Your friend matthew is a very busy guy who is becoming concerned with his weight and health. because he is so busy, he often stops to grab a fast-food dinner. when you tell him that fast-food meals are not conducive to losing weight, he replies that "it's just this one burger." what advice would you give him?

One of the biggest reasons why people struggle to lose weight is lack of discipline. Even one occasional burger can have a significant impact because it breaks the habit of healthy eating. If this is a behaviour that he shows often, it is not conducive to his goal of being healthy.

A good solution would be to find alternatives that he could prepare easily and would not take him a lot of time. Alternatively, he could still eat out but try to find something that is more balanced and nutritional.
