Have you registered for the Paleo Summit – its being advertised as a virtual Paleo conference. I’ve signed up, it will be interesting to see how it turns out.

A look at breaking the exercise to eat cycle. Eating and Exercise are not morally loaded actions but so many treat them that way.

Realize that you do not need permission to eat. You don’t have to earn your calories. You’re a beautiful person worthy of eating just by virtue of existing. Even if you do nothing but sit on your butt, you have earned the right to eat and to eat food that is enjoyable.

Exercise is not punishment. You should find a way to move your body that you enjoy. While no exercise is 100% fun 100% of the time, I’m convinced everyone can find a way to be active that is challenging, fulfilling and mostly fun. If you hate running, please don’t run! (And to my readers who love running – you keep on running, I don’t mean you!) Dance, hike, bike or join a synchronized swim team (and then tell me how they get all that makeup to stay on in the pool!) but find something you love.

 

An interview with  female powerlifter, Jean Fry :

Of course! My most recent meet was about 6 weeks ago (at the Powerstation Pro-Am), marking my 4-yr anniversary at Westside. I squatted 415lbs and deadlifted 375lbs at a body-weight of 123lbs; I also scraped out a pro total with 1025lbs (despite having a terrible bench day). My best benches to date are 250lbs at a body-weight of 123lbs and 230lbs at a body-weight of 114lbs.

 

Mark Sisson looks at the need to eat brightly coloured vegetables and sulfur rich vegetables. While  artificial antioxidant supplementation continues to be shown as useless.

Stumptuous looks at the need to eat meat. Over at Hunt, Gather, Love – a review of Why Women Need Fat. Gnolls.org examines why humans became smarter rather than just more numerous.

More evidence that exercise doesn’t have to be time consuming, just hard – yes its interval training!

Not Just a Man looks at a couple of studies:

Activity levels affect bone density in women.

As expected, bone density by the BUA measurement increases noticeably with the increase in activity levels.  While VOS also increases, it doesn’t seem to be a significant movement so perhaps activity levels only really impact the structure of the bone rather than its elasticity and exact mineral content?

Strength training and adiposity in Women:

Moving over to the training group there is a much bigger reduction in body fat percentage with almost double the lean mass gains seen by the control group and a statistically significant reduction in fat mass when compared to the control group.  Despite the adherence drop-off in training during year two that was so evident in the strength measurements, the lean mass mostly remained with the trainees, although body fat started to return in year two.  Despite this, the body fat did return at a slower rate than the control group were putting it on, perhaps thanks to the additional muscle the trainees were carrying in year two.

Strength training has also been linked to better cancer survival rates. Exercise also seems to trigger stem cell growth in muscles, as well as just making you feel damn good

A look at the continually changing role of marriage in human society.

A study looks at the role of compression pants in recovery. They found a statistically significant advantage but at this point can only hypothesise as why.

Rob Wolff looks at how to carb-load.

Skeptic North calls for an end to funding of CAM* in education (*psuedoscience and superstition masquerading as health care).

Months of thinking – lots of links

Due to a multitude of life stress going on I’ve really feel behind on this site. So in an attempt to catch up I’m going to just link to all the stories that have caught my eye over the last few months.

Vitamin C supplementation may aid recovery from intense exercise in the cold. Is honey even honey any more? Why do we keep messing with our food.   Are our agricultural staples trying to kill us? A look at which nutrients are essential for healthy mitochondria. Can you eat too much liquorice? Yoghurt doesn’t work the way we thought. A look at the effect of a paleo diet on testosterone. The evolution of lactose tolerance and how to use it if you have it. An interview with Dr Loren CordainWholegrain pasta offers no benefit over refined pasta. A look at preparing traditional grains. Are eggs the answer to weightloss? Here’s seven more reasons to eat them.

Meat doesn’t rot in your colon – grains do. Another study shows that grass-fed red meat is healthier. A diet high in fat is not fattening. A ted talk on using diet to stop angiogenesis. And a diet high in carbohydrates is linked to cancer. So while low carb seems better for reducing cancer and heart disease, its best to keep it high in vegetables.

However, is it just a matter of  eating whole foods that’s more important than individual nutrients. The Perfect Health Diet offers a food apple guide, and lifehacker suggests how to begin eating ancestrally

Are you always aware of what you eat – a look at how your subconscious mind affects your diet. The link between  omega3  imbalances and depression and how increasing your omega3 levels can reduce inflammation and anxiety. How to balance your omega 6 vs omega 3 ratios. A guide to cravings and what your body might actually be needing.

Mark Sisson talks about the idea of gateway foods and helpfully provides a delicious sounding recipe for pumpkin pie. How about paleo egg-cupcakes? On the low-carb front – if you’re missing burgers how about a recipe for an oopsie bun. When the winter colds hit – here’s some suggestions for healthy comfort food. And now you’re inspired – here’s a big recipe roundup.

Letting children’s playground be fun results in less accidents then those awful safety playgrounds. A look at the differences of American-European values. Interesting how a respect for individual rights plays out when the people are women. Alas offers a simple primer to evaluate the anti-women’s health arguments. Another reason to damn the development of agriculture. Sam Harris looks at how to be safe in a world with a propensity for violence.

Weightlifting for women is starting to hit the mainstream. A guide to dynamic stretching. Does muscle really burn more calories? Its important to pay attention to muscle imbalances.  Is chocolate milk the best post-exercise drink? Exercising on an empty stomach may not be a good idea. Why cardio is not the best way to lose fat. How exercise can you become more sensitive to feeling full when eating. What ever you do – just stop sitting  down!

Cycling can be dangerous – the Florida Dept of Transport says riding 4-5 ft from curb, not wearing spandex, being a woman all cause cars to move further over in the lane when passing you. And its shown to be cheaper to build cycling infrastructure than not.

Seven ideas to improve your running, and how to improve your mileage.

Carbohydrates not Saturated fat biggest risk factor for Cardiovascular Disease

Filed under: Health and Nutrition — Tags: , , , , — Sceptically Me @ 23:54

Another study just published that showing the link between high glycemic  foods and heart disease, not saturated fat.

Abstract

The dietary intake of saturated fatty acids (SAFA) is associated with a modest increase in serum total cholesterol, but not with cardiovascular disease (CVD). Replacing dietary SAFA with carbohydrates (CHO), notably those with a high glycaemic index, is associated with an increase in CVD risk in observational cohorts, while replacing SAFA with polyunsaturated fatty acids (PUFA) is associated with reduced CVD risk. However, replacing a combination of SAFA and trans-fatty acids with n-6 PUFA (notably linoleic acid) in controlled trials showed no indication of benefit and a signal toward increased coronary heart disease risk, suggesting that n-3 PUFA may be responsible for the protective association between total PUFA and CVD. High CHO intakes stimulate hepatic SAFA synthesis and conservation of dietary SAFA . Hepatic de novo lipogenesis from CHO is also stimulated during eucaloric dietary substitution of SAFA by CHO with high glycaemic index in normo-insulinaemic subjects and during hypocaloric high-CHO÷low-fat diets in subjects with the metabolic syndrome. The accumulation of SAFA stimulates chronic systemic low-grade inflammation through its mimicking of bacterial lipopolysaccharides and÷or the induction of other pro-inflammatory stimuli. The resulting systemic low-grade inflammation promotes insulin resistance, reallocation of energy-rich substrates and atherogenic dyslipidaemia that concertedly give rise to increased CVD risk. We conclude that avoidance of SAFA accumulation by reducing the intake of CHO with high glycaemic index is more effective in the prevention of CVD than reducing SAFA intake per se.

Misguided Attempts to Help

Filed under: Health and Nutrition — Tags: , , , , , — Sceptically Me @ 17:50

Unhealthy food needs to be taxed more – but it needs to actually taking unhealthy food, not good basics like butter, full-fat milk, cream and especially not meat! Target processed food, target sugary and starchy foods! And of course, ban trans-fat! That’s one thing the Danes got right.

The government will consider introducing a “fat tax” to tackle Britain’s growing obesity levels, the prime minister, David Cameron, has said.

Cameron said drastic action was needed to prevent health costs soaring and life expectancy falling.

Under measures introduced in Denmark recently, a surcharge is being placed on foods that contain more than 2.3% saturated fat. The levy targets high-fat products such as butter, milk, cheese, pizza, meat, oil and processed food.
