Grant Tinsley | The Science and Significance of Intermittent Fasting on Body Composition and Performance

Among all dietary approaches, there may not be any that have more intrigue, or confusion, than intermittent fasting (IF). Luckily, Dr. Grant Tinsley joins the show to explain the research on IF and its significance for your performance, body composition, and health.

Listen as we dive into the research on intermittent fasting, its potential benefits and limitations, the physiological effects of fasting, and how it compares to normal calorie restriction. We also discuss the individual variability in response to fasting. Grant shares insights from his various studies on intermittent fasting combined with resistance training, and their findings on performance and body composition.

Finally, we explore the individual variability in response to a 24-hour fast, touching on food cravings, hunger levels, and the impact of factors like alcohol consumption and timing of the last meal before starting the fast.
