4. Being a Bit Overweight.

If you worry that being even a few kilograms over your target is a death sentence, fret not. A US study of the mortality rates of 2.3 million people found that those with a Body Mass Index ( BMI ) of 25 to 30 - technically " overweight" - were not more likely to die of cardiovascular disease and cancer than those with a "healthy" BMI of 18.5 to 25.
How come? It's possible, says Katherine Flegal, senior research sceintist study, that older who are overweight have greater nutritional reserves thst help carry them through bouts of ill health - this may influence that overall figures for all age groups. But Dr cloin Waine, chair of the National Obesity Forum in the UK,also point out that where are put on weight can be more significant than your BMI :
carrying weight round your middle is much worse than carrying it on your hips.
"Having a waist of over 37 inches for men and 33 inches for women, gives you a significantly greater risk of cardiovascular disease and Types 2 diabetes," he says. "That danger rises even more sleeply above 40 inches [for men and] 37 inches [for women].
" So if you are generally fit and active, then carrying a few extra pounds is not worth stressing over.

Health risks climb far more sleeply if you're clinically obsense (BMI 30 and above). A study that followes 115,000 nurses for 15 years showed the obese women had a 28 times higher risk of developing diabetes than women with a BMI of 22. Dr Waine advises keeping your BMI no higher than 27 (devide your weight in kilos by your height in metres squared).
