For decades, we have largely described food by breaking it down into its constituent parts. Calories, protein, carbohydrate, fat, fibre, vitamins and minerals are measured, printed neatly on the back of the packet and used to tell us something about the nutritional value of what we are about to eat....

This is one that always gets my goat. Simple measurements like weight on the scale or even BMI (Banal, Meaningless, Irrelevant - that is my nickname for it) serve as little more than sticks to beat ourselves with. 

For decades we have been conditioned to regard body weight as one of the great arbit...

Ultra-processed food has become a massive conversation piece lately. If you ever want to get a group of healthcare professionals bickering like Tom and Jerry after 7 coffees, then just bring up this subject and watch the fireworks. It is a hotbed.

By profoundly reducing appetite and food intake, they can produce levels of weight loss that were previously difficult to achieve without surgery. But eating substantially less creates a nutritional challenge that d...
