Fatass here, early 30s, bodyfat% somewhere between 25-30%. I'm trying to lose 45+ lbs to mostly get rid of my belly and look like a regular non-disgusting human being. Looking for some advice/feedback on my diet and possibly also recommended/sensible supplements.

I've decided to do low carb OMAD, meaning I just eat once per day (dinner), mostly meat/fish with a bit of dairy (cheese, greek yoghurt) and green veggies. Trying to always get at least 100g of protein in, if necessary by adding one or two whey shakes, and also adding some fat (butter) to get the calories to at least over 1000. Typically I should be somewhere in the 1k-1.5k kcal range daily, so a pretty big deficit for my fatass basal metabolic rate. Three weeks in right now, lost around 17 lbs so far, no idea how much of that is/was water weight, feeling pretty good and OMAD feels easy to maintain.

In terms of supplements, I only take three: A) a multivitamin to hopefully compensate for any minerals/vitamins I'm missing with my very reduced nutrition, B) fish oil for omega3, and C) a collagen/HA supplement to hopefully help a little bit with loose skin on the belly, which I will presumably have if and when I'm successful in my goals.

Feedback and thoughts are appreciated
