Glucostatic Approach
The glucostatic approach to dieting hypothesizes that overeating and food cravings are related to a low blood sugar level. Likewise that satiation (having eaten enough, feeling full) is caused by restoration of an appropriate blood sugar level. This theory, proposed by Mayer, was extremely popular in the 1950s but fell out of favor in the 1980s as science discovered that appetite has many inputs beyond blood glucose levels.
