She likes slow-burning energy oats, which give her the energy she needs for royal events, working out, and raising children.

She eats well and works out regularly to keep her body the way she wants it.

Antioxidant-rich smoothies and watermelon salad are wonderful breakfast and lunch options.

Oats and oatmeal are good for your health in many ways, like helping you lose weight and lower your blood sugar.

People can lose weight and eat less by eating foods that make them feel full.

Kate might want to snack on raw fruits and vegetables, like goji berries.

Kate cooks with her kids, and their favourite things to eat for dinner are roast chicken and sticky toffee pudding.
