Why you really can't outrun your fork.

Hat-tip to Yoni Freedhoff.

See Effect of school-based physical activity interventions on body mass index in children: a meta-analysis.
"Meta-analysis showed that BMI did not improve with physical activity interventions (weighted mean difference -0.05 kg/m², 95% confidence interval -0.19 to 0.10). We found no consistent changes in other measures of body composition."

Some people believe that if going to the gym isn't making them lose weight, they're not exercising hard enough. Chronically over-exercising can chronically raise serum cortisol, which makes the kidneys retain water, causing a stall in weight-loss, as well as causing raised fasting blood glucose, irritability, poor memory and a slower metabolic rate, due to the reduced conversion of thyroxine into tri-iodothyronine.

Don't over-exercise!

A healthy body weight is made in the kitchen, not the gym. Buy produce, cook it and eat it!

Although I totally support the use of low-carbohydrate/calorie diets for people with insulin resistance or Type 2 diabetes, now that I'm no longer insulin resistant, I can eat natural carbohydrates, without any problems.

A medium-sized (orange-fleshed) Sweet Potato takes only 4 minutes to bake in its jacket in a 700W microwave oven. The flesh is moist & sweet, unlike that of a Yam or potato.

I eat the whole thing, including the jacket. It's very filling and I'm still able to lose weight. For active and insulin sensitive people, a Kitavan-style diet is absolutely fine.

Sunday Smörgåsbord: liberty, the internet, worry, health & Lyle McDonald.

Five items this time, not necessarily related.

From http://en.wikipedia.org/wiki/Smörgåsbord

By liberty, I mean personal liberty. I believe that individuals should be free to do whatever they want, provided that they don't harm another individual. However, collections of individuals should not be free to do whatever they want, as collections of individuals (i.e. businesses) usually try to profit from individuals, so the welfare of the individual isn't of importance. Businesses obviously don't want to instantly kill their customers, as that's obvious and will probably get them sued. However, "killing them softly" isn't obvious!

In the EC, just about everything has a CE kite-mark in order that it may be sold in the EC. Standards include EMC (Electro-Magnetic Compatibility) to ensure that:-
a) Devices don't emit excessive levels of RF "radiation", which may interfere with other devices.
b) Devices don't respond to excessive levels of RF "radiation", which may interfere with their operation.
I put "radiation" in quotes, as it's TEM (Transverse Electro-Magnetic) radiation i.e. Radio Waves.

In the US, who knows?

This is about "Smart Meters" - again! I've recently seen a surge in Facebook statuses about Smart Meters. I posted a technical article about these devices in Smart meters. Even after I posted a link on Facebook to my article, links to alarmist pages still appeared. The latest one is The Great “Smart Meters” Hoax. Electromagnetic Fields Are Real And Dangerous To Our Health, where Sam Milham, MD, MPH epidemiologist & researcher tells us how things really are.

Unfortunately, he's talking shite. The problem with people talking alarmist shite on the internet is that people who read alarmist internet shite and who are ignorant of the subject, believe it! This causes Fear, Uncertainty & Doubt (FUD), which in turn causes chronic worry. Chronic worry causes chronic hypercortisolaemia, which isn't good. A placebo (e.g. wrapping aluminium foil around your Smart Meter or paying for a "proper" solution to the non-existent problem) alleviates the chronic worry, which improves health.

I don't know about US Smart Meters. For all I know, some eejit has designed them to transmit 1,000W of RF (I'm just being silly), to get an outdoor range of >100miles. As these devices are designed for short-range communication, they probably transmit up to 100mW (about the same power level as WiFi) to get an outdoor range of ~150m. 1mW is one thousandth of a Watt. Transmitting more power than is necessary increases the probability of interference to other electronic devices.

100mW is a lot lower than the power transmitted by mobile phones (up to 2,000mW for the 850/900MHz Vodafone/O2 network), which need to be able to reliably communicate with the nearest mast, which may be miles away. As mobile phones constantly transmit occasional bursts of RF (to let the network know that they are on) and they are either in a pocket or are held against the ear/in front of the face to make/receive calls etc (while transmitting regular bursts of RF) and they are safe to use, how can a Smart Meter which is transmitting a much lower power level at a much greater separation be harmful? It can't.

With WiFi, Equivalent isotropically radiated power (EIRP) in the EU is limited to 100mW. Dunno about the US. Bluetooth is very-low-power (~1mW for Class 3 devices).

So stop worrying! Chronic worry (also, reading alarmist internet shite) is bad for your health.

Finally, I noticed that Evelyn Kocur "liked" an article that I'd read and completely forgotten about. It's Evidence From the Metabolic Ward: 1.6-2.4g/kg Protein Turn Short Term Weight Loss Intervention into a Fat Loss Diet. Interestingly, the protein intake for optimum body recomposition is 1.6-2.4g/kg LBM. This is equivalent to ~1g/lb LBM, which is the protein recommendation given by Lyle McDonald in his Rapid Fat Loss Handbook. Yup, Lyle was right all along. That amount of protein isn't bad for the kidneys (even 50% more protein than that, isn't bad for the kidneys).

Resistance is useless!

...said the Vogon guard. If that means nothing to you, watch this...


You probably know all about Insulin Resistance (IR) if you've read my blog for some time, as I may have mentioned it once or twice ;-) There's also Leptin Resistance (LR) in the brain, which reduces the amount of appetite suppression that leptin is supposed to produce. Robb Wolf's just written about Adrenaline Resistance (AR?) and chronically-high serum cortisol seems to induce Cortisol Resistance (CR?) in the hippocampus, resulting in poor short-term memory.

When the level of "X" in the blood is low most of the time, "X" receptors in the body up-regulate, so when the level of "X" in the blood goes high, it has an effect. When the level of "X" in the blood is high all of the time, "X" receptors in the body down-regulate, so when the level of "X" in the blood goes higher, it has a reduced effect.

The above suggests that regularly "grazing" on food is not a good idea, as this results in a fairly constant slightly elevated serum insulin level. Eating a meal, not eating for a few hours then eating another meal results in high serum insulin while the meal is being absorbed and low serum insulin for the rest of the time.
