Guest Bio

Krista Casazza, PhD. 
 krista

Dr. Casazza is an associate professor in the Department of Pediatrics at the University of Alabama.

Working with the pediatric population, Dr. Casazza’s research interest have evolved into understanding the resource partitioning during critical periods of growth and development with primary focus on the bone fat interface.

Krista Casazza obtained her PhD from Florida International University in 2006, where her research focused on dietary and physical activity education interventions in adolescents. During her training Dr. Casazza investigated the effects of macronutrient modification (carbohydrate in particular) on reproductive hormones, insulin dynamics and body composition during a weight loss intervention in peri-pubertal African American girls.

 In this episode we discuss:

  • Musculoskeletal considerations in weight loss
  • Importance of muscle for metabolic health and glucose uptake
  • Rates of weight loss in obesity: fast vs. slow & “sustainable”
  • Goal setting in obesity treatment
  • The problem with modest calorie deficits
  • Genetic pre-disposition to obesity & the role of epigenetics
  • Practicalities of obesity treatment
  • The folly of “eat less” as advice
  • Impact of diet quality on outcomes
  • Myths surrounding the importance of breakfast in weight loss/gain
