I think the core idea in preventing body shaming is that no matter how healthy an individual can be, there are some things about your body that can never really be changed. Someone's "healthy weight" can look dramatically different on one person compared to another. You might naturally build up more fat in your legs than anywhere else, so even if you're slightly overweight, you become insecure because your legs look obese to you. The idea is to accept these things that can't be changed or aren't necessarily important to be changed. I believe there are even some studies now that indicate a possible positive effect in living at your "happy weight" instead of your "healthy weight". This "happy weight" isn't necessarily being obese, but factors in a weight that is comfortable enough for you to live your life the way you'd like to live it.
I think the issue with many people that preach against body-shaming is that they see it as an all-inclusive deal. While I'm not sure it's actually dangerous to actively accept various body types, I do think that it's important to stress that all of us can benefit from accepting who we are before realizing the benefits of improving. Striving toward a perfect self--physical or otherwise--can be dangerous because it's an insatiable desire. That all being said, I think that preventing body shaming is a good thing because it pushes the idea of accepting yourself even though you're different.
People, and girls especially, get caught up in wishing they looked like someone else. It prevents them from living their lives with the mindset they strive to have. I'll tell you right now that yeah I might be overweight and slightly crooked teeth and can't grow a mustache for shit, but even if I got into P90X shape, got invisalign, and took rogaine for my upper lip, I still wouldn't look like as Ryan Gosling. The core's self acceptance. Learn to accept yourself. Then the rest becomes easier.
