> Benefit #2. It helps with calorie restriction
No study cited that proves this. Only cites studies about the benefits of "proof" that caloric restriction helps longevity, but really is just a correlation.
> Benefit #3. It helps you lose weight and body fat
No study cited, follows up with "believe me, it worked on me".
Cites this study: "Alternate day calorie restriction improves clinical findings and reduces markers of oxidative stress and inflammation in overweight adults with moderate asthma."
That's incredibly specific and shouldn't be generalized to the general population.
>Benefit #5. It helps your cells clean and repair themselves
Cites studies made on rats/mice. Although that's a good indicator it might be mirrored in humans, it proves nothing.
> Benefit #7. It regenerates the immune system
Study was made on 3 day fasts, and not intermittent fasting.
It would nice if he pointed out those are potential benefits instead.
