Sports Nutritionist: How To Fuel Your Body Like an Elite Athlete



In this episode, Dr. Kristen Holmes sits down with performance dietitian Angie Asche to unpack the truth about fueling for peak performance. Angie shares what she’s learned working with elite male and female athletes—why under-fueling is far more common than overeating, how the pursuit of aesthetics can sabotage performance, and the critical role carbs, fats, and nutrient timing play in energy, recovery, and hormonal health.

They dig into the impact of fasting, sleep, inflammation, gut health, and supplements, challenge common myths around testing and “quick fixes,” and highlight the mindset work required to build a healthy relationship with food. From practical strategies to increase fiber and omega-3 intake to the key habits that support long-term metabolic health, this conversation is packed with actionable advice for anyone looking to perform, feel, and recover better—on or off the field.

  1. You don't need to (or want to) fuel your body like an elite athlete because 99.9999% of people are not elite athletes, those that are know what to eat and how much to eat for their sport and genetics, talking of genetics these people are freaks of nature, outliers that should be completely ignored. Eat a balanced diet of wholefoods drink water and be active, it's that simple for 99.9999% of the population.

  2. Research shows due to mercury it is best to supplement omegas and not try to eat any fish. Fish also only get it from algae anyway. Skip the middle man and get an algae supplement.

  3. This is an amazing interview and resource for anyone, not even just athletes. There’s so much misinformation around diet right now, this kind of scientific but accessible approach is so beyond important

  4. What if you work full time and train about 8-15-ish hrs on the bike. I work full time as a CTA and I’m pushing and pulling PTs, and I don’t eat my lunch between 11-11:15am. What do you recommend to fuel for training after work for say 2.5-4hrs of training during the work week?
