I have a colleague who hardly eats after noon. Dinner is fruit. It has always been fat in summer, and it has not been obvious until autumn. This process has been going on for three months. So everyone's physical quality is different and the effect is different. You are not fat in height and weight, and you are thinner than fat people.
If you walk for half an hour at night, the effect will be better. If you don't eat but don't eat, your consumption will not increase. On the contrary, because you don't eat and have no energy, your basal metabolism slows down, so you consume less, so the difference between total income and total expenditure is not obvious. It's best to eat a small amount of dinner (it's not delicious at all), increase aerobic exercise and stretching, and insist that it will be effective. The key to everything is persistence and longevity.
