50 lbs to lose in 4 months!

That's 12.5 lbs a month. Unless you're morbidly obese that's not going to happen. Why not just take it slow and steady? Try setting your goal to 2 lbs per week and see how that works out. Good luck with your goals and happy new year.

Did you do it healthily? Because even when I was counting calories and doing cardio 2-3 times a day I didn't even lose that much. Just asking.
