Episode #142 of the BenGreenfieldFitness podcast. Ben opens with announcements (T‑shirt contest, book giveaway, VIP text club), then answers numerous listener questions on topics including post-exercise glycogen replenishment (study-based dosing and timing), recovery after quitting smoking, fasted exercise and muscle loss, distinguishing menopause from exercise-induced amenorrhea (hormone tests/FSH thresholds), saline vs. chlorine pools, training tips for triathlon/run/cycle, low‑oxalate diets and kidney stones, blood‑pressure meds and supplement interactions, D‑ribose dosing, and supplement quality. The episode concludes with a featured interview of Peter Shankman (HarO founder), who describes how he maintains fitness while traveling, his strength-focused training, simple travel equipment, use of technology (TrainingPeaks), and productivity hacks for swim/cycle/run.

Questions this episode answers

About 1.2 grams of carbohydrate per kilogram body weight per hour, continuing for up to ~5 hours (studies cited range 1–1.8 g/kg and dosing every 15–60 minutes).

Approximately 400 carbohydrate calories per hour (≈96 g carbohydrate/hr), totaling roughly 2,000 carbohydrate calories over 5 hours.

Include protein with carbohydrates at about a 3:1 or 4:1 carbohydrate:protein ratio.

FSH around 10–12 suggests ovarian decline/entering menopause; FSH around 30–40 or higher typically indicates ovarian failure/menopause.

Supplemental D‑ribose doses mentioned range from about 2 g up to 10 g depending on body size and exercise load.
