Yes, actually fat, that is, fat, has little to do with weight. The human body is 70% water. You know that oil is insoluble in water, so fat won't take up too much of your weight. But the volume of fat is very large, so having fat will make you look fat. Losing weight means losing fat, but the order of consumption of these calorie substances in the body is sugar (such as glucose), then protein (lean meat, egg yolk), and then fat, so you must adhere to proper diet and exercise to consume fat.
If you want to lose weight, you'd better do some aerobic exercise. Long distance running is the best. Look at the figure of a marathon runner. When you practice to a certain extent, stop and don't be the pole.
I wish you success in losing weight and hope to adopt it.
