i did ww last summer with 1200 calorie/day and i dropped 30 lbs in one summer. i actually find the ww community beneficial when i really am slipping in to a dark space. i'm at my lowest mental place which is why i just joined this community. idk if any of that makes sense lol.
basically the concept of 0 point foods is that these are the kinds of foods you should be eating, like fresh fruits and veggies, lean meats, fat free dairy, etc. the goal is to encourage diets with those kinds of nutritional values. you have a set amount of points and like someone said it's about portion control. so you can still eat what you want, you just choose how much of what foods you want to eat. you could have an omelet with tomatoes, spinach, and fat free cheese for like two points and eat enough calories for a meal.
it's great for building a healthy relationship with food but i'm too scared to not be scared of food hahaha.
