Low Carb Diet vs Low Fat Diet: Study Reveals Which is Best

Study shows which diet is better for weight loss

The war has been raging for a long time now in which diet may be best for weight loss between a low carb diet and a low fat diet.

A low carbohydrates diet restricts the carbs you eat in food such as potatoes, pasta and grains and concentrates more on you eating more protein and fat.

A low fat diet is one low in, surprise, surprise, fat. The foods typically eaten on this diet are whole grain foods, fruits and vegetables.

They are both said to have their benefits but a study shows the results at which one was better for losing fat.

Which one do you think came out top?

The theory goes that fewer carbohydrates lead to lower levels of insulin, which in turn lead to fat being released from the body’s stores.

In the study, 19 obese people were initially given 2,700 calories a day.

Then, over a period of two weeks they tried diets which cut their calorie intake by a third, either by reducing carbohydrates or fat.

The team analysed the amount of oxygen and carbon dioxide being breathed out and the amount of nitrogen in participants’ urine to calculate precisely the chemical processes taking place inside the body.

The Results showed that after six days on each diet, those reducing fat intake lost an average 463g of body fat – 80% more than those cutting down on carbs, whose average loss was 245g.

Dr Hall said there was no “metabolic” reason to choose a low-carb diet.

However, studies suggest that in the real world, where diets are less strictly controlled, people may lose more weight by reducing carbohydrate intake.

Diet claims ‘debunked’

They said the study had “debunked” many of the claims that low-carbohydrate diets were better, but the long-term impact was still unclear.

They added: “The most important message for now is probably that some carbohydrates are all right, especially the healthy whole-grain low-glycaemic-index variety.”

Prof Susan Jebb, from the University of Oxford, said: “The investigators rightly conclude that the best diet for weight loss is the diet you can stick to.
