I am not sure if we are doing a specific paleo diet here, but I think we're on to something similar.
My husband has had a heck of a time losing weight. He was in super shape during his athletic years (mountain biking, martial arts, rock climbing) and weighed in at about 135 lbs and 5'7." He is naturally small framed, and even when at the height of his strength (he never figured out how many pull-ups he could do because he got bored doing so many!) he was really wiry and small.
Now that he has a desk job and has to be in the office all day he'd gotten up to 165 lbs or so, which is right on the cusp of overweight for his height and frame. Despite the fact that he runs for an hour or so three or more times a week his weight has been climbing for the past few years, and nothing he has done has seemed to bring it down. We ate in a way that I considered pretty healthy: all organic, lots of fruit and veggies, non-homogenized dairy, only whole grains (but a lot of these), pasture-raised meat...
Last month he asked if I could cut out starches from his food. I am the main cook of the household and tend to do all the grocery shopping. He wanted to go off all grains, potatoes, and such. This was BIG for him, because in the past he has been extremely reluctant to make any diatary changes.
I was willing to try the no grain and low starch thing, and started adjusting my cooking. I have begun using a lot more meat and eggs. We've always eaten a good amount of vegetables, but I started putting a ton more in his lunch, especially raw. I've cut out almost all the starches and starches that he normally eats (he never had much of a sweet tooth to begin with, thank goodness). The amount of fats originally worried me, but the results have been really amazing!
In a little over one month, with no change in exercise habits (continuing with the running and the little indoor rock climbing we do), he lost 8 pounds, and a couple inches around the waist. He is using preciously unused belt holes, and his pants are becoming too big! He has had bowel issues as long as we can remember, and even those seem to be normalizing. I've kept him well supplied with food at work, and he says that he is never hungry anymore, and that his usual blood sugar issues (hypoglycemic) have not seemed to be as strong.
I'd like to get to know more about the Paleo diet, because it seems like that is along the lines of what we are doing. We do use a small amount of dairy in the form of yogurt and cheese, as well as a good deal of butter, and I'm not sure how that stands for a paleo diet. I know we are not 100% in line with it yet, and I would like to know more about it.
