He was a bit bigger. 6'2" 240lbs, and sort of a softer build in general. He lost about the same amount of weight and since we ate similarly we kept it off for the most part.

He didn't have the chronic fatigue issues I had. He had all the short benefits of feeling great, losing weight, etc. But as far as other long term benefits, not really.

In fact something I should have mentioned, is that I think it was way easier to do it with someone. We kept tabs every day, and ate a few meals afterwards. We also traded meals so that if I took the time to make a big Keto meal that took a while to make, I would double it, and vice versa. Much easier to go through something like this with someone else to bounce things off of.
