In this episode, we talk through what stood out to us, including updated protein recommendations, how fats and added sugars are positioned, and what the guidelines emphasize about real food.

If you’ve ever stood in front of a wall of plant-based protein bars wondering which one actually to choose, this episode is for you. We break down the crowded protein bar landscape by reviewing a handful of vegan options (NuGo, IQ Bar, TruBar, and Aloha) and talk through what ingredients, macronutrient profiles, and other details to consider when you’re making a choice.

If you’re heading into a new season with the same fueling plan, it might be time to pause and ask one important question: "Should I change my sports nutrition?"

In this episode, we talk through when it makes sense to change your sports nutrition and how to recognize signs that your current fueling approach may no longer match your training or your body. If you’re an endurance athlete or team sport athlete wondering whether your nutrition plan still fits your goals for this season, this conversation will help you think more clearly about when to adjust and when to stay the course.

Alcohol doesn’t just affect you the night you’re drinking - it influences how you sleep, recover, and perform (cognitively and physically) in the time that follows. If you do consume alcohol, this episode walks through practical ways to reduce its potential impact by paying attention to what happens before, during, and after drinking.

Here is the relatively new probiotic supplement we mention towards the end of the episode.

Your physiology doesn't always follow what the textbooks say. In this episode, we sit down with Dr. Marco Altini (ultra runner, endurance coach, data scientist, and thinker at the intersection of physiology, technology, and performance). Marco opens up about the moment he realized that doing the same high-carb diet he recommended to himself for years wasn’t actually working as well as he thought. He walks us through how shifting to a periodized approach - changing fueling based on training demands rather than sticking to a fixed carb ratio - improved his fat oxidation, gut health, and performance markers in ways he hadn’t seen before. Marco grounds the discussion in real data, including how his substrate oxidation changed after adjusting his diet and why better metabolic flexibility matters for endurance athletes. Along the way, we tackle common misconceptions about high-carb diets, the link between GI distress and fueling strategy, and why testing beats guessing when you want to understand your own response to food and training.

What we cover in this episode:

• Why metabolic efficiency is not a single target, but a moving range
• How nutrition periodization can support training without wrecking your gut
• The overlooked connection between GI distress and everyday dietary patterns
• What Marco learned from tracking substrate oxidation instead of guessing
• How fat oxidation and VO₂-related metrics can change with nutrition shifts
• Why weight loss is not the same thing as improved performance
• The role of testing in understanding what your body actually responds to
• How to think critically about fueling without copying elite or influencer strategies

In this episode, Dina and Bob talk through a recent Triathlete magazine article outlining how some of the top professional athletes fueled at the Ironman World Championships in Nice and Kona this year. We review the carbohydrate intake ranges along with the fluid and sodium data and add context for what may explain the differences among the pros and why these strategies don’t always translate to age-group competition.
