...d PPAR-delta, increases the rate at which the body burns fat. This makes PPAR-delta an exciting potential target for drugs that treat diabetes and lipid disorders. The team produced a genetically engineered mouse endowed with the activated form of PPAR-delta in its skeletal muscles.

...The end result: Food intake is inhibited. The body burns more calories. PC1 and PC2 perform their crucial protein-cutting function not only on the chemical forerunner of TRH, but on several metabolic brain messengers, researchers say. These include insulin, the hormone that controls blood sugar. This findi...Lehmann lovegrass won't succumb to fire

To keep prescribed burns under control, many land managers prefer to burn grasslands in the spring, when the plants and soil have more moisture, and the temperatures are cooler.

...ood intake, but their metabolism rose. "The animal burns off more calories, so over time loses weight, which was very fascinating because we knew that leptin caused weight loss by suppressing appetite and increasing metabolic rate," explains Ahima.
