One possible topic, which I may be reading in since it's on my mind, is the well-known "problem" with sticking with lower carb diets. I've been ruminating a post on the topic myself, but the core is that it comes down to two basic problems: One, willpower, since we're surrounded by terrible, yet yummy food, all the time, and two, flavor. It is occasionally mumbled, instead of yelled loudly as it should be, that if you want to eat healthy on the long term it isn't just a matter of cutting out something, you need to be
happy with the food. And in particular, "The Standard American Diet - carbohydrates" isn't a very pleasing diet. It's very easy for it to become monotonous and feel restrictive.
But I'd submit that's an indictment against the standard diet, not the "- carbs". It's taken me a while to work out how to deal with the correct diet longterm, but it has involved using a lot more oils (sesame, olive, etc), more butter, more oriental ingredients, and learning a lot more about French cooking. And you have to erase the last vestiges of the false idea that fat is bad, and realize that low-fat is bad and is the fad diet, and it should be entirely stomped out of your dietary plans. Now I don't have problems eating properly for years without backsliding; as tempting as the carbs can be, they just aren't as good as what I'm making myself. They're a hollow pleasure.
