The article is misleading, considering the title only says that eating less will extend someone's life. Every person has to intake a certain basis of calories for it to be considered healthy. The first study linked on the article found that cutting calories for mice causes weight loss and related metabolic changes. The article's title says that eating less, not calories, will increase lifespan, which stretches the truth. The food that is consumed is more important than the calories of that food, such as the nutrients and healthy amounts.
