Of course, this is a valid point. Many people with serious weight problems suffer from low self-esteem and other emotional distresses, which often complicate their efforts to lose weight in the first place.

Still, it is plain to see that the continuing obesity crisis is not a sustainable situation. Throwing our hands up and walking away in resignation is not an option — too much is at stake here. There is no way that we will ever be able to provide affordable health care for everyone if the health of vast parts of the population continues to deteriorate at this pace. We won’t be able to dig ourselves out of this crisis, no matter what health care model we try to follow.

The necessary lifestyle changes will not happen without awareness and recognition of the consequences we will face if we continue on the current path. Unfortunately, the immediate forecast is not hopeful.
