By: Dr. Sharma In kids, this disorder is often characterized by substantial hyperactivity, which would be expected to burn more calories. But what about the impact of ADHD on resting energy expenditure (REE) and the thermogenic effect of food (together accounting for about 60% if not more of the daily calories burnt)? This question was addressed by his colleague Thomas Mueller and other researchers from the University of Alberta in a paper just published online in Eating and Weight Disorders. Mueller and his team studied 12 pre-pubertal boys with untreated ADHD of the hyperactive- On average, REE was 6.5 kcal/kg fat free mass/day higher in the ADHD compared to the control group. However, there was no difference in the thermogenic effect of food between groups. Neither age nor restlessness explained the differences in REE. Despite the higher REE (and likely higher activity energy expenditiure due to the innate restlessness that comes with this condition), boys with ADHD had similar BMI levels compared to non-ADHD reference groups. Thus, this paper shows that despite notably greater energy expenditure, ADHD kids are not generally leaner, clearly suggesting that they manage to make up for their greater energy needs through higher caloric intake. One may well speculate that as these kids become older and their REEs (and activity expenditures?) How and why REE is elevated in ADHD clearly deserves further study. He would certainly appreciate hearing from any of his readers, who have experience with the ingestive behaviour of ADHD kids.
