So I know that Dr Fung believes in not calorie restricting (at least that's the only info I've been able to find). He says if you do a smaller eating window every day, you should still get the same calories...
So I've seen that a lot of people lose weight with IF, but I'm wondering if that is done solely through IF or a combination of IF, exercise and calorie restrictions? I'm looking to lose about 45lbs (20kg), and I...

I know one of the reasons IF is done is to restrict calories since you’re eating less meals in a smaller eating window, but I find that I still eat the same amount of calories in the smaller window. Hence,...

What differentiates intermittent fasting from eating disorders like anorexia, orthorexia, and bulimia? I argue that what makes IF different is one's mindset, i.e., our underlying beliefs about why, when, and what to consume (or not) when we are fasting or...

Guys I am going to do IF from tomorrow so I want to ask should I eat my tdee calories or i should restrict my calorie intake?

As everyone knows, when googling about intermittent fasting, you get a lot of ads and a lot of biased opinions so I would really love to know if intermittent fasting really is good for you, and if it slows down...
There is a big debate about this and I haven't found an answer. Most people say that IF only works because you are eating less and restricting your calories. So that made me think, is it really necessary to stick to a...
