Overweight and obesity are risk factors for many chronic diseases. Health problems such as insulin resistance, glucose intolerance, hypertension, coronary heart disease, stroke, respiratory problems, cancer, obesity, etc. are the first to come to mind.
There is no general idea about what a high-protein diet is. In the food industry, total energy comes from protein. This term is used when the incoming rate is more than 20%. In high protein diets in body weight loss studies, this ratio aims to constitute approximately 30% of the energy. Generally, the protein percentage is increased from 15 to 30. In such slimming diets, the amount of protein taken with the diet does not increase by 2 times since the total energy amount of the diet is reduced. Ketone bodies are formed on low-carb diets when carbohydrate intake is <20g/day. During fasting, fats are burned instead of carbohydrates, causing an increase in ketone bodies in the blood, a decrease in the pH of the blood, and loss of consciousness. It is stated that high protein-low carbohydrate diets are not superior to high protein-medium carbohydrate diets in terms of appetite control. A weight loss of 1 kg per week was observed in individuals fed a high-protein diet for 4 weeks. Positive improvements are seen in health indicators. The reduced lean mass in body fat mass was preserved. High protein diets show better fat loss with reduced carbohydrate amounts, but these have been observed to be short-term. According to the studies, in the meta-analysis, the highest weight loss with the high protein diet was 3.7 kg in the six-month study, while it was 1.2 kg in the 17-month study. The average weight loss from eight studies was 6.3 kg on the high-protein diet and 5 kg on the standard diet. It is more reliable to lose weight with a balanced diet, rather than diets that cause rapid weight loss but whose long-term possible risks are not clearly explained.
It is stated that the long-term cardiovascular damages outweigh the short-term benefits of weight loss. It has been found that the risk of cardiovascular disease increases by 5% with a 20 g decrease in carbohydrates and a 5 g increase in protein.
With a low carbohydrate-high protein diet. Since fruit consumption is reduced in the diet, it has negative effects on antioxidants. It provides longer-term satiety than hydrates and fats. There are ongoing concerns about the kidney health of high protein-low carbohydrate diets, but little is known about the effects of such diets on the kidneys.
