O.k it isn't often we have a bit of a rant on here, but today we are going to....
We recently saw a comment by one of the U.K's "leading" nutritionists on a website, which stated unequivocally that the "only reason you lose weight on a low-carb diet is due to water loss not fat loss".....
O.k, take a deep breath and count to ten, and you've probably got someone writing this who would tell you that low-carb = Atkins, that high (whatever they consider that to be) protein intakes cause kidney failure, that ketosis is terribly bad, that you NEED to eat carbs for energy, and more similar rubbish.
Firstly, we should add that you do often lose water on a lowered carbohydrate (and we are talking sugars and refined carbs here) intake, but I'm not sure why that is such a big deal! Carbohydrates that are refined raise insulin, which in turn leads to the kidneys retaining salt and the body holding on to fluid. This is a major contributor to high blood pressure....(despite all the press that tells you to limit salt, you'd be better off cutting out bread, flour, fruit juice, and other such insulin promoting foods). So, the more accurate statement would be that high-carb diets promote fluid retention!
I am always surprised at how many folks I meet who will soon chastise you when you mention the notion of improving health through controlling carbohydrates, or who think that the Atkins diet is the closest thing to nutritional heresy you can get. Despite this next to none of those I meet look particularly athletic or in particularly good shape, not only that but they have rarely, if ever, read the literature, or even tried it out themselves (if they had they would know how important the role of vegetables is in these approaches). Very few have read the considerable evidence for the role of sugar and refined carbohydrates in heart disease, cancer, diabetes, and many other 'western' diseases. They will often baulk at the thought of eating any saturated fat - despite the fact that many native populations around the world live on exceptionally high intakes of fat and only started displaying heart disease and cancers when their diets were corrupted by refined sugar and flour-based products. In fact their nutritional viewpoint is all too often based on uncontested dogma, that is often outdated and in many cases equivocal as to its reliability and relevance.
It is amazing that even in the presence of such overwhelming evidence for the role of refined sugars and flour products in our diet being directly responsible for many diseases and health conditions - including obesity - that we still make saturated fat the dietary pariah and hence the extensive amount of "low-fat" foods out there.
The yoghurt ad on tv right now is another example, with women shredding 'fad-diet' books in favour of a LOW-FAT yoghurt. Unreal. Perhaps they haven't heard of the Ornish Diet or Piritkin diets??? Both in my mind true 'fad-diets' at worst, but even at best no better than 'Atkins' or 'Protein Power' (by the brilliant Michael Eades....)
Eating low-fat is a fad and for most signals a diet full of processed crap full of chemicals, sugars, and additives all put in to replace the taste and satiety that came with fat.
Thankfully more and more of us are waking up to the reality and understanding that eating highly processed foods, refined sugars, and refined carbohydrate products are the real danger to our health. That doesn't mean we all exist on bacon and eggs either, most 'low-carb' eaters I know are the ones loading up their plates with broccoli, spinach, and other veggies next to their meat!
If you are interested in finding out more I suggest you get hold of a copy of 'Diet Delusion' by Gary Taubes - but prepare to have some of what you believe to be challenged!
