You should eat all your daily points every day. If you get what you feel are too many then eat full fat foods, like cheese to use the points vs. low or no fat which have fewer calories. I started out at 26 points and am now down to 19. Trust me at 19 you have no problem eating them all. Be sure to get in all the healthy guidelines.
You can bank your AP and use them throughout the week. You can only use up to the first 28 you earn each week.
You also get 35 weekly points which you can eat or not eat.
Keep in mind that the more you eat losing, the more you'll be able to eat once you hit goal.
Good luck! Join us on the WW thread.
