How To Choose The Best Protein Bar For Weight Loss And Muscle Gain?
Serving per container
The key to weight loss is losing fat while maintaining your muscle mass. You will also lose some water and have glycogen depletion when cutting carbs.
All of this means you have to pay attention to what’s served inside the container, including the ingredients and their amounts.
First of all, you need more protein than normal, and you need to ingest it every few hours as protein isn’t stored in your body like fat and carbs, it needs replacing every day.
As the most abundant component in the body, protein is used for hundreds of functions and has to be taken consistently.
In addition, as you’re trying to gain muscle, you need an anabolic environment, which means a positive metabolic state. Thirdly, consuming protein results in protein synthesis, which is basically the biological process to replace cellular proteins. This is among the things that help your muscles grow.
All these things are meant to tell you that the intake amount of protein is important. Most protein bars use milk, whey, or soy as the source of protein.
The best-quality protein bars contain 20-30 grams of this ingredient while good bars contain 15 grams or more. This is what you should look for when choosing this type of food.
In addition to protein, you will also need fat, carbs, fiber, and calories.
The fat offered in protein bars is healthy fat from seeds and nuts. But you should take in much if you want to lose weight and build muscle, so choose bars with a little fat only.
There are complex carbs that take time to break down in the body, which is healthy as they do not store as fat. It’s best to go with protein bars with around 25 grams of carbs.
Fiber is another essential ingredient to seek when choosing a protein bar. In this case, you should buy ones that have a large amount of fiber for losing weight and gaining muscles.
How many calories you take in affects the entire body, especially when you want to lose weight. You may want to consider getting only 150-200 calories from a protein bar.
Convenience
One of the best things about protein bars is that they can provide you with a snack or a light meal while being very compact and portable as you can carry several bars with you easily. Depending on how long you will be away from home, you can bring 1 or 2 bars with you.
Ingredients
When it comes to the ingredients, it’s important to know if they are natural or not. In fact, it’s nearly impossible to find a protein bar with only natural ingredients as they all undergo processing.
So, what really matters here is their influences on how you feel after you consume the bar. Before deciding to go with a specific type, you should try several bars and see how your body reacts.
For example, extra fiber or sugar alcohols can lead to digestive discomfort, so pay attention to this when you are choosing protein bars.
