Prefer to lose weight slowly and less The most important thing in losing weight is to choose a lifestyle that can be sustained for life. So no longer follow one strict strict diet after another with the accompanying yo-yo effect. This may make the weight loss faster in the first instance and you will also lose the most kilos. But those pounds are just as hard again if you, almost inevitably, no longer maintain this diet. It is better to slow down and lose less weight altogether, but permanently.
