Preparation is the key - ensure you have plenty of fresh fruit and vegetables, meat, carbohydrate and dairy products on hand so you can easily manage to eat healthily when you are busy.

In summer, prepare a huge salad using the unlimited vegetable items and keep in the fridge for snacking on whenever you desire. In winter make up a big container of soup using the same unlimited veggies and snack on as often as desired.

Eat food as close to its natural state as possible - try to consume raw unprocessed food items without added chemicals and preservatives. Keep a food diary to keep you on track and to help you to monitor everything that goes in your mouth.

Include fish or seafood in your diet at least a couple of times a week to top up on essential omega 3 fats that your whole body needs to be healthy. Avoid unhealthy trans fats found in foods such as margarines, hydrogenated vegetable oils, pastries, cakes and non-dairy creamers.

Food oils are sensitive to heat, light and oxygen. Keep your oil in a dark glass container away from any heat and avoid cooking with oil. Instead, use a non-stick pan and add a small amount of olive oil once the food has been cooked and the pan turned off.
