What is Keto-Feindly Bar?

A protein bar helps you stick to your keto diet because it contains the right proportion of nutrients. The low carbs, medium proteins, and high fat allow you to maintain ketosis.

Remember that not all keto bars are equally good. Apart from the high-fat, low-carb content, you need enough fiber and protein.

Some bars can contain sugar alcohols. While this substance doesn’t add to your total carb count, it can cause abdominal pain and cramping.

Choose a product with natural ingredients, especially plant-derived healthy fats that are better for your cardiovascular health, and look for FDA-approved products.

Nutrition Facts / Main Ingredients in Keto Bars

As you’ve seen from the products I’ve reviewed above, protein bars are manufactured with different ingredients.

The nutrition facts have to resemble what you need for your keto diet. Look for protein bars that contain about:

  • 70% fat
  • 20% protein
  • 10% carbs or less

IngredientsCheck the vitamins and minerals added to your protein bar because keto-ers are one step away from malnutrition if they don’t use vitamin supplements.

If you need a bar high in protein, it probably means you’re working out.

The most important vitamins and minerals to fuel your workout and improve your focus are calcium, magnesium, vitamin C, and vitamin B complex.

Regarding the ingredients, you need:

  • A quality source of healthy fats, such as olive oil, avocado, seeds, nuts, or cold-pressed coconut oil
  • Natural, whole-food ingredients for the protein such as grass-fed cattle, eggs, wild fish or even collagen protein powder from bone broth
  • Medium-chain triglycerides that convert quickly into ketones to give you a quick energy boost
  • Limited or no preservatives, processed fats, or artificial aromas and colors

When to Eat Keto Protein Bars?

The best time depends on your purpose. So ask yourself this: why do I want a protein bar?

  • I don’t have time to eat breakfast. You can use your protein bars in the morning instead of your breakfast at home, although you’ll probably need to eat a more comprehensive meal later on during the day.
  • I want something to munch on between meals that don’t throw me off ketosis. Keto bars are healthy and satiating, so they keep you full until it’s time to have your next meal. With their perfect proportion of fats, protein, and carbs, they will give you a lot of energy too.
  • I want to lose weight. Then you can replace one of your meals entirely with a keto-friendly protein bar. Because these bars are satiating and lower in calories than a normal keto meal, you can use them to reduce your daily caloric intake with no hunger pangs.
  • I want to get fit. These bars will boost your energy, and therefore increase your endurance in the gym if you eat them about an hour before your workouts. If you want to help your muscles heal faster, so you can work out again quickly, eat a bar after your workouts.

How to Make DIY Protein Bars Recipes:

Homemade low-carb protein bars aren’t difficult to make. You’ll need quality, ketogenic-friendly ingredients that pack healthy fats and are low in carbs. Focus on seed or nut butter, almond or coconut flour, and organic protein powders.

Are Low Carb Protein Bars Good for You?

The short answer is yes, but the long answer depends on several factors. Here’s what you should consider:

  • Your daily caloric limit. If you’re on a calorie-restriction diet to lose weight, remember that bars pack a lot of them, so you should probably stick to one or two each day. If you’re trying to gain weight, you can eat three or four, depending on your other macros.
  • Your daily carb limit. Count your carbs because you need to eat very few of them if you want to keep up with your ketosis. While a protein is great after a strenuous workout to restore your muscles, and high-intensity cardio activities can burn some of the extra carbs, you still need to count your macros.
  • Your daily protein limit. Keep in mind that the best keto bars for weight loss will have twice as much protein as carbs.
  • Allergenic ingredients. Check that the product you’re getting doesn’t have anything you’re allergic to, such as peanuts or dairy. Some people have a bad response to sugar alcohols, which trigger abdominal cramping and gas.
  • Eco-friendly ingredients. Look for eco-friendly ingredients to protect your health and the environment — products like ProSource Protein Bars that use palm oil damage the tropical forests.

Keto Bars Review: Final Thoughts

All these keto bars above are really good for different purposes. For instance, Quest Nutrition is the cleanest, healthiest choice for gym rats, RXBar snacks are good meal replacements, Bulletproof Keto Diet Protein Bars give you instant energy, and Orgain Organic Protein Bars are the best for vegans.

But read those negative points about these bars, and you’ll see things related to their carb content, the use of artificial ingredients, or low fibers, fat, or protein.

Perfect Keto Bar is the best choice because it has all the pros and none of the cons, except some complaints about the taste. And we all know how subjective the matter of taste is.

Remember that Perfect Keto uses only natural, clean ingredients, it’s a fat-bomb, it keeps you satiated, it doesn’t cause glucose spikes, and it’s improved with tapioca fiber.

What is tapioca fiber all about, you ask? This superfood is proven to improve your digestion and heart health, which is why you need it on keto.
