You can hit your daily calories and still wreck your hormones…
In female endurance athletes, underfueling within the day — even if total intake is “enough” — is linked to:
↓ Estrogen
↓ Resting metabolic rate
↑ Cortisol
↓ T3 (thyroid hormone)
More hours in an energy deficit = more hormonal disruption.
The takeaway? It’s not just how much you eat — it’s when you eat.
If you’re skipping fuel around training and “making up for it” later, your body still experiences stress.
👉 Fuel before, during, and after training to support hormones, recovery, and performance.
Fuel smarter, not just more ✌🏼
