Too much body fat and not enough muscle means your RMR is slower than it need be. It is possible to measure your body fat percentage, and many types of scales now do this for you using a technique called ‘bioelectrical impedence’. (Don’t worry – it doesn’t hurt!) A healthy range of body fat for adult women is between 24 and 34 per cent; for men it is 18 to 26 per cent. The lower you can get it, the higher your RMR should go. But beware: if a trainer in a gym asks if he or she can measure your body fat, they may employ a much more embarrassing method, involving the use of callipers to pinch the excess flab in your waist, thighs, hips and upper arms. This can be especially galling given that most trainers are god-like creatures with perfect abs, and you’d be perfectly entitled to run a mile from this ritual humiliation.
