For me, Intermittent Fasting just fit my lifestyle. I use the 16:8 method because I'm not hungry when I wake up, I love drinking black coffee and I prefer to have larger meals later in the day instead of small meals spread throughout the entire day. For me, I was able to drop 160 lbs while also packing on a decent amount of muscle mass. I'll probably use IF forever...

Thanks for the video, I've been doing 16:8 fasting for the last year. When I first start I removed all sugar and carbs from my diet and did the warrior diet which was hard but WORKED !!! Couldn't sustain that diet because it was much easier eating the same food my kids were eating then preparing different meals all the time. So I now do 16:8 and it doesn't dramatically help with weight loss, but I feel good.

I don't follow this diet but sometimes I inadvertently do the fasting method of my partner, which is eating only within the 8 hour period and we eat twice at 10am and 6pm. It actually feels pretty good and is much easier than I would have thought.

Islam teaches me many things,  not only fasting in ramadan, sunnah fasting on monday and thursday every week of the month also taught to us.☺

I don’t eat at all on my fasting days. I tried just eating 25%, but it felt like more work. I hate counting calories so I find it easier to not eat on my fasting days.

You are what you eat, you can see it in the mirror, and will feel the interactions.

This is a scientific question? Does eating less food mean you’ll lose weight? Yeah...I’m gonna have to assume it does.

Does the body reach autography during the 5 2 eating Plan?

Fasting is yet another diet "cult fad". Fasting stresses the metobolic system and can cause subtle organ damage which can become chronic and gradudually accellerate. A suuggestion I make to you is "partial" fasting. Just skip a few meals but eat "something" during your "fast" day. I have studied dieting and metabolism for 50 years. I personally have been "partial fasting" for decades and that has kept me what I like to call "trimmed". For your fast day, eat some fruit or an undressed 3 ounce mini salad. Drink plenty of water. "Undressed" means just some raw leafy greens, cucumber, onion, carrot - WITHOUT junk like cheese or egg, etc. Btw, Stop being fooled, cheese is quite unhealthy and should rarely be eaten. If your poop is really smelly, or your pee is strong smelling, you are eating wrong. Your "output" should only smell up close, not stink up the whole bathroom. The stink is caused by too fatty a diet.
