Many people engage themselves in buying and snacking of low nutritional value foods (Foreyt, 2010). It is therefore of significance to maintain a gentle awareness of food choices.

It is important to acquire knowledge of the benefits that come with regular physical exercise.

As observed by Goldstein, exercise has many health benefits such as maintenance of basal metabolic rate, increased physical activity, effect on food intake and appetite as well as enhanced psychological effects. Obesity shows many of the health consequences of inactivity and the benefits of physical exercise are immense (Goldstein, 1999). Regular non-strenuous physical exercise is an important means of preventing the disease in people of all ages. It is evidenced that obesity is related more to inactivity or less activity than ingestion.
