will be water.

Not true if in ketosis. Ketosis is when your body depletes all GLYCOGEN (sugar carbs) and uses body fat as fuel. For me, I lost some fat cells so far just by breathing.

Your body burns fat and muscle whenever you are in a caloric deficit of any type. The benefit of a fast for quick fat loss is that it is the fastest (outside of extreme endurance exercise) way to burn fat. If you could burn 3500 calories per day (which is probably a bit more than you really do but a nice number because....) it would mean that you burn the equivalent of 1 pound of fat per day (though some of it will be muscle). There is nothing magical about ketosis that can make you burn more fat than the amount of energy you expend in a day.

If humans (who are not suffering from extreme morbid obesity) could lose 10 lbs of fat from fasting for 2 days then our species would have gone extinct long ago.

Also, you don't lose fat cells, you just reduce the amount of fat stored inside of them.

Do you reject the idea that you are also shedding large quantities of water due to glycogen reserves being depleted?

It's true. Burning fat is your bodies reaction to a caloric deficit in the absence of glycogen storages or carbs in general.

When you fast your glycogen gets depleted, 1g of glycogen binds 5g of water so you'll mostly lose water during the early stages of fasting and afterwards ketosis starts and breaks down your muscles and fat.

With a high caloric deficit the body will also start to break down muscles more than fat because it thinks you're running away from the British again and those pescy muscles will only use up more energy in the future so it is more efficient to get rid of them primarily instead of the fat too outlast the british.

​

If you want to lose fat long term it is not a great method, you should strive for a medium to low but constant caloric deficit.

Intermittent fasting can be an alternative for you if you like fasting. In general all that counts for diets is that you have a caloric deficit but not to much to slow down metabolism.

I know we are all unhappy with our bodies sometimes and always look for quick and easy ways to achieve our goals but for losing weight naturally we haven't found one.

Maybe give the intermittent fasting a shot, works great after getting used to it and helped me to lose 15kg in a year after the lockdowns, also helped my godmother to go from big chonker to chubby.

You lose muscle if you're not exercising. I actually was able to gain in the gym during keto.

Second intermittent fasting! I don't do it for weight loss, that's a side benefit, I like it cause my energy levels are consistent throughout the work day. I cheat on Saturday though, love breakfast foods too much, so I'll have breakfast then my normal meal around 6

Be careful not to hit it too hard. Keto diet is still my go to for readjusting my body fat percentage. It works so well once you get past the keto flu. You just gotta balance your calorie intake as well.

Electrolytes with potassium is the secret to the flu. I eat new york strip steaks and salads. 700 calories. Its hard to over calories in keto unless you cheat.
