Well you haven't provided any answer options so answer options include things like mountain climbing. Mountain climbing involves multiple systems and functions over a long period, with moderate being something like hiking the same mountain.
Sheila should have desserts in small portions and increase activity levels. Not eating certain types of foods is no good, although for high-sugar/high-fat foods, moderation should always be practise. Increasing activity level prevents from accumulating fat and reduce the risks associated with high sugar foods, so this could be a great strategy for Sheila.
