Metabolic and physiologic improvements from consuming a paleolithic, hunter-gatherer type diet

Background:The contemporary American diet figures centrally in the pathogenesis of numerous chronic diseases-'diseases of civilization'. We investigated in humans whether a diet similar to that consumed by our preagricultural hunter-gatherer ancestors (that is, a paleolithic type diet) confers health benefits.

Methods:We performed an outpatient, metabolically controlled study, in nine nonobese sedentary healthy volunteers, ensuring no weight loss by daily weight. We compared the findings when the participants consumed their usual diet with those when they consumed a paleolithic type diet. The participants consumed their usual diet for 3 days, three ramp-up diets of increasing potassium and fiber for 7 days, then a paleolithic type diet comprising lean meat, fruits, vegetables and nuts, and excluding nonpaleolithic type foods, such as cereal grains, dairy or legumes, for 10 days. Outcomes included arterial blood pressure (BP); 24-h urine sodium and potassium excretion; plasma glucose and insulin areas under the curve (AUC) during a 2 h oral glucose tolerance test (OGTT); insulin sensitivity; plasma lipid concentrations; and brachial artery reactivity in response to ischemia.

Results:Compared with the baseline (usual) diet, we observed (a) significant reductions in BP associated with improved arterial distensibility (-3.1+/-2.9, P=0.01 and +0.19+/-0.23, P=0.05);(b) significant reduction in plasma insulin vs time AUC, during the OGTT (P=0.006); and (c) large significant reductions in total cholesterol, low-density lipoproteins (LDL) and triglycerides (-0.8+/-0.6 (P=0.007), -0.7+/-0.5 (P=0.003) and -0.3+/-0.3 (P=0.01) mmol/l respectively). In all these measured variables, either eight or all nine participants had identical directional responses when switched to paleolithic type diet, that is, near consistently improved status of circulatory, carbohydrate and lipid metabolism/physiology.

Conclusions:Even short-term consumption of a paleolithic type diet improves BP and glucose tolerance, decreases insulin secretion, increases insulin sensitivity and improves lipid profiles without weight loss in healthy sedentary humans.

Hope this will reassure Louis and people who still think they need lotsa carb to sustain activity

Well, this just shows that it's good for general health, nothing that proves anything about sports performance. I would still take some carbs for peri-workout nutrition and perhaps earlier part of the day. Used to be more disciplined, have been slacking a bit. Just had a lot of garlic naan yesterday and fried rice this afternoon hehe, not too "paleo". Tomorrow better get my ass kicked at 300!

Try taking some processed carb before workout 2moro, I'm sure you'll feel very high during the challenge.

Snickers bars and Coke here I come!

when i am done with the comp, and start the 300 intensively again, I want to prove that u dont really need carbs for 300.

Wah, your goal also always change leh...thought you wanted to go for max strength and mass gain with 300 on the side? Max strength and mass gain I personally feel you do need carbs.

max strength really need carbs? ok lah... maybe some broccoli and oats and sweet potato won't hurt.

BTW, when I say mass gain, I dont mean I want to be bui2. I would still like to have abs.

Well, just ask Derrick if he's on low carb, and that will be your answer

That's exactly what I have been saying. When carb's injested and insulin released, glucogon can't do its job of drawing energy from the cells thus a conflict of interest in energy expenditure, leading to poor performance and nausea. I tried once, I had chicken rice (very long ago) during a 5rds 400m + 15 Bodyweight DL and I almost puked and give up just into rd 2. Thats when I started to believe in paleo and zone

Wah, you can eat chicken rice during a circuit...chiu are champion multitasker!

Can demo tomorrow? 30min of brisk walk should be a lot of time to finish?

I meant before workout lah about 1.5 hour before.

i can second that.

don't take proccessed carbs before training. knn fucking lousy energy source

lol famous amos ftw man!

hihi kevin, when your gym open, the rates wad ah? i wan do crossfit. ahhaha

Everything's ready including the equiptment, just waiting for the right place. Sadly the Cage diddn't pull thru. The rates gotta depend on the rent, so I'm looking for a cheaper place so I can extend the low rates to everyone. Give me 1 more month bro, I try to get a nice place. I'll keep everyone updated, thanks for the support.

switch to liquid carbs - glucolin or ribena.
Obvious there is some truth in allow 1 hour for digestion before you start an intensive exercise.
