There are a lot of very overweight people struggling at my gym and I am increasingly worried about predictions that 50 per cent of our children will be overweight or obese adults by 2030. Everything I have read recently suggests that exercise as a means of losing weight has been greatly exaggerated and that putting the emphasis on exercise means that we are unlikely to tackle obesity in our children.
It's difficult to believe that:
- 15 minutes lifting weights equals the 100 calories in one small cappuccino;
- 75 minutes of stretching equals the 220 calories in a small mars bar;
- 15 minutes on the stairclimber equals the 129 calories in a can of coke;
- 30 minutes running on the treadmill at 10kmph equals the 400 calories in one blueberry muffin;
- 50 minutes on indoor rower equals the 450 calories in a large slice of cheesecake;
- 19 minutes on elliptical trainer equals the 95 calories in a medium size banana;
- 30 minutes of aerobics equals the 163 calories in a small pack of raisins;
- 10 minutes on the exercise bike equals the 55 calories in a low-fat fruit yoghurt.
