dietary energy intake and body composition in a student population.

In a 2015 health and fitness research involving 2208 study participants with a mean age of 49 years, the researchers found an inverse association between the level of physical activity and the body fat percentage (Hassapidou 2015). Also, the research also concluded that the observed association between the body fat percentage and the dietary intake varied between the young and the old members of the population. These results are consistent with the conclusions of this study. First, the body fat percentage of individual participants even with a similar dietary intake but different level of activity was entirely different. Secondly, a number of calories consumed by each of the participants contributed directly to their body composition. However, there were differences in the resultant body composition indicator for those taking more fats or more proteins in their diets.

In an earlier study, the macronutrients composition of individuals’ diet determines the body composition outcomes of the individual. In a population where the most abundant diet comprises of more fats than proteins or natural carbohydrates, there is a high likelihood of people developing high body fat content (Parsons 2013). The results of this study, therefore, agree with the previous study. However, research focused on different age-groups and genders is required to provide more insight into the topic (Clauss 2012).

The significance of these results is that they add to the existing body of knowledge on diet and body composition. The prevailing understanding is that daily intake determines the body fat content that is retained (Vasilaras 2012). However, deeper understanding has it that when energy is consumed, it must have a mode of exit from the body otherwise; it will be stored up in the day’s tissues as fat (Bishop & Hill 2015). The implication of this is that with a higher energy consumption and even higher energy usage per day, say for athletes and other active occupations, the body fat content may be even less than that of a person with half the dietary intake but living a sedentary lifestyle. This is also supported by other studies (Robinson & Christiansen 2014.

Research Limitations

One of the limitations of this research is that it has not differentiated the body composition indicators of both male and female participants and those of different age-groups. This is likely to affect the specific conclusions. However, the analysis of the data presented has not based any argument on the same and has recognized the differences in the energy requirements and the overall body composition indicators. The research is, however, generalized rather than focused on a specific cohort. Future researches should at least focus on a specific group of people differentiated either by age or gender.

The Implications of the Research

This research can be used in determining the energy and activity level requirements. The implications of the research are that dieticians must observe and consider various factors including dietary intake, age, gender, physical activity in structuring and describing dietary plans for clients (Assmann et al. 2013).
