Dieting slows down your body`s metabolism
Losing weight is twice as hard as you may think as reducing your calorie intake slows down your metabolism, say scientists.
They said that dieters` expectations have been too high, and official guidance that cutting 500 calories a day will result in a pound of weight being lost a week is plain wrong, the Daily Mail reported.
But dieters need not worry, as the same experts have created an online calculator that allows would-be slimmers to adjust their expectations and gain a more realistic picture of what they can expect to achieve.
The Body Weight Simulator website – at bwsimulator.niddk.nih.gov – estimates how much less that person will have to eat, or how much more exercise they`ll have to do reach their goal.
Official advice in the UK and the U.S. has long been that cutting out 500 calories a day will lead to weight loss of a pound a week.
But the calculation assumes that weight loss is steady and does not take into account that a person`s metabolism slows down as they lose weight, making subsequent pounds harder to shed.
