I'm coming from Seasoned Advice SE since I voted to flag something as off-topic there because the question was asking for dietary and nutrition advice.
Question here - Are overnight oats good for breakfast with their high carbohydrate content?
Before sending the OP here, I checked the community rules and it says:
questions about cooking, nutrition and diets that are not directly connected to medical treatments (see Cooking.SE (Seasoned Advice) for that)
This doesn't match the Seasoned Advice SE community scope, as nutrition and diets can be considered off-topic per the following definition from the community scope:
General health and diet issue (e.g. "Is cauliflower healthy?")
According to the standard note when there is a question requesting nutrition, diet and other questions that border on medical / health advice:
"Questions on nutrition or requests for medical advice are off-topic here; you should contact a qualified medical professional instead."
Seasoned Advice only handles questions related to substitutions when the restrictions and boundaries were already established by medical professionals / nutritionists / dieticians or when the dietary restriction is not health related. (E.g. "I'm lactose intolerant, how can I substitute cream in X recipe?" or "What's a vegan alternative to gelatin in Y recipe?")
TL, DR: How can we ensure that both communities have matching scope description so questions don't get moved from one SE to another (i.e. question gets moved from here to Seasoned Advice because it is not connected to medical treatments, and then gets closed or moved from Seasoned Advice because it is considered nutrition / diet health advice)
