The main reason why a person gets fat is that food consumes more calories than it pays, and eating more calories is often the culprit. In food, oil has the highest calorie, so controlling the intake of oil is the key link to reduce fat.
Eating a lot of fresh vegetables is a very good thing, but using salad dressing is not so healthy. Personally, I eat salt, sweet and sour salad, which is refreshing and healthy. You can also try to remove the high-fat salad dressing.
