3. Having pets such as a dog will help keep you fit by taking regular walks, you also get to meet alot of new people.
4. White bread is really bad for you and eat whole wheat
5. Mixing fruit and veggies with what you would normaly eat can make a significant difference
6. If you don't have variety eating healthy won't last
