I've been a vegan for over ten years (and a strict vegetarian for the ten years before that)...and I'm a runner, a sports player, and my vitamin B12 and calcium levels are fine. I think you did little research into these actual diets (although mine is a lifestye...a permanent, ecofriendly, philosophical lifestyle).
I did some research in two eating disorder clinics last year -- this article is very similar to the way the dietitians who worked there thought. I knew more about nutrition than them and foods they've never heard of. I found that extremely discouraging.

This article is one example of why I'll never subscribe to EatingWell again. The Paleo Diet is not a low carb diet. It focuses on local lean meats, fresh vegetables and fruits, and natural oils. It turns out that grains and potatoes have antinutrient compounds in them that inhibit the absorption of vitamins and minerals. Do some research and you will find this out. And kale has way more bioavailable calcium than milk.

One of the best things about Paleo is that it is a way of eating you can keep up forever. My wife and I are a year in and have no temptations to return to the low fat, high carb, sickness inducing diet this writer encourages. I love how these people bash Paleo and sound like idiots when they start spouting out nothing more than false information. Keep eating low fat and keep getting sick.

There is an error in your Dukan Diet information. Low-fat dairy (yogurt, cottage cheese, skim milk) are allowed in all four phases. Only cheese is restricted until the consolidation phase. And Oat Bran is required in all four phases, so there are some carbs, even from the beginning.

"Paleo: What’s missing?
Dairy, which is how most of us get our calcium and vitamin D. The Paleo Diet is also low in carbohydrates—and there’s research that shows limiting or eliminating carbs impacts your memory and your mood"
Please don't make claims to elusive studies without references to the research/ peer reviewed article, it's misleading.

I have been on the Paleo plan for about 7 months and have never felt better. Not only have I dropped 20 pounds, but my Cholesterol is down 30 points and have more energy and need less sleep. No more bloated feeling or constipation. Yes, it is a lifestyle, one that supports REAL FOOD from local farms. It isn't difficult once you get all of that junk out of your house. Just plan to shop on the perimeter of your grocery store (produce and meats) and find as many farmer's markets as possible. I am never going back! Life in the Paleo world is good!

The paelo diet is fine. Just because we're not eating a billion grams of carbs per day in the form of wheat flour (white or whole, doesn't matter, look at the research against eating wheat), grains, sugar etc means we're not getting any carbs at all? So the vegetables and fruit that paleo followers eat have no carbs, or, realistically, enough carbs (naturally) to sustain a caveman (which we still are, agriculture has only been going 10, 000 years or so? So how are our bodies going to evolve that quickly in 10,000 years, just because our eating habits have changed drastically with agriculture/mass production doesnt mean it's a healthy progression, at all. Look at all the new cases of gluten insensitivity and intolerance.) Who wouldnt feel good on a paleo diet? Fruit, meat, fish, eggs, veg. Clean, natural eating. No chemicals. Refined sugar is unnatural and therefore terrible for humans. Calcium & vitamin D are easily obtained through other non dairy sources. And dairy is terrible for you too. Suprises me a dietitian would write such uninformed drivel.

People don't need dairy. You can get calcium from many green vegetables, even more than in dairy. -_-

Paleo Diet. Vitamin K is in saturated fat on your meats, and you get calcium from your Greens! This nutritionist needs to do some studying so they can give out proper advice.

I have been on a paleo-like diet for the past 8 months and have lost over 60 pounds. I restricted my calorie intake to between 700-1000. It consisted of two 4 oz portions of quality protein, two servings of vegetables, fruit and nuts. The restricted calorie intake is difficult to maintain, and I sometimes have a slightly larger portion of protein or, more commonly, more fruit and nuts. After the first 15 pounds or so, my blood sugar was normal and I got off all of my Type II diabetes meds. My last A1C was 5.7. My physician, who has been trying to get me to lose weight for years, is more than encouraging. This diet is certainly not for everyone, but if you have been on a high-carb/low-fat diet as I have been on for years and still don't lose weight and have Type II, it is worth a shot.
