Slimfast Case Study
Natalie Stein, an assistant professor with the Program for Public Health at Michigan State University, says that by replacing certain meals with shakes and other designated replacement snacks, users of the SlimFast products are limiting their consumption of foods containing important nutrients. In fact, the SlimFast diet does not even meet the dietary guidelines, laid out by the United States Department of Agriculture (Stein, 2015).
The human body can only produce twelve of the twenty amino acids. This means that the other eight must be consumed through a healthy and balanced diet. The SlimFast diet may provide the necessary amount of vitamins and minerals, but does not meet the recommended amounts of fruits, vegetables, whole grains, and dairy. Stein goes on to say that these foods may reduce the risk of certain diseases such as cardiovascular disease and diabetes.

The SlimFast diet, like most diets, recommends at least some physical exercise in addition to dieting. This means the SlimFast diet plan provides under half the recommended calories for a moderately active person and well under half the recommended calories for an active person. This undernutrition can lead to the breaking down of muscles for the body to use as fuel. The loss of muscle weight could appear to dieters to be an accomplishment, but it is actually just the degradation of their body. Aside from posing some health risks due to the lack of dietary diversity, the SlimFast diet also provide little to no advantage for long term weight loss. In a study comparing low-carbohydrate diets and low-fat/low-calorie diets, it was actually found that while the low-calorie diets provided more significant weight loss after six months than low-carbohydrate diets, the difference in weight loss was much less
