Unless they are morbidly obese, American women rarely choose liposuction and other ways to lose weight, but mainly rely on diet to lose weight. As early as 1950, the United States introduced the first diet suitable for people to lose weight, the diet of dieters. 1972, robert atkins put forward the concept of losing weight with high fat, high protein and carbohydrate control, commonly known as "meat-eating diet"; 198 1 year, Judy Ma Zeer published the "Diet Method" in Beverly Hills, and proposed a combined diet therapy based on fruits; 1998 apple vinegar diet came out, claiming that apple vinegar can burn body fat. Some of these weight-loss methods have been sought after by people for decades, and some have long been questioned and denied, and the scenery is no longer there. At present, the most popular weight-loss methods in the United States are "Weight Watcher", "South Beach Diet" and "Dr. Phil Diet".

For Americans, the most trustworthy are diet recipes and diet pills, which is why most diet pills come from the United States.
