Before making a purchase, think about why you are eating that bar—for additional protein, as a nourishing snack or as a convenient meal replacement? Do you feel that because you are dieting, exercising or focusing on your health, that energy bars are simply a must? Whatever your reasoning, know that energy bars are not a necessary part of a healthy, balanced diet. Before you buy, remember these pros and cons:
Pros
There are many reasons why energy bars are so popular. In general, energy bars:
- Can help meet your energy (calorie) needs.
- May help meet your nutritional needs for protein, carbohydrates and fat.
- May help to meet other nutritional needs, depending on the added vitamins and minerals (i.e. calcium, zinc, iron, vitamin D, vitamin B-12, folic acid, protein and fiber).
- Are portable, convenient and pre-packaged.
- May keep you away from unhealthier temptations, such as the vending machine or fast food drive-thru.
- Can help ward off binge eating if you become excessively hungry.
- Have a long shelf life and don't require refrigeration.
Cons
Consider these downsides:
- Excessive nutrients. Energy bars can contribute to an excessive intake of nutrients, especially if you are eating more than one bar daily, are already taking a multivitamin supplement or are eating other fortified (enriched) foods and beverages. The dangers of over-supplementation vary from minor intestinal discomfort (diarrhea and constipation) to liver disease, nerve damage or even death.
- Excessive calories. If eaten too often, energy bars may contribute to a high-calorie intake, which can lead to weight gain.
- Added sugar. Energy bars have a sweet flavor. This can come from several sources, including fruits, fruit juices, calorie-containing sweeteners (sugar, honey, syrups), or artificial sweeteners and sugar alcohols. You’ll have to read the ingredient listing to meet your personal preferences and amounts.
- Cost. At $1 to $2 per bar, this convenience food can quickly become a major grocery expense.
- Abdominal discomfort. Some energy bars (especially low-sugar, low-carb and high-fiber varieties) contain sugar alcohols and alternative fiber sources (inulin, chicory root), which can cause bloating, gas and diarrhea in some individuals. While these ingredients are safe to consume, it's best to monitor your individual tolerance.
- Lack of data. There is very little research to support the actual need for energy bars. While many provide claims regarding weight loss, antioxidants and muscle building, they are not a magical food and should not be used as a constant replacement for whole foods in your diet.
- Processing. Energy bars are a highly processed food, whereas whole, unprocessed foods should be the staples of a healthy diet.
- Additives. Some energy bars contain additional herbal ingredients, weight-loss aids or athletic performance-enhancing aids. There is no data to show that any of these are effective or beneficial to health. There are no standards regarding potency or safety or effectiveness in these supplemental ingredients—and many can result in medication interaction and possibly dangerous side effects.
Meal Replacement Bars
When lunch is out of reach or you want to add more structure to your eating plan, a meal replacement bar can be used on occasion. Adding a piece of fruit, some raw veggies and a serving of yogurt or milk can help round out this quick, on-the-go meal. If replacing a meal, read the nutrition label to find a bar that contains the following nutritional metrics:
- About 200-320 calories
- 10-25 grams of protein
- 4 grams of fiber or more
- About 20-40 grams of carbohydrate
- Fewer than 20 grams of sugar
- 12 or fewer grams of fat
- No more than 30 percent of your RDA for vitamins and minerals

Workout Fuel
Before hitting the gym or starting a long run, your body needs carbohydrates. It is best to avoid protein, fat, fiber and sugar alcohols, all of which can delay the emptying time of the stomach and slow digestion, causing cramps and sluggish energy levels. Energy bars are usually too high in protein, fat, fiber and possibly sugar alcohols to be used for pre-exercise nourishment. Instead, try another quick-digesting food source before exercising.
During your workout, energy bars are not an appropriate refueling choice because aerobic and high-intensity exercises require blood flow to the muscles, not to the stomach for the digestion of foods. After exercising for more than 60-90 minutes, consider a sports drink or sports gel to boost your energy levels, promote hydration and balance electrolytes in the body.
Energy bars may work for low-intensity, very long-duration activities, such as a long, slow hike or bike ride. (During lower-intensity exercise, less blood is diverted to the muscles.)
After your exercise session, your body needs mostly carbohydrates (to replenish glycogen stores in the muscles), some protein (to help repair damaged muscle tissue) and a little fat (for cellular repair). Eating a "real" and complete meal is your best bet. But if you cannot eat a meal within two hours of working out, then an energy bar paired with a glass of water or milk and a piece of fruit is a good option. Look for a meal replacement bar (see examples above) with at least 30 grams of carbohydrates, 10 grams (or more) of protein and 5-10 grams of fat.
