No matter what you eat, the pace at which you eat will ultimately decide your food intake, and also how likely you are to gain weight. Hormones control your appetite, and these signal your brain whether you need to keep eating or whether you're full. However, for the brain to receive these signals, it might take up to around 20 minutes. Therefore, if you eat slowly, you'd have eaten less by the time your brain decides you're full. Eating slowly will also give you enough time to chew your food properly, which is also believed to influence better weight maintenance. In conclusion, eating slowly and chewing your food more can keep you from eating more than necessary and gaining extra weight.
