Do not ban foods

10. Do not stock junk food

To avoid temptation, do not stock junk food – such as chocolate, biscuits, crisps and sweet fizzy drinks – at home. Instead, opt for healthy snacks, such as fruit, unsalted rice cakes, oat cakes, unsalted or unsweetened popcorn, and fruit juice.

11. Cut down on alcohol

A standard glass of wine can contain as many calories as a piece of chocolate. Over time, drinking too much can easily contribute to weight gain.
