The VALidity Podcast
The VALidity podcast discusses and educates on scientific topics relevant to your health and fitness. Valentina Rodriguez earned her Master's degree in Exercise Science with a concentration in Physique Enhancement from USF while working under Dr. Bill Campbell as his research coordinator. This podcast brings you everything she learned–basically a free master's education!!
Every week, she'll cover new topics in training, nutrition, fat loss, muscle gain... really anything that could be pertinent to your fitness goals.
We get into the concepts, the research, the nitty gritty science so come ready to learn.

Your Gut Is Controlling Your Body Weight

In this episode, we break down the gut-brain axis—the complex communication network that regulates hunger, metabolism, and body weight. We explore how the brain integrates signals from fat tissue, nutrients, nerves, and gut hormones like GLP-1 and CCK to control appetite and energy balance. From classic obesity research to modern discoveries about vagal signaling, nutrient sensing, and incretin hormones, we uncover how the body normally maintains weight—and why highly palatable foods and modern environments can override these systems.
