A 2024 study of 44 people showed that a calorie-restricted diet and supplementation of 30 g of milk protein concentrate for 8 weeks was associated with:

Studies show that increasing your intake of protein can benefit weight loss through several mechanisms.

For starters, it can increase your metabolism, according to a 2020 review article, which can bump up the number of calories that your body burns throughout the day.

Studies have found that protein may also reduce calorie intake and hunger by modifying levels of certain hormones involved in appetite control, including ghrelin and leptin.

One 2022 study of 70 adults with obesity showed that compared to a control group, consuming higher amounts of plant protein for 12 weeks led to:

  • weight loss
  • decreased body fat mass
  • reduced IL-1β levels (a protein that can promote chronic inflammation in excess)
  • decreased tumor necrosis factor-alpha (TNF-α) levels (a protein related to inflammation, immune response, and cancer)
  • decreased leptin
  • reduced caloric and carbohydrate intake
  • decreased fat intake

However, while protein may help support weight loss, it’s important to consider the other ingredients in your protein shake.

Although ingredients like nuts, seeds, dark chocolate, and nut butter may be nutritious in moderation, they’re also very calorie-dense and could cause weight gain if consumed in high amounts.

Moderating your intake of these ingredients can help keep the calories from stacking up and turning your protein shake into a high calorie indulgence.

However, protein shakes alone cannot promote weight loss. They must be consumed within the context of a balanced dietary pattern that provides an overall caloric deficit in order to be an effective tool for weight loss.

Summary

Increasing your intake of protein could support weight loss. However, some ingredients in your protein shake may be high in calories, which could lead to weight gain if consumed in excess. Protein shakes also cannot be used alone to promote weight loss.

Drinking a protein shake first thing in the morning may be especially beneficial for your workout routine, in addition to promoting weight loss and rounding out your diet.

Protein is necessary for muscle growth. It can even help your body recover after an intense workout.

A 2022 meta-analysis of 74 clinical trials reported that getting enough protein in your diet may also help with muscle gains and increase lower body strength from resistance training, making protein shakes particularly beneficial for bodybuilders who want to increase muscle mass.

Interestingly enough, one 2019 study of 43 people found that consuming a carbohydrate-protein supplement either before or after performing high intensity resistance training led to no observed significant differences in body composition.

The study found that the groups that drank a protein shake before or after working out experienced greater increases in upper body strength than the control group, which did not drink a protein shake at all.

Therefore, drinking a protein shake before or after hitting the gym in the morning could be a useful tool for reaching your fitness goals.

Summary

Protein supports muscle growth and recovery. It may also help maximize muscle and strength gains from resistance training.
