What Is A High-Protein, Low-Carb Diet?

A high-protein, low-carb (HPLC) diet limits your carbohydrate intake and focuses on higher protein consumption. However, there is no strict rule for how much protein or carbs you should eat, and it can vary from person to person.

For a diet to be considered low-carb, it should have less than 130 grams of carbs per day or carbs should make up less than 26% of the daily macronutrient intake (1). High-protein diets require you to have more protein than what is usually recommended. As per the Recommended Dietary Allowance (RDA), the required amount of protein is about 0.8 grams per kilogram of body weight (2). So, on a high-protein diet, you may consume between 1.8 and 3 grams of protein per kilogram of body weight each day (3).

In a 2,000-calorie high-protein, low-carb diet, you may eat 26% carbs, 40% fat, and 34% protein (of the daily macronutrient intake). Someone weighing 150 pounds (68 kilograms) should aim for around 170 grams of protein each day.

Protein and carbohydrates are two essential macronutrientsi  The essential nutrients that your body requires in large quantities to maintain overall health and function optimally. necessary for a balanced diet. Let us find out how they help in the functioning of your body.

Role Of Protein And Carbohydrate In The Diet

Protein is a major component of the skin, muscles, bones, organs, hair, and nails. Dietary protein helps prevent lean body massi  The total weight of your body minus all the weight attributed to fat, such as muscles, bones, organs, skin, and fluids. loss and promotes the growth and repair of the body (2). Moreover, adding high-quality protein to every meal may encourage muscle protein production, support muscle well-being, and help maintain lean body mass as you grow older (4).

protip_icon Did You Know?
The human body contains around 1,00,000 different types of proteins made from different combinations of 20 amino acids (5).

Carbohydrates are crucial for the body as they provide energy to all the cells in the body as well as dietary fiber (6). The digestive tract begins to break down carbohydrates into glucose, the main energy source for the body, brain, and central nervous system, upon consumption (7). They also help manage blood sugar levels, play a role in cholesterol and fat processing, and aid digestion. Learn more about the benefits of a high-protein, low-carb diet in the next section.

Benefits Of A High-Protein, Low-Carb Diet

1. Aids In Weight Loss

According to a study, low-carbohydrate diets are effective at improving weight loss, HDL, and triglyceridei  A common type of fat found in your blood. It is derived from the foods you eat and the fat your body creates from excess calories. levels (8). A low-carbohydrate diet may increase insulin sensitivity and decrease serum insulin concentration, which are associated with increased satiety. Likewise, a high-protein diet also has weight-loss effects and may prevent weight regain. Protein increases the levels of hormones that help in increased satiety signaling, leading to reduced food intake (9).

Another study found that people with obesity who followed a low-carb, high-protein diet providing 30% carbohydrate, 30% protein, and 40% fat achieved a 4.8% weight loss (10). This may be because low-carb diets can produce a higher metabolic burn than high-carb diets. Research shows that a low-carb diet offers a metabolic advantage of approximately 200 to 300 more calories burned compared to an isocaloric high-carb diet (11). Therefore, this is an effective short-term plan for weight loss.

2. May Manage Blood Sugar Levels

A high-protein diet containing low to moderate amounts of carbohydrates increases insulin secretion and glucose uptake, thus improving insulin sensitivity (12). In a study conducted on people with type 2 diabetes, an improved glycemic responsei  The level and speed at which your body's blood sugar levels react after you consume carbohydrates from food. was observed. The serum insulini  Refers to the concentration of the hormone insulin in the liquid component of your blood, i.e., serum. was decreased and plasma glucagoni  A peptide hormone produced by the alpha cells of the pancreas and present in the liquid component of your blood, i.e., plasma. was increased. Thus, this diet may help manage glucose levels in people with untreated type 2 diabetes (13).

Low-carb diets are based on the idea that reducing insulin levels, a hormone that promotes fat storage, may enhance heart health, aid in weight loss, and improve metabolic function (1). Dietary carbohydrates increase insulin needs, and reduction of carbohydrate intake can improve glycemic control. Thus, people reducing their carbohydrate intake may also be able to improve their sugar levels and manage diabetic conditions. However, more research is required to prove all these claims about high-protein, low-carb diets.

3. May Control Triglyceride Levels

High triglyceride levels lead to an increased risk of cardiovascular diseases and obesity (14). A study conducted on men and women with obesity found that the consumption of a low-carb, high-protein diet resulted in weight loss and helped reduce plasma triglyceride levels in the blood, mainly due to salt and water loss and caloric restriction. However, the same study reported an increase in LDL (bad) cholesterol, uric acid, and free fatty acid levels (15). Thus, more research is required to understand the effects of a high-protein, low-carb diet on cholesterol levels.

4. May Help Maintain Muscle Mass

A low-carb and high-protein diet may help decrease fat mass and increase lean body mass. Basically, this diet can reduce the loss of muscle mass and increase the loss of body fat during weight loss, thus maintaining muscle mass during periods of restricted energy intake. It also increases muscle protein synthesis (16).

Since both protein and carbohydrates are equally needed to improve your health and fitness level, it is important to know which foods to include in your diet. Check out a high-protein, low-carb foods list in the next section.

How To Stay Healthy On A High-Protein, Low-Carb Diet

Here are a few tips for staying healthy on a high-protein, low-carb diet:

  • Consume plenty of fiber to maintain optimal digestive health. Dietary fibers help slow down digestion, making you feel fuller for longer, and control blood sugar levels and cravings. Low-carb foods like oats, barley, legumes, peas, beans, broccoli, carrots, and most root vegetables are high in fiber (17).
  • Always ensure you add enough protein through plant- and animal-derived sources rather than supplements and powders. Always consult your doctor before taking any supplements or protein powders.
  • If you are new to this diet, make sure you transition to it slowly. A very low-carb diet may not be suitable for you. Start with a more moderate low-carb, high-protein diet. It will help you get adjusted to the new dietary pattern and avoid the fatigue associated with a sudden transition.
  • Keep yourself hydrated with water-rich vegetables and low-carb beverages like herbal tea, normal water, and lime water. It will promote digestion and make you feel fuller for longer (18).
  • Following a consistent exercise routine along with this diet plan will help improve your health in several ways.

There are no set rules for a high-protein, low-carb diet. It can be incorporated into a variety of diets. Let us find out which other popular diet style suits this eating pattern.

How A High-Protein, Low-Carb Diet Compares To Other Diets

  • Intermittent Fasting: It focuses on weight loss via restricting your eating time period. You can eat only for 8 hours and fast for the remaining 16 hours. Since it is a time-restricted diet style, you can pair a high-protein, low-carb diet with intermittent fasting.
  • Keto Diet: It requires the intake of macronutrients in a very specific ratio to reach and maintain ketosis so you can lose weight. In this diet, carb intake is very low and protein intake is at a moderate level.
  • Atkins Diet: Though it is a low-carb diet that requires a higher protein intake than the recommended amount, it is not a high-protein diet. It involves only a moderate amount of protein, and the macronutrient range also changes as the diet progresses.
  • Mediterranean Diet: It is rich in whole, nutrient-dense, and high-carb foods like beans, vegetables, and nuts and is not a low-carb or high-protein diet. Therefore, you may not be able to combine the two diets.

While a high-protein, low-carb diet certainly offers certain benefits, following it for a long period may result in some health complications. Learn more about them in the next section.

Risks Of Following A High-Protein, Low-Carb Diet

Though this diet is generally considered safe and effective for a short period, it may not be the same in the long run. Low carbohydrate-high protein diets, when followed regularly and without consideration of the nature of carbohydrates or the source of proteins, are associated with an increased risk of cardiovascular disease (19). Moreover, severely restricting carbohydrate intake may result in untoward side effects like nausea, fatigue, and electrolyte loss. Therefore, the lower limit of carbohydrate consumption should not be less than 50 g a day (20).

The tolerable upper limit for protein consumption is 3.5 g per kg bodyweight per day for well-adapted subjects (21). According to research, bone, kidney, and liver disorders and increased risk of coronary artery disease and cancer are the adverse effects associated with the long-term consumption of a high-protein diet (22). Therefore, people on high-protein, low-carb diets should choose their source of protein very carefully. Many protein-rich foods of animal origin contain high levels of saturated fats and cholesterol. This may lead to a higher risk of heart disease, hyperlipidemiai  A medical term used to refer to an abnormally high level of lipids (fats) in the bloodstream, including cholesterol and triglycerides. , and hypercholesterolemiai  A medical term used to refer to the presence of abnormally high levels of cholesterol in the blood. (23).

Also, low-carbohydrate dietary patterns focused on animal-derived protein and fat sources were associated with higher mortality, whereas those that favored plant-derived protein were associated with lower mortality (24). Therefore, it is important to maintain a balance between these two sources of protein instead of only relying on animal meat for protein.

Some low-carbohydrate plant-derived protein sources include non-starchy vegetables, nuts, peanut butter, and whole-grain bread. Foods that are low in saturated fats and cholesterol include wheat gluten, textured vegetable protein, cottage cheese, Greek yogurt, egg, lentils, edamame, and split peas.

The high-protein, low-carb diet is a flexible approach to nutrition that can be tailored to individual preferences and needs. Since there is no one-size-fits-all formula, striking the right balance between these two macronutrients is key to achieving optimal health and fitness. From aiding weight loss and managing blood sugar levels to maintaining muscle mass, this diet can help improve your overall well-being. However, it should not be continued for a long period as it may cause heart disease and affect kidney function.

A low-carb, high-protein diet offers numerous benefits. It aids weight loss by reducing your appetite, stabilizing blood sugar levels, and promoting fat loss. However, including the right foods is the key to this diet. Foods high in protein may not always be low in carbs. Therefore, here is a list to help you out. Check out the infographic below to learn more about the foods to include and avoid in this diet.
