Simplest... drink 4-6oz cold water each at the begginning of each hour.
If you need a stronger appetite suppressant you can order konjac root (main ingredient from most diet pills) from sites like puritan's pride..... it works but when I tried them I was never hungry and a person needs to eat or their body eats muscle. Work in more legumes into your diet and maybe consider researching 'slow carb' diet with weekends off for calorie cycling.
I also think short burst of exercise should be considered!
Bosu ball is low impact and excellent for abs.
Maybe check out Jane Fonda's new yoga video...it looked promising and she has an amazing figure!
So proud of you for choosing a healthier living!!!
