Stop kidding yourself. Research suggests that obese adults with diabetes often say they eat less than they actually do—a problem that can make it hard to manage the disease. On average, diabetic adults reported a calorie intake that was nearly one-quarter lower than they would need even for their most basic bodily functions. Many obese people have inherited abnormalities in the complex pathways that help signal them that they are satiated: They lack the cues to stop eating when they're full. It can help to take small portions and/or to eat only half of what's being served to try to work around this problem with satiety signals. Reducing your food intake a little bit every day (100 calories), which can be done without the insatiable hunger that usually sabotages most diets, will help reduce weight gain and promote weight loss.
