Ask Me Anything: Fat Intake, Soy Protein, Bone Healing & Post-Workout Headaches
Feb 10, 2026
Natalie Rizzo, MS, RD

In this mailbag episode, I answer your real nutrition questions about fueling an active, plant-based lifestyle. We cover how much fat is too little (or too much) for athletes, nutrition tips for perimenopausal women with Hashimoto’s, how to support bone healing after a fracture on a vegetarian diet, and whether relying on soy protein is healthy. Plus, I break down why you might be getting headaches and feeling awful after long endurance workouts—and exactly how to fix it with smarter fueling and electrolytes. If you’re a runner or cyclist trying to feel stronger, recover faster, and stop underfueling, this episode is for you.

Leave your questions for the next mailbag episode here!
