Enjoy your food
This reason is just as powerful, in my opinion. It’s hard to enjoy your food if it goes by too quickly. In fact, I think it’s fine to eat sinful foods, if you eat a small amount slowly. Think about it: you want to eat sinful foods (desserts, fried foods, pizza, etc.) because they taste good. But if you eat them fast, what’s the point? If you eat them slowly, you can get the same amount of great taste, but with less going into your stomach. That’s math that works for me. And that argument aside, I think you are just happier by tasting great food and enjoying it fully, by eating slowly. Make your meals a gastronomic pleasure, not a thing you do rushed, between stressful events.
If you eat slower, you’ll chew your food better, which leads to better digestion. Digestion actually starts in the mouth, so the more work you do up there, the less you’ll have to do in your stomach. This can help lead to fewer digestive problems.
Eating slowly, and paying attention to our eating, can be a great form of mindfulness exercise. Be in the moment, rather than rushing through a meal thinking about what you need to do next. When you eat, you should eat. This kind of mindfulness, I believe, will lead to a less stressful life, and long-term happiness. Give it a try.
Portion size control
Slowly eating can make it much easier to eat less without feeling deprived. It takes some time to feel satiety, so give this time to your body. Eating fast lets you eat too much before you are fully aware of it. Slowing the rate of eating can allow the satiety signals to develop before your plate is empty
