Most Effective Weight Loss Diet Revealedhttp://www.medicalnewstoday.com/articles/93809.phpScientists at Aberdeen's Rowett Research Institute have shown that a

high protein, low carbohydrate diet is most effective at reducing

hunger and promoting weight loss, at least in the short term. Their

work has just been published in the American Journal of Clinical

Nutrition. Healthy, obese men were given two different diets

during their stay in the Rowett's specialised Human Nutrition Unit.

Both diets had a high protein content (30% of total energy value of the

diet) but they differed in the amount of carbohydrate: One diet was low

in carbohydrate (4%) and the other contained a moderate amount of

carbohydrate (35% total energy value).

" Our volunteers found both diets to be equally palatable, but they felt

less hungry on the high-protein low-carbohydrate diet compared with the

diet which contained high-protein but moderate amounts of

carbohydrate, " said Dr stone, the Rowett's weight-loss expert

who led the study.

" Weight loss during the two four week study periods was greater on the

high-protein low-carbohydrate diet, averaging 6.3 kg per person,

compared with 4.3 kg on the moderate carbohydrate diet, " said Dr

stone.

An important part of this study was to unravel the physiological

mechanisms behind this type of diet. It is known that when people eat

low carbohydrate diets, within a relatively short time their body has

to switch from using glucose as a fuel to using something different

called ketone bodies. Ketone bodies are appetite-suppressing and they

may have an effect on the appetite centres in the brain. It's also well

known that protein itself is very good at making people feel full-up.

" In this study, we showed that on the high-protein low-carbohydrate

diet the volunteers became ketogenic within 1-2 days of starting this

diet and so it may be that high-protein, low-carbohydrate diets are

particularly effective because of the combined effect of the protein

and the ketone bodies, " said Dr stone.

" We showed that the volunteers on the ketogenic diet reduced their

energy intake without increasing their hunger and this was a very

important factor in their ability to stick to the diet. "

Dr stone sounds a note of caution about her findings: " A paper

published last year from the same study showed that low carbohydrate

diets may have consequences for the health of the gut by dramatically

reducing the numbers of particular types of bacteria. So we will be

looking in more detail at the complex way in which we respond to

changes in our diet before we can say whether low-carbohydrate

ketogenic diets are a suitable tool for everyone who wants to lose

weight. "

When the phase of the study which involved the volunteers finished in

October 2004, it attracted considerable interest because of its

celebrity volunteer, Cameron Stout, who lost just over 12 kg during his

nine week stay at the Rowett Institute. At the time, Cameron mentioned

his surprise at not feeling hungry during the study and said he had

adjusted to eating smaller portions. How does he feel now, three years

later?

" I had a great experience with the nutrition study at the Rowett. The

food was excellent and the staff looked after us very well. Because I

have such an irregular lifestyle I don't find it easy to stick rigidly

to all that I learnt while I was at the Institute, but I try to make an

effort most of the time. For me it was mainly about breaking bad habits

and I guess we all have food vices we need to deal with! " said Cameron. ROWETT INSTITUTE
