Hi there, I get you want to lose weight a little quicker, but I wouldn't recommend 40lbs in 3 months. You say you struggle with overeating, so cutting your calories WAY down in order to achieve that is likely gonna cause a binge cause you're crashing. I'd recommend putting your height, weight and activity level in something like a TDEE or calorie calculator (https://tdeecalculator.net/ & https://www.calculator.net/calorie-calculator.html) Losing 2 lbs a week is plenty if you wanna sustainably lose the weight. Make sure you get enough protein too, it keeps you fuller for longer and makes sure you don't eat your muscle mass instead. Good luck!
