I just retired and got back from a month long trip where I gained 11lbs! I need to lose that plus some! I am very motivated since none of my clothes fit.
For late night snacking I have been successful with saving calories for a chocolate good life protein shake. I heat it up in the microwave so it comes out like a hot chocolate! It's a great treat with 30grams of protein to curb the hunger pains!
I also just made an egg sandwich for 26 grams of protein and under 300 calories. I baked egg whites, cottage cheese and everything bagel seasoning for the bread. Filled it with egg, tomatoes, red onion, avocado, capers and cheese so yummy! Will definitely make again.

Good luck all!!
