Is Fructose the villain?

This is an amazing read, and is part of my cholesterol studies

“Consuming fructose-sweetened, not glucose-sweetened, beverages increases visceral adiposity and lipids and decreases insulin sensitivity in overweight/obese humans” found here

take home message is here:

“Studies in animals have documented that, compared with glucose, dietary fructose induces dyslipidemia and insulin resistance. To assess the relative effects of these dietary sugars during sustained consumption in humans, overweight and obese subjects consumed glucose- or fructose-sweetened beverages providing 25% of energy requirements for 10 weeks. Although both groups exhibited similar weight gain during the intervention, visceral adipose volume was significantly increased only in subjects consuming fructose. Fasting plasma triglyceride concentrations increased by approximately 10% during 10 weeks of glucose consumption but not after fructose consumption. In contrast, hepatic de novo lipogenesis (DNL) and the 23-hour postprandial triglyceride AUC were increased specifically during fructose consumption. Similarly, markers of altered lipid metabolism and lipoprotein remodeling, including fasting apoB, LDL, small dense LDL, oxidized LDL, and postprandial concentrations of remnant-like particle–triglyceride and –cholesterol significantly increased during fructose but not glucose consumption. In addition, fasting plasma glucose and insulin levels increased and insulin sensitivity decreased in subjects consuming fructose but not in those consuming glucose. These data suggest that dietary fructose specifically increases DNL, promotes dyslipidemia, decreases insulin sensitivity, and increases visceral adiposity in overweight/obese adults”

Cholesterol and coffee

If you know me well, you’ll know I’m running some  daily tests on my cholesterol status ( results due in 30 days).

Here was a surprise correlation that I thought I should highlight now.

So cholesterol is all about saturated fat! Right? So if you woke up and only had 3-4 cups of coffee  ( with 1 sugar and skimmed milk) over 5 hours,  missed breakfast and lunch, you’d expect your cholesterol to be low or high?

Enter Cafestol.

Check out Coffee Raises Cholesterol .

Cafestol, a compound found in coffee, elevates cholesterol by hijacking a receptor in an intestinal pathway critical to its regulation, according to a recent article. Allegedly the effect is negated if you pass the coffee through an old fashioned paper filter, but still, who knew!!

“In fact, cafestol is the most potent dietary cholesterol-elevating agent known, said Dr. David Moore, professor of molecular and cellular biology at BCM, and Dr. Marie-Louise Ricketts, a postdoctoral student and first author of the report. Cafetiere, or French press coffee, boiled Scandinavian brew and espresso contain the highest levels of the compound, which is removed by paper filters used in most other brewing processes. Removing caffeine does not remove cafestol.” 


Olympic lifts as a percentage of your back squat

It’s a big, big, sweep of the arm, but most of your lifts can be (could be) compared to your back squat. If you back squat 100kg, the chances are you can snatch up to 60kg, and clean 75kg. Bear in mind these figures could vary by as much as 15%

Front Squat Snatch Clean
 87.5%  60%  75%
Overhead Squat
Power Snatch Power Clean
Deadlift Snatch Pull Clean Pull
 125%  90% 100%

Waxman’s gym has a fascinating “Weightlifting Lift Calculator” here
Box Rox also has a nice assessment tool here
My take home message is this: once you start struggling with your olympic lifts, and your technique is quite good, start to consider improving your strength.

Chia seeds

Well, its all chia seeds now!

29 grams of chia seeds provides up to 42% of your daily recommended fiber,  plus phosphorus, magnesium, calcium and omega-3 fatty acids ( which are good btw!). Don’t take my dubious word for it. Look up :

“A dietary pattern including nopal, chia seed, soy protein, and oat reduces serum triglycerides and glucose intolerance in patients with metabolic syndrome” says so (check it out here).

What a read.

But, what this really means is that if you don’t include things like chia seeds and psyllium husks in your diet, you are a bit of a moron.

I should say,  however, that I’d never heard of “nopal” until I read the above  study. It’s a prickly pear cactus, comes from  Mexico and has a high   antioxidant, vitamin, mineral, and fiber content.

A sort of a sit up test

Coming from a functional fitness back ground, the  sit up procedure suggested by Goulding is a bit of a shocker!!

Lie on the floor  with your knees bent at approximately right angles, with feet flat on the ground. Your hands should be resting on your thighs. Just slide your hands along your thighs to touch the top of your knees, then back to the starting position (don’t tug or strain your neck)

Do it for 1 minute

Allow the table below to Judge you!

Fitness tests: the 12 minute run

The 12 Minute Run test

If you have 12 minutes spare, plus warm up and cool down time, you can find out: how aerobically fit you are, a theoretical VO2 Max figure and how well you do for your age. Run, walk, crawl as far as you can in 12 mins.  Then compare here.


If you want a VO2 Max “figure” try this (very crude) calculation:
VO2max = (22.351 x kilometers) – 11.288 =         mL/kg/min
Then look yourself up here:


Try not to kill yourself. You may need to build up running times, and possibly get medical clearance. Some need to walk. It doesn’t matter if your first go is a poor result. Use it to motivate you to get better.

The 2 “successful” diets

If we believe history  there were 2 great successful diets: The Paleo diet, and the World war 2 diet (true, we have never been so healthy). Both were dramatically different in  the types of food they used. Both relied on one thing for success, You couldn’t  get hold of anything to eat. Paleo is about running around the savanna trying to catch something with  a pointed stick before you died of starvation. World war 2 meant rationing.

If it helps there are 2 possible  approaches to healthy eating ;

  1. you get inspired about  a healthier future ( imagining better abs, less cancer,  healthier pregnancies, lower blood sugar)
  2. You get so  fed up with your present life style that you just have to change.

Both of these concepts feed into habit creation, and picking  the right battles.

Let me give you the common story among  successful weight managers. It happens to be  the same for  our  top Crossfit performers. There is nothing spectacular! There is no running around the streets, collapsing on your knee and praising God screaming out your new found goals

” I’ll never be fat again…….” “ill never eat  cake again”

Time and time again, religious revival campaigns have converted thousands,  only for them to relapse days ( sometimes minutes) later.  The more people tell you their extreme, detailed,  diet  plans , how much weight they intend to loose,  the more absolute rubbish the ideas and the more appalling the results.

Results come from  deciding on long term goals and plodding towards them. Result then come from building in habits, enjoying set backs, picking the right battles but keeping on the road. Ask any of our  olympic lifters, crossfitters and gymnasts.

Dramatic,  greedy , short term goals are deadly, stupid, destructive and of no value. You can as much  meaningfully change your weight in 2 weeks as you can become a lawyer in  a weekend (although I’m sure there is an online course somewhere that claims you can do that)
