A lot of my vegan friends love high carbohydrate diets. On the whole, they tend to respond really well to them. But all too often, they make the deductive leap that because it works for them, then it must work for everybody. Low-carbers and keto-philes are equally guilty of this n=1 conundrum.
Someone recently approached me at a fitness expo and asked me whether they should be doing an 80-10-10 diet (80% carbs, 10% protein, 10% fat). I asked her in reply, “Why do you think you should do an 80-10-10 diet?” She went on to explain that she had been advised to try it by a fitness competitor who is an advocate of vegan, high-carb diets and had been on it for a number of months. So I asked “How’s that working out for you?” “Not well,” she replied. We went on to talk about what had worked for her in the past, and she realised that despite 80-10-10 working well for her friend, it certainly wasn’t the best option for her.

In the modern world we eat more than ever before. But in spite of this surplus of calories, we may be functionally starving, because we may not be getting all that we need from the modern diet to truly thrive.
Starving for Nutrient DensityVitamins and minerals act as co-factors for literally thousands of chemical reactions throughout the body, from facilitating the breakdown of foods into energy, through to cellular reproduction, expression of genes and much more. Suffice it to say that without enough of the ‘little guys’ of nutrition, nothing much can occur in the body. I like to think of the micronutrients (vitamins and minerals) being like the spark plugs in a car. They don’t provide the fuel directly but allow its efficient use.
United States Department of Agriculture (USDA) data shows that some fresh produce (vegetables, fruits berries) only provide around half the amounts of some vitamins and minerals that they did in the 1950s.1 To get the same amounts of nutrients, we need to eat twice the amount of some veggies and other ‘nutrient dense’ foods than we did fifty or so years ago.

From the driver’s seat, to the office chair, to the couch when you get home, it seems we are spending more and more time sitting and less time walking around or standing. Researchers are suggesting that this increase in sedentary behaviour could in fact be wreaking havoc on our health. People have even come out and said ‘sitting is the new smoking’. This may sound a little melodramatic but it is true that this modern way of living or ‘not living’ could in fact be clashing with the way we are meant to be. This desk-bound work could increase your risk of type 2 diabetes and premature mortality (1).

Low-carb diets have received criticism due to their perceived effects on thyroid function, and the belief that this will have a negative effect on general health, along with performance and fat-loss. But the real picture may be less than clear-cut.
