Brilliant and entertaining nutritional blog...


I recently came across a fantastic blog about science and nutrition by a UK vet called Peter. He basically dissects nutritional research papers to determine if they are well-controlled or not. For example, most "high fat" diet research papers are flawed in one of the following ways:

1) Using trans fats (e.g. hydrogenated vegetable oils) as the source of fat.
2) Including 20% of calories from sugar (as glucose / sucrose / fructose)
3) Poor controls
4) Poor models (e.g. gene knockout mice that may or may not represent anything like human metabolism)
5) Biased assumptions leading to apparent "paradoxical" results rather than assessing the results with an open mind and considering that other models may be incorrect.

I highly recommend the blog, but it's perhaps a little heavy on the science jargon for those without a background in biology. Give it a go and see what you think:

Hyperlipid

I've gone through read every post and it's convinced me to at least give the ideas a try. I've reduced my carbohydrate intake again (I've already found the benefits of reduced carbohydrate, particularly sugar) and have increased my fat intake from butter, eggs, cream and cheese (I've always loved dairy and fortunately I'm not lactose intolerant). Interestingly, I've also reduced my vegetable intake (fruit intake has been almost zero apart from blueberries for some time anyway). So far, I'm up to around 50% of calories from fat and feeling great:

1) Increased libido.
2) Increased sensitivity to alcohol (this could be a good thing or a bad thing depending on your point of view, but I've found it beneficial for my single glass of red wine in the evenings).
3) Higher calorie intake for the same bodyweight. I'm actually trying to gain weight (i.e. muscle mass from increased weight-lifting) and finding it more difficult on a higher fat / lower carb diet).
4) Better compatibility with LeanGains (i.e. the intermittent fasting I've posted about before). I find it easier to consume the large amount of calories in a short space of time if they are from fats.
5) Less desire to eat carbohydrates.

I still eat carbs, but only on lifting days to replenish the glycogen and encourage an insulin spike for muscle growth.

(I hope Peter doesn't mind me using one of his blog pictures as my post picture - if so, please let me know and I'll change it for something else, but this seemed very appropriate!).
