We have an exciting announcement at Iron Culture, we are combining forces with MASS, Monthly Applications in Strength Sport to bring you regular “MASScast” episodes where we will be joined by one or more of the expert MASS reviewers to talk science. In this inaugural MASScast episode we’re joined by Dr. Eric Trexler to discuss surprising recent data that suggests basal metabolic rates have been decreasing at the population level over recent decades. Is this true? And if so, what’s causing it? In addition, we discuss the continuing confusion regarding high versus low-carb diets. Where is the cut-off for being high or low carb, and when is each a good or bad approach? Listen in to learn what the latest data indicates and how to apply it!
