Like Debra, I go back and forth with my thoughts about HAES and size acceptance, reconciling those with my efforts at weight loss (in her case, weight loss maintenance).
Sometimes it’s harder than other times. Case in point: this recent post from the official HAES blog.
I’ve got very little issue with the article itself (I think weight stigma in the health industry is a huge problem), but I do have an issue with this graphic at the end of the article:
Yeah, sure, that’s it. My only problem has been having to buy clothes one size bigger. NOT.
Anyways, I’m totally for health … at any size. For me right now (and at my age), that involves efforts to reduce my weight. Cause here’s a tip for all those HAES folks in their 20s, 30s, and 40s. What works for you when you’re younger may not necessarily work in your 50s or 60s.
And maybe it’s just in my head, but I don’t think that HAES and weight loss need to be mutually exclusive.
Update, 10/6: Linda Bacon clarifies the official HAES perspective:
[Y]ou can’t pursue HAES as long as your health model considers weight. … HAES works when and only when we disregard weight and focus instead on attaining the best possible health.
Weight Maven is written by Beth Mazur. Beth believes that obesity is more symptom than cause and that the real problem is our Western diet -- especially sugar, refined grains, and industrial oils. Beth writes about nutrition, ancestral health, & food policy. And cats! 
I agree with you that HAES and weight loss don’t need to be mutually exclusive. However, what do you think of the following statement to the 9/9 update to “Today’s annoying study” of Sept 7:
‘healthy’ overweight and obese people (male or female) have very little if any health risk from their extra weight and should probably be left alone (certainly not be encouraged to lose weight). No one has yet demonstrated any long-term benefit of weight loss in this ‘healthy’ (Stage 0) obese population and there is far more potential to do harm than good (especially, when the weight comes back, as it most likely will - often with a vengeance).
This is what the Fierce Fatties folks advocate.
In general I totally agree with that statement. A couple o’ comments. One, I’m not sure there have been any studies showing long-term benefit of weight loss in any obese pop, much less the ‘stage 0′ folks. In general, the benefit is really inferred from proxy measures (lower BP, better lipids, etc). So I’m sympathetic with the idea that weight loss, in and of itself, is not beneficial.
But … if excess weight represents poor eating behaviors as a result of a crappy diet (and/or other factors), and turning to a nutrient dense diet for health results in weight loss, then that should be okay too.
