The One Diet to Rule Them All…

Which diet is best for you?

I have recently been reading a lot of ‘diet books’ and related blogs and looking at some of the most popular diet programs currently in vogue.

Within the space of just a few days:

  • I read an excellent report on the benefits of ketogenic diets for type-2 diabetics and people suffering from neurodegenerative disease. The article was written by someone knowledgeable, intelligent, published and well-respected, and backed up by plenty of examples of people who have enjoyed success with ketogenic diets (personally, I know several who get great results!)
  • Then, without looking for it, the very next day I happened across a well-reasoned argument against ketogenic diets, again written by a knowledgeable trainer with a long track record of client success stories. He warned of the dangers of low carb diets negatively affecting thyroid function, and he shared many anecdotal stories of female clients who have suffered hormone disruption through trying ketogenic diets. He also argued convincingly that ketogenic diets can cause some people to suffer sleep abnormalities, hormone problems, mood swings, anxiety and misery (life without carbs – not much fun!)
  • Ummm, one blog full of reports of people going super low-carb and finally ditching that stubborn belly fat they wanted to get rid of. The other blog full of reports of people feeling tired, run-down, burnt out on ultra low-carb, who then ate more carbs and felt strong again and saw that stubborn belly fat finally melt away! Confusion much!
  • Then I was reading a book about the benefits of intermittent fasting and the health benefits of fasting in general. Again a well-researched and well written book, lots of scientific references and plenty of anecdotal references too. Mental benefits, fat burning benefits, metabolic benefits, weight loss, improvements in blood sugar management, insulin sensitivity and more
  • I had a look around online and found many blogs and groups proclaiming the benefits of intermittent fasting diets, full of weight-loss success stories…and I found a similar number of blogs and groups bemoaning that ‘intermittent fasting diets don’t work’ or that as soon as they returned to eating ‘normally’, these people regained any weight they had lost – “it’s just a fad” they proclaim
  • I read a wonderful book a couple of weeks ago about some of the newest research into the effectiveness of Paleo diets and how many people enjoy weight loss results on a Paleo-style dietary regime. Then I read a series of very confusing blogs, and it became clear to me just how muddled the Paleo message has become, which is kinda sad. Some people seem to interpret Paleo as meaning ‘fairly low carb’, and some seem to think it means LCHF (low carb, high fat) and some seem to eat lots of carbs. Some think ketogenic diets are an extension of Paleo, while others look at hunter-gatherer tribes eating high carb diets (many roots and tubers) and argue that Paleo is actually pretty high carb
  • Oh the glorious confusion! I found stories of folks getting weight loss results and improved health from all variants of this Paleo interpretation! These people were all following variations of what they believe to me a Paleo diet, some very low in carbs, some really quite high in carbs, and all achieving weight loss results or health improvements. Then I searched around and found opposing legions of people complaining Paleo is too hard, Paleo is too restrictive, Paleo doesn’t work and they failed to lose weight on a Paleo diet!

Myth busting – Part 4

Continued from Myth busting – Part 3

Myth: But longevity studies show that most 90 and 100 year old folks are vegetarians, right?

Truth: The truth is that in many longevity studies we see people in their 90s and 100s who ‘don’t eat much meat’ but that does not make them strict vegetarians.

In almost all the longevity studies I have read, very few of these people in their 90s and 100s were reported as specifically being vegetarians, most often they just “don’t eat much meat” because they tend to be quite poor (financially) and they can only afford to eat meat once or twice per week at most. Many of these elderly folks eat fish or eggs a few times per week. Fish is often readily available as many of the demographic groups studied (where exceptional longevity has been noted) live near the coast or on islands, so fresh fish is often a staple of the local diet.

This in itself is, to my mind, all far more interesting than whether or not these people are vegetarians. One of my all-time favourite books is ‘Blue Zones’ by Dan Buettner, an excellent review of the lifestyles of several societies where a high proportion of folks enjoy far-above-average longevity. In four of the five communities he and his team studied around the world, they live between the coast and the hills/mountains. A lifestyle including regular hill walking, daily clean fresh air, fresh fish and home-grown vegetables feature as key ingredients to living a long and healthy life. Many of the people studied “ate little meat” but only one of the five communities identified themselves as vegetarians, and this was in the case that vegetarianism came as a part of their religious belief system.
