Hi msmarmar23. Congrats on starting.That's always the most difficult part!!
I don't know if I have an older version of the CALP diet (book is copyrite 1997, published 98) than watigress but mine definatley says have a snack ii you are hungry. Snacks must be from craving reducing food list and include both protien and high fiber veggies.
From my own experience this is not a fast diet but one that is easy to stick to because it allows so much flexability. Low fat protiens-eg tuna, real meats (unprocessed meats) will be better choices the the high fat processed foods, but I'm not sure if this is a fat or a salt thing. A good rule of thumb is 10x body weight in calories. So at 175 a person could have 1750 calorie intake and still loose wt.
The balance of food is the most important. If I want dessert I will have no high carb veggies. I useally try to eat the complex carbs -Vegetables of fruit rather than a sweet dessert High in carbs but not fiber.
I loose about %lbs a month on average after 6 months.
Hope this info is helpful, and this is only my take and what works for me!!!
Have a good one.
