“…This absence of post-exercise modification of the EI derived from each macronutrient remains difficult to interpret due to limited and contradictive results in this population [11,18,27,28]. Our results regarding appetite feelings confirm once more the previously described “uncoupling effect” of acute exercise on appetite sensations and EI [29], since hunger, satiety or prospective food consumption were not modified by exercise in either lean or obese adolescents.…”

Reduced neural responses to food cues might contribute to the anorexigenic effect of acute exercise observed in obese but not lean adolescents

Acute exercise has been found to reduce subsequent energy intake in obese adolescents. Although it has been suggested that some neural pathways are involved in this post-exercise energy intake regulation, it remains unknown whether the post-exercise attentional response to food cues differs as a function of weight status. We hypothesize that there will be a reduction in the neural response to food cues as a result of exercise in obese adolescents, but not in their lean counterparts. Fourteen obese and 14 lean adolescent boys (12–15 years) were randomized (within-subjects design) to remain seated (CON) or to exercise 45 minutes at 65% of their maximal capacities (EX). After the exercise or sitting period, the adolescents' cognitive engagement in the processing of food vs. non-food cues was assessed during an attentional computer-based task with electroencephalography (EEG) recording. An ad libitum lunch meal was offered and appetite feelings were assessed (visual analog scales). There was no main effect of condition on energy intake in lean subjects, but obese adolescents ate significantly less following EX compared with CON (P < .05). There was no effect of condition or stimulus type (food vs. non-food) on the EEG-recorded amplitude of the P3b component in lean adolescents. However, the response to food cues was significantly reduced compared with non-food stimuli after exercise in obese participants (P < .01). Following EX, but not CON, total body weight, body mass index, and fat mass were inversely correlated with the EEG response to food–non-food stimuli (all P < .05). However, this response was not associated with ad libitum EI (both P > .1). Acute exercise favors decreased neural response to food cues compared with non-food cues in obese but not lean adolescents, suggesting differential effects of exercise on the neural processing of food cues based on weight status.

“…Indeed, when considering obese children and adolescents separately, the results are much more ambiguous, with one study showing increased intake (8), 5 showing a decrease (9,(24)(25)(26)31), and 7 showing no difference (8,25,26,(28)(29)(30). Although our meta-analysis approaches found no significant 325 effect of acute exercise in lean youth, it shows significantly reduced post-exercise food ingestion in obese ( Figure 2B).…”

“…However, the systematic review indicated that children and adolescents do not alter the macronutrient composition of their meal in response to acute exercise (9, 22, 24-26, 28, 30). Only 2 reported a change in fat (23,31) or protein and CHO (31).…”

“…Indeed, the meal type and exercise to meal interval also varied. Although all the included 305 studies proposed ad libitum buffet-type meal, the time interval between the exercise bout and the meal varied from 30 minutes (9,20,(22)(23)(24)(25)(26)(28)(29)(30)(31) to 80 minutes (7). Difference in timing between the exercise and the subsequent meal was shown to influence EI (32).…”

“…The present paper systematically reviewed fourteen original publications that questioned the effect 295 of acute exercise on subsequent energy intake in children and adolescents, with lean participants taking part in 9 of these studies (7-9, 20-23, 29, 30) where 9 included overweight/obese participants (8,9,(24)(25)(26)(28)(29)(30)(31). Although cycling was the most common exercise mode, there was variability in the exercise modalities between the selected studies.…”

Aim. This review aims to determine if acute exercise affects subsequent energy and macronutrients intake in obese and non-obese children and adolescents. January 2015 and December 2015 for studies reporting 40 energy and/or macronutrients intake immediately after an acute exercise and control condition, in children and adolescents. From the initial 118 references found, 14 were included for subsequent analysis after screening representing 31 acute exercise conditions that varied in intensity, duration and modality. Methods. Databases were searched betweenResults. One study found increased energy intake after exercise, seven decreased and 23 revealed no 45 change. The meta-analysis revealed a significant effect of acute exercise on intake in obese but not in lean youth by a mean difference of -0.430 (95% CI = -0.703 to -0.157, p=0.002) displaying low heterogeneity (I 2 = 0.000; Q = 5.875; df = 9, p=0.752). The analysis showed that intense exercise only reduces intake in obese children (no intensity effect in lean). Unchanged macronutrients intake was reported in nine studies as opposed to three which found modified lipids, protein and/or 50 carbohydrate intake. Conclusion.While acute exercise does not affect energy intake in lean, it appears to reduced food intake in obese youth when intense, without altering the macronutrients composition of the meal.
