It’s easy to lose weight fast, but it’s not the healthiest way. You can get away with a rapid weight loss plan if you just need to drop 5 kilos or 10 pounds for a special event. The chances are that if you worked at it you could even keep it off.
For those who carry a lot more than that in excess weight, fast weight loss is not a sustainable way to lose weight over the long term. By doing it regularly you can do unseen damage to your body.
It is far better to go the slow and steady route to permanent weight loss.
