Weight Watchers isn't set up for the eating style that you are incorporating, so you can't really compare if it's enough points. I don't mean to sound harsh, but if you want to follow WW, you should embrace the whole program or just count calories instead. WW is so much more than allotted points per day. I understand fear of hunger! I totally do, and I'm betting that a lot more will chime in here with the same fear. Here are some WW friendly tips that will help you overcome it.
Spread your meals out, know in your mind that you have 49 weekly points to fall back on if you get hungry at night. Also, you can exercise every day and have those emergency points for later if you need them.
Pre plan your day. Make a menu for today, or for tomorrow, where you have your meals planned all day, with a generous dinner and an evening snack. Make sure you use all of your daily points.
Find some low point snacks to have as a back up. 0-3 point snacks can't do too much damage to the weekly points if you need them.
Remind yourself that you have those weekly points and activity points, if you earn them. That is why they are there. They are your safety net.
Find something to do with your hands in the evening that will keep you busy and
satisfied. No boring stuff. A hobby, a household project, a craft, anything that helps pass the time that you truly enjoy.
Learn to build up your meals and snacks with power foods. They are usually high volume foods and will fill you up.
I promise, if you can do this for one day, you will gain so much confidence! Just one day, and then take it from there.
