No, because although you get rid of a few kilos quickly with renunciation and willpower, this does not mean that you have lost body fat exclusively and that is the goal. The scientific evidence is also clear: the chances of success in keeping your new weight permanently are vanishingly small. Instead, many people find themselves in a frustrating, year-long cycle of gaining and losing weight. If, on the other hand, you start from the beginning with a gradual change in diet and a long-term perspective, in retrospect you will reach your goal much faster.
