A weight loss of just 5 to 10% reduces the risk of type 2 diabetes by more than half and brings nearly half of people with existing diabetes into remission. Analyses of randomized trials also show a reduction in premature mortality of approximately 15%. The approach must be sustainable, because temporary weight loss yields fewer benefits than lasting behavioral change.
Even losing 5 to 10% of your body weight has a measurable effect: the risk of type 2 diabetes drops by more than half, and if you already have diabetes, nearly half of the people who lose a significant amount of weight go into full remission. An analysis of multiple randomised trials also shows that the risk of dying prematurely falls by around 15%. These are not small numbers.
The most honest thing you need to know is this: in the large studies, weight loss was always part of a package -- eating more healthily combined with moving more. Weight itself is the core, but the way you go about it forms part of the outcome. A crash diet you stick to for three months counts for less than an approach you can still sustain a year later. That may sound obvious, but it is precisely where the gain or the loss lies.
If you find that you cannot manage on your own, that is not a failure but a biological reality: your body actively works against weight loss. Medication or, in certain cases, surgery are not a last resort but recognised options with good results. Your GP or an internist can tell you what is realistically achievable for you and what is available.
