Weight loss diet

In healthy obese men
received two different diets during their stay in the specialized
Rowett Human Nutrition Unit. Both schemes have a high protein content
(30% of the energy from the diet), but they differ in the amount of
carbohydrates: A diet low in carbohydrates was (4%) and the other
contained a moderate amount of carbohydrates (35% of total energy
value).

"Our volunteers have found the two regimes to be
just as palatable, but they were less hungry on the high-protein diet
low in carbohydrates compared to food containing high protein content,
but moderate amounts of carbohydrates, "said Dr. Alex Johnstone,
Rowett's weight loss expert who led the study.

"Weight loss
during the two periods of four weeks of study was greater on the
high-protein diet low in carbohydrates, with an average of 6.3
kilograms per person, compared to 4.3 kilograms on diet moderate in
carbohydrates, "said Dr Johnstone.

An important part of this
study was to dismantle the physiological mechanisms of this type of
diet. It is well known that when people eat diets low in carbohydrates,
in a relatively short time, their body has to switch from using glucose
as a fuel with something different called ketones. Corps ketonic are
suppression of appetite and may have an effect on the appetite centers
in the brain. It is also well known that the protein itself is very
good at making people feel full.

"In this study we showed
that on the high-protein diet low in carbohydrates, volunteers have
become ketogenic start in 1-2 days of this regime and therefore it is
possible that the high protein content, low-carbohydrate diets are
particularly effective because of the combined effect of the protein
and ketones, "said Dr Johnstone.

"We have shown that
volunteers on the ketogenic reduced their energy intake without
increasing their hunger, which is a very important factor in their
ability to stick to the diet"...
