3. Eat breakfast
It may seem like you are saving calories if you just chug a few cups of coffee, but in reality, you are delaying the firing-up of your metabolism. And, you are far more likely to overeat later.
Get a protein-rich breakfast with the family early in the day, and you will all likely enjoy the big feast more, and overeat less. Drink a glass of water before your breakfast in order to eat less and feel full faster.
