Even if you eat in upscale restaurants in the U.S. or most other high-income countries, you normally are served meals with considerably more calories than you need. If you want to maintain a “Normal” BMI (Body Mass Index) you need to eat only a portion of the meal and take the rest home. It is even worse if you either (1) eat in downscale restaurants or (2) eat at fancy restaurants with 10-course “tasting menus. And if you eat enough to weigh 100 pounds or more too much you can expect to die 14 years younger than a person with normal BMI.
