Benefits of a High Protein Diet: Is it Good for Weight Loss?

Benefits of a High Protein Diet

Are the health benefits of a low-carbohydrate, high-protein diet good for Weight Loss? The high protein, low carb diet swaps much of your daily carb intake for protein. Although there’s no set macronutrient ratio, this eating pattern is based largely on the allotments of the two diets that inspired it.

For example, low carb diets typically restrict carb intake to under 26% of total daily calories, or fewer than 130 grams of carbs for someone following a 2,000-calorie diet — while very low carb diets slash that number to under 10%. On the other hand, high protein diets often pack significantly more than the Recommended Daily Allowance (RDA) for protein, providing at least 0.6 grams of protein per pound (1.3 grams per kg) of body weight.

Some boast over 1.4 grams of protein per pound (3 grams per kg) of body weight — the equivalent of 204 grams of protein daily for a 150-pound (68-kg) person. High protein, low carb diets may be higher in fat to compensate for the carb deficit. For instance, a 2,000-calorie version may contain 26% carbs, 40% fat, and 34% protein — equating to a daily protein intake of 170 grams for a 150-pound (68-kg) person.

However, while some people, such as bodybuilders and athletes, pay close attention to macronutrient ranges when following this diet, many individuals simply cut carbs and replace them with high protein foods. Aside from that, some people follow less strict versions that contain 30–35% carbs — although these are technically considered moderate in carbs.

Types of High Protein, Low Carb Diets

one of the benefits of consuming a high protein diet is that you will feel better and more alert.

Some of the most popular commercial diets commonly considered high in protein and low in carbs don’t truly fit into both categories. Notably, many people regard the Zone Diet and Sugar Busters Diet as high protein, low carb. However, these diets are moderate in carbs, as they typically provide about 40% of calories from carbs.

Additionally, many popular low carb diets, such as Atkins and ketogenic diets, are not considered high protein, low carb. Instead, they’re high fat, low carb or high fat, very low carb, and they only contain moderate amounts of protein.

In fact, no branded diets are known to conform to this pattern. If you’re interested in a strict high protein, low carb diet, you may need to count calories, protein, carbs, and fat to stay within your macronutrient ranges. This can be difficult, so most people that choose the Balanced Diet, prefer to loosely follow a high protein, low carb diet by replacing high carb foods with protein sources.

Health Benefits of a High Protein, Low Carb Diet

Although people who lead sedentary lifestyles require less protein, physically active individuals, athletes, and pregnant women need significantly more than the current RDA of 0.36 grams per pound (0.8 grams per kg) of body weight. As such, the benefits of a high protein diet are many — as well as low carb eating patterns, which are often associated with weight loss. Thus, combining the two diets may give numerous advantages.

Weight Loss

Protein is the most filling macronutrient and helps decrease hunger and food intake, two effects that promote weight loss. In particular, foods high in protein boost levels of fullness hormones while lowering levels of hunger hormones like ghrelin.

Research has shown that meals comprising 25–81% of calories from protein increase feelings of fullness, meaning that even moderate protein diets may reduce hunger levels.

High protein diets also help enhance the thermic effect of food, or the calories burned during digestion. This may be due to the greater oxygen demand required to break down protein-rich foods.

Additionally, high protein, very low carb eating patterns have been shown to enhance the secretion of glucagon, a hormone produced by the pancreas that’s known to enhance fullness.

These diets also lead to higher ketone body production, particularly of beta-hydroxybutyrate (BHB). Your liver produces ketone bodies when glucose availability is reduced. Studies show that increased BHB levels help suppress appetite.

Interestingly, a small 4-week study in men with obesity demonstrated that a reduced-calorie, high protein, very low carb diet providing 30% protein and 4% carbs led to more weight loss than a high protein, moderate carb diet providing 30% protein and 35% carbs.

On average, the men in the high protein, low carb group lost 15 pounds (6.75 kg) while those in the moderate carb group lost 10 pounds (4.32 kg).

Many other studies reveal that high protein, low carb diets are more effective for weight loss than those higher in carbs and protein. Still, total calorie intake and calorie burning are the most important factors for weight loss.

Body Composition

When you lose weight, it’s normal to experience significant decreases in muscle mass. Yet, this loss can gradually lower your metabolism, as greater muscle mass increases the number of calories you burn while at rest. High protein diets can help preserve muscle mass during weight loss and may even increase muscle mass.

Increasing protein intake while cutting 500–750 calories per day has been shown to maintain muscle mass while promoting fat loss. However, this effect is lost during more severe calorie restrictions, such as during poorly planned, very low-calorie diets. Additionally, studies show that combining a high protein diet with exercise can boost fat loss while building lean body mass.

In a 4-week study we conducted, 20 men who exercised intensely 6 days per week ate either a high protein diet of 1.1 grams per pound (2.4 grams per kg) of body weight or a control diet. Both diets provided 40% fewer calories than their energy needs and around 50% of calories from carbs. Those following the high protein diet lost more body fat and gained about 3 pounds (1.2 kg) of muscle mass, while the control group’s muscle mass stayed the same.

Other studies note that yet another one of the benefits of a high protein diet promotes increased or stable muscle mass during weight loss for both men and women, compared with lower protein diets. Plus, eating a low-calorie, high-protein diet has been shown to help athletes gain muscle mass during training.

Another study in 48 athletes found that those who ate a minimum of 1.4 grams per pound (3 grams per kg) of body weight combined with heavy resistance training gained significantly more muscle mass and less body fat than those who followed their normal diets. These results occurred despite the high protein group consuming 490 more calories per day than the control group. Low carb diets have likewise been shown to help reduce fat mass while maintaining muscle mass.

Other Potential Health Benefits of a High-Protein Diet

High protein, low carb diets may also aid the following:

  • Blood sugar regulation: Both high protein and low carb eating patterns have been shown to improve short- and long-term markers of blood sugar control.
  • Heart disease risk: This diet may reduce heart disease risk factors like high triglyceride and high blood pressure levels, though some research links high protein diets to increased heart disease risk.
  • Bone health: Research indicates that high protein diets may help prevent bone loss and reduce fracture risk in older adults.

High-Protein Foods to Eat

Eating mostly whole, nutrient-rich foods is best on a high protein, low carb diet — as with any healthy diet. You’ll generally want to up your intake of protein.

Foods to eat on this diet include:

  • Eggs: whole eggs and egg whites
  • Fish and shellfish: cod, flounder, clams, shrimp, etc.
  • Meats and poultry: bison, chicken, turkey, etc.
  • High protein vegetarian foods: tofu, edamame, and other soy foods
  • Dairy: high protein dairy products like Greek yogurt and cottage cheese
  • Non-starchy vegetables: broccoli, cauliflower, greens, peppers, asparagus, mushrooms, etc.
  • Nuts and seeds: almonds, pumpkin seeds, sunflower seeds, peanut butter, chia seeds, and hemp seeds
  • Condiments: fresh herbs, pepper, spices, etc.
  • Beverages: water, sparkling water, unsweetened herbal tea, unsweetened coffee, etc.

Fruits, starchy vegetables, and high protein grains like quinoa can be enjoyed in moderation depending on your level of carb restriction. Fat intake also depends on your individual dietary regimen. Egg yolks, avocado, nut butters, fatty fish, and olive oil are good choices for healthy fat sources.

Foods to Minimize

When following a high protein, low carb diet, it’s important to reduce your intake of carb-rich foods. You should limit the following:

  • Grains and starches: breads, rice, pasta, baked goods, cereals, etc.
  • Sweeteners: sugar, agave, maple syrup, honey, coconut sugar, etc.
  • Sugary drinks: juice, sweetened coffee and tea, soda, sports drinks, sweetened alcoholic beverages, beer, etc.
  • Processed, high carb foods: French fries, fried chicken, pizza, chips, etc.

You can include healthy, high-carb foods like starchy vegetables and fruits in moderation. Remember that your total carb intake depends on your desired macronutrient ranges. Depending on your macronutrient goals, you may also need to reduce your intake of high fat foods like fatty meats and oils.

Final Thoughts

Final thoughts on the health benefits of a high protein diet.

The high protein, low carb diet has no one set definition but may be best for people like athletes who want to promote weight loss while preserving or increasing muscle mass. Although this eating pattern may have other benefits, some research links it to downsides. Plus, the amount of protein that it encourages is likely unnecessary for most people.

If you’re looking to optimize your overall health, I’ll advise you to focus on eating whole, nutrient-dense foods, restricting your intake of added sugar and processed foods, getting plenty of exercise, and decreasing your stress levels.
