It is important to be realistic about how much weight you want to lose and over how much time. If you lose weight gradually, you’re more likely to reach and stay at a healthy weight.
Most people put on weight over several months or longer, so the time to reach your target weight should be roughly the same.
To monitor your weight loss, weigh yourself weekly at the same time of day and using the same scales. If you find it difficult to get to your target, or if you reach it very easily, talk to your doctor, nurse or dietitian about setting a new one.
