Effect of Protein Supplement on Weight Loss in Overweight and Obese Adults

Abstract

Background: Overweight and obesity are two major public health problems that affect health of people both short term and long term. Controlling energy from diet and modification ratio of nutrient intake are alternative choices for reducing weight. This study aimed to compare high and normal protein diet intake which results in changing the anthropometric assessment and biochemical assessment of the body.

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.
