Studies have shown that poor eating habits and sedentary life-styles are detrimental to the health of both men and women. These lead to heart disease, strokes and high blood pressure. This study aimed to investigate the effects of weight loss and improved health. The objectives of the study were to show how a healthy life-style, eating correctly and exercising regularly contributed to weight loss. Both the qualitative and quantitative method of analysis was adopted. The study was piloted with ten customers from a well-known gymnasium who attended classes with a specific fitness instructor and dietician for one week. The results showed that a healthy life-style helped customers to lose weight and consequently made them feel better. The study was then conducted with thirty customers from the same gymnasium; however, two fitness instructors and dieticians were used. The results showed weight loss was not dependant on the fitness instructor or dietician but was directly related to the exercise regime, the food consumed and the life-style of the customer. It also showed that exercising and eating healthy foods made the customers feel better. This study concluded that healthy eating, regular exercising and a healthy life-style promoted weight loss. It is recommended that more customers, especially those who are over-weight in the gymnasium be introduced to this combination for weight loss.
