Lean red meat, tofu and kidney beans are several good iron sources. Don't skip breakfast, even if you're not hungry. Breakfast helps you maintain a steady blood sugar and energy level. Limiting sugar to less than 10 percent of your daily calories, caffeine to three servings per day and alcohol to fewer than five drinks a week. Caffeine dehydrates the body and works against your body.
Experts recommend exercising at least three times per week.
Energy expended is energy gained.
