Few months back, i started on a low carb diet, high quality fat, high protein, even taking whey ect, and wow my lean muscle mass is much better, i haven't lost much weight, as i lift weights, but i lost alot of fat, i look lean all over my body and face. I'm always full, i eat all i want, and before that i was eating lots of carbs, and at that time i had to watch what i ate, and still couldn't get the results i am now, so i'm a believer thanks to my results which i started the low carb after reading one of your posts, so i want to thank you for sharing your personal story.
1) High-fat, energy dense food -- meat -- has always been around. But, high-fat (or low-fat) meat doesn't affect insulin much.
With this part, I agree. But, for the most part, it's not fat or protein that has lead to the obesity epidemic in the States, it is carbs. And mostly, grains and fructose. Anyone following the food pyramid is doomed to be overweight.
thats not true either... the obsesity epidemic is rooted mainly in 3 things: 1) extremely energy dense food. satiety is based on volume... foods with huge amounts of energy and low volume make it easy to achieve caloric excess. 2) decrease in activity / increase in sedentary jobs 3) wealth increasing portion size
2) Far too many people lead active lives, yet cannot keep off the body fat. My last six martial arts instructors, all under 45, are great examples. Dr. Davis is another example a few posts above (I linked to his most recent blog entry). Exercise is significantly overrated as a tactic to maintain low body fat -- unless you exercise at athletic and pro levels. I barely exercise at all -- body fat = 10%, exactly where I want it to be.
3) People cannot eat large portions of a low-carb meal. This has been shown in numerous studies. When we in the USA are served in restaurants, yes we get large portions. Note that the bulk of what we're served is cheap starches and grains.
Nice to hear you've head success. I've heard the same results from literally dozens of people in my industry, where I'm been preaching a paleo diet for over two years. In general, people report these benefits:
o Significant reduction of body fat.
o Significant reduction in daily hunger.
o Elimination of energy lows during the day.
o Dramatically improved blood markers (I always have people test: CR-P, Lp(a), Triglycerides, HDL, and vit D)
And, like you, if people life weights, they grow muscle on this diet, and they realize that all that BS carb-loading is totally unnecessary.
The hardest part of the paleo diet is breaking the grain addiction. But, this is easier if you can mentally reposition grains in your mind, and think of them as just cheap, nutritionally vacant filler foods, used to feed the unknowing masses bulk calories. Do you really want to be a part of that herd? Of course not.
