1. Junk food - There is nothing good about it. High in sugar and salt and filled with colourants and preservatives. The further you stay away from it, the better.

2. Sugary drinks - Cut fizzy drinks out for good and dilute fruit juice.

3. Butter - Do you really need butter all over your potato and on your bread? Bad for your heart and high in fat.

4. Coffee - High in caffeine and often drunk with lots of sugar, coffee can affect insulin production and gives you a power spike with a low energy slump a few hours later.

5. Alcohol - Sad but true. Although fun and social, alcohol is a stimulant and a depressive, extremely high in sugar and very fattening.
