How lean has she been previously? What was she used to maintaining, bf% wise, before her coach ****ed her up?
Carb cravings are common, I and many others get them, but its interesting that she's suffering as she's tapering off...it may have a lot more to do with the weight/fat loss than DNP per se.
Depending on her past, and her set/settling points specifically, there may be very little that you can do about this and mental discipline becomes the primary determinant of her success.
Even if it is due to DNP, my hunch is that NPY is involved and that is a tough little path to side step without experimenting with other drugs (how willing are you/she to do that?).
Some non-pharmaceutical suggestions that may or may not help:
- You can try manipulating her food choices (more fibre, lower caloric dense foods), playing with meal frequency (higher or lower, try both), depending on what times of the day she feels the most ravenous you can play around with nutrient timing, etc.
- Reducing the size of the dietary deficit by reintroducing some carbs is an obvious step to take but depends on how "fixed" her time frame to hit this goal is.
- How far away is she from her post-dnp refeed? You could increase the duration of the refeed, when it comes, so that it lasts 2-3 days at maintenance cals in order to allow her to get more carbs in (warning: I have no idea how good her post-carb satiety is and this may turn into a full binge).
- Taking a full diet break, a brief period of a few weeks eating at maintenance, post-dnp in order to help renormalize some metabolic stuff (again, may not be possible on a strict time frame).
Appetite suppression involves multiple pathways (that's why you don't a DNP equivalent for it in terms of efficacy) and if it does have to with NPY and/or genetic limits then she's in for a rough ride without extra drugs I'm afraid.
Even if she's willing to go the pharma route, it would involve a lot of experimenting to find the right choice (due to the multiple pathways involved) and I'm uncertain if she should go down this path (your a different story due to your experience and so on).
Carb cravings are one of the main reasons why people get poor results on DNP - not that any of them will openly admit that they pig out of course
