The Men Who Made Us Fat

 

It’s a refreshing change to watch a prime-time, mainstream programme that actually gets to the heart of the number one health issue that the nation faces.  The Men Who Made Us Fat stands in stark contrast to the constant diet of freak shows on Channel 4 (Supersize vs Superskinny, Secret Eaters etc…) as it attempted to explain, in a thorough, yet accessible manner, the history behind our current predicament and included some prize moments, such as a beverage manufacturer’s spokeswoman claiming black is white!

It’s a rather depressing tale of outright greed, political cowardice and how just a few individuals with axes to grind shaped the nutritional guidelines of the US and Britain and got it so wrong…

 

…it’s definitely worth an hour of your time!

Fish Oil – Essential?

I’ve not posted anything for a while, as I’ve bitten-off a number of complex areas to research and it’s taking longer than I thought!  I am also reading a very easy-going introduction to Epigenetics by Nessa Carey, by way of introducing myself to a topic that has really emerged in the years since I read Biology.  It’s a fascinating field and her book elucidates the common mechanisms that control DNA expression, for example, the methylation of the base cytosine to 5-methylcytosine (a process which switches the expression of the DNA off) , can be replicated and passed from one generation to the next.  Thus we are not just born of our parents, but of the environmental and nutritional milieu they inhabited and how that affected their DNA.

I was also going to post something about acid-base balance, but let’s face it, the kidney’s are complex things and I’m still in the midst of Renal Acid Loads!  That post might take a little while… Read more of this post

Nose-To-Tail Eating

In my post on ketogenic adaptation, I mentioned that the Inuit were sufficiently aware of the problems of eating excessive lean meat that they even have a name for the condition that effects those who consume only lean rabbits, when other foods are scarce.  Read more of this post

Heavy Squats and Pulled Pork: a guide to manipulating myostatin, testosterone, leptin and growth hormone. Part 2

This article in the European Journal of Nutrition indicates that undue fuss over exact pre and post workout feeding regimes and macro-nutrient ratios might be all for nothing.  A group of 10 ‘untrained’ college men participated in a study where they conducted three resistance training sessions: 3×10 reps (80% of 1 rep max – although how you work that out in an untrained athlete is interesting) for hack squat, leg press and leg extension.  2 hours prior, and 6 hours post exercise, muscle biopsies were taken and analysed for mRNA fold-changes in myostatin.  None of the feeding regimes appeared to affect the expression of myostatin.  However, biopsies post training showed significant  reduction in myostatin expression (p <0.05).

Does this have significance for those who already train regularly?  Would the same down regulation appear with training below 80% of 1 rep max?

Food for thought…

Standby for my next post, which will be on acid/base balance, and the role of dietary electrolytes and macronutrients in maintaining this balance (in particular, the role of acid load on bone demineralisation).

Heavy Squats and Pulled Pork: a guide to manipulating myostatin, testosterone, leptin and growth hormone.

Today I want to describe how a few simple tweaks to your diet and training program can reap serious rewards:  I’ll be looking at the concepts of intermittent fasting, overfeeding and resistance training, and the positive effects these have on your overall health.

Intermittent fasting (IF)

Too much!

There really isn’t any firm definition of what intermittent fasting is. It can be seen as merely extending your overnight fast until lunchtime, or even later, so that you end up having only a small ‘eating window’ late in the day.  This approach has been popularised in the strength training community by Ori Hofmekler’s Warrior DietRead more of this post

Keto-adapted military fitness Part 2

Today’s post is only a quick update, as I have found a recipe on Mark’s Daily Apple for pemmican.  I shall make up a batch and will then be ready for some serious keto-adapted military training!  It sounds as if the end result is a functional fuel rather than something you’d make to impress your friends at a dinner party, but I shall give it a go regardless!

Keto-adapted military fitness

Today’s post will be all about military ‘style’ physical training whilst consuming a ‘primal’ or ‘paleo’ diet (i.e. a diet generally low in carbohydrate and sugar, higher in saturated fats).  Whilst there is a strong affinity for the paleo diet amongst the crossfit community,  I have yet to read anyone’s experience of conducting longer duration military training on this type of diet.  It’s all very well training in a gymnasium and easing off a little/finishing your session early due to an issue with your energy levels, but when half-way through a long route march over Dartmoor it’s quite another matter!

So, last week, after a year eating a ‘primal’ type of diet (well, 80% of the time!) I went on my first 8 mile weighted march (55lbs plus rifle).   Read more of this post
