Best Low-Calorie Protein Powder

Building muscle mass while losing weight is not an easy thing to do. 

Apart from a combination of proper diet, discipline, and exercise, increasing your protein intake is necessary for muscle building and recovery. This is especially true for gym enthusiasts or anyone who is struggling to meet their daily protein requirement. 

While protein powders provide a convenient way to get more protein, choosing a low-calorie protein powder is essential to help you stay on track on your weight loss journey. 

Low-calorie protein powder is also best for those who are on a low fat and low carbohydrate diet. Since they contain high amounts of protein, they can make a person full and satisfied for longer hours, hence, prevents you from overeating, helping you lose weight, and curbing hunger. 

With that being said, let’s drill down on some low-calorie protein powders that you can add to your diet to achieve that muscle mass while burning some fats for a healthy and toned body.

What to Consider When Buying the Best Low-Calorie Protein Shake

1. Check its ingredients and nutrient profile

With so many low-calorie protein shakes in the market, it is important to check the ingredients before buying one. 

When trying to lose weight and build a better physique, the most important things to look at are the calories content per gram of protein, fat, carb, and sugar components.

Further, while it may be beneficial for you to choose one with focused ingredients, you may also want to consider protein shakes with added vitamins and minerals, so you can build a good-looking body, leaner and stronger muscles, and also a stronger immune system, and a healthier overall body condition.

Also, milk-based proteins such as whey, casein, or egg-based contain all nine essential amino acids, but if you‘re a vegan and would want a plant-based protein, best to look for a combination of blends to get all the essential amino acids. 

Lastly, might as well, choose ones from natural or organic sources. 

2. Flavorwise

Unsweetened and unflavored ones may be better for you so you can consume less sugar, artificial additives, and sweeteners. 

Healthier choices often mean unpleasant taste, especially for plant-based foods or drinks, but it is not always the case with protein powders. A variety of flavors are also available, though some contain artificial sweeteners and preservatives. But with these flavored protein powder choices, your weight loss journey can still be a fun and enjoyable experience!
