Association between estimated total daily energy expenditure and stage of amyotrophic lateral sclerosis

The present study suggests that TDEE decreases with progression of ALS, and patients consume insufficient energy compared with required intake at all stages, particularly at stage 3, suggesting that nutrition support should be started at least before stage 3. Additionally, among the five equations for TDEE, TDEE 2 could be the best for evaluating the nutritional status of patients with ALS.
