Fasting

Hmm, it's not for me. Anyone can make themselves appear knowledgeable?

There's lots of diets out there that "fast" but it's short term/3/2 or the 16/8.
I often skip breakfast...but eat my lunch at 12 and my main meal at 7. I've never been thin

I think fasting for a week your body will need to gain energy from the protein available as TMTT has posted, as it has used all resources ... that will be your muscle. I don't see it as a healthy way to lose weight?

The guy is a Doctor and other video's he has made make sense and have worked for me.  It's not about dieting as I am reasonably happy with my weight, it's a challenge, and I like a challenge . If I lose a couple of pounds so be it, if not, what the hell, it's another item ticked off my bucket list!
