Welcome
You list the 2010 New Atkins plan as the one you are following, please re-read the Induction rules and other excellent advice in that edition.
1.
You should eat 15 NET carbs of the 20g as FOUNDATION VEGETABLES...approx six cups of salad and 2 cups cooked. A little spinach doesn't cut it...it appears most of your 20g net carbs were cheese, etc.
2. Limit Only 4 OZ of CHEESE...that is not "a lot". An OZ is a thin deli slice or 1" cube.
3. Dressings...only 2T per serving.
4. Protein only 4-6 OZ each meal.
I think these are excellent guidelines to help you eat more low energy density foods, control the protein and carbs and not be hungry. The stricter induction rules help you get into ketosis and experience the hunger lowering effect. It is a learning curve for guys use to eating larger quantities...appetite adjustment is built into the rules.
If the book you have seems complicated for you, many people here like the somewhat simplier instuctions of 3 cups veggies in the 1992 edition, pinned at the top of the Atkins forum.

But note, both plans have limits on cheese, cream, protein limits and to eat fat just to satiety. (Page 57, Savor, Don't Smother).
A few adjustments and you will be well on your way.
