Exercise is inherently linked to less food intake, possible related to less responsiveness to food cues (as behaviours do not change).
In otherwise healthy normal weight males, running for an hour on a treadmill at 70% VO2 max compared to either fasted or after a standardized test meal (30% daily energy intake and mostly carbohydrate) noted that fed exercise suppressed appetite to a greater degree than fasted (both more effective than control) but there was no significant differences in whole-day food intake.
Dammit. There’s certainly a risk in “reward” eating after exercising through fasting. But part of my motivation for exercising while fasting was about poor timing – too little time to fuel before doing something, which could make things uncomfortable and regurgitated. It’s up to you to figure what works for you, just do it for the right reasons.
