Posted on February 4, 2013 by Robert Barrington

Leptin acts as a feedback signal to the hypothalamus to decrease appetite and increase metabolic rate as adipose tissue accumulates. Administration of leptin to ob/ob leptin deficient mice causes dramatic reductions in body weight. From these results it was hoped … Continue reading →

A Closer Look at Protein

Posted on August 22, 2012 by Robert Barrington

Many research papers investigate macronutrient ratios and their effects on various physiological parameters. However, there is a tendency to oversimplify the categories and treat protein, fat and carbohydrate as single uniform macronutrients. This oversimplification does disservice to the science of … Continue reading →
