So, it works?

Yep. I've hard it all comes down to calories out minus calories in.

Really anything that comfortably and sustainably controls calories in, for your individual lifestyle and metabolism, is going to work.

For some people, I imagine that could be intermittent fasting.

Personally, I just got out of the habit of eating breakfast, at some point, and I found it helped control my total daily calorie intake. (I don't know if that counts as intermittent fasting?)

The key thing I had to internalize is that my "diet" can not just be something I do for awhile - it has to be my new normal, for any positive change to stick.
