PART III: How Should I Eat? (Not too much.)
Rule #54 - "Breakfast like a king, lunch like a prince, dinner like a pauper."
Eating a big meal late in the day sounds unhealthy, though in fact the science isn't conclusive. Some research suggests that eating close to bedtime elevates triglyceride levels in the blood, a market for heart disease that is also implicated in weight gain. Also, the more physically active you are after a meal, the more of the energy in that meal your muscles will burn before your body stores it as fat. But some researchers believe a calorie is a calorie, no matter what time of day it is consumed. Even if this is true, however, front-loading your eating in the early part of the day will probably result in fewer total calories consumed, since people are generally less hungry in the morning. A related adage: "After lunch, sleep awhile; after dinner, walk a mile."
Eat food. Not too much. Mostly plants.
