Energy requirements of Malaysian soldiers in a base camp.
The energy intake and expenditure of 20 healthy soldiers (mean age, 25 years, weight 61 kg and height 1.67 m) was assessed. Trained personnel stayed in the camp throughout the 5 weeks study period. Each soldier was subjected to a 7-day comprehensive protocol involving anthropometric, food intake, activity pattern and energy expenditure measurements. The mean change in body weight and fat content was minimal, -0.2kg and -0.25%, respectively. Body fat and BMI ranges from 10.0-21.6% and 19.8-24.9, respectively. The mean energy intake of 2190 ± 197 kcal was well below (81%) the recommended allowance of 2700 kcal for the Malaysian Armed Forces. The ration scale analysed chemically provides 2900 kcal thus suggesting a 24% wastage of daily ration. Contribution of protein (15%), fat (25%) and carbohydrate (60%) to energy intake appears to be in line to healthy dietary guidelines. Energy cost of standardised activities were found to be lower in Malaysian soldiers as compared to British soldiers studied under similar environment in the tropics. The mean total daily energy expenditure (TDEE) for soldiers were 2886 ± 222 kcal with a negative energy balance of about 700 kcal. The results suggested that there is a need to review the current provision with regard to food supply and preparation in army camps, to ensure that the menu provided are appealing as well as nutritious for the soldiers.
