How do you take your regular meal? When the food is delicious, do you overeat? One specialist in geriatrics said that eating moderately may be the key to longevity. That means you have to avoid eating more than enough and also avoid fasting. When you are full then stop eating. As they say, eat to live and not live to eat. Food is to make us alive so regardless of the taste of the food, eat moderately all the time.
