- Abstract:
- Background: To address the increasing rates of overweight and obesity, exercise is often promoted. However, the ability of exercise alone to produce weight loss is smaller than expected due to compensatory eating, which is defined as increased post-exercise food intake. The purpose of the present study was to assess whether exercise intensity differentially impact post-exercise food intake. › Methods: Twenty-five healthy, regularly exercising and normal-weight participants (26.5 ± 7.4 years old; 21.7 ± 1.7 kg/m2; 44% female) completed an exercise bout (5km run) at either high intensity (HIE) or moderate intensity (MIE) in randomized order. Participants completed a survey to assess hypothetical food choices before (pre), immediately after (post) and 30 minutes after exercising (post30). Preferred hypothetical food amount preference and intertemporal preferences (immediate vs. delayed consumption) were analyzed using electronic questionnaires including different food types varying in palatability and energy density, presented as visual food cues. › Results: When compared with pre, preferred food amount for immediate consumption increased significantly post-exercise only in MIE (179 ± 71 vs. 140 ± 65 kcal per item, p=0,005) but not in HIE (156 ± 74 vs. 145 ± 54 kcal per item, p=0,532). As a result, the increase in preferred food amount over the course of the exercise bout was significantly greater in MIE (per item) when compared to HIE (+39 ± 58 vs. +11 ± 66 kcal per item, p=0,029). At post30, selected food amount preference was greater than pre in both conditions (HIE: 223 ± 79 kcal; MIE: 223 ± 83 kcal; both p<0,01). The choice for immediate consumption increased in both conditions over time from pre to post (p<0,021) and post30 (p<0,01), but there were no significant differences in intertemporal preference between HIE and MIE at any time point. › Conclusion: Our results suggest that high intensity exercise might be less vulnerable to a compensatory eating. However, this reduction in food intake seems to exist only for a short period in the immediate post-exercise state. Future studies need to determine whether these differences between exercise intensities can improve the efficacy of exercise as a weight loss intervention.
