Energy nutrients intake in overweight and normal-weight young men

Objective To explore the characteristics of energy nutrients intake in overweight young men.Methods Eighty-two young men aged 19-28 years were divided into overweight group(n=42) and normal-weight group(n=40) based on their body mass index(BMI)(BMI≥25.0 kg/cm2 for overweight and BMI≥18.5 kg/cm2 and ≤23.9 kg/cm2 for normal weight).The dietary intake was assessed with 24-hour recall method in a successive 3-day.Anthropometric parameters such as height,weight,waist circumference,hip circumference,body fat,and blood pressure were measured.Fasting blood glucose,triglyceride(TG),total cholesterol(TC),high-density lipoprotein cholesterol(HDL-C),low-density lipoprotein cholesterol(LDL-C) and,non-esterified fatty acid(NEFA) in serum were also detected.Results Compared with the normal-weight,the overweight had a nonsignificantly higher total energy intake(P0.05),but a higher animal food consumption(28.12±8.08%) and fat intake(29.83±5.81%),especially for animal fat(44.76±15.80% higher than that of the normal-weight)(P0.05).There were significant differences in serum lipids between the two groups(P0.05 for all).Thereinto the overweight had higher LDL-C(2.62±0.63 mmol/L),TG(1.37±0.98 mmol/L),TC(4.72±0.85 mmol/L),and NEFA(693.33±219.97 mmol/L) than those of the normal-weight(2.14±0.59 mmol/L,0.94±0.39 mmol/L,4.27±0.83 mmol/L,and 493.68±189.30 μmol/L),but lower HDL-C.Conclusion The intake of dietary fat,especially animal fat,in overweight men should be adjusted for the improvement of obesity to prevent related metabolite diseases.
