Is it possible to lose 40 pounds in a 3 month period?

Yes, start by chopping off your arms and legs.

At 144 already.. and looking to get to 104.. Probably not.

Haircut?

Possible, yes. Sensible, no.

Yes.

I lost about 60 pounds in 3 months once.

Gained back all of it, and here I am. Wouldn't recommend it to anyone.

What diet did you go through? I'm sorry about that.

I just ate 1200-1500 calories a day and exercised an hour a day.

The problem with quick loss is that your head doesn't have time to get in the right place. Up until the last pound, I was just focusing on the fact that I could go back to eating whatever I wanted when I reached my goal weight.

Depriving yourself is not a good idea - very dangerous for your body and mind.

to be honest its not realistic at all. it took me 4 months to lose 22 pounds. in all honesty to aim for that would set yourself up for disappointment. I would aim for something more realistic . I do mini goals and set them in 10 pound intervals.

I lost 40 pounds in 5 months. I am a very determined person and did not cheat except for maybe 4-5 days total throughout that time period. I was all over MFP learning everything I could to ensure success. Actually my goal was to lose only 27 pounds and I met it sooner than I thought!

I did 45 days straight of Jillian Michael's 30 Day Shred (10 days at level 1, 10 at 2, 10 at 3, repeat) and then Jillian's Body Revolution came in the mail. I did that for the next 90 days or so straight! There is one rest day per week built into that program, which I took advantage of.

I drank at least 8 glasses of water per day, cut down on cheese and bread pretty drastically. I stuck within what MFP recommends for me, and I usually ate back at least half of my exercise calories.

I started from a decent diet, just eating too much and really no exercise except for running after the girls- but I never broke a sweat doing that (well, a few times, but not regularly).

I bought a heart rate monitor to log my calories burned, pre planned my meals and measure or weigh ALL of my food to ensure accuracy in reporting. I believe in the math behind the numbers, so it is important to be accurate.

So I would say, 40 may be a bit too high. Set your goal at 25, that would still be a great weight! And you will be more likely to stick with your LIFE changes if you are making good progress on your timeline. BEST OF LUCK!

I lost 40 pounds starting at 240 lbs in 5 months - that was 16% of my body weight - in a very healthy maintainable way by using moderation.

You want to lose 40 pounds starting at 144 lbs in 3 months - that is 27% of your body weight. This would require extreme measures; nothing that would make you healthy in the long term. I would say the likelihood of you gaining it all back (and more) is 99.99%.

Unfortunately you can't do it and still be healthy. But that doesn't mean you can't tone up your body and look great. Plus, finding a great dress can help hide anything you couldn't lose in time.

At 144, I would think a goal of 15-20 is doable...

If you are a man yes, and healthily too (jealous) girls no and not healthily, not that fast at least lol

It is possible. I lost 30-40lbs in that amount of time a few years ago and kept most of it off, but I made a big life change to accomplish that.

I went from someone who never exercised at all to working out 5 days per week. I started the couch to 5k program and when I finished the program, I continued to run a 5k as my workout and just focused on getting faster. I also did some weight lifting. During this time I was not counting calories, but was instead focusing on eating more vegetables and less cheese and refined flours ( I have a serious cheese problem). I was definitely eating over 1500 calories per day...I don't think I ever eat too few calories.

I think it worked because I was really dedicated to the lifestyle change. I remember looking back one day and realizing that I hadn't missed a weekday at the gym in several months.

Getting liposuction at multiple places on your body. Going to the moon.

That's ~28% of your body weight.

Shoot for 3 months of learning a healthier lifestyle that results in a slow weight loss.

I didn't lose 40 in 3 months, but I did lose that much in 4 months. I weighed 179 on Dec. 24, 2011 & by May 1st I was down to 138. All I did was walk 4 miles a day and stayed under on my cals, having at least the minimum of 1200. I ate healthy, quality food including lean chicken, lean beef, fish, tons of vegetables, yogurt, nuts and seeds. I didn't feel hungry or deprived either. I'll also add that I was sedentary when I started out so that's probably why the weight came off so fast once I got up off my *kitten*.
Good luck, you can do this! Just do it in a healthy way and don't think about the '40 lbs', just do what you need to do, one day at a time, and it will come off.
