Just three minutes of intense exercise can help burn fat
London: Those who feel lazy to go to gym or do not have time to exercise may be literally jumping once they read this news. Scientists say we donalt39t need to work for hours
at the gym to cut flab, as just three minutes of exercise a week could be enough to help you lose weight. The secret is short bursts of intense exercise – known as high- intensity interval training.
According Scientists at Birmingham and Nottingham universities, such a session once a week is far more effective at – burning fat than daily workouts, the Daily Express reported. HIT triggers the release of fatburning hormones helping to shift those unwanted love handles. It also moves glucose from the blood into muscle tissue where it is burned as energy rather than converted to fat. And vigorous bursts of physical activity also have the effect of killing your appetite, whereas longer workouts can leave you wanting to eat more. This means people keen to lose weight would be less likely to be tempted to snack on unhealthy treats if they ditched the gym and went for a short brisk walk.
HIT sessions can include running, riding a bike or walking. ” HIT is really good at improving glucose uptake into the muscles in a very, very short time,” Professor James Timmons, leading the research at Birmingham, said. ” With really intense exercise, you release hormones that can help break down fat. This may help burn that fat over time, after HIT is done. Also, we think, but donalt39t know, that HIT will subdue appetite, while traditional exercise will stimulate appetite. This last point is key and will be researched by our team,” he stated.
Dieting slows down bodys metabolism
London: Losing weight is twice as hard as you may think as reducing your calorie intake slows down your metabolism, say scientists. They said that dietersalt39 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 theyalt39ll 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 persons metabolism slows down as they lose weight, making subsequent pounds harder to shed.
This means weight is twice as hard to shift, the researchers said at the American Association for the Advancement of Sciences annual conference. The old system says that cutting 100 calories a day will lead to the loss of 10lb a year. The revised rule predicts just 5lb will be shifted. Rather than expecting too much, dieters should be patient, said Boyd Swinburn, an obesity expert from Deakin University in Melbourne, Australia.
Advising slimmers not to set their sights on more than a half a pound of weight loss a week, he said: ” This is extremely good. This is a marathon not a sprint.” — AGENCIES
