The Role of Nutrition and Exercise in Losing Weight

The first reason that impact on losing weight is the nutrition. Nutrition plays an important role in determining our weight. The nutrient in one meal, the number of meals per day, and the moderation in eating are the three main factors that will have a big effect on our body. Therefore, firstly, we need to know what exactly is a balanced meal. Rohrlach (2017) indicates that: “A balanced meal is a snapshot of a diet that covers the three core food groups. As seen on this portion plate, the balance is a quarter proteins, a quarter carbohydrates, and half vegetables.” Rohrlach (2017) further explains that: “One quarter carbohydrate food for energy.
