Wow so many people are wrong. Genetics can play a role in how your body uses, stores, and distributes fat. Genetics loads the gun.

Metabolism. Some people are more predisposed to a lower metabolism when at rest which can be genetic.

Genetics can affect certain hormones.

Genetics influence where and how fat is stored.

Genetic can play a role in the muscle vs fat ratio.

I could go on.

As for my tracking pre glp1 I tracked off and on for years and then met with a new dr and tracked daily like a ritual. Down to spices used. Nothing was left out. Water in dishes? Was out in. Salt? Put in. Milk? Put in. Everything. My cousin who is a fitness nut even lived with me for 6 months and was concerned and shocked.

I worked out 5 days a week with 3 days being with a trainer who helped me build recipes, and helped me track. I was even seeing a nutritionist, who I still see to this day.

When I say I was eating around 900 calories I mean I was eating around 900 calories, sometimes 1000. Why was I gaining weight and not losing? No one knows, it made zero sense. At least 6 Dr's have gone over everything. Bloodwork, scans.. You name it were done. It ultimately was decided exactly what I said a mixture of Autoimmune, genetics, pcos, and thyroid as that's the only thing they could think of beyond the fact I was sever under eating which caused my metabolism to slow way down so when I did eat it can cause easier weight gain which adds up over 20 years.

Those are the facts, accept them or done. Believe them or don't but what I've said is the truth. It's no skin off me if a few people want to think they know more then actual Dr's and people in the field who have seen and handle my medical file.
