They say that no matter how hard or easy it is to lose weight, the real test is keeping it off for good. For long-term weight loss, you will need to establish new habits compared to the ones that caused weight gain in the first place, and for optimal health, it is best to select nutritious foods most of the time. 

Weight loss is hard. It is hard to find anyone who will dispute that! Even harder than losing weight can be losing it long-term. It is more common to stop losing weight, or to regain the weight, than to keep losing weight.
