I think it is your response to that poster that is the sort of reason the WLI are getting pushback though.
As I see it, they are an option, and for people who have very real health issues and plenty of reasons the weight loss is hard - and it CAN be complicated; I have good friends who have had weight battles and I am fully on their side that there wasn't an easy fix through traditional weight loss methods - I think they are a godsend.
However, not everybody's situation is the same, and for many people, especially with only a little to lose, diet and exercise can actually work and, as I see it, should be the first line of attack. It is the idea that that is now somehow outdated and ridiculous that I think people see as the dark side of the WLI.
I just think everyone should make their decisions based on their situation - and we can never really judge that from the outside.
It is the polarised positions - it is cheating, they are absolutely too dangerous regardless of the user's current obesity-related dangers vs they are essential and anyone who raises even the slightest misgiving is simply a jealous naysayer who has zero understanding of science - that are likely to lead to an unhealthy discussion around them.
The truth, as ever, is likely to sit somewhere in the middle: they can be useful in the right circumstances where clear benefit outweighs any misgivings.
But I don't think poo-pooing healthy diet and exercise is a reasonable standpoint.
