Some suggest that people on a diet are healthier than those not on a diet because they are less likely to suffer from heart disease, obesity, and diabetes. However, others have argued that those on a diet are healthier, not because they are on a diet, but because they are more likely to exercise than those on no diet at all. Studies controlling for exercise found that diet alone did not have a significant effect on rates of heart disease, obesity, and diabetes.
True / False: The effectiveness of a diet in reducing heart disease, obesity, and diabetes depends on whether exercise is included as part of the regimen.
