Oh, I get you now. Thinking of grooming, etc, I thought you meant short breaks, not a few hours at least. Re IR probs, yes, it's excess calories that are one big part of the problem, so restricting those calories for a substantial portion of the day(pref day & allow grazing at night when less sugars in grass) is helpful.
BTW, for those doing that, probably stating the obvious, but it's important to ensure the horse has some hay or such in that time, not go hungry.
