Because few people tend to answer questions in this forum (other than Yours Truly, whose presence seems to effectively scare away some posters
) I'm going to suggest that in cases where you're looking from feedback from others, you may do better to post in another forum where others are apt to see your question and offer their feedback. Offhand, I'm inclined to think simply that some foods may not be available in plan friendly convenience forms (something our members in Australia can certainly vouch for) in which case you have to weigh the options available to you: use it fresh, not use it at all, or use what is available to you being aware it's not going to give you the best weight loss results.
I cannot comment on something from another weight loss source, simply say that if a food is listed in our materials, apparently testing showed that people still were able to experience satisfactory weight loss it as an occasional component of their diets. Perhaps the issue is that those who are medically restricted must follow even stricter guidelines than we do?
