What is healthy weight loss? It's natural for anyone trying to lose weight to want to lose it very quickly.

It's about an ongoing lifestyle that includes long-term changes in daily eating and exercise habits.

This easy-to-use weight loss calorie goal calculator can help you assess your caloric needs.
