BEST DIET : LOSE WEIGHT WITH BEST TRICK

If cannabis causes the snack foods, how is it possible that pot smokers are thinner than nonsmokers?

a new study published in the American Journal of Epidemiology is an interesting connection between marijuana use and body weight, indicating that rates obesity are lower by about a third in people who smoke pot at least three times a week, compared to those who use marijuana at all.

The researchers analyzed data from two large national surveys of the US population, which together included some 52,000 participants. In the first survey, they found that 22% of those who do not smoke marijuana were obese, compared to only 14% of regular smokers of marijuana. The second survey found that 25% of non-smokers were obese, compared to 17% of regular users of cannabis.

The association between smoking pot and the lowest risk of obesity remained strong even after adjusting for other factors that might affect body fat and health, such as smoking , age and sex. But the correlation between the weeds and the weight does not mean that marijuana actually causes weight loss.

PLUS Cheers, ladies! A drink a day can mean a healthy old age

Many other factors could explain the connection. For example, some research finds that highly religious people are less likely to take drugs, but more likely to be obese - perhaps because they are substituting compulsive behavior (overeating) to the other ( smoking marijuana). Thus, some obese people in national surveys can be religious people, who might otherwise be heavy marijuana smokers, but overeating instead. This could make it look like marijuana is slimming.

also consider that one of the most popular uses of medical marijuana to stimulate appetite in people with cancer, AIDS or other diseases. These patients are far less likely to be obese than the general population -. In this case, weight loss precede or require the use of marijuana

Whatever the explanation for the link between marijuana and less obesity, it is unlikely that cannabis could be used as an effective food aid. For one, pot smoking has been shown to increase appetite in several studies, at least in the short term, so it probably would not help dieters resist.

Second, a drug that has the opposite effect of THC, the primary psychoactive ingredient in marijuana, has itself been shown to help dieting. rimonabant called, at high doses the drug almost tripled the weight loss achieved by those taking a placebo. He also often caused severe depression and suicidal thoughts, though, so he was briefly approved by the European authorities, it was finally withdrawn.

Of course, none of this explains why the marijuana smokers in the samples of the national survey did not get bigger? taking a drug that can clearly stimulate appetite. One factor may be the tolerance :. Many of the effects of marijuana are reduced in frequent users, as the body adjusts to it

Another may be the substitution - smokers could be looking for comfort by smoking more marijuana, rather than eating more. Or, perhaps other ingredients in cannabis such as cannabidiol (CBD) may reduce the effects of the growing appetite of THC in the same way they reduce his paranoia-inducing properties.

Whatever the case, looking for marijuana never fails to surprise

They say that old habits have a hard life . A new study in the Journal of Clinical Investigation ( JCI ) suggests that prolonged obesity can cause structural changes in the brain, altering responsible for maintenance of healthy weight parts and ultimately undermine your weight loss plans.

The result is consistent with a number of recent studies that suggest that each person can have a natural "set point" weight that our bodies are trying to maintain. But it was difficult to understand why overweight and obese should have their "set points" so high. The new JCI study is among the first to suggest physiological mechanisms that could prevent heavy people too heavy, even after they have started to make changes in healthy lifestyle.

"To explain a biologically elevated body weight 'set point' field investigators have speculated about the existence of fundamental changes to neurocircuits the brain that control energy balance," lead author the study, Michael Schwartz, told reporters. "Our results are the first to provide direct evidence of such a structural change, and include evidence in humans and in mice and rats."

Although Schwartz cautions that its results are not the final word, this is what the new study found:

Rodents who became obese in a diet rich in persistent developed fats " neuronal injury "in the hypothalamus - part of the brain that regulates many metabolic functions, including hunger and fatigue As mice and rats continued to eat junk food, their brains began to show. damage in the area that controls the weight control.

PHOTOS: What makes you eat more food

Schwartz and colleagues then examined MRI scans of 34 obese humans, and found the same kind of injury among hypothalamus unusual raising the possibility that a common culprit may be at work in the promotion of obesity in speices.

The idea of ​​a body weight "set point" has promising implications for the treatment of obesity. Although it is well known that people will lose weight when they burn more calories than they consume, our bodies have many ways to adjust the calories we use during normal office day to day, as muscle repair. This means that even if someone can control his calorie consumption exactly, it can not control its total energy balance - or how much he eats less how it burns. - With the same kind of precision

In addition, changes in hormone levels can also promote or suppress appetite. A 2011 study in the New England Journal of Medicine found that when obese people lost weight, they usually known hormonal changes that lead to hunger, making it much more difficult to reduce calories and maintain the new lower weight.

PLUS How your diet can affect your risk of Alzheimer's disease

For obese then it seems like a vicious circle. Excess weight now means that if you manage to lose weight in the future, you still face potential challenges when trying to maintain that healthy weight. It is unclear from the study whether the change is reversible in the hypothalamus, but alterations may explain why people who were once heavy may struggle with hunger and find that the books slide back on so unexpected - and fast frustrating. Many studies confirmed that successful dieters often find much of their lost weight within one year of the diet - even when people are able to stay long-term diet. Seeing that weight back in turn can cancel the motivation for the future weight maintenance, and add to the vicious circle.

So is a diet a futile effort for those who are overweight? Not necessarily. You might be fighting not only your eating habits, but some very powerful biological signals to eat, eat, eat.

But even if you struggle with your weight, there is no reason to lose hope just yet. Lose all the weight is better than now lost eight, and Fitness and a good diet can make you feel energetic, healthier and happier even if you shed as much as you intended.

is that the second time is the charm for drug Qnexa diet? The Food and Drug Administration (FDA) review the data on the weight loss drug, again - an advisory group will meet on Wednesday - after rejecting the drug for approval once already in 2010.

Endocrinologic and Metabolic Drugs Advisory Committee voted the agency initially 10-6 against Qnexa's approval over concerns that it may increase heart rate and cause birth defects - concerns the FDA still has the second time. According to the FDA's disclosure documents, the Advisory Committee will be asked Wednesday to consider whether the manufacturer of Qnexa, Vivus, should conduct a clinical trial on cardiovascular risk before approval - a move that could delay significantly its reach in the market. Vivus proposes to post-approval study.

The key question for the panel is whether Qnexa is effective for weight loss - clinical trials suggest that it is, although in the second year of a trial, participants regained some of the weight they lost within the first year - but if its potential side effects outweigh its benefits.

Qnexa is a combination of two existing drugs - phentermine, an appetite stimulant suppression, and topiramate, an antiepileptic drug that is usually prescribed to control epilepsy, but also affects the appetite.

To address these concerns, the manufacturer of Qnexa, Vivus, suggested the drug is approved only for use in men and in women of childbearing potential not. This type of labeling work around did not meet the FDA, however, and the agency has asked the company to find a way to prevent pregnant women from using it.

Qnexa is not the first, it will not be the last weight loss pill to get approval from the FDA. The market is ripe for a new drug to help Americans lose weight, "We're really going to Weight Watchers to bariatric surgery regarding treatment options," said Joseph Nadglowski, president of the Obesity Action Coalition , an advocacy group for patients in Tampa, Fla., in an interview with Bloomberg. "For many, this is a pretty big difference."

But the FDA has an uneven history with diet drugs and an ever growing bar for new weight loss remedies. After a brief history of the success of the diet drug industry, failures and near misses.

Amphetamines
The original diet of drugs date back to the 1950s Amphetamines simply worked by stimulating the metabolism around, cause the body to burn more calories faster. The problem - as with any energy system pushed to its limits - was that the cells are not made to burn, burn, burn. They eventually burn, leading to heart problems, chest pain, palpitations, insomnia and other health problems.

Amphetamines, which stimulate energy and mood are as addictive as they tap into the brain's reward system. After their potential for abuse occurred, US and European officials have banned most amphetamine based drugs, but the drug is still available, often hidden in the diet remedies in South America.

Fen-phen and Redux
A new drug combination fenfluramine appetite suppressant and existing phentermine, fen-phen was all the rage in the mid-1990s, leading to a loss of weight in hundreds of thousands of Americans. In 1996, after media attention, the FDA approved a related drug, dexfenfluramine as Redux, which was the same as fen-phen, but with fewer side effects. However, the side effects were always serious: in the summer of 1997, the FDA revealed that 82 patients had developed defects in their heart valves while on fen-phen, and seven patients came down with the same condition on Redux. Other patients developed pulmonary hypertension, a potentially fatal lung disease, and JAMA study confirmed previous reports that both fen-phen and Redux caused brain damage in laboratory animals . After millions of prescriptions written in 1997 both fenfluramine and Redux were withdrawn from the market.

sibutramine (Meridia)
Since amphetamines made too much risk of addiction and other side effects, researchers have begun to focus on ways to trick the brain into want less food. Sibutramine, approved in 1997, worked on brain chemicals that affect appetite by blocking the reuptake of neurotransmitters such as norepinephrine and serotonin, the drug may suppress the desire to eat and convince the body that it was full, helping dieters to lose 5% to 10% of their body weight in a few months. After studies showed users were more likely to develop heart problems and stroke, however, the drug was withdrawn from the market in 2010.

Lorcaserin (Lorqess)
Because sibutramine, lorcaserin focused on changing brain chemicals, especially serotonin, convincing the body it was full. But an FDA panel recommended in 2010 against the approval of the drug because studies in which female rats taking the drug developed an alarming number of mammary tumors. The committee also asked the manufacturer to Lorqess, Arena, to perform additional tests on the drug's effect on users with diabetes and heart disease, conditions that commonly affect those who are overweight.

Contrave
A combination of two drugs already approved the antidepressant drug bupropion and naltrexone anti-addiction pill, Contrave has got the nod of an advisory committee to the FDA, which voted 13-to 7 for approval in 2010, but was ultimately rejected by the body itself over concerns that the drug increased the risk of heart attacks, strokes and other cardiovascular problems. The FDA said the minimal weight loss experienced by users (4.2%) does not justify the potential cardiovascular risks.

In another sign of FDA high threshold is set for diet drugs, the agency said Orexigen Therapeutics, the manufacturer of Contrave, would need to conduct further studies and long-term possible cardiac risks associated with Contrave, before approval would be considered. Such a trial would cost the company hundreds of millions of dollars -. enough to kill further development if Orexigen decides the diet market expected pill does not justify the cost

Orlistat (Alli, Xenical)
Currently, the only drug approved scheme on the US market, orlistat is available in two (Xenical) formulations over-the-counter (Alli) and prescription. Orlistat works not in the brain but in the intestine, promoting weight loss by preventing the body from absorbing the fat in food. The drug, which is intended to be used in combination with a low-fat diet and exercise program can help users lose 50% more weight than they would with diet and 'exercise. In this case, excess gas, oily or fatty stools and even oily stains

years when I was a broke student remaining on ramen noodles and off-brand cereal, I used to fantasize that one day when I had a good job, I would be able to afford to eat healthy incredibly. I intended to buy vegetables every week, belong to a fabulous gym, use a personal trainer and get regular massages.

But today, I still get sticker shock when I go to the grocery store. That is why I am so skeptical when a study by the USDA published a few months ago claimed that healthy foods are actually cheaper than the highly processed substance. These results are based on the fact that the old method prioritized price per calorie, junk food giving low cost advantage over vegetables. But, the report says, "When measured on the basis of edible weight or average portion size, grains, vegetables, fruits and dairy products are less expensive than most protein foods and foods high in saturated fat, added sugar, and / or sodium. "Translation: now there's really no excuse for not eating healthier

Yet it can be difficult to decide which are appropriate discretionary spending - especially if there is not much left after paying bills. It should be a conscious process. You need to understand what is most important to you and then make some compromises

For example, my friend Tracy hired a personal trainer, who tended his budget. She dropped the service, but it has become de-motivated to exercise on itself. I suggested him to continue working with the trainer while reducing outdoor dining and also wait to shop until after she fell to her waist pants desired - the two that helped her to motivate weight loss goal.

Plan ahead and . My mother worked outside the house when I was growing up and always expected the value of a week of meals that we can do all the grocery shopping at once.

previous research has shown that diet rich in saturated fats and trans fats is a no-no for maintaining a healthy heart. Now a new study from Brigham and Women's Hospital (BWH) goes further, finding these "bad" fats are associated with poor cognitive function and memory in women over time. Otherwise, "good" fats - monounsaturated fats such as in avocados and olive oil - are linked to a better understanding

Researchers analyzed approximately 6,000 women over 65 years in the study of women's health - a cohort of nearly 40,000 women over 45. The selected women participated in three cognitive-function tests which were spaced every two years over a four-year term.
