 Red wine contains piceatannol, which delays the generation of young fat cells 
  
 If you want to avoid gaining weight, it may be time to ditch the skipping rope and grab a corkscrew instead. 
  
 For U.S. experts have found a compound in red wine that can help control obesity. 
  
 The substance, piceatannol, delays the generation of young fat cells and prevents them from growing into mature ones. 
  
 It is also thought to protect the body from heart and neurodegenerative diseases, as well as cancer. 
  
 The compound blocks insulin’s ability to activate genes that carry out further stages of fat cell formation. 
  
  
  
 The agent found in wine is also thought to protect the body from heart and neurodegenerative diseases and cancer. 
  
  
  
 The groundbreaking research was carried out at Purdue University, Indiana, USA. 
  
 Lead researcher Dr Kee-Hong Kim said: 'In the presence of piceatannol you can see delay or complete inhibition of young fat cells. 
  
 'Piceatannol alters the timing of gene expressions, gene functions and insulin action during adipogenesis - the process in which young fat cells become mature fat cells. ' 
  
  
  
 Dr Kim, assistant professor of food science at the university, added: 'We are now testing our idea using animal model obesity to see if it has the same benefical functions. 
  
  
  
 'We need to work on improving the stability and solubility of piceatannol to create a biological effect.' 
  
  
  
 The compound is similar in structure to resveratrol - a supplement sold in the UK last year to combat disease - and is also found in grapes, blueberries and passion fruit.

 Nut consumers demonstrate lower BMI and waist circumference 
  
 'Tree nuts should be an integral part of a healthy diet,' says researcher Dr O'Neil 
  
  
  
 A study found that nut-consumers demonstrated a lower body weight, body mass index (BMI) and waist circumference 
  
 Dieters often dismiss them because of their high fat content, but research suggests that snacking on nuts can help keep you slim. 
  
 A study found that those who consumed varieties such as almonds, cashews and pistachios demonstrated a lower body weight, body mass index (BMI) and waist circumference compared to non-consumers. 
  
  
  
 They were also at lower risk of developing heart disease, type 2 diabetes and metabolic syndrome. 
  
 Experts are now r ecommending a daily intake of 1.5 ounces, or three tablespoons of nuts as part of a healthy diet. 
  
 Lead researcher Carol O'Neil, from Louisiana State University, said: 'One of the more interesting findings was the fact that tree nut consumers had lower body weight, as well as lower body mass index (BMI) and waist circumference compared to non-consumers. 
  
  
  
 'The mean weight, BMI, and waist circumference were 4.19 pounds, 0.9kg/m2 and 0.83 inches lower in consumers than non-consumers, respectively.' 
  
 In the study, published in the Journal of the American College of Nutrition, researchers compared risk factors for heart disease, type 2 diabetes and metabolic syndrome of nut consumers versus those who did not consume nuts. 
  
 They used data from 13,292 men and women participating in the 1999-2004 National Health and Nutrition Examination Surveys (NHANES). 
  
  
  
 Nut consumers were defined as those who ate more than one quarter of an ounce a day. 
  
 Tree nut - almonds, Brazil nuts, cashews, hazelnuts, macadamias, pecans, pine nuts, pistachios and walnuts - consumption specifically, was associated with higher levels of good cholesterol and lower risk of chronic diseases including heart disease. 
  
 In addition, it was also linked to a lower prevalence of four risk factors for metabolic syndrome: abdominal obesity, high blood pressure, high blood sugar levels and low good cholesterol levels. 
  
 Dr O'Neil adds: 'Tree nuts should be an integral part of a healthy diet and encouraged by health professionals—especially registered dietitians.' 
  
 Maureen Ternus, executive director of the International Tree Nut Council Nutrition Research & Education Foundation (INC NREF), also congratulated the recent data. ||||| Advice For Diet Soda Lovers: Skip The Chips

 Got a Diet Coke or Diet Pepsi habit? Lots of Americans do. Consumption of all types of diet soft drinks has been on the rise. And as a nation, we drink an estimated 20 percent more of diet drinks now than we did 15 years ago. 
  
  
  
 So, is it good for us? A new study finds the answer to that question may depend a lot on, well, what you eat. 
  
  
  
 Researchers at the University of North Carolina-Chapel Hill found that diet soda drinkers who ate a so-called "prudent" diet, rich in fruit, fish, vegetables, whole grains, nuts and milk, were significantly less likely to develop metabolic syndrome over 20 years than those who ate a "Western diet" heavy in fried foods, meats and sugars. 
  
 Metabolic syndrome is a condition characterized by excess abdominal fat, elevated blood sugar, high blood pressure, elevated triglycerides and low HDL cholesterol. About 32 percent of the participants in the "Western diet" cluster developed the condition. 
  
 Update at April 13, 2012, 11:05 ET: By contrast, 20 percent of people who drank sodas and had a prudent diet had metabolic syndrome. And 17.8 percent of prudent eaters who drank no soda had that problem. 
  
 End update. 
  
 Those with the lowest risk of developing metabolic disorder were the participants who followed the "prudent" diet and also drank no diet soda at all. 
  
  
  
 The study is published in the April edition of the American Journal of Clinical Nutrition. 
  
  
  
 "What this suggests is that it's really the dietary pattern that's driving this association with health," says Kiyah Duffey, a research assistant professor at the UNC School of Public Health and study author. She says a few prior studies have found that people who consume diet soda regularly may be at higher risk of developing metabolic disorder. 
  
  
  
 "This kind of helps to make things a little more clear that it's not necessarily the diet beverage that is the problem," says Duffey. 
  
 The question of whether diet soda truly helps people manage their weight turns out to be a very tough one to answer. 
  
  
  
 Conflicting findings abound. A large study published in the New England Journal of Medcine last year found that diet soda had no effect on weight. But another one, published in 2008, found that drinking more than three diet drinks a day led to weight gain. 
  
  
  
 The American Heart Association doesn't have specific guidelines on diet soda consumption, but spokesperson Rachel Johnson of the University of Vermont says moderate consumption seems fine. "But what the mistake a lot of people make is that they compensate for the calories that they save in the diet soda with other foods and beverages," says Johnson. 
  
  
  
 And many experts say the diet soda habit is a good alternative to sugar sweetened beverages that are clearly linked to diabetes, cardiovascular disease and increased health care costs. ||||| Struggling to sleep? You'll pile on the pounds: Less than five and a half hours is bad for your weight 
  
 Could explain why night workers who struggle to sleep during the day are more prone to being overweight

 Sleepy: According to scientists, getting less than five and a half hours of sleep a night could see you gain nearly a stone in a year 
  
 Have you been getting enough beauty sleep lately? If not, this might encourage you to turn in a little earlier. 
  
  
  
 According to scientists, getting less than five and a half hours of sleep a night could see you gain nearly a stone in a year. 
  
  
  
 They say that even if diet and exercise habits remained the same, the changes in the body’s metabolism can cause the pounds to pile on. 
  
  
  
 The team of researchers believe this could explain why people tend to become larger as they get older and often struggle to get enough sleep at night. 
  
  
  
 They also think it could explain why night shift workers who struggle to sleep during the day are more prone to being overweight. 
  
  
  
 The academics from Boston compared the effects of sleep on 21 volunteers over six weeks. 
  
  
  
 They started off having ten hours of sleep a night but this was then reduced to just over five and a half hours at any time during the day. 
  
 Often volunteers were attempting to doze off during the day time when their body clock was telling them that they should be up and about. 
  
 The researchers found that when the subjects were deprived of sleep their metabolism rate dropped by 12 per cent. 
  
 Increase: It was calculated that when the volunteers slept for less than five and a half hours they burned off 120 fewer calories that day. Over the course of a year this would lead them to put on 12.5 pounds, just under a stone 
  
 This is energy needed to maintain the body’s normal functions such as the lungs breathing and heart beating. 
  
 If this rate comes down, less energy or calories will be used up so weight will be gained – even if exercise levels and diets are unchanged. 
  
  
  
 It was calculated that when the volunteers slept for less than five and a half hours they burned off 120 fewer calories that day. 
  
  
  
 Over the course of a year this would lead them to put on 12.5 pounds, just under a stone. 
  
  
  
 The researchers said this could explain why people who work at night are more likely to develop obesity and diabetes. Their body clock or ‘circadian rhythm’ is disrupted so they are unable to sleep as well during the daytime and their metabolism slows down. 
  
  
  
 Dr Orfeu Buxton, whose study is published in the journal Science Translational Medicine, said: ‘Since night workers often have a hard time sleeping during the day, they can face both circadian disruption working at night and insufficient sleep during the day.

Output:
A wealth of findings offer some new tips to keep off the pounds. Looks like tree nuts, red wine, and plenty of sleep can all help you stay fit. Researchers found that nut eaters weighed less and had a lower waist circumference and BMI than those who don't eat nuts, the Daily Mail reports. The snacks may also help fight heart disease. Meanwhile, scientists have spotted a compound in red wine that battles obesity by slowing the growth of fat cells. The compound, piceatannol, may also fight neurodegenerative diseases and cancer, the Mail notes. Sleep habits can also have an effect on your weight: Research subjects who got less than five and a half hours burned some 120 fewer calories a day, leading to a 12.5 pound weight gain over a year. (Another study finds that those who sleep less also consume more calories.) Lastly, some news for diet soda fanatics: What you eat is apparently more important than what you drink. Some 32% of diet soda drinkers who ate a "Western" diet of meats, fried food, and sugars developed metabolic syndrome over two decades, compared to 20% of diet soda fans who ate a "prudent" diet of fruits and veggies, fish, and whole grains. The lowest risk, at 17.8%? Those who followed a "prudent" diet and drank no soda, NPR reports.
