Protein Bar Buying Guide & Recommendations

The healthiest protein bars will not only include a good amount of protein but also have a good taste. The last thing you want to do while dieting is having to eat bars that taste like cardboard. The best protein bars to lose weight will usually include some extra vitamins or minerals and have a moderate amount of sugar. Try to avoid bars that have over 350 calories since they can quickly add to your daily intake unless you eat them after doing exercise.

  • Taste - You should enjoy your protein bars, so get the ones that best suit your palate. Chocolate is available in almost all the top protein bars, but you could always try some different flavors such as peanut butter, or birthday cake.
  • Protein - The whole point of buying a protein bar is to have a convenient way of ingesting protein. However, you’d be amazed by how many of them have almost zero protein contents. Make sure you get at least 5 grams in each bar; the healthiest protein bars will contain at least 10g, and the more, the better. Milk and whey are the best kinds because soy can upset your stomach if you are sensitive to it.
  • Sugar - If you are trying to lose weight, sugar is the worst thing you can eat. Some bars can contain as much sugar as a Milky Way chocolate, so look for the ones with less than 8g per serving. Remember, you are trying to lose weight, and a protein bar should not be considered a treat or a sweet snack.
  • Calories - The Best protein bars for women will contain up to 200 calories, while the ones for men will have up to 300. If you eat the bar after doing exercise, when your body can use more calories, women can up the dosage to 300 calories, and men can go up to 380.
  • Sugar Replacements - Some bars will use artificial sugar sweeteners to make up for the low sugar content. Don’t eat these bars, they can cause unpleasant side effects like headaches or joint pain, and can be as addictive as sugar.
  • Vitamins & Minerals - Even tough you should focus on the protein content, having additional minerals and vitamins never hurts and can be a healthy plus. The best protein bars can also contain antioxidants to help support your immune system.
Want to gain muscle?

After doing exercise your body is craving for protein to feed the muscles. It is not always possible to eat a proper meal after going out for a jog or spend somse time at the gym, so having a protein bar on hand is a great alternative. Keep some bars stocked inside your gym bag and have one as soon as you finish your workout. Your body will thank you for it and soon your muscles will start to build up.

Not all protein bars are healthy. Just because it has the word protein in it doesn’t mean that the bar you are eating is good for you. Canola oil and cornstarch can be added as ingredients which can bloat you or cause discomfort. The less amount of ingredients listed, the better. You want your bar to be simple and easily digestible.
