10 Best Protein Powders For Weight Loss, According To a Dietitian

When it comes to losing weight, the main goal is to create a negative calorie balance. While adding calorie-containing supplements to your diet during weight loss might seem counterintuitive, the best protein powders can be incredibly beneficial.

Generally, when losing weight, you don't need to take any type of supplement because you're trying to reduce calories and not add calories to your diet; however, protein powders for weight loss, especially those low in carbs and calories, can enhance satiety and help you retain lean muscle mass while shedding fat. Protein, being slow to digest, helps keep you fuller for longer, making it a valuable tool in any weight loss journey.

Why Protein Powders Are Effective for Weight Loss

Protein powders are effective for weight loss for several reasons. Studies have shown that dieters who include whey protein supplements often lose more body fat and maintain or gain lean muscle than those who don't. Retaining lean tissue when losing weight is critical as lean tissue helps to keep your metabolic rate higher.

• Enhances Satiety: Protein is slow to digest, which helps you feel full for longer periods. This reduces overall calorie intake by curbing hunger and decreasing the likelihood of snacking on high-calorie, low-nutrient foods between meals.

• Preserves Lean Muscle Mass: Maintaining lean muscle is essential during weight loss because muscle tissue burns more calories at rest than fat tissue. By preserving muscle mass, protein powders help keep your metabolic rate higher, making it easier to lose fat.

• Supports Muscle Recovery and Growth: Protein powders aid muscle recovery and growth after exercise. This is particularly beneficial for those engaging in regular physical activity during a weight loss journey, as repairing and building muscle can further enhance metabolic rate and improve overall body composition.

How Much Protein Do You Need To Eat Per Day for Weight Loss?

Determining the right amount of protein to consume daily is crucial for effective weight loss.

While the Recommended Dietary Allowance (RDA) for protein is 0.8 grams per kilogram of body weight, a European Journal of Sport Science study on athletes trying to lose body fat suggests that higher protein intake (2-3 times the RDA) can help optimize body composition to lose fat and maintain or gain lean tissue.

Individuals looking to lose weight should aim for a protein intake of at least 0.8 and up to 1.6 grams per kilogram of body weight. This range helps support satiety, muscle retention, and overall metabolic health. For a 150-pound person, this equates to 54 to 109 grams of protein per day.

Types of Protein Powders

Low-carb protein powders good for weight loss come in various forms, each with its unique benefits:

• Whey Protein: Derived from dairy, it is quickly absorbed and highly effective for muscle recovery and growth.

• Casein Protein: Also from dairy, it is slower to digest, making it ideal for sustained satiety.

• Collagen Protein: Known for supporting joint health, it is a good alternative for those avoiding dairy.

• Plant-Based Proteins: Common sources include pea, soy, and rice, suitable for vegans and those with dairy allergies.

Key Factors to Consider When Choosing a Protein Powder for Weight Loss:

When choosing a protein powder to help you lose weight—or keep it off—here are three criteria.

• Limit calories to no more than 160 per serving. Keep calories as low as possible for your weight-loss protein powder. If you can find one that is 120-160 calories, that is ideal.

• Minimize added sugar. The best protein powders in our guide have up to 1 teaspoon (4 grams of added sugar). If your protein powder has more than 4 grams of added sugar, skip it.

• Lower Carb Counts. Your protein supplement helps you get more protein in your diet, not carbohydrates. The total carbohydrates should be no more than 10 grams (40 calories).
