Diet soda gets the closest attention here, and the post aims at people with type two diabetes who drink it all day without thinking. The argument stays specific rather than general, and it is the piece most likely to change what somebody does that afternoon.
David Duncan writes as a pastor and never separates that from the rest. A post on working from home lists five reasons and puts nobody telling you what to do at the top, and he is cheerful about writing it once so he can send the link instead of answering again.
His review of a hormone based diet is enthusiastic and acknowledges the approach is controversial without really engaging with why. That is a medical question and belongs with a doctor rather than with a review.
Family posts and celebrity news pieces sit alongside those.
Read the diet drinks post if that is your habit, and take the diet review to somebody qualified before you act on it.
