People who undergo metabolic or bariatric surgery lose more weight on average after one year than those who follow a low-calorie diet, with average losses of 30.2% versus 14.6%, even though both groups had similar weight loss at an earlier matched time.
After metabolic or bariatric surgery, people experience a doubling of GLP-1 hormone levels following meals, unlike those who lose the same amount of weight through dieting. This higher hormone level is linked to feeling fuller after eating.
Obese individuals who lose the same amount of weight through bariatric surgery as through a low-calorie diet experience stronger feelings of fullness after meals, eat less in anticipation of future meals, and show higher levels of the hormone GLP-1 after eating, which is linked to increased fullness.
People who lose weight through metabolic or bariatric surgery tend to maintain lower cravings for carbohydrates, high-fat foods, and fast food one year later, while those who lose weight through a low-calorie diet do not maintain the same reduction in cravings.
In obese adults, weight-loss surgery leads to longer-lasting decreases in hunger levels during both fasting and after meals after one year, while hunger returns to previous levels after dieting alone.
