Here’s my observations from years of stop starting exercise and diet.
exercise drives my appetite. I can’t diet and start a new exercise plan. It doesn’t work.
so, the choice is cut calories and no exercise, or walking/general NEAT. This means I can reduce what I eat and lose weight.
or, start exercising, and eat as well as I can. 3 meals, one snack. No messing with IF, low carb etc, a balanced diet to fuel the exercise. If I cut something out like carbs it will all go to shit as when I exercise I need carbs. Same with IF, I’m fine until I’m “allowed” to eat, then I can easily overeat because I’m so hungry.
accept I will gain weight because my appetite will increase. Eat meals, don’t try to skip or cut down.
then after about 3 months on a new exercise plan everything stabilises. Appetite drops, and I can start reducing portion sizes, upping veg to protein/carb ratio etc, and generally lowering calories. This is when the weight starts to come off.
stick with it. Build new habits, get them established, then tweak one thing at a time. Tweak calories, or leave them alone and increase exercise. Find that balance that suits you and your lifestyle.
