it depends on where the weight loss is coming from. the loss of water weight usually doesn t come with a change in the physique unless the person is only 10-15 lbs overweight. normally the first 7-10 days on a diet 90% of the weight lost is water weight as stored nutrients are metabolized in the body. for most it takes a good 3-4 weeks before there is measurable fat loss through body fat analysis. so it can be a good 2 months before you really see a change in those problem areas of excess fat, etc. you should get your body fat analyzed so you know exactly where losses on the scale are occurring, it s one of the biggest mistakes that most people make. when you lose weight on the scale it s always a combination of water, muscle and fat. how the weight is lost and at what rate will determine how much of each is lost. monitoring your body fat tells you exactly that instead of guessing.
