Is loosing 20 pounds in 3 months unhealthy ?

Also, it depends on how you get there....

I've lost 22 pounds in just over 10 weeks. I've done this with healthy eating and lots of exercise. I've had slip up days where I ate too much, weeks were I haven't exercised much at all. On only a handful of days I've gone under my calorie allowance, but mostly I've been over the minimum set for me . I dont eat back exercise calories but I dont stress about going over my daily allowance either.

I do have more weight to lose than you do. So I think losing 20 pounds in 3 months was not unhealthy for ME. Would it be healthy for everyone, no in my opinion. For some people it would be a unreasonable amount of weight to lose.

It depends on how fat you are and your specific needs. Only your doctor can really tell you what is healthy for you.

I lost over 20 pounds in two months when I began losing weight, but I began at 250. Now, in the 150s, there is no way I could lose 20 pounds that fast. I wish. But if I stick with it and am patient, I will drop 20 more pounds...and so will you, if you are patient and stick with it.

if you have a lot to lose like i do, i lost it very quickly in the first 2 months. The less you have to lose the slower it goes. I wish it was fast but as others have said, i didn't put this weight on overnight. I'm learning to eat healthy portions & food, i'm learning to deal with ups and downs.

A close friend who's a doctor said that, in a weight reduction phase, one shouldn't lose more than 10 pounds per month. (Of course, with a lot to lose, it might be more than that in the initial months.) More than that is not healthy and also is more subject to regaining down the road. So I'd say 20 pounds in 3 months is a healthy goal. Achievable, as the others were addressing above, might be another matter.

I have lost 22lbs in 3 1/2 months but I still have another 22lbs to lose and expect it will take longer to lose the second half of my weight. I have got healthier - blood pressure normal, cholesterol normal

That is completely dependent on the person. The goal or how far away from it you are doesn't really matter. Studies show that to maintain muscle mass and lose weight healthily you want to keep weight loss between 0.5-1% of your body weight per week, while exercising and eating sufficient protein. For me, that means even though I have ~7lb to goal (which I intend to overshoot so I bounce back up to goal), I can continue at 0.9-1.8lb/week because I still weigh 180lb. I also monitor my LBM with a circumference method and calipers and it has fluctuated up and down in a 3lb range (right now it is on the up side).

If you weigh 220lb to start, it would be possible to lose ~2lb/week (average, 2.1lb, then 2lb, then 1.9lb) for 12 weeks, or ~24lb in 3 months.

If you weigh 150lb to start, it wouldn't be healthy to lose 2lb/week. Instead you'd have to average ~1.4lb/week over 3 months or ~17lb total.

However, both of those goals are hard. I started at 220lb and lost 2lb/week and by the time I was 195lb it was really starting to get lousy, so I switched to a 1.5lb/week goal. I say go as fast as you healthily can, but you have to know yourself and what you are capable of. If you hit the point you want to quit you have to just reduce the pace but keep going, otherwise you would have been better off staying at a slower pace that you can maintain longer.

If you've only got 25 lbs to go to get to a healthy weight (according to your profile), then yes, that rate of loss will be unhealthy, as you would have to eat close to or under your Basal Metabolic Rate, and not fuel any of your activity, which would lead to fatigue and worse health problems.

You didn't gain the weight that quickly.

Learn to eat sustainably - a habit for life.

Agreeing that when you only have 25 pounds to lose, losing 20 of them in three months is not healthy or realistic.

@barbie934 - set your weight loss goal to 0.5 pounds per week. http://www.myfitnesspal.com/account/change_goals_guided

Perfectly fine

since you only have 25 pounds to lose I would say it is probably not realistic. I started with a goal of 50lbs lost back in may (started at 170, goal 120 and i'm 5'6). So far I have lost 20ish and it took me move then 6 months of eating 1200 cal. to do it, and i work out. A more reasonable goal might be to lose 12 lbs in 3 months and maybe shoot for 20 in 6 months.
I know everyone is different but I think most people do better with goals they can achieve
