Why not? Not healthy as in pshhh 40 pounds you can do better than that, or to fast to soon?
When I was seriously working on my weight weigh, eating right, exercising, I went from 330 to 309 in less than a month. My Dr was over the moon proud and pleased and behind me 100 percent.

Losing 40 pounds in one month is not healthy in any way,
There are a number of reasons it can be bad for you to lose weight quickly. It can put a lot of stress on your body and disrupt your hormones. Often a very rapid weight loss will not only be fat - you will lose lean mass too. This is obviously bad because you need your muscles and organs in order to be fit and healthy - not to mention your body uses up calories just keeping your lean tissues alive, so the more you lose, the less calories your body uses each day and the harder it is to lose weight in the long run.
A very rapid weight loss usually means someone is following a very restricted diet, which can be bad because they may not be taking in enough nutrition to keep their body healthy. It's not just about calories, we need fat and protein and all sorts of vitamins and minerals to keep us running smoothly and a drastic diet makes it unlikely that you're getting everything you need.
Drastic diets are also more likely to result in the weight being quickly re-gained than a slow and steady loss. They also don't teach you many of the skills you will need to keep the weight off in the long run - if you were doing a liquid shake diet, for example, you're learning nothing about nutrition and portion control.
There are times when the risks of being overweight are greater than the risks of rapid weight loss - for example, when a person needs life-saving surgery and is at risk from the anaesthetic. In those cases they might be put on a very low calorie diet to lose weight in the short term - these plans don't worry about long-term sustainability because the most important thing is to get them through that operation. People on drastic diets should be supervised by a doctor to make sure they are getting everything their body needs to prevent them getting really ill from it.
It's generally said that about 2lbs loss per week is about the maximum to avoid losing too much muscle mass but there are some exceptions and people who are very overweight can often safely lose a bit more than that in the beginning, but any way you look at it, 10lbs per week is a huge loss.
To lose 1lb of fat you must burn 3500 more calories that you eat (roughly, there is some debate on the specifics but as a guide). To put that into context, 3000 calories is what an average sized woman might burn running a marathon. Now the larger you are, the more calories your body needs just to be alive, but only your lean mass uses up calories - not your stored fat. So a 250lb body builder will use a lot more calories than a 250lb guy who is carrying a lot of excess fat. There are very few women who will burn over 3500 calories each day without very hard exercise. So it makes me think that in order to lose 40lbs she had to eat next to nothing (since she can't do vigorous exercise). Which means she is likely not getting the nutrients her body needs. It's still unlikely she has lost more than 1lb of fat EVERY DAY for a month, so it's likely some of that is muscle loss and water weight.
Anyway - I obviously know nothing about the OP and it's possible she did do this under doctor's supervision and/or through medical urgency. I am not a doctor and this may have been the best thing for her to do for her health. But that's why people say rapid loss is unhealthy.
