Is it easier to lose fat

According to a popular belief, weight loss is easier for some than for others. A research team demonstrated in the laboratory for the first time.

In light of the current debate on sport and its impact or not on the weight loss, it is important to note that the study in question has focused instead on the restriction of calories.

The researchers worked with obese women and 12 men at the Phoenix Epidemiology and Clinical Research Branch (PECRB), a division of the National Institutes of Health in the United States.

First of all, the metabolism of each participant was quantified using an indirect calorimeter, tool that collects air samples to estimate energy expenditure of a subject. These expenses are calculated based on an assessment of the quantity of consumed oxygen and produces carbon dioxide.

The researchers evaluated each participant using this tool after a day of fasting to determine their metabolic rate. They took into account the age, sex, race and weight of each database.

Then, for six weeks, the participants attended a regime which reduced by 50 percent the amount of calories consumed. Board at the PECRB, they had no possibility of cheating.

Those whose metabolism had declined during the day of young lost less weight during the regime of six weeks, which indicates that some had a metabolism faster than others.

“When obese individuals decrease their food intake, metabolic responses vary widely, and a more ‘efficient’ metabolism will eventually contribute to a weight loss training plan pdf “, says Dr. Susanne Votruba, co-author of the study and clinical researcher at the PECRB.

At this stage, however, researchers do not know if individuals are born with their metabolism or if the allure of it can evolve over the years.

“While behavioral factors such as adherence to a diet, affect the loss of weight to a certain extent, our study indicates that we should take into account a wider array, including the physiology of each”, continues Dr. Votruba.

The study has significant implications for the development of a personalized approach to weight loss, although further studies are needed to determine if these biological differences are innate, and to understand the best ways to combat a slow metabolism.

But for now the Dr. Martin Reinhardt, a post-doctoral fellow at the PECRB and lead author of the study, is optimistic.

“The findings reinforce the idea that some obese persons may need to make more efforts to lose weight, because of metabolic differences.” But biology is not destiny. A balanced diet and regular physical activity over time can be very effective in weight loss,”he notes that the venus factor reviews does it work

The study was published in the journal Diabetes.

Choose his regime to lose weight is not a guarantee of success


Is it better to have the choice of his regime if it is decided to lose weight? Not necessarily meet these American researchers who have conducted an experiment on the subject.


The most effective diet is before any one at which one stands scrupulously and perhaps not one chooses that.

Beginning at the reverse assumption that a chosen scheme is more easily applied and therefore doomed to success, a team of American researchers followed 207 participants, check phen375 buy online cheap australia mostly of rather elderly men with BMI equal to or greater than 30 kg/m2, for 48 weeks.

Half of the volunteers had the choice to follow a diet low carb or low fat, while the other group was assigned randomly to either of these two systems.

Among the free to choose Group, 58% of Guinea Pigs have opted for the low-carb diet then that 42% was his choice to low fat. Each participant enjoyed one-on-one by phone during the whole experience and was weighed at the end. Thus, researchers analyzed weight loss, respect, participation in monitoring of the regime, as well as lifestyle related to weight.

The results, published in the journal Annals of Internal Medicine from June 16, reveal that choose his regime does not help to lose weight, although the researchers noted an average loss of 5.7 kg (12.5 ponds) for participants of this group, while she was 6.7 kg (14.7 ponds) for the volunteers assigned to a diet. But statistically, no real difference measurement could not be registered.

“We have so-called unless participants themselves choose their diet, or with help, they would be more invested,” says Dr. William Yancy, one of the principal authors of this study. And added: “We also thought that a regime critical acclaim for its food preferences would be easier to follow, but this is not what we found”.

A plan chosen by taste may encourage them to eat more, according to Dr. Yancy, who also mentions the “personal trainer” effect. It is easier to join and follow a workout program if you the exercises to do, suggests researcher.

The future is certainly promised to regimes that would be fixed individually, the study concluded. The goal of weight loss could be more easily reached by associating with an individual a personality questionnaire, metabolic profiles including the level of cholesterol, insulin tests or even genetic profile of an individual.
