Abstract

Objective: There is a need for alternative strategies to reduce childhood obesity and its health risks. The aim of this study was to investigate the effects of the Mediterranean diet and a low-fat diet on weight loss and some biochemical markers in obese adolescents after one year. Method: The study was conducted on 40 obese patients aged 13-18 years. Participants were randomly assigned to two different dietary programs, the Mediterranean diet and the low-fat diet, without energy restriction for one year. Anthropometric assessments and biochemical measurements (fasting blood glucose, insulin, uric acid, AST, ALT, total cholesterol, HDL cholesterol, LDL cholesterol, triglycerides) were performed at baseline and at the end of the first year. Findings: Body weight, BMI, neck, waist, hip and upper mid-arm circumference, fat percentage and fat mass decreased significantly in both diet groups. However, the waist-hip ratio decreased only in the Mediterranean diet group (p<0.05). Insulin, HOMA-IR, and total cholesterol levels decreased in both groups (p<0.05). In the Mediterranean diet group, HbA1c, triglyceride, and uric acid levels decreased significantly, while OUICKI levels increased significantly (p<0.05). Conclusion: Although both the Mediterranean diet and the low-fat diet showed beneficial effects on body weight, insulin resistance, and lipid profile in the long term without energy restriction, the Mediterranean diet was found to be superior to the low-fat diet in terms of insulin resistance

Özet

Amaç: Çocukluk çağı obezitesini ve sağlık risklerini azaltmak için alternatif stratejilere ihtiyaç vardır. Bu çalışmanın amacı, Akdeniz diyeti ve düşük yağlı diyetin, obez ergenlerde bir yıl sonra vücut ağırlığı kaybı ve bazı biyokimyasal belirteçler üzerindeki etkilerini araştırmaktır. Yöntem: Çalışma, 13-18 yaş arası 40 obez hasta üzerinde yapılmıştır. Katılımcılar, bir yıl boyunca enerji kısıtlaması olmaksızın Akdeniz diyeti ve düşük yağlı diyet olmak üzere iki farklı diyet programına rastgele atanmıştır. Antropometrik değerlendirmeler ve biyokimyasal ölçümler (açlık kan şekeri, insülin, ürik asit, AST, ALT, toplam kolesterol, HDL kolesterol, LDL kolesterol, trigliseritler) başlangıçta ve birinci yılın sonunda yapılmıştır. Bulgular: Vücut ağırlığı, BMI, boyun, bel, kalça ve üst orta kol çevresi, yağ yüzdesi ve yağ kütlesi her iki diyet grubunda da anlamlı derecede azalmıştır. Bununla birlikte, bel-kalça oranı sadece Akdeniz diyeti grubunda azalmıştır (p<0,05). Her iki grupta da insülin, HOMA-IR ve toplam kolesterol düzeyleri azalmıştır (p<0,05). Akdeniz diyeti grubunda HbA1c, trigliserit ve ürik asit düzeyleri anlamlı derecede azalırken, OUICKI düzeyleri anlamlı derecede artmıştır (p<0,05). Sonuç: Hem Akdeniz diyeti hem de düşük yağlı diyet, enerji kısıtlaması olmaksızın uzun dönemde vücut ağırlığı, insülin direnci ve lipid profili üzerinde faydalı etkiler gösterse de, insülin direnci açısından Akdeniz diyetinin düşük yağlı diyete göre daha üstün olduğu bulunmuştur.
