The National Health Forum has announced that they believe 80 percent of British men will be clinically overweight or obese by 2020. Not only that but the level of diabetes, strokes and heart disease will also increase as men get heavier and fatter.

The study, led by Professor Kim McPherson, Oxford University, is an update of Foresight Report and uses figures from 1993 to 2007 to predict obesity levels in the future.

By 2020 some 41 percent of men aged between 20 and 65 years old will be obese and a further 40 percent will be classed as overweight. The figure is less high, yet no less alarming as by 2020, 62 percent of women will either by overweight or obese.

The study also predicts that by the year 2050 they will be a rise in obesity-related strokes (23 percent), obesity-related high blood pressure (34 percent), a rise in obesity-related coronary heart disease (44 percent) and a massive 98 percent increase in obesity-related diabetes.

But the National Health Forum suggest that you can prevent becoming a statistic by re-addressing your diet and substituting energy dense foods for more healthy foods, coupled with regular exercise.
