My Day on a Plate: Zara Martin, model 2pm Vegetable juice (spinach, kale, celery, cucumber and ginger) and some nuts after the last shot. 3pm A meeting about a range of accessories I'm collaborating on, then I prep my playlist for an event I'm DJ-ing at tonight. 7pm Avoid the canapés but head out after the event for a big Greek feast: grilled halloumi, chickpea and artichoke salad, and lots of fish. 10pm A sneaky bit of Lindt salted dark chocolate. Chocolate is my sin - I can sink a whole slab in one go. Zara is an ambassador for Women for Women Zara's diet fads muddle what's otherwise a reasonably healthy day. Instead of drinking juices she could just eat more vegetables; instead of coconut water she could drink more water in general. As for giving up dairy - that will only help if she's allergic to cow's milk. Diet fads go up and down like hem-lines, but simple healthy eating is the timeless classic.
