You're Not Underperforming. You're Underfuelled.
You’re Not Underperforming, You’re Underfueled
This episode argues that many women are not failing at discipline, they are failing to eat enough for the life they are actually living. Didi breaks down how work, commuting, parenting, training, stress, and daily movement all raise energy needs far beyond gym time alone. She also explains why underfueling can show up even in weight stable bodies, and why carbs, micronutrients, and regular structure matter for energy, recovery, and mental health.
Key topics
- In this episode, Didi challenges the idea that women should base food intake only on body size or fat loss goals, rather than on the demands of their actual life.
- She explains that energy needs come from the full day, not just the hour in the gym, including steps, work, commuting, childcare, thinking, and stress.
- Didi argues that wanting to lose weight does not mean eating the smallest amount possible, and that an effective deficit should preserve training quality, recovery, and adherence.
- She calls out the myth that underfueling only affects underweight people, noting that low energy availability can happen at any body size.
- She says the body often gives warning signs first, including fatigue, feeling cold, irritability, poor recovery, reduced performance, and menstrual or mood changes.
- Didi reframes hunger as information, not failure, and says weekend overeating is often driven by weekday restriction rather than lack of willpower.
- She discusses how ADHD, executive dysfunction, appetite changes, medication wear-off, hyperfocus, and forgetting meals can make regular fueling harder.
- She distinguishes macronutrients from micronutrients, saying macros support body composition, while micronutrients, fibre, and variety support health.
- Didi highlights that even high protein intake can still mean a poor diet if it crowds out iron, calcium, vitamin D, iodine, essential fats, carbs, and plant variety.
- She closes with the idea that the question is not how little you can eat, but whether you are eating enough to support the life and version of yourself you are trying to build.
