How to lose the calories during eating?

-9lX_aA8YZMSpring can bring real problems to those who tries to abide diet. How can you say “no” to one or several donuts when the weather grows colder?
Spring can be a confusing time for the body-conscious – a time when thoughts drift towards summer on the beach, but chilly temperatures have many reaching for an extra biscuit.
For those who tries to lose several pounds without severe diets exists only one way: food which burns calories during eating. But is it possible – to find those type of food?
“A negative-calorie food would by definition consume more calories, for the body to handle it and process it, than is contained in the nutrient content in the food.
“It’s great idea but only theoretically,” says Tim Garvey, chair of the department of nutrition sciences at the University of Alabama, Birmingham.
“In actuality there are no negative-calorie foods,” he says.
Or, as the esteemed nutritionist Marion Nestle put it in a one-line email to the BBC: “It’s just a myth. Those food doesn’t exist.”
Consider celery, often proposed as a negative-calorie food due to its low-calorie count, high water density, and impressive fibre content.
While all that chewing and digesting of the fibrous food does burn calories, it doesn’t burn a lot. ”
There may be just ten calories in a larger stick, but the body takes only 1/5 that much,” to process, says Dr Garvey. “It still adds the calories.”
Never mind that man cannot live on celery alone, and few people just eat raw celery.
“It’s more of a gateway to cream cheese or peanut butter,” says David Grotto, a nutritionist and author of The Best Things You Can Eat.
That’s not to say that celery sticks – along with other high fibre, water-heavy fruits and vegetables – have no value as weight-loss aids.
“This food gives you a feeling of the full-filled stomach and increase satiety,” says Dr Garvey, keeping you from eating more calories later – but not burning off the calories you’ve already consumed.
But there are other things you can eat or drink that are supposed to work in a different way, by making metabolic changes in the body.
One is cold water, which the body has to warm up to 37C. But Grotto is not particularly impressed.
“There’s no research to say that cold water drinkers burn more calories,” he says.
“Any amount of metabolic hit is not a significant amount – not more than five calories.”
Other foods have different ways of increasing the metabolic rate. Caffeine, guanine, taurine and green tea extracts all have these properties, says Ron Mendel, who has done research on diet drinks that combine these ingredients.
In a study with only twenty participants, he found that those who consumed a diet drink called Celsius, which debuted in 2005, burned more calories than when they drank diet cola.
“The big picture here is, this is certainly not adding up to hundreds of calories a day by any stretch,” says Mendel, the programme director for exercise science at Mount Union University in Alliance, Ohio.
Still, he speculates the small gains could result in a loss of ten lb over a year.
That’s why it’s clear that the change in metabolism could lead to significant weight loss.
As a doctor focused on obesity and nutrition, Dr Garvey maintains that the only real way to lose weight is the boring, old-fashioned, unsatisfying and ultimately successful method: eat fewer calories than you burn through exercise – not digestion.
