I think that a major offsetting factor may be the utility derived from eating to excess and the opportunity cost of spending time in exercise.
Though, it probably makes sense to be healthy for individuals (benefits exceed costs), I would think the costs make it a much closer to the margin to be prioritizing mass interventions. Avoiding contracting malaria, for instance, is less likely to have significant personal costs, while providing immense benefits.
Sure, being healthy is a great thing to promote, but I suspect the significant costs involve this from approaching being a super effective cause area.
