How to Eat in Your 20s, 30s, 40s, 50s and 60s
In your 20s: Build good habits—and bone density—by opting for nutrient-rich whole foods instead of refined varieties (an apple instead of apple juice, whole grains instead of white flour).
In your 30s: Rather than cutting out certain foods or reducing calories, eat smaller, more frequent meals that include a balanced mix of carbohydrates, protein, and fat.
In your 40s: To minimize hormone-level changes that may cause weight fluctuations, replace animal protein and fat with vegetarian sources, like nuts, seeds, beans, avocado, and quinoa.
In your 50s: To fight abdominal fat, focus on making exchanges. Skip coffee and diet soda in favor of green tea, or ditch high-sugar sweets and have a portion of dark chocolate instead.
In your 60s: As your body loses lean muscle, your metabolism naturally slows, putting you at risk for weight gain. Choosing high-quality proteins can help maintain muscle and your body's calorie-burning ability.
