The coach won't answer something. Why?

Gretl's coach declines a specific set of things and will keep declining them however the question is put. It won't plan or price out a day below your calorie floor, won't design fasting or meal-skipping to make up for eating, won't treat exercise as a way to cancel food, won't give any method of purging or compensating, and won't tell you what you ought to weigh. Framing it as a hypothetical, as a question for a friend, or as something you're doing under professional supervision doesn't change the answer.

Everything else it does normally — estimating a restaurant meal, telling you where a drink lands you, being honest when a week went over. The limits are narrow on purpose; a coach that hedges everything is one you'd stop telling the truth to.
