Focus on nutrition, not diets

Tiesler advises eating with a focus on fuelling your body, balancing your hormones and managing stress. The key is to address insulin resistance and reduce cortisol levels by consuming antiinflammatory foods. Think blueberries, pineapple, leafy green vegetables, fish, eggs, chicken breast, avocado and nuts. She also advises eating two tablespoons of fibre-rich flaxseed a day.
