Low Carb Diets

Today has been all about carbohydrates as a new study was published in the Lancet. I’ve spoken on ITV new  and Wave 105 radio about it and  video/audio clips are at the end.

So what’s the low down?  This is a controversial topic as low carb diets have become popular. I’m not against this, but I do think it needs to be properly thought through and planned out. Low carb diets are used by some dietitians clinically for diabetes control, weight loss and for some metabolic disorders. However there is a way to do it right. Let’s break the latest study down:

👉 This was an observational study and it used food frequency questionnaires, so not the best data as this is self reported after the event. It is easy to forget what you eat or under/over-estimate. However the study  was followed over 25 yrs  with over 15,000 people taking part.

👉 A U-shaped relationship was found with increased mortality on a high carb or low carb diet. Low carb being <30% calories coming from carbohydrates. High carb being >60% calories coming from carbohydrates.

👉Eating moderate carbs (50-55% of total calories) was shown to be best. This is what our UK guidlines are based on so we already advise this. 

👉 Swapping carbs for plant based fats and proteins has better outcomes compared to animal products. So if you reduce your carbs it does matter what you replace them with.

👉 This study didn’t look at the type of carbs eaten. We want to be eating #wholegrains and reducing refined carbs (unless you have a medical reason to eat a low fibre diet).

👉 Eating lower carb may help weight loss and with diabetic control but it’s all about balance. Not overdoing it and taking all carbs out. Choose sensible sized portions of wholegrain carbs with meals.

👉 Everyone is individual. If you are more active you may need more carbs. If you are recovering from an eating disorder you may need more carbs. If you on a special diet you may need less carbs. If any of that applies to you then seek advice from a #Dietitan or #registerednutritionist.

One big issue that comes out of all of this is we keep on focusing on individual nutrients. It is not helpful to break food down and count the grams you are eating or the calories from each nutrient and could be triggering for an eating disorder. Food is complex, it is made up of many nutrients some of which we can’t even give a precise measure of. So once again we come back to common sense nutrition, eating sensible portions of balanced meals and listening to your internal cues of hunger/fullness.
