If you count eating to the throat as 10 full, then a normal dinner is suitable for eating to 7 full. The so-called 7-point fullness means that the stomach hasn't felt bloated, there is no sense of burden, and the appetite has weakened. I habitually want to eat more, but if I took the food away at that time, I wouldn't feel sorry and I wouldn't feel hungry before going to bed at night.
If you need to lose weight, just eat until you are 5 minutes full. In other words, the hunger has basically disappeared, but there is still an obvious appetite and I want to eat some more. Maybe a little hungry before going to bed. For people who need to lose weight, this level is enough. If you eat any more, I'm afraid you'll eat too much.
