Is it possible to eat to much strawberries? I have been having them at breakfast then last few nights for dessert not sure how much I'm actually allowed to eat

Maintenance is a different ballgame. There's no set amount of anything. If you are still doing P3 breakfasts, just keep your portions of each food group within the guidelines. How you work out the rest of your day is totally up to you - how many calories you are eating for the day, how you are balancing your meals, etc.

I like routine eggs. Toast, Strawberries. Guess I can't maybe change it up. Have oatmeal instead of berries one day

Do what works for you! Maintenance is all about how you are going to handle eating for the long haul, and be successful at keeping the weight off. If that means having strawberries twice a day and your body maintains your goal weight doing that, no need to change it.

Ok. Thank you
