You need more veggies either salad or other allowable veggies like broccoli. Put some butter on cooked veggies to help up your fat intake. As far as the American Cheese, if this is the cheese you like don't worry it contains 1g net carbs per slice (most brands) & can safely be eaten on Induction, but if it's not important try using a less processed cheese like cheddar. I've used both with provolone & others too all along without problems, just be sure to limit it to 3-4oz daily. Like Kathy said restricting your carbs even lower than 20g will not aid in more rapid weight loss, so up those carbs with veggies. If you're not taking any supplements yet, then add a good multi-vitamin without iron too. Good luck & welcome.
