He performed work in Africa, the Netherlands, the Middle East, Malta and the Netherlands Antilles, where he devoted the past 30 years to the relationship between lifestyle and disease. His particular focus is the science of aging and obesity, with healthy food, food supplements, relaxation and exercise.

Based on research by the British doctor Dr. A.T.W. Simeons and the Dutch physician Dr. F.L.L.M. Merckelbach, he has updated and refined the HCG weight loss program into an ambulatory treatment program.
He invented and developed the new Weightdrops formula and proved its successful support in losing weight, in a single-blind study (HCG versus Weightdrops).
