The new results could lead to treatments designed to curb that inflammatory state, and the insulin resistance and type 2 diabetes that come with it.

The benefits of a diet lower in glycotoxins are present even without changing caloric or nutrient intake.

In a new commentary, researchers more precisely clarify the concept of the energy gap (or energy gaps) and discuss how the concept can be properly used as a tool to help understand and address obesity.

Larvae in which this gene is defective lose their entire fat reserves. Mammals carry a group of genes that are structurally very similar. The scientists therefore hope this research could lead to new medicines to fight obesity.

There is no need for more than two hours of fasting before inguinoscrotal region surgery. Further studies in surgical patients should help to substantiate the safety and clinical benefits of this new concept.
