40 pounds in five months possible?

Depends on how much you have to lose overall. The weight loss will slow down as you get closer to a healthy body weight.

Yes! I lost 40 lbs in 5 months. I am 5'4 and in May I weighed 204. By October I had lost 40 lbs (so over the course of 5 months) although now that I'm in the 160's my weightloss has slowed down quite a bit. Still going in the right direction though.

Good luck!

I also started out with running a 5k. I ran my first 5k on the 4th of July. Then in September- I ran a HALF MARATHON! I never thought I'd do something like that but I'm so proud of myself that I did. Running does amazing things for the body. Keep up with it!

unless you're overweight by 200lbs, no!. Plus, why would you want to lose 12lbs a month? That would mean you would have to eat no more than 1000 calories and workout for 6 hours a day

40 pounds in five months word work out to 2 pounds a week. At 240 that is certainly possible, but be careful!

You will be hungrier than if you did only a pound a week: you may end up binge eating.

Try it, but if you are too hungry: 1) eat more protein, fat, and vegetables; still too hungry: 2) spread out your meals; still hungry 3) try losing 1 pound a week instead.

at 240? Nah, no way in hell you can lose 40lbs in 5 months without losing a lot of muscle. That's close to 2.5lbs per week. Plus, weight loss isn't linear.

Your profile indicates that you're a 21 year old guy. If that's true, I'd say TOTALLY possible. Unless you have some extreme life circumstances, you probably have pretty good control over your time and energy right now, so you can devote it to your health. It might be a little different if you said you were working 70 hours a week to support your wife and 6 kids and you had no time to work out or think about your meals. But given that you are young and have a good bit of weight to lose, focus your energies, set your target.. on your mark, get set, GO!

I work out 45 minutes 5 days a week ( eliptical and belly dancing drills ), doing approx 1200-1600 calories. No troubles with hunger as im actually eating 2 large snacks and 3 meals but lean foods ( bean flour chips n hummus or salsa for the naughty snack cravings) . Ive lost 41 pounds in the last 5 months plus i GAINED substantial muscle mass. Highly possible. I started at 232 pounds

I lost 40 pounds in 3 months and 3 days.
It's possible.

I did it in 3 months also. No exercise.

It is totally possible, but it will take continuous motivation and a lot of discipline. I lost 40lbs. in about 6 months, but I'm also not super disciplined with my diet, and I also took a few 2-3 week breaks from the gym (due to sickness, exhaustion from working 2 physical jobs [swim lessons] during the summer, injury.) I'm certain if I were very precise in my tracking (weighing all my food), cutting out all junk food, fitting my macros to the T, and started strength trainer earlier in my journey, I'd be where I want to be. But, it's still a journey, and I'm making those changes slowly because I know for myself drastic changes do not stick.

Also, a tip with C25K, if you just started it, make sure you take the rest days in between. I made the mistake of doing it everyday when I started it at the beginning of the year, and after about 2 weeks I got really BAD shin splints that put me out of commission for about 2 weeks.

Might want to check your math. 40/5=8, not 12. 60/5=12. I could lose 2 pounds a week quite easily eating 2000 calories a day, as I need 3000 to maintain.
