YÜKSEK PROTEİNLİ DİYETLERİN METABOLİZMA ÜZERİNE ETKİSİ

Protein, karbonhidrat veya yağdan daha doyurucu olan yüksek proteinli diyetler (enerjinin% 25 - % 35'ü) ağırlık kaybı için sıklıkla kullanılmaktadır. Yüksek proteinli diyetler de genellikle karbonhidrat protein ile yer değiştirir ve doymuş yağda düşük veya yüksek olabilir. Her ne kadar karbonhidrat alımı azaldıkça serum trigliserid daha düşük olsa dahi yüksek yoğunluklu lipoprotein kolesterolü ve düşük yoğunluklu lipoprotein kolesterolü üzerindeki etkiler, karbonhidrat kısıtlamasına ve doymuş yağ alımına güçlü bir şekilde bağlıdır ve bazı durumlarda, kilo kaybına rağmen yoğunluk lipoprotein kolesterolü yükselebilmektedir.Bu bulgulardan hareketle konunun uzmanları, kilo kaybı üzerine yüksek proteinli diyetlerin etkilerini araştırmaya başlamış yapılan çalışmalarda ise aşırı kilolu diyet proteini yüzdesini yükseltmeyi savunmuştur. Bu savunmanın gerçekliği hakkında makro besleyici durumun, vücut ağırlığı üzerindeki etkisi açısından yeterince kapsamlı ve uzun vadeli çalışmalar yapılamamıştır.Bu çalışmada literatürde mevcut bulgular incelenecek ve ileride daha kapsamlı çalışmalara yol göstermesi hedeflenmektedir.

EFFECTS OF HİGH-PROTEİN DİETS ON METABOLİSM

High protein diets (25% - 35% of energy) that are more satisfying than protein, carbohydrate or fat are often used for weight loss. High protein diets are often replaced by carbohydrate protein and may be low or high in saturated fat. The effects on high-density lipoprotein cholesterol and low-density lipoprotein cholesterol are strongly dependent on carbohydrate restriction and saturated fat intake, even though serum triglyceride is lower as carbohydrate intake decreases, and in some cases, density lipoprotein cholesterol may rise despite weight loss. From these findings, experts argue that to increase the percentage of overweight dietary protein in studies that have begun to investigate the effects of high protein diets on weight loss. This argument has not been sufficiently comprehensive and long-term studies on the reality of macro-nutritional status, its impact on body weight. In this study, the findings in the literature will be investigated and in the future it is aimed to reach a more comprehensive study.
