London: For anyone struggling with excess weight and type 2 diabetes, this low-carb plan part of the Mail’s Good Health for Life series could be life-transforming. Here, Dr. David Unwin the NHS GP behind it explains how the plan works, while chef and food writer Katie Caldesi gives low-carb recipes, written exclusively for you, that take less than 30 minutes to prepare.
When I started as a GP in 1986, my practice had just 57 people with type 2 diabetes; 34 years later, with roughly the same number of people at the surgery, there are now 472 that’s an eight-fold increase. Alongside this, I have seen an epidemic of obesity. Of course, my practice in Southport, Merseyside, is hardly unique, with the global explosion in obesity and type 2 puzzling health experts worldwide. In the UK, nearly one in three people today are overweight or obese.
So what is going on? This cannot be genetic — people’s genes cannot change in just 35 years. It’s something about our environment that has changed. It’s our diet. We’re told the fundamental cause of obesity is an imbalance between calories consumed and calories expended.
However, while the health benefits of exercise are generally agreed on, doctors increasingly suspect that losing weight is not one of them. A major review published by The American Dietetic Association in 2007 concluded that exercise alone leads to minimal weight loss. Why is this?
The first problem is the length of time it takes to ‘exercise off’ the food you probably should not have eaten. For example, burning off a 300-calorie hamburger would take about 75 minutes of walking. It’s also possible that exercise makes some people hungrier, so calorie burning could be canceled out, or worse, by what they then eat.
