Weight loss and perseverance
I have found by talking with people that have dieted to lose a bunch of weigh is that they miss the part about calorie burn changes after losing the weight.
It inevitably causes them to gain most (or all) of it back.
When I was 320 lbs, my calorie burn rate was 3300 calories per day just to stay even. At 200 lbs, my daily calorie burn rate is 2100 calories to stay even.
If you diet to lose the weight and then go back to your old eating habits, that old high calorie diet will just put the weight back on.
You need to adjust your caloric intake to your new weight if you want it to stay that way.
The equation is simple, calories in vs calories out. Eat more than you burn and you gain weight. Burn more than you eat and you lose weight.
There aren’t any strange rules or myths like not eating carbs, keto, counting macros, or other any of the things fad diets proclaim. There are no good foods or bad foods. A well balanced diet for good nutrition and maintaining health is all that is required.
It’s nothing more than a fundamental energy balance. What goes in and what goes out. If either one is greater than the other, the balance tips that way.
It isn’t magic or some kind of mystery nutritional science…it is as simple as it gets.
