Is it possible to lose 18lbs in 1 month??

Weight loss is a result of a caloric deficit. To lose one pound you need to burn 3,500 calories

So, attempting to average that over a 30 day month:

18 lb x 3,500 calories per pound = create a 63,000 calorie deficit over 30 days

63,000 calories per month / 30 days = 2,100 calorie deficit per day (less food, more movement combined)

Can you do this? What does MFP say you should eat per day to maintain? You can also plug the same goals into MFP to see what it says.

No. You can't and you shouldn't. Do you want to cut off a limb???? And cutting out carbs and so called water weight is well, just nonsense.

Sorry, but it didn't take you a month to get to 210 pounds and it is going to take some time to lose that weight. Unrealistic expectations will only discourage you and keep the cycle going.

If you eat at a deficit and work out, you will lose weight. There a numerous threads on here to show you just how. Do a little homework. You will be glad you did.

I plugged in your numbers (and made up some others) in this Total Daily Energy Expediture (TDEE) calculator and got 2323 for your TDEE. It would be very difficult, IMO, to average a 2100 calorie deficit per day over a month, based on a TDEE so close to 2,100 already. If I had to guess I would say no, you probably couldn't healthily lose 18 pounds in the next month.

This isnt acurate if a person is just starting. Water weight is still there.....once that has been dealt with then you are correct. This person is obese. They prob have about 30lbs of water weight and can easily lose this in 30 days, Cut salt and carbs...DONE

I see what you mean, like if they want to fit into an outfit or something. Do you really think someone coming off of eating junk food could stay away from carbs and salt a whole month? I also took that into consideration (not very active) while assuming they might not be able to burn the calories to generate the deficit

You have to want it more than the alternatives. Ive trained lots of ppl that can do it. As a matter of fact I wont train ppl who havent hit rock bottom. Whats the alternative? Heart disease, stroke, cancer?

It may be possible, but it's not a very realistic goal. More than 2 pounds a month is generally considered unsafe. If you do lose the weight that quickly through crash dieting, you'll probably just gain it all back later because that isn't sustainable.

not likely without losing a limb

Many things are possible, I would never deny the possibility, only question the reasoning behind the strategy. That said, weight can sometimes come off easier and quicker at first the more you have to lose, you still have to diligently log what you eat and maintain a large deficit though. One month is a drop in the bucket though.... You'll have to keep it up a lot longer than a month to make a positive lasting change, so why only focus on a month?

Time Six months to a year WILL come around, then you'll have to ask yourself what you did with it. The better answer for the OP is I spent it losing weight healthily

Is it possible to lose 18lbs in a month? 18 lbs of what? Mass? Then maybe. Fat? No.

The scale is not the best way to gauge progress. It tells you what you weigh, but not how the components are distributed. For the same weight, muscle occupies less volume than fat, so it is possible to drop a couple of sizes and not see the scale budge just because of changes to your body composition.

If you want to obsess over a number, go ahead. People live and die by the scale (in some cases quite literally), and never realize the damage that they do to themselves in pursuit of a number rather than looking at their body composition.

You shouldn't try it, but you are in the obese range of overweight for your height, so if you are starting with a lot of muscle also, and you increase your amount of exercise to several hours/day, you can. If you want to see if you can survive being starved and not cause health problems or worse, that's another way. Either way, it will not be good for you, you will hurt your underlying musculature, and stressing your body to a more efficient burn (less calories per day plus less muscle = even less calories/day burnt) and even if you are successful, you will rebound and regain.

Im 210lbs and 5'4 (i dont workout last time i exercised was in april 2013)

and i eat junk most of the time

Now if i eat healthy and workout for 40min 3-4x per week can I lose that much??

http://www.myfitnesspal.com/topics/show/1115747-18-pounds-in-30-days The same question, from a 19 years old, in two different threads.......:grumble:

Depending on the circumstances, it can be. Although I think the questions should be why? What is it you really want to accomplish? What about next month? And how do you actually do it safely and effectively?

As someone else mentioned, I too lost an average of 15 pounds per month for the first three months. Since then it has slowed down (partly because of my activity level), but my clothes are still fitting better, etc. I only just yesterday wore a pair of jeans that was quite snug a couple of weeks ago.

I'm nowhere near done and I had a lot to lose in the first place, so the initial weight came off really quickly. It wasn't a sustainable rate of loss and I happened to be doing some very physical work (roofing) which isn't normal for me, but it was a nice jump start. My goal, however, is not that. It was to get to a healthy weight and become more fit. Otherwise, the first 15 wouldn't have really meant anything, because I would already have gained it back.

Also, I would like to mention that I never go hungry and didn't accomplish this much by ever starving myself. It wasn't a crash diet. It isn't "a diet" at all, although my diet has changed quite a bit, if you dig. Good luck with whatever it is you're trying to do - but I hope you keep it healthy.

Yes, but from the sound of your post, you won't; and if you did, for how long will it stay off?

No, if you intend on being healthy and keeping the weight off and look good by the end of this. Losing weight doenst just magically = sexy toned skinny like all those fake commercials and gimmics tell you.. You need to work out, move those muscles, lift, eat right and when you have to lose 80-100lbs to do that. Losing weight fast will only result in saggy skin, damaged bones, no muscle tone, hair falling out. The list goes on. If you intend to do this consult a professional to prevent this stuff from happening. But even they will most likey be against it long team.
