Two more reasons…

… to ditch the carbs (as if you needed them):

Insulin, insulin, insulin.

undertakes a forensic examination of why poorly managed insulin and excessive carbohydrate intake damages the ability of brain cells to respire and may lead to Alzheimer’s and other lesser cognitive problems. Alzheimer’s is increasingly being referred to as “type 3 diabetes” and is becoming more prevalent as a disease.

Radio 4’s The Food Programme bravely explored the links between diet and Alzheimer’s here

Travis Christofferson considers the role of metabolism in the development of cancer. A surprisingly old idea that we seem to have forgotten about as we searched for cancer’s genetic secret… which doesn’t seem to exist. A book Cancer Research UK should read. Obesity doesn’t cause cancer… obesity and cancer are both consequence of poor insulin control and general metabolic damage caused by the over consumption of carbohydrates.

I’ll say it again, these are not new diseases and the answers are not new – Amy Berger cites TL Cleve from the 1950s – as I do. Travis refers to the Warbugh effect*, again described in the 1950s

… this survey echoes the need to urgently reduce the amount of sugary snacks and drinks…

We simply forgot the truth. Its time we remembered it. The healthy human condition relies on fat metabolism not carbohydrate metabolism. Thats why are genes are programmed to store many many many times more calories as saturated fat rather than glucose. Listen to the background music.

Given the choice of Alzheimer’s or cancer or something else, my advice would be die of something else.

*In oncology, the Warburg effect is the observation that most cancer cells predominantly produce energy by a high rate of glycolysis followed by lactic acid fermentation in the cytosol,rather than by a comparatively low rate of glycolysis followed by oxidation of pyruvate in mitochondria as in most normal cells. The latter process is aerobic (uses oxygen).

 

Weeknight fast (real) food 

I don’t get home until about 8pm on a Thursday as I run a high intensity interval class in the evening. I’ve run the class for quite a few years now and I have a lovely group of super enthusiastic regulars who seem to enjoy the buzz from the intense work out. I don’t believe that high intensity interval training (HIIT) by itself is sufficient – “fitness” is a combination of respiratory efficiency, strength and flexibility- but it is a useful component of cardiovascular training.

If you are doing it right, an HIIT work out should take you close to your maximum heart rate for brief intervals – no more than 30 seconds – followed by a recovery period at least as long as the work interval the objective being to get your heart rate back down before you send it back up in the next interval. There are loads of protocols available online using all sorts of equipment and none. Sprinting uphill and jogging back down is highly effective.

Anyway back to my point, I get in late and I want something quick and easy and no fuss. Rough and ready burgers and salad fit the bill perfectly.  I take 500g of organic beef mince and roughly form it by hand into 4 patties and throw it on a griddle for about 15 minutes, turning every couple of minutes.


While they are cooking I fish around in the refrigerator for whatever salad is available. This time of year it has mostly come from the garden. If there’s an avocado in there I will add that too as I think it goes great with burgers, it acts like lubricant as pure beef burgers can be a little dry.

By the time I have got the salad on the plate with a spoon of real mayonnaise, the burgers are ready and my perfectly primal dinner is ready. The little flowers are watercress. All it needs now is a sprinkle of celtic salt and you’re good to go.

Celtic Salt


Only 20 minutes start to sitting down to eat. Rough and ready Thursday night burgers. Perfect.

Asparagus season! 

Asparagus season is well and truly underway and the bed is very productive this year and almost producing more than I can use but I’m finding new ways to eat it. 


I used this morning’s crop to make omelettes for breakfast. 


I boiled the asparagus first and the simply folded the spears into an omelette and added some snipped chives too. Easy. 10 minutes maximum from start to finish and it looked great IMHO. 


Next time I will add some grated cheese into the middle of the omelette to make it a little richer as I was hungry again three hours later. 

I saved the trimmings from the asparagus spears and the water it was boiled in as it will make delicious soup with the bone broth from tonight’s chicken. You’d be surprised how much flavour the spears leave behind in the water. 

Wonderful asparagus! It’s the gift that keeps on giving.

You are not a bank account

Here we go… I have started another massive online open course (MOOC) and I think I might be addicted. This new one is from Johns Hopkins University and is taking a systems science approach to the global obesity epidemic. Rather than see it as a problem of an obese individual, it is looking at it as a problem of society as a whole. The shift in weight has happened right across society, even the thin people are fatter than they used to be! Are you listening Cancer Research UK? Spotted in a London tube station (well you could hardly miss it) 

Global Obesity – a Systems Science Approach

One of the things we often struggle with when trying to lose weight is that after a while it we simply stop losing it. Our body hangs on to the fat. We can’t understand it because we are eating fewer calories and exercising more so surely if the calories going into our body are fewer than the calories going out in energy burn, we will lose weight?  Just like a bank account, if we put in less than we spend the balance will go down (seriously, I know that to be true!). Prof. Tom Glass from Johns Hopkins sums up the Calories on/Calories out theory beautifully in this slide:

Slide1

Basically you can do four things with the calories you eat. You can burn them for fuel; use them to build stuff: waste them; or store them as fat. It doesn’t matter what kind of calorie they are, your body simply decides and decides the same way constantly, whatever. Obesity then inevitably occurs when the burning and the using of the calories does not equal or exceed the consumption. We store the excess as fat. But our bodies are not a bank account, the human body is a complex metabolic factory and its treasure is fat. The partitioning of calories is subject to hormonal signalling and fat is not an inert tissue! It is biologically active. Fat (adipose tissue) can increase insulin release into the blood stream which instructs the body to store energy (not just excess energy but ANY energy) fat.  The partitioning system also responds to the type of food we eat. Carbohydrate intake also raises our insulin levels that, guess what, instructs our bodies to store fat (eating fat, by the way, doesn’t). And just so we understand how elegant this system is, insulin starts to rise before the food is even in your mouth. Sit next to someone on the train eating sweet porridge and you start secreting more insulin and that’s not an good feeling. I know that from experience!

So a better illustration of what is going on is shown in this slide also from Prof. Tom Glass:

Slide1

Front and centre of the problem is the partitioning system, choosing to use or store calories based on the signalling it is getting from the food we eat and the metabolic state of our bodies. The more carbohydrate we eat, and unfortunately, the fatter we are, the more energy we will store as fat rather than use for fuel. This is the function of a single hormone and there are many hormonal interactions in reality. 

The ability of human beings to store fat (I have never seen a fat buzzard) is an evolutionary genetic triumph that has made us the successful species we are. Its a tragedy that modern food has turned it it an evolutionary disaster that is reversing medical gains and is now starting actually to shorten human life expectancy.

Did fat shaming just become acceptable? I was a little bit taken aback by the latest advertising campaign from Cancer Research UK which I discovered on my way to somewhere else. I didn’t really understand what the message is… apart from obesity causes cancer… it can’t be “if you are obese and you get cancer it’s your fault” can it? Really? 


But whatever the message is, CR UK seemed determined that we wouldn’t miss the posters…


And on both sides of the subway. No one seemed very interested though, apart from me.


Clearly if you thought you might be obese, you had the potential to be quite shocked at the thought you also had a high risk of cancer. But the message came without any suggestions about what you should do about it if you are at risk, no suggestions about where to go for help, not even any indication about what obesity is and whether the person looking at the advert should consider themselves obese.

All in all, and whilst I agree that people do not understand the risks of being obese, this is a pretty unhelpful approach in my view. People need help, not shaming, Cancer Research UK.

Love your garden and your butcher… the key to good eating! 

As my butcher is called Rob, it’s clearly love in a fraternal sense! Enough of that though… your local butcher is a resource to be cherished and cared for and of course used as much as you can.  By making friends with your local butcher you can start to ask him or her to source the best grass fed beef, free range pork or compassionately reared poultry and maybe get a good deal on the price too!! Here is my very competitively priced rib of beef from my local butcher on Ashtead Parade.


Now that is a beautiful piece of beef. Look at the marbelling of the fat that will keep it moist as it cooks. 

And then there is your garden (or allotment) if you are lucky enough to have one. Your own vegetables are a joy and totally organic, if you avoid using chemicals of course. 


Purple sprouting broccoli and asparagus from my garden. Perfect seasonal food. 

Meat cooked perfectly… 

Carve and plate with the vegetables 


Add some grated horseradish with cream and it’s paleo eating 101!

Love your butcher, love your garden, love your food. 

Friday = stretch

After my usual week of daily cardio/resistance workouts and leading multiple spinning classes, my Friday workout is always a 10 minute warm up followed by a full body stretch routine. Stretching is an exercise that is often overlooked or done as quickly as possible at the end of a workout without seemingly any focus or thought as to what the stretcher is trying to achieve.

If you read the literature you will see that there are different form of stretching – here’s a read out of the different types from Livestrong:

Static Stretching

Static stretching, the kind a fitness instructor leads at the end of a class, involves stretching a body part to its farthest position and then holding it for 30 seconds or more. It does not involve bouncing or rapid movements, just a mild, painless pulling sensation. You feel the stretch through the entire length and centre of the muscle and not in the joints.

Passive Stretching

Passive stretching is similar to static stretching, except that an apparatus or partner provides the force to stretch the muscle. For example, you may stand with your back against a wall while your exercise partner lifts your leg to stretch the hamstring. Passive stretching relieves muscle spasms and helps reduce muscle fatigue and soreness after a workout.

Dynamic Stretching

Dynamic stretching involves controlled swinging of the arms and legs that gently takes them to the limits of their range of motion. Here, parts of the body are moved with gradually increasing speed, reach or both.

Ballistic Stretching

Ballistic stretching forces a body part to go beyond its normal range of motion by making it bounce to a stretched position. It increases range of motion and triggers the muscle’s stretch reflex. Performing ballistic stretching can make you more susceptible to injury. Only highly conditioned and competent athletes preparing for strenuous activity should employ it.

Active Isolated Stretching

Active isolated stretching is most commonly used by professionals: athletes, trainers, massage therapists and others. To complete at active isolated stretch, you reach a certain position and hold it steady without any assistance other than the strength of your own muscles. Kick a leg up high, for example, and hold it up in that extended posture. Active isolated stretching works with natural physiological processes to increase muscle and fascia elasticity and improve circulation.

Isometric Stretching

In isometric stretching, as a muscle is stretched into position, you resist the stretch. For example, have a partner hold your leg up high while you attempt to force back your leg in the opposite direction. Isometric stretching is the safest and most effective method for increasing the joints’ range of motion, and it strengthens tendons and ligaments while retaining their flexibility.

Proprioceptive Neuromuscular Facilitation (PNF)

Proprioceptive neuromuscular facilitation combines isometric, static and passive stretching to foster a high level of flexibility. Perform it by passively stretching a muscle; isometrically contracting it against resistance in the stretched position; and passively stretching it through the resulting increased range of motion. It is an advanced form of flexibility training that also helps improve strength.

My recommendation is to use a range of different types of stretches to keep it interesting so that you are actively involved in the exercise and thinking about what you are doing – that way you’ll keep focussed. I start at the top of the body and work my way down slowly and carefully stretching all the major muscle groups to the point of reasonable discomfort without overdoing it. Each passive (see above) stretch is held for 15-30 seconds. After holding for 15 seconds I look to develop the stretch as my stretch receptors stop firing and I can get a bit more length in the muscle and connective tissue. I also use some dynamic stretches to seek to re-establish the flexibility and improve my range of motion in my joints after spending most of the 9-5 working week sitting at a desk. All stretch exercises should be careful, deliberate and thoughtful and taken to a point of discomfort not pain.

But why bother with it? It’s not really exercise is it? It’s just striking a pose. Well no, it is actually exercise and your muscles respond to being stretched in the same was as if they were being contracted through CV or resistance exercises. Your non-insulin dependent glucose uptake by the muscles fires up, GLUT4 transporters move from inside the muscle cell to its membrane and pull the glucose out of your blood into the cell where it is burnt for energy.

Stretching is exercise that will help you regulate your blood sugar, improve your focus, let you think about your body and wind down for the weekend too – s   t   r   e   t   c   h.
