I've noticed that after I lost quite a bit of weight I'm much less tolerant of the cold than I used to be. I wonder if that is mostly from lost insulation or if there is a component where brown fat is being triggered and my body is sending a signal?
It would be remarkable if cooler room temperatures triggered higher caloric burning and did not increase appetite (that hasn't been shown one way or the other). I wonder if that would decrease home heating loads in the Winter and increase air conditioning loads in the Summer?
All of these studies achieved dietary intakes of cholesterol averaging above 800 mg per day. This is substantially higher than than recommendations to limit intake below 300 mg. Although this recommendation may curb the intake of other less healthy choices, it also does this for eggs, for which the evidence suggests is not necessary.
Considering that multiple lines of evidence, from a rich cultural history to long term observational studies to short term interventional studies on cardiovascular biomarkers suggest that eggs are healthy. Based on all of the data, I have no problem suggesting that up to 3 or 4 eggs per day is perfectly fine, and perhaps in many people even more. Though some short term research suggests that eggs may be beneficial in people with metabolic problems, observational data suggest that diabetics may benefit from a lower cholesterol intake, as they have an altered cholesterol metabolism. Thus, this is the only caveat I see at the moment.
Short term controlled studies have found that indeed consuming cholesterol increases serum cholesterol, but it is highly individual on to what extent, if any. And this itself should not be a reason to avoid eggs. When other markers of cardiovascular health are examined, they suggest that eggs may are either benign or beneficial. Triglycerides do not change, and LDL:HDL ratio does not change significantly, as both increase. Examining subfractions of these finds that eggs actually promote a less atherogenic LDL profile.
The research on satiation and subsequent calorie intake is extremely fascinating. There are not many interventions as simple as replacing dull, high carbohydrate foods with eggs for breakfast that may make significant long term differences in weight.
One last thing to emphasize is that the yolk must also be consumed for benefits, as the majority of the nutrients are contained there.
Ross Tucker is a solid science of sport guy - a Ph.D. in exercise physiology and someone who has added insight to the field. He has done fine work in the past year debunking the 10,000 hour myth that became entrenched in popular culture after Malcolm Gladwell popularized it (Gladwell has a compelling writing style and is a good storyteller, but his science is often way too shallow and incorrect)
Ross blogs about his experience in a debate with the originator of the 10,000 idea. It sounds like a frustrating time and reminds me of issues climate scientists have with the pseudoscience of climate change deniers or biologists (and scientists in general) have with pseudoscience that fights evolution and other core concepts of science.
David has announced the specifics for this year's Freedom to Connect conference. This is a very important get together focusing on Internet access and a variety of fascinating issues that mix society and technology.
Why go to something like TED when you can be part of something much deeper? You'll find similar spirits as well as people to disagree with, but all in a friendly atmosphere with great music at the intermissions.
May 21-22 in Washington DC ... and reduced rates for if you sign up in the next two weeks. If you care about these things and can get away it is one of the best conferences going - I would argue the best.
