Supplements can't substitute for a healthy diet, which supplies other potentially beneficial compounds besides vitamins and minerals. Foods also provide the synergy that many nutrients require to be efficiently used in the body. Still, for many people a basic multivitamin/mineral pill can provide some of the nutrients they may fall short on. Certain people may also need supplements of folic acid, vitamin B12, calcium, and vitamin D (see next slide).
A study in the journal Metabolism found that eating half a grapefruit before meals may help reduce visceral fat and lower cholesterol levels. Participants in the 6-week study who ate a Rio Red grapefruit fifteen minutes before each meal saw their waists shrink by up to an inch, and LDL levels drop by 18 points. Though researchers don’t exactly know what makes grapefruit so good at burning fat, they attribute the effects to a combination of phytochemicals and vitamin C found in the tart treat.
With its trifecta of carbs, protein, and fat, Greek yogurt can keep you full and ward off hunger by keeping blood sugar levels steady. Instead of choosing the non-fat kind, go for 2 percent or one with whole milk—selecting non-fat is a surefire way to wind up hungry soon after downing your meal. A single cup of Fage Total 2 Percent has 170 calories, 4.5 grams of fat, and a whopping 23 grams of protein.
Your favorite childhood snack is good for your grown-up self, too. Because peanut butter is a great source of protein and healthy fats, it can curb hunger and keep you feeling full long after you're finished eating. Having small snacks during the day that include a lean protein such as peanut butter with complex carbs (like an apple or banana) can also help keep your metabolism running smoothly.
Want to lose weight? Grab a bottle of V8! According to a study published in Nutrition Journal, tomato juice consumption can aid weight loss because it increases resting energy expenditure (REE)—the amount of energy expended by a person at rest. After eight weeks of drinking unsalted tomato juice twice daily, the 95 women in the study (who were each exhibiting some menopausal symptoms) increased their REE by an average of over 100 calories per day.
Kamut is an ancient grain native to the Middle East that is an excellent source of heart-healthy omega-3 fatty acids, protein, and fiber, while simultaneously being low in calories. In fact, a half-cup serving of the stuff has 30 percent more protein than regular wheat and just 140 calories. What’s more? A study published in the European Journal of Clinical Nutrition found that eating Kamut reduces cholesterol, blood sugar, and cytokines (which cause inflammation throughout the body). Kamut’s ability to stabilize blood sugar and reduce inflammation make it a great weight loss staple, especially if it is used in place of nutritionally lacking refined grains.
