Luke 'Groundskeeper Willie' Tulloch returns to educate us all! This episode Luke takes us through the MATADOR study and explains some of the key concepts that come from it - defining adaptive thermogenesis, the link between body mass and BMR, reversing metabolic adaptation, the body's mechanisms to conserve energy under caloric restriction, the impact of re-feeds and calorie cycling, metabolic flexibility and much more... There'll be a few laughs along the way as always!
