Protein Diet: An Effective Way to Reduce Body Weight
A protein diet, also known as a high-protein diet, is one of the most commonly chosen methods for rapid weight loss. It is based on increased protein intake while limiting carbohydrates and fats. Supported by solid scientific literature, this diet has gained popularity among both athletes and individuals aiming to lose weight.

Scientific Foundations of the Protein Diet
The role of protein in the body
Protein plays a key role in tissue building and regeneration, enzyme and hormone production. A high-protein diet may support weight loss through:
- Increased satiety — proteins influence the secretion of satiety hormones (e.g. GLP-1, cholecystokinin) and reduce the level of the hunger hormone ghrelin (Leidy HJ et al., 2015).
- Increased thermogenesis — protein digestion requires more energy compared to fats and carbohydrates (Paddon-Jones D et al., 2008).
- Protection of muscle mass — during calorie restriction, high protein intake minimizes the loss of lean body mass (Phillips SM, 2014).
Effectiveness of the protein diet in weight reduction
Meta-analyses of clinical trials indicate that high-protein diets lead to significantly greater weight loss and improved body composition compared to standard diets (Wycherley TP et al., 2012).
Principles of the Protein Diet
Diet phases
The protein diet usually consists of several phases:
- Intensive reduction phase — very low carbohydrate intake, high protein intake.
- Transition phase — gradual introduction of healthier carbohydrates (e.g. vegetables and fruits with a low glycemic index).
- Stabilization phase — a balanced diet with a predominance of protein.
Allowed products
The protein diet is primarily based on:
- Lean meat (chicken, turkey, beef)
- Fish and seafood
- Eggs
- Low-fat dairy products
- Legumes (in moderate amounts)
- Low-starch vegetables
The Role of Ketosis in the Protein Diet
During the intensive reduction phase, when carbohydrate intake is very low, the body may enter a state of ketosis. At this point, the body begins to burn fat as its primary energy source, producing ketones. Ketosis may accelerate fat burning and help reduce hunger. It is a natural and desirable effect in a high-protein diet, but it requires appropriate health monitoring.
The Dukan Diet
One of the most well-known protein diet models is the Dukan diet, developed by French doctor Pierre Dukan. It consists of four phases: the attack phase (proteins only), the alternating phase (proteins + vegetables), the consolidation phase, and the stabilization phase. The Dukan diet emphasizes high protein intake, minimizing fats and carbohydrates, and gradually reintroducing other food groups. Although this diet may deliver quick results, it is controversial among specialists due to potential nutrient deficiencies and excessive kidney strain, therefore it should be followed under strict professional supervision.
Potential Benefits
- Weight loss
- Improved lipid profile (reduction of LDL and triglycerides)
- Stabilization of blood sugar levels
- Increased muscle mass during strength training
Potential Risks
Although a protein diet is safe for most healthy adults, its long-term use may involve certain risks:
- Kidney strain — especially in individuals with existing kidney disease.
- Risk of deficiencies — limiting vegetables and fruits may lead to vitamin and mineral deficiencies.
- Digestive issues — e.g. constipation due to low fiber intake.
Therefore, it is recommended to consult a physician or dietitian before starting the diet.
