There are numerous claims on this forum for the benefits of this or that diet in reducing RLS symptoms. I am always happy to hear when any of us finds something that works for them.
However, I'd like to stress the importance of maintaining a balanced, healthy diet, such as the Mediterranean way of eating: a good balance of plenty of fruits and vegetables, whole grains, legumes, reasonable amounts of healthy fats (not saturated), and for non-vegetarians, perhaps some poultry and/or fish.
I certainly agree that reducing sugars and refined flour can be very beneficial. But eliminating all grains including whole grains, such as the ketogenic diets (which include Atkins and Paleo), result in a very unbalanced diet that should only be used for short-term weight loss, not as an ongoing way to eat. The British Dietetic Association named the ketogenic diet one of the "top 5 worst celeb diets to avoid in 2018". Link: bda.uk.com/news/view?id=195
From this article: "side effects may include low energy levels, brain fog, increased hunger, sleep problems, nausea, digestive discomfort, bad breath and poor exercise performance... It is never a good idea to ‘over-restrict’ any one food group (including carbohydrate), as this can mean it is more difficult to achieve a balanced diet overall with respect to vitamins, minerals and fibre in particular."
Fiber, it turns out, is very important in maintaining a healthy gut microbiome, which is in turn vital in maintaining good health, largely through reducing systemic inflammation. Inflammation is now being posited by some researchers as a possible cause of RLS.
In addition, there is no solid evidence that gluten is a problem for any of us, unless we have diagnosed celiac disease. However, refined wheat flour may very well be a culprit for us. I propose that we experiment on ourselves: if you believe yourself to be gluten-sensitive, try replacing your wheat-containing food ( e.g. bread) with a similar food made from a non-gluten-containing grain, such as bread from refined oat or millet flour. Then see if your RLS symptoms improve. If not, try eliminating all bread, and see what happens.
As for myself, I have greatly reduced my intake of refined sugars and flours of all kinds, including bread. I do eat a balanced Mediterranean-style diet, including whole grains and legumes. I have found this to be very helpful in reducing my RLS symptoms.
So all I'm asking is that we take a clear-eyed look at how we're eating and whether it's well-balanced. We might experiment to see what triggers our RLS, for instance alcohol, coffee, and refined sugars and flour. And to really investigate whether whole grains vs. no grains actually helps. And finally, please, let's be careful about promoting unbalanced ways of eating. Thanks for hearing me out.
