Methods: This was randomized controlled clinical trials design. The recruitment of research participants were officers of the Ramathibodi Hospital. All the participants were both male and female (73 participants), aged 25 – 50 years, and had BMI 23.0 – 39.9 kg per square meter. They were divided into two groups (normal and high protein group). In the first five months, all participants received the supplement with energy of 150 kilocalories; and the next 5 months the researcher introduced the meal suggestions. They were assessed the nutritional status (measured anthropometric, biochemical and dietary surveys).
Results: Forty three participants who completed the 10 months weight reduction were statistically significant difference between time at the same group (P<0.05). Body Mass Index (BMI), Body Fat Mass (BFM), Percent Body Fat (PBF) and Visceral Fat Area (VFA) dropped similarly to weight loss. There was no change in biochemical (P≥0.05) throughout the study period. However, HDL–Cholesterol increased overtime in both groups (P<0.05).
Conclusion: The ratio of the amount of protein intake had no effect on weight loss including the anthropometry assessment and biochemistry assessment.
