Welcome back!
I may not be the fastest loser on the planet, but I aim for moderate and consistency. Looking to lose 1-1.5 pounds a week (about a 500-750 calorie food deficit a day) is easily maintainable, not terribly restrictive, and can be achieved comfortably while still filling you up.
Isn't it better to shoot for a slower loss you can maintain for the rest of your life, than to shoot for a steeper loss curve, feel deprived, binge like mad and gain it all back?
I strongly advise you to start out at closer to 1800 calories and drop them from there to a point that is comfortable for you. Even if you only lose 1.5 pounds a week that is 75-ish pounds gone FOREVER, every year you stick to it.
Focus on your goals and commit to making changes you will stick with forever. My personal philosophy is that I won't even try something if I know it won't work for me through all the changes life can bring. So no four hour gym sessions, sauna visits, pills, liquid diets, or other junk. Moderate exercise I enjoy, healthy and filling food, and food journaling to count my calories.
That's what works for me, your mileage may vary

. The end result of a healthy, maintainable loss is the goal, however you choose to get there.
