Calorie Restriction Reverses Type 2 Diabetes

An open Letter to President Obama:

Research presented at the Radiological Society of America’s annual meeting (Nov. 2011) shows that a cohort of obese men and women with type 2 diabetes mellitus was able to cure their disease by following a calorie-restricted diet: They eliminated their need for insulin medications.

After following a 500-calorie-a-day diet for four months – the average body mass index of the obese cohort dropped out of obesity into the overweight range at 27.5. AND indicators of cardiovascular function improved.*

As leaders of calorie restriction & practice, we recommend that people with type 2 diabetes or prediabetes, who follow a low calorie diet to reverse their disease, do so under medical supervision. Eating meals with as few calories as in the study is not necessary. A less restrictive plan that addresses the psychological needs of the patients has a better chance of long-term success. Care should be taken to make the diet delicious, flexible, and culturally friendly – so that people enjoy their dieting experience, and establish new eating habits that they will keep.

For the best chances of success, the diets should be planned to increase neurotransmitters that are known to make dieting easier. At the end of their weight loss period, patients should transition into eating more calories in a healthful mode that will sustain them for life. Few people will be able to implement this by themselves. So we utilize regular teleconferences and doctor participation programs, which greatly increase chances for success. Our program confirms research into best communications practice for weight loss programs.

Please help us reverse the tragedy of diabetes that ruins the lives of so many and that places an intolerable burden on the nation’s healthcare system. We need your help to make the medical community aware that the answer to this healthcare crisis may be just as simple as helping people to eat and live healthfully.

* “Lifestyle interventions may have more powerful beneficial cardiac effects than medication in these patients,” said the study’s lead author, Sebastiaan Hammer, M.D., Ph.D., from the Department of Radiology at Leiden University Medical Center in the Netherlands. “It is striking to see how a relatively simple intervention of a very low calorie diet effectively cures type 2 diabetes mellitus. Moreover, these effects are long term, illustrating the potential of this method.”
