What are protein shakes?
Protein shakes are beverages made by mixing protein powder with water, although other ingredients are often added as well. Shakes can be a convenient addition to your diet, especially when access to high-quality, protein-rich foods is limited. Although most people don’t need them to meet their daily protein needs, they can be helpful if you need to increase your intake for some other reason. You can buy protein powder and mix it yourself, but you can also find many different brands of ready-to-drink protein shakes. Some of the most popular types of protein powder on the market are:
- Whey protein: It is quickly absorbed and derived from dairy products. It contains all the essential amino acids.
- Casein protein: These are slowly absorbed and derived from milk. They contain all the essential amino acids. .
- Soy protein: Plant-based and contains all the essential amino acids. It also contains soy isoflavones, which may provide some health benefits.
- Hemp proteins: Plant-based and high in omega-3 and omega-6 fatty acids, but low in the essential amino acid lysine.
- Rice protein: Low in the essential amino acid lysine.
- Pea protein: Low in the nonessential amino acids cystine and methionine.
Some brands contain a blend of different types of protein powder. For example, many brands combine plant-based proteins to complement each other’s amino acid profiles. Conclusion: Protein shakes can contain different types of protein, each with its own characteristics

Protein shakes reduce hunger and appetite
Protein can reduce hunger and appetite in two main ways. First, it increases levels of appetite-suppressing hormones such as GLP-1, PYY, and CCK, while reducing levels of the hunger hormone, ghrelin. Second, protein helps you feel full for longer. In one study, a high-protein breakfast helped participants consume up to 135 fewer calories by the end of the day. In another, overweight men followed a weight-loss diet, increased their protein intake, and 25% of their total calories. This increase in protein reduced cravings by 60% and cut down on afternoon and late-night snacking. Increasing protein intake from 15% to 30% of total calories helped participants in another study consume 441 fewer calories per day without actively counting calories. What’s more, by the end of the 12-week study period, they had lost an average of 5 kg. These shakes can be a convenient way to add more protein to your diet. However, keep in mind that too much protein can still lead to excess calories. Another study found that shakes containing 20–80 grams of protein all reduced hunger by 50–65%, regardless of the amount of protein in the shakes. So if you’re trying to lose weight, 20 grams per serving of your shake seems sufficient to reduce hunger. Conclusion: Protein can curb your appetite by affecting your hunger hormones. It can also help you feel full longer, which may help you eat less and lose body fat.

Protein shakes can boost your metabolism
A high protein intake can boost your metabolism, helping you burn a few more calories each day. This is partly because a high-protein diet—especially when combined with strength training—can help build muscle. This can speed up your metabolism because muscle burns more calories than fat. In a study involving obese participants, some were given protein shakes containing 0 or 200 grams of extra protein per week. Those who received the protein gained 1.3 kg more muscle mass after a 13-week training program. In another study, researchers gave participants a combination of food and protein shakes containing 1.2 g/kg or 2.4 g/kg per day. After 6 weeks, those on the high-protein diet gained 1.1 kg of muscle and lost 21.3 kg more fat. It should be noted, however, that your ability to gain muscle while on a weight-loss diet may depend on how much muscle you already have. Protein can also boost your metabolism due to the number of calories required to digest and metabolize it. This is known as the thermic effect of food (TEF). For example, 15–30% of the calories from protein are burned during digestion, whereas only 5–10% of the calories from carbohydrates and 0–3% of the calories from fat are burned during digestion. Conclusion: Protein helps boost metabolism because a significant amount of energy is expended to digest and metabolize it. It also helps build muscle, which burns more calories than fat.

Protein shakes can help you lose weight and belly fat
Researchers generally agree that high-protein diets can help you lose more fat, especially belly fat. In one study, participants on a diet providing 25% of calories from protein lost 10% more abdominal fat after 12 months than those who consumed half that amount. In another study, participants who received an extra 56 grams of whey protein per day lost 2.3 kg more by the end of a 23-week study period, even though they did not consciously change anything else in their diet. Another study compared the effects of different weight-loss diets. Participants who consumed Those who ate more protein lost 14.1 kg in 3 months—23% more than those who consumed less protein. In a final study, participants on diets in which 30% of calories came from protein lost 3.7 kg more than those on diets in which 15% of calories came from protein. Conclusion: Protein shakes are a convenient way to increase your daily protein intake. This can help boost fat loss, especially around your waist.

Protein shakes can also help prevent muscle loss and a slowing metabolism
Weight-loss diets often cause you to lose muscle mass, which can slow down your metabolism. This makes it easier to regain all the weight you lost (and more) once you stop dieting. A high-protein intake combined with strength training or weight lifting can help prevent some of this muscle loss and metabolic slowdown. In fact, researchers reported that participants’ metabolism slowed less on a weight-loss diet that provided 36% of calories in the form of protein than on a diet that provided about half that amount. Evidence shows that consuming one protein shake daily as part of a weight-loss diet can effectively help maintain muscle mass up to three times as much. A study was conducted on athletes following weight-loss diets, with one group receiving 35% of calories from protein and the other 15%. Both diets helped participants lose approximately the same amount of fat, but those who consumed more protein lost 38% less muscle mass. A recent review of these studies also notes that weight-loss diets providing more than 1.0 g/kg of protein per day can help adults preserve more muscle and lose more fat. Conclusion: Protein shakes consumed during a weight-loss diet can help prevent muscle loss and a slowing of the metabolism. This is particularly effective when combined with strength training or weight training.

Protein shakes can help prevent weight regain after weight loss
The effect of protein on metabolism, appetite, and muscle mass can also prevent you from regaining the fat you worked so hard to lose. A study reports that participants who consumed more protein lost more weight and maintained their results better than those who consumed less protein. In fact, the high-protein group regained only 9% of the weight they had lost, while the low-protein group regained 23%. Another study of participants who had just completed a weight-loss program found that they received a supplement containing 48.2 grams of protein per day. Participants who took the supplement felt fuller after meals and regained 50% less weight 6 months later, compared to those who did not receive any supplement. Another study observed similar effects with a supplement providing just 30 grams of protein per day, demonstrating that more isn’t necessarily better. Conclusion: Additional protein, whether from shakes or whole foods, can help minimize weight regain after weight loss.

What kind of protein is best?
Different types of protein have different effects on the body. For example, whey is absorbed more quickly than casein and helps reduce hunger in the short term. One study reported that 56 grams of whey protein per day helped overweight and obese participants lose 2.3 kg more fat than the same amount of soy protein. Another study describes whey as three times more effective at maintaining muscle-building capacity during a weight-loss diet than soy protein. That said, not all studies agree that whey is superior. For example, one report notes that while whey protein has rapid effects on reducing hunger, there is no difference in the number of calories consumed at meals. Furthermore, several studies indicate that fat loss is the same whether whey, soy, rice, or egg protein supplements are used. A final factor to consider is protein quality. Whey, casein, and soy all contain the essential amino acids the body needs. On the other hand, rice and hemp protein are low in the essential amino acid lysine, and pea protein is also low in the nonessential amino acids cystine and methionine. That said, these deficiencies are unlikely to cause a health problem unless your shakes are the only source of protein in your diet. Furthermore, many plant-based protein powders are blended from different sources so that the mixture contains all the essential amino acids. Conclusion: The exact type of protein powder you use in your shakes shouldn’t make a significant difference for fat loss. Some studies show an advantage for whey, but the evidence is mixed.

Dosage and Side Effects
Drinking one smoothie a day is a good way to start. It's best to drink it either before or instead of a meal, with 1 or 2 tablespoons of protein powder in the smoothie. Mixing it with water, ice, and perhaps a piece of fruit in a blender is an easy way to make a delicious and satisfying smoothie. Side effects such as bloating, cramps, gas, and diarrhea may occur if you are lactose intolerant and drink shakes made with whey or casein. These symptoms can be easily avoided by switching to non-dairy protein powders, such as egg, pea, soy, hemp, or rice protein powders. It’s worth noting that high-protein diets were once thought to have negative effects on kidney and bone health, but the most recent research shows that this is not true. In fact, high protein intake has been shown not to cause any kidney damage in healthy people. However, Low-protein diets may be beneficial for people with kidney problems. Protein is also an essential nutrient for bone formation and maintenance, and reviews of the research show that there is no reason to restrict protein intake to improve bone health. Most studies indicate that total protein intake of between 1.2–2.2 g/kg per day provide beneficial effects for weight loss. This amount of protein typically accounts for about 25–35% of the calories you consume in a day and is generally considered safe. How much protein should you eat per day? Conclusion: Having one shake per day is a good place to start, with 1 or 2 tablespoons of protein. Some people may experience digestive side effects.
