Proper Vitamin D Intake May Lead To Healthy Weight Loss

Following a diet enriched with vitamin D may be associated with achieving better weight loss results, according to a study published in the American Journal of Clinical Nutrition.

Over the course of two years, more than 300 individuals aged 40 to 60 who were considered overweight followed three different diets, which all featured foods that contain high levels of vitamin D. The regimens included a low-fat diet, a low-carbohydrate diet and a Mediterranean-inspired diet.

The results of the study showed that each diet led to healthy weight loss, but the participants who consumed the most nutrient-enriched foods lost more weight.

It was known that overweight people had lower levels of serum vitamin D, but this is the first study that actually shows that serum vitamin D increased among people who lost weight,” said Danit Shahar, lead author of the trial. She added that these findings “lasted throughout the two years that the study was conducted, regardless of whether they were on a low-carbohydrate, low-fat or Mediterranean diet.”

In addition to promoting healthy weight loss, vitamin D intake may also improve bone health, prevent low bone mass, reduce bone density loss and lessen the chance of osteoporosis.

DNA Test ‘May Predict Suitable Diet’

A simple DNA test may predict whether someone is more likely to lose weight on a low fat or a low carbohydrate diet, say US researchers.

The results from the small preliminary study of 101 women showed those on the best diet for their genes lost two to three times more weight than the rest.

The results are being presented at an American Heart Association conference.

Experts said the findings tied in with previous studies, but further work should be carried out.

Cheek swab:-

The emerging field of “nutrigenomics” looks at how food interacts with genes.

It has long been known that people react to certain nutrients differently according to their genetic makeup.

Lactose intolerance, for example, is more common among Asians and Africans than of people of North European descent.

This study looked at how well people with different genes fared on different weight-loss diets.

The researchers, from Stanford University, analysed data from 101 white Caucasian women who provided DNA from a swab of their cheek cells.

The women had different diets for a year. The diets were very low carbohydrate, low carbohydrate/high protein, and low or very low fat.

The researchers divided the group into three genotypes which they described as low carbohydrate diet responsive, low fat diet responsive and a balanced diet responsive genotype.

They found that those on a diet which matched their genotype lost 2-3 times more weight over 12 months compared with those on the “wrong” diet.

The researchers said their findings were preliminary, and need much more confirmation before they could be used commercially.

‘Intriguing’

British experts pointed out that the study had looked at a very small number of people and did not make clear what genes were involved.

Prof Christine Williams, from the University of Reading, said: “This is a very intriguing study – though very small.”

She said it would be useful to get a better understanding of what genes were involved.

“It fits pretty well with some of our own studies which show that certain genotypes are more responsive than others to certain types of fats, eg diets high in omega-3 fatty acids,” she added.

‘Spoonful of Sugar’ Makes The Worms’ Lifespan Go Down

If worms are any indication, all the sugar in your diet could spell much more than obesity and type 2 diabetes. Researchers reporting in the November issue of Cell Metabolism say it might also be taking years off your life.

By adding just a small amount of glucose to C. elegans’ usual fare of straight bacteria, they found the worms lose about 20 percent of their usual lifespan. They trace the effect to insulin signals, which can block other life-extending molecular players.

Although the findings are in worms, Cynthia Kenyon of the University of California, San Francisco says there are known to be many similarities between worms and people in the insulin signaling pathways department.

As an aside, Kenyon says she read up on low-carb diets and changed her eating habits immediately — cutting out essentially all starches and desserts — after making the initial discovery in worms. The discovery was made several years ago, but had not been reported in a peer-reviewed journal until now.

Older People More Fit Than Yonger

The average 50-year-old is now healthier and fitter than someone half their age, a study revealed .

50+ woman golfing.25-yr. old working in computer
Researchers found the average 25-year-old consumes over 2,300 calories a day, exercises only three times a week and indulges in 12 portions of junk food a month.

But the typical 50-year-old has only 1,990 calories each day, does at least four forms of exercise and treats themselves to just one piece of junk food each week.

And while those in their mid-20s treat themselves to three takeaways a month, the older generation have only one.

The study, commissioned by global nutrition and direct selling company Herbalife, quizzed 4,000 Brits on their diet and lifestyle.

Neil Spiers, Herbalife’s Regional Vice President, said: ‘The results of the study will be surprising to most as it’s natural to think that the younger you are, the fitter you are.

‘It seems many young people are making the mistake of underestimating the benefit of a more balanced, holistic approach to diet and lifestyle.

‘It’s great to think that the older generation are showing the youngsters the way when it comes to healthier living.’
The nationwide research of 16-80 year olds surveyed them about their health and exercise habits.

It found the over-50s are more likely to walk as much as they can during the day – to the shops or with the dog – while those in their 20s tend to drive everywhere.

When it comes to excuses for not exercising, over a third (36 per cent) of 25 year olds blame not having enough time, compared to 22 per cent of over-50s.

The research found 70 per cent of Brits see themselves as healthy – exercising for 27 minutes a day, at least three times a week, opting to go for a walk, run, cycle or gym.

A quarter of Brits polled cycle to see friends or go to the shops, and 70 per cent take the stairs instead of the lift.

Nearly four in 10 walk to the train station or to work in a bid to keep fit.

The study also found the average Brit believes they are overweight by nine pounds.

Over a quarter of the population are currently on a diet – with the ‘low fat‘ (30 per cent), ‘low carb‘ (14 per cent) and ‘detox’ (eight per cent) diets being the most popular.

And they would wish to lose 13 pounds for them to be their ideal weight.

The study also highlighted the lengths people will go to in order to hide their true weight.

Nearly a quarter have fibbed about the amount they eat, one in five has actually lied about their weight and 12 per cent have cut labels out of clothing which revealed their real size.

A cheeky 16 per cent have turned to slimming aids without telling anyone and seven per cent have uploaded misleading pictures on Facebook.

And 30 per cent have ‘binge dieted’ to fit into a dress or to look good in a bikini in time for a holiday.

Less Carbs Slow Prostate Tumour Growth

Cutting down on carbohydrates may slow prostate tumour growth, according to a study conducted on animals.

“Researchers believe that insulin and insulin-like growth factor contribute to the proliferation of

prostate cancer,” said Stephen Freedland, urologist at the Duke Prostate Centre and lead investigator on this study.

“Previous work here and elsewhere has shown that a diet light in carbohydrates could slow tumour growth. But the animals in those studies also lost weight and because we know that weight loss can restrict the amount of energy feeding tumours. We weren’t able to tell just how big an impact the pure carbohydrate restriction was having until now,” Freedland added.

Animals in the study were fed one of three diets: a very high fat/no carbohydrate diet, a low-fat/high carbohydrate diet and a high fat/moderate-carbohydrate diet, which is most similar to the diet most Americans eat, Freedland said.

They were then injected with prostate tumours at the same time.

“The mice that were fed a no-carbohydrate diet experienced a 40-50 percent prolonged survival over the other mice,” Freedland said.

Mice on the no-carbohydrate diet consumed more calories in order to keep body weights consistent with mice on the other study arms. “We found that carbohydrate restriction without energy restriction – or weight loss – does indeed result in tumour growth delay,” he said.

Patients are likely to be recruited by Duke and California (Los Angeles) Universities, for further clinical trials within a few weeks, said a Duke release.
