In fact, there is no standard answer to this question, which varies from person to person, but if you want to lose weight quickly, you usually won't. I posted a post in the Post Bar about how I lost weight in partial weight loss, that is, how my waist and legs lost weight. I use an imported plastic belt from Japan and VIGGIE GREEN from South Korea. These have obvious effects. You should see the effect in two weeks, so I don't know if your requirements are high or not.
