6 Myths Busted about boosting your metabolism




There are many myths and misconceptions when it comes to boosting your metabolism. Here are six of the most common ones, debunked.


Myth #1 - Muscle burns more calories than fat


Although technically true, the difference is negligible. You'll roughly burn 4-8kcals more per pound of muscle than per pound of fat per day. So if you put on 2lbs of muscle which isn't easy, you could burn an extra 20kcals per day...... That's less than a carrot.


Myth #2: Eating more often speeds up your metabolism


Thermic Effect of Feeding (TEF) is the energy needed to digest and absorb food. So more meals would mean higher TEF? No.


If calories are kept constant, your TEF will be the pretty much the same whether you need to digest 2000 calories from 2, 3, 4 or 7 meals per day.


Find a meal pattern than suits you and your schedule.


Myth #3 - Foods that speed up your metabolism


Foods like green tea, caffeine, ginger chili may provide a TEENY boost in your metabolism, but not enough to make any difference to your weight. You're talking an extra 50kcals - 1/4 of a biscuit.


Myth #4 - Exercise increases your RMR


Exercise like HIT training can increase calorie expenditure (1) after your workout, however only if you're NOT in a calorie deficit (2).


In fact, in untrained people, an increase in exercise can actually suppress their metabolic rate (shocking I know!) (2).


However, a big however. From experience (over 300 RMR tests now!), fitter people definitely do seem to burn far higher calories at rest compared to inactive individuals. This also seems to correlate with people who eat a lot.


So get fit and eat a lot!!


Myth #5: Sleep boosts your metabolism


Although it does have some favourable effects on body composition, this is not down to a boost in your metabolism. Sleep deprivation just means you're tired the next day so you move less and hunger hormone imbalances mean you eat more.


Myth #6: Your metabolism isn't slowing down with your age.


Another big recent study (4) showed how your metabolic rate plateaus from age 20 to 60. and then only declines by around 1% per year thereafter.


So don't blame your age, blame your lifestyle......
