Study of obese diabetics explains why low-carb diets produce fast results

15.03.2005


A new study by Temple University School of Medicine researchers has shown why the pounds melt so quickly on low-carbohydrate diets, and it’s not related to water, metabolism or boredom. The research was conducted in a group of obese patients with type 2 diabetes who followed the Atkins diet.



According to lead researcher, Guenther Boden, M.D., "When carbohydrates were restricted, study subjects spontaneously reduced their caloric intake to a level appropriate for their height, did not compensate by eating more protein or fat, and lost weight. We concluded that excessive overeating had been fueled by carbohydrates."

Almost 80 percent of diabetics are overweight or obese, compounding health risks such as heart disease and stroke. Boden wanted to examine how low-carbohydrate diets, which have been shown to produce rapid weight loss, affected weight, appetite and blood sugar in obese diabetics.


He discovered that study subjects did not eat less because they were bored with the food selection, and their weight loss was not attributable to water loss, two common speculations about low-carb diets. Further, weight loss could not be explained by a change in metabolism, another popular misconception.

The study, "Short-Term Effects of Low-Carbohydrate Diet Compared with Usual Diet in Obese Patients with Type 2 Diabetes," is published in the March 15 issue of the Annals of Internal Medicine. It is the only study of the Atkins diet to have been conducted in the strictly controlled environment of a clinical research center where every calorie eaten and spent was measured.

After a week of typical eating, ten obese patients with type 2 diabetes followed the Atkins diet for two weeks, with carbohydrates limited to 20 grams per day and unlimited protein and fat.

"When we took away the carbohydrates, the patients spontaneously reduced their daily energy consumption by 1,000 calories a day. Although they could have, they did not compensate by eating more proteins and fats and they weren’t bored with the food choices. In fact, they loved the diet. The carbohydrates were clearly stimulating their excessive appetites," said Boden.

All patients stayed in the hospital for the length of the study to insure exact measurements of calorie intake and expenditure. In other studies of the Atkins diet, subjects were at home and reported their own diet and exercise, making it difficult to ensure accuracy.

In addition to the calorie reduction and weight loss, subjects experienced markedly improved glucose levels and insulin sensitivity, as well as lower triglycerides and cholesterol.

Treatment for diabetes centers on closely monitoring sugar levels, diet and medication. Weight loss can often reduce or eliminate the need for medication, including insulin.

Boden warns that the long term effects of low-carbohydrate diets are not known. Whether other types of diets would have a similar impact also remains to be investigated.

Other research projects of Boden’s include a National Institutes of Health supported study of obesity-associated diabetes and cardiovascular disease.

This study was funding by grants from the National Institutes of Health and the American Diabetes Association.

Im Focus: BAM@Hannover Messe: innovative 3D printing method for space flight

At the Hannover Messe 2018, the Bundesanstalt für Materialforschung und-prüfung (BAM) will show how, in the future, astronauts could produce their own tools or spare parts in zero gravity using 3D printing. This will reduce, weight and transport costs for space missions. Visitors can experience the innovative additive manufacturing process live at the fair.

Powder-based additive manufacturing in zero gravity is the name of the project in which a component is produced by applying metallic powder layers and then...

Im Focus: Molecules Brilliantly Illuminated

Physicists at the Laboratory for Attosecond Physics, which is jointly run by Ludwig-Maximilians-Universität and the Max Planck Institute of Quantum Optics, have developed a high-power laser system that generates ultrashort pulses of light covering a large share of the mid-infrared spectrum. The researchers envisage a wide range of applications for the technology – in the early diagnosis of cancer, for instance.

Molecules are the building blocks of life. Like all other organisms, we are made of them. They control our biorhythm, and they can also reflect our state of...

Im Focus: Spider silk key to new bone-fixing composite

University of Connecticut researchers have created a biodegradable composite made of silk fibers that can be used to repair broken load-bearing bones without the complications sometimes presented by other materials.

Repairing major load-bearing bones such as those in the leg can be a long and uncomfortable process.

Im Focus: Writing and deleting magnets with lasers

Study published in the journal ACS Applied Materials & Interfaces is the outcome of an international effort that included teams from Dresden and Berlin in Germany, and the US.

Im Focus: Gamma-ray flashes from plasma filaments

Novel highly efficient and brilliant gamma-ray source: Based on model calculations, physicists of the Max PIanck Institute for Nuclear Physics in Heidelberg propose a novel method for an efficient high-brilliance gamma-ray source. A giant collimated gamma-ray pulse is generated from the interaction of a dense ultra-relativistic electron beam with a thin solid conductor. Energetic gamma-rays are copiously produced as the electron beam splits into filaments while propagating across the conductor. The resulting gamma-ray energy and flux enable novel experiments in nuclear and fundamental physics.

The typical wavelength of light interacting with an object of the microcosm scales with the size of this object. For atoms, this ranges from visible light to...
