Losing weight: who follows low-carbohydrate diet, more calories


A severe reduction in carbohydrate consumption and the consumption of more fat can help your body burn more calories. This was shown by a recent US study.

Increase your calorie consumption – a dream for many people who want to lose weight. One way to do this is to eat more fat – this at least points to the outcome of a recent study.

Carbohydrates diet less calories

Researchers found that out of 164 adults who participated in the study, those with low carbohydrates with high fat content lit more calories per day than those on foods rich in carbohydrates.

Scientists estimate that a diet high in fat would result in an additional weight loss of about 10 kilograms over a three-year period for an average person.

"The study is contrary to conventional thinking that it's only critical reduction in weight loss in calories," says senior researcher dr. David Ludwig.

Instead, says the doctor, the source of consumed calories can make a difference.

This affects whether metabolism works "for you or against you".

Reduce the amount of carbohydrates instead of calories

According to Ludwig, the results of the study support a theory called the "carbohydrate-insulin model".

The presumption is that diets that are high in processed carbohydrates increase insulin levels, which makes the body consume less calories – and instead saves more than fat.

"Our study suggests that it's better if we focus on reducing refined carbohydrates and not just focusing on calorie reduction," explains the doctor.

Different starting point than previous studies

Countless studies have already tried to clarify the question of whether a diet with low fat or low carbohydrates is better to lose weight. It is often the result that there is no difference anymore.

The criticism of these studies, according to Ludwig, is that these are usually behavioral studies in which subjects did not always follow the prescribed diet or at least could not be verified if they did so.

That's why his team decided on a "feeding study" where subjects were eating under the supervision of the clinic, which enabled them to accurately control what people actually ate.

First, 234 overweight and obese adults were employed in the deployment phase.

The goal of the participants during this time: losing about twelve percent of their body weight in ten weeks.

From this group, 164 fell enough to go to the next stage: over a period of 20 weeks, the rest of the subjects had either to follow low carbohydrates, moderate carbohydrate diets or a high carbohydrate diet.

The difference is the difference

Low carbohydrate subjects have created 20 percent of their calories from carbohydrates such as vegetables, fruits and beans.

By contrast, 60 percent of their calories come from fat, including meat, whole milk, cheese and nuts. The remaining 20 percent of calories came from protein.

With a high carbohydrate content the whole thing was different: 60 percent of calories came from carbohydrates and 20 percent fat.

The moderate plan distributed equally between the two nutrients in the ratio of 40 to 40.

The aim of the researchers was to determine the effects of different diets in burning calories.

Result: A low carbon group has extracted more calories – on average more than 250 more per day in the 20-week study period than a high carbohydrate group.

Contrary to the moderate group of carbohydrates, 111 additional calories were made in the low carbohydrate group.
