I went through same deal, but to a slightly lesser degree. I don’t eat from 8pm-12pm most days(sometimes I cave between 11-12 due to work schedule). I eat meat, eggs, nuts, vegetables. No carbs Unless I will be burning a lot of calories from exercise or activities. You can easily figure out your base metabolic rate online, and figure out roughly how many calories you burn a day. Eat less than that, you’ll lose weight. Pretty simple.
certain prescriptive diets help people with significant weight loss. But I’m pretty sure “don’t eat carbs” and “eat less calories than you burn” will work for 99% of everyone else.
