Weight loss advice is nearly a religion. You’re going to have a million different people telling you that something absolutely is or isn’t a certain way. They’ll claim science isn’t science, that the body is magical and mystical and you won’t achieve your goals if you don’t do exactly X or y.

The body does some weird things when you start going into starvation mode but it’s not magic.

If you maintain a calorie deficit, eventually you will lose fat. You’ll also lose muscle.

The calculations for how many calories you actually burn doing something are kind of voodoo, they vary wildly per individual.

You create a calorie deficit so that your body will burn the fat. You work out so that your body will put more energy into building the muscle you’ll be losing. The only way you lose weight is through breathing out carbon dioxide. If you sit around sedentary that’s going to take a very long time.

Pick a target for how much weight you want to lose over a month. Pick a calorie deficit that makes sense to you. Weigh yourself every couple of days and calculate a sliding average. Tune the number of calories you’re eating after the first couple weeks to maintain your weight loss target.

You do need to be careful with extremely low calorie diets. You want to be monitored by a doctor and have regular blood tests to make sure stuff isn’t going awry.

If you want to go cheap, use a free intake monitoring app, eat eggs, beans and rice, try to cram some vegetables in there where you can. Don’t go out of your way to avoid fat but don’t guzzle it either. Shy away from processed carbs like bread and noodles. Don’t necessarily go keto, but keep your carbs in check.
