I've lost plenty of weight with intermittent fasting. It totally works. My sleep schedule went crazy, no matter what I did. My ability to focus was completely lost, as if I was constantly overdosing on coffee.

Yes, it works, and maybe it works easy & side-effect free for some, but tbh I'd rather be overweight and die 10 years earlier, than live like that.

Important to hear this.

An important takeaway from all this is that people react very differently to similar regimes, and projecting our own (successful) experience of a regime onto someone else is likely to not represent their experience.

The sustainability of approaches is what we hear most from the Fellas. Most diets work in the short run but aren't sustainable long-term, especially when you're already battling against your metabolism.
