There are visceral sensations in your stomach. It’s thoughts, about food and eating. It’s physical weakness, dizziness, anxiety, headache, irritability, and inability to concentrate. It is also transient changes in blood glucose, increases in plasma grehlin, motilin, and leptin. It’s the amount of time since your last meal, the sight and smell of food, and the extent to which you like this food. It’s a physiological state and a subjective state that differ from individual to individual. This is a behind the scenes look at hunger.
If it’s true that overweight women don’t give themselves the chance to experience their hunger, then it’s a good bet that letting yourself get hungry is a step towards loss of weight.
