I think this is the main problem for people being overweight. Always finishing your meal is a terrible habit. Listen to your body instead. A served meal will never match with how many calories your body needs. Most people especially Americans are terribly overeating due to the large portion sizes. Humans were never meant to stuff themselves to the max every meal especially once we transitioned to 3 meals a day compared to comparatively fewer when hunting and gathering. Stop eating when you no longer feel hungry anymore or feel decently full. anything past that is a negative.
Either pack the food for later or even throw it out. Overeating is a waste of food regardless since you’re just converting it to fat. It’s worse than throwing it out. You might think if you overeat one meal you’ll save on food in the next, but usually digestion speeds up the more u eat and you’re on track to eat the same amount anyways. #entertainment
