My top tips include:
turn off you tv's- get moving, somehow, anyhow; the goal is to burn calories
don't buy sweets & junk food
if you do have to have a treat make the low cal version, homemade
limit how often you eat out- way too easy to get carried away
visualize yourself at your desired weight
use affirmations
don't hang out with people that want to sabotage you
try new things-yoga, dance, whatever floats your boat
when you reach your goal treat yourself to new clothes
don't get lazy- or you'll gain it right back
