First I cut down the sugary stuff, then I cut right back on the starchy stuff, like pasta, rice and potatoes. I eat far more oily fish and oily nuts (such as almonds and walnuts), more grains (particularly the super-trendy quinoa) and have even taken to spiralising courgettes as a substitute for spaghetti. I cook with olive oil, eat full-fat yoghurt, snack on cheese and have switched back to butter. Eggs are a big part of my diet.
