No, without a proper nutrition, your body won't receive the nutrients and vitamins that helps it stay fit and eventually lose weight. For example, if your were out and worked out for 1 hour cardio, you would lose a couple pounds. But, if then you went home and ate a greasy burger or microwaved meal, you pretty much gain all of the weight back and probably even more. However, if you ate a healthy and nutritious lunch, it would probably give you more energy, improve your diet, and sustain your metabolism. To lose weight in a healthy way, there must be a balance in your diet and physical activity.
