Diets after Holidays

How many of you have been starting a diet after this holiday season? The Flavor Point Diet, the Longevity Diet, the Cheaters Diet ... The variety of diets is amazing nowadays. But do you really think that they really work. Most probably, they have an effect but only a short-term one, I believe. Once I had tried a cabbage diet and was surprised by the result. I had lost 3 kg for two weeks. As soon as I finished the diet, 3 kg was mine again. Only regular sport and, such called, eutrophy are effective for your body and health.
