Train Smart: Fuel & Recovery for Women

Women Overtraining, Fuelling, Recovery & Avoiding Burnout

A practical guide to protecting health while improving performance

Training can be a brilliant tool for strength, confidence and wellbeing — but if exercise demands aren’t matched with enough fuel, rest and recovery, the body can start to struggle. In women, this may show up as low energy, poor sleep, frequent illness, injuries, or changes to the menstrual cycle.

When training exceeds fuelling and recovery

RED-S (Relative Energy Deficiency in Sport)

RED-S can occur when energy intake isn’t enough to cover both training and the body’s essential functions. It may affect menstrual function, hormones, immunity, bone health, mood and performance. (1)

Common red flags include:

• Period changes (irregular, missed, or noticeably lighter)
• Persistent fatigue, low mood, or reduced performance
• Repeated injuries (especially stress fractures) or frequent illness

Bone health matters

Low energy availability and hormonal disruption (including lower oestrogen) can reduce bone mineral density over time, increasing stress fracture risk now and potentially osteoporosis risk later. Adequate energy intake and nutrients such as calcium and vitamin D support long-term resilience. (1)

Overtraining and total stress load

Overtraining syndrome can develop when training stress continues without enough recovery. Key signs include fatigue, sleep disruption, mood changes and performance dips. It’s also worth remembering that the body doesn’t separate “training stress” from “life stress” — work pressure, poor sleep and under-eating can add to the load.

How to support performance (without burning out)

1) Eat enough overall

The foundation is enough energy to match your training demands. If you’re under-fuelling, performance and recovery can suffer even if food choices are “healthy.” (1)

2) Balance the basics: carbs, protein and fats

• Carbohydrates support training quality and help restore muscle glycogen (e.g., oats, rice, potatoes, fruit). (5)
• Protein supports repair and adaptation. A commonly cited range for athletes is around 1.3–2.0 g/kg/day, depending on training intensity and goals. (2)
• Fats support hormones, immunity and overall health — very low-fat approaches can be unhelpful for many active women. (1)

Menstrual cycle note: Some women experience GI symptoms around menstruation, which can affect food tolerance. If heavier meals feel difficult at certain times, lighter options (e.g., eggs, yogurt, smoothies) may be more practical. (3)

3) Time your fuel (simple version)

• Pre-training: a small carb-based snack/meal can support session quality.
• Post-training: aim for carbs + protein to support the “4Rs” of recovery: rehydrate, refuel, repair, rest. (4)

4) Hydration & electrolytes

For shorter sessions, water is usually enough. For longer or hotter sessions, you may benefit from fluids containing electrolytes and carbohydrates. Hydration needs vary by sweat rate, intensity and conditions. (5)

Over-drinking plain water during prolonged exercise without replacing sodium can increase the risk of exercise-associated hyponatremia, so “more” isn’t always better. (6)

5) Supplements: food first

Supplements can help in specific situations, but they don’t replace a balanced diet. If you compete in sport, choose products that are third-party tested (e.g., Informed-Sport style testing) to reduce contamination risk. (1)

Key takeaway

Strong performance is built from training + fuelling + recovery. If you’re noticing persistent fatigue, repeated injuries, frequent illness, or menstrual cycle changes, it’s worth taking it seriously and seeking support early.
