Summary

Episode 119: Krista Casazza PhD, discusses myths surrounding obesity, the role of epigenetics and the importance of the musculoskeletal system in weight loss maintenance and metabolic health.

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.

0:00.0	Definitely genetics plays a role.
0:05.0	But genetics plays a role in the fact that not only is it genetic in terms of genotype and epigenetic in terms of response to the diet,
0:17.0	but also in genetic in the genetic influence on the environment.
0:21.6	So obese parents indeed have obese kids, but obese parents also eat and have physical activity behaviors
0:28.6	that are very similar to their obese kids.
0:31.6	But it's the genetic effects that predispose them to a particular environment.
0:35.6	So if you can counter that environment, you not only can counter the expression of the gene,
0:41.3	but also break that genetic passing on
0:44.3	of sedentary behavior or poor diet quality. Hello and welcome to Sigma Nutrition Radio, the podcast that brings you weekly in-depth discussions with some of the brightest minds involved in evidence-based nutrition research and its application.
1:17.0	I am your host, Danny Lennon, and you are listening to Episode 119.
1:22.6	And today we are going to be discussing obesity with one of the key researchers in this field,
1:28.3	Dr. Krista Kazaza.
1:30.3	Dr. Kazaza is an associate professor in the Department of Pediatrics at the University of Alabama,
1:36.3	and she's working primarily with the pediatric population, with her research interest
1:42.3	having evolved into understanding the resource partitioning
1:46.0	during critical growth periods and development with the primary focus on the bone fat interface.
1:52.0	So essentially the importance of the musculoskeletal system in not only prevention and treatment of obesity,
2:00.0	but how that affects other issues such as, say,
2:03.4	sarcopenia, for example. The show notes to this particular episode with links to all the
2:08.7	resources we'll mention and a full PDF transcript of the episode will be available over at
2:15.0	sigma nutrition.com slash episode 1119.
2:19.0	So if you go there, you can get all of that stuff,
