However, when your goal is to lose weight, not all protein powders are created equally. Many protein powders are full of…umm, well, they are full of protein, but often other unnecessary additives. While consuming protein can help you build muscle when you work out, it won't necessarily make the scale start a downward trend. Additionally, some protein powders are high in calories or have added sugars, which is problematic when you are aiming for weight loss. Therefore, it is important to pay close attention to labels in order to ensure that your protein powder of choice is the right fit for you.
To help you meet your goals, our ACTIVE Reviews Team has rounded up the best protein powders for weight loss.

How Do Protein Powders Help with Weight Loss?
The simple answer to how protein powder helps with weight loss is that higher protein diets are linked with more weight loss than standard or lower protein diets.(5) And protein powders are an easy and convenient way to meet your increased protein needs. One recent study compared the weight loss of people with metabolic syndrome. They divided them into two groups and gave one group a low-calorie diet with a standard amount of protein, and the second group a low-calorie diet with a high amount of protein. The group given the high-protein diet lost significantly more weight than the group given the standard amount of protein.(6)
Results like these are likely due to a few reasons. The first is the thermic effect of food, which is an increase in calorie burn after eating certain meals.(7) We know that eating protein causes the body to burn more calories than eating carbohydrates or fat. We also know that protein helps to preserve lean body mass (muscle) even during fat loss. Muscle stores help keep resting energy expenditure, or calories burned while at rest, higher than they would if the muscle was lost.(5) High-quality protein powders are a great resource in ensuring protein needs are met throughout the day.
FAQs About Protein Powders for Weight Loss
Should I use protein powder if I want to lose weight?
Protein powder can definitely help you lose weight. In fact, protein powders have been shown to help lose fat while maintaining the muscle you currently have.(8) It's a good idea to choose one that is high in protein, but lower in calories. If possible, consider sticking to water as your mix-in to avoid increasing overall calorie intake.
Does protein powder help you lose belly fat?
Protein powder does help you lose belly fat, but not by targeting this one area. Unfortunately, there is no way to target fat loss in any area of the body without surgery. Protein will help you to stay full longer, which will keep you from reaching for convenient foods, and also aid in weight loss. When you lose weight, you will naturally lose belly fat, as well.
How many protein shakes should I drink a day to lose weight?
When determining how many protein shakes to drink per day, first determine your protein and calorie goals for the day. Once you have a goal, you can more easily figure out how many protein shakes you can have based on your calorie limits. Although it can vary from person to person, one to two protein shakes per day is the most common.
Should I drink protein before or after a workout?
Protein is an essential nutrient when it comes to repairing the muscles that you have used in your workout. Therefore, many people prefer to drink them after they exercise. However, there are benefits to drinking protein before a workout, as well. Because of the varying benefits, current recommendations put forward by the International Society of Sports Nutrition are more focused on meeting daily overall protein needs regardless of when the protein is consumed.(9) It comes down to personal preference and how well you are able to digest protein powder.
