Can MY FOODBOOK help with fatigue?

Whether MY FOODBOOK can help with fatigue is not supported by the available context. Fatigue is a complex symptom with many causes—poor sleep, stress, nutrient deficiencies, or underlying medical conditions. The DNA tests mentioned in the context (e.g., WeightLoss SLIM, APOA5, VDR) focus on metabolism or risk markers, not fatigue. Even if a test analyzed genes like COMT or BDNF, effect sizes are small and insufficient to explain or treat fatigue. The evidence for such tests is mostly rated as marketing or unclear. Without clinical validation and without addressing lifestyle factors, a DNA test for fatigue is not recommended. A medical evaluation remains essential.
