Dr. Andy Galpin: Optimal Nutrition & Supplementation for Fitness | Huberman Lab Guest Series

Nutrient Timing

Nutrient timing plays a crucial role in optimizing performance and recovery. Andy Galpin emphasizes that while total protein intake throughout the day is vital for muscle growth, the timing of carbohydrate intake is more critical for performance, especially when training multiple times a day 1. He suggests a general guideline of consuming half a gram of carbohydrate per pound of body weight, adjusting based on energy expenditure and workout intensity 1.

The timing of carbohydrate does matter. It needs to be around and available so you can maximize both hydration and muscle glycogen resynthesis.

Additionally, Galpin highlights the importance of using a combination of glucose and fructose during workouts to maximize carbohydrate intake and enhance performance 2.

   

Training Fasted

Training in a fasted state can have varying effects on performance and energy levels. Andrew Huberman shares his personal preference for fasted weight training, noting that caffeine seems more potent when consumed in a fasted state 3. However, Andy Galpin advises that while some athletes can maintain performance when training fasted, it is not typically optimal for high-intensity or long-duration activities 4.

I can't think of a scenario in which I would go to fasting to try to enhance performance.

--- Andy Galpin

He stresses the importance of ensuring glycogen stores are topped off from the previous day's nutrition to support performance when training fasted 4.
