I lost 40 pounds in the last year and it was mostly by balancing my meals and running. I would eat closer to 2000 calories a day and I would try to eat more proteins through food. This mean.. no shakes or anything that I had to buy specifically for that. So I would buy a lot of chicken breast and eat a lot of chicken breast. When I calculated how much protein/carbs/fat I was eating and compared it to what people suggested, I quickly realised that my diet usually consisted in a lot of carbs, a bit of protein and a bit of fat. It seems that everything you buy these days are really high in carbs and low on everything else.

I blame the fat-free movement greatly for this. Nothing has fat anymore and we need some of the good fats if we want to eat calories that aren't carbs.

But you lost 40lbs so why do you care about carbs/no carbs?

Nice to see a big win for the paleo diet,

http://www.lipidworld.com/content/13/1/160

All the markers of cardiovascular health are improved in the experimental group and they lost weight even though the researchers matched their calories to what should have kept them weight stable.

Can you image in that?  Jesus, everybody loses weight that should on a paleo type diet.  Too many vegetables and good fats... Hungry? Not.

It was mostly female, I'd agree, but that sex generally occupies the higher end of the obesity graphs. Better a tightly monitored small group of participants than a huge study relying on self reporting.  Small groups (of people or mice) seem to be adequate in nutritional studies.  I'd think that a small study of humans with a group of healthy fat/lean  body tissue would be interesting.

More conspiracy theories from that dodgy journal from Britain, the BMJ.  Industry bias in scientific research?  Who would have thought?

    Good read. Moa will probably hate it.

    • If 80% of your calories come from fat, you become better at converting fat to energy.
    • There is not a consensus that being more efficient at converting fat to muscle available energy actually improves endurance sport performance.
      • A high fat diet probably hurts performance when it comes to having to sprint during an endurance event.

      This quote is flat out wrong:

      Quote
      But, Dr. Burke said, no study to date has shown that extremely high-fat, ketogenic diets actually “enhance sports performance,” only that they make endurance athletes better able to use fat as a fuel. And the same studies generally show that high-fat diets blunt performance during high-intensity sprints, which, even in fat-adapted athletes, demand fast-burning sugar stores.

      Phinney showed this in studies on cyclists in the 1980s and it has been reinforced with numerous studies since.

          Nice article; not sure why I would hate it.  I've read enough Phinney and Volek to know basically everything in that article.  Nothing there to disagree with.  Shame the author didn't remind us of the improvement in cardiovascular and general health markers with a LCHF diet, although he did tell us about the nearly inevitable weight loss.[/list]

          "These results indicate that aerobic endurance exercise by well-trained cyclists was not compromised by four weeks of ketosis. This was accomplished by a dramatic physiologic adaptation that conserved limited carbohydrate stores (both glucose and muscle glycogen) and made fat the predominant muscle substrate at this submaximal power level."

          "The low RQ and the fact that blood glucose and muscle glycogen were maintained during exhausting exercise after 6 wk of a PSF suggest that prolonged ketosis results in an adaptation, after which lipid becomes the major metabolic fuel, and net carbohydrate utilization is markedly reduced during moderate but ultimately exhausting exercise."


          I guess you don't understand the difference between "not compromised" and "enhanced".

          My understanding (admittedly loose, interest in the endurance side of things is perfunctory) is that even though submaximal efforts are okay under keto, it's still not ideal because sprinting performance is impaired—the implication being that occasional sprinting is still part of endurance sports.
