I agree.....as long as there is some effort. Generally speaking the majority of AS use is used in conjunction with a strength training regiment and/or cardio. If the user's sole purpose is to lose weight with no routine IMO they are not using to their potential.
In this case she has been there before....15%...so she has proven to herself that she has the motivation and discipline to achieve her goal without AS for 'weight loss'. Granted that age may play a factor in achieving her goal again(please take no offense crcfitmom) but with all factors involved i.e strength training, cardio, and probably most important diet she can reach it again.
