Answer: A healthy diet consists of healthy food groups. When someone has a healthy diet, they eat meals with healthier options rather than unhealthy meals like junk food. Dieting to lose weight does include healthy foods, but the main goal is to lose weight as well as being healthy. Someone who is dieting to lose weight may keep track of calorie intake and follow recommended serving sizes. In conclusion healthy diets are mainly for being healthier and dieting to lose weight is more for losing weight.
