Is it possible to lose 20lbs in 2 months?

Quote  |  Reply

I am 4'11'' female 142 pounds and need to lose 20 pounds in the next 2 months, atleast 15. I'm 28, almost 29 and just really feel uncomfortable.  Do u think it is possible and or healthy?  I am planning to eat lots of fruits and mostly veggies, light meat and exercise but i am only planning to eat 1000 to 1200 calories per day. I mean that may sound low but I'm really short, I'm actually 4'10 1/2''  to be exact lol.  I dont know.  I am really depressed from my body, i feel stuck in it.  Do you think I can do it in two months, just in time for a special event?

possible, but not advisable. if you lose it that fast, it's almost guaranteed that you'll gain it all back and more, because you'll have slowed your metabolism, deprived yourself to the point of desperation, and learned absolutely nothing about healthy nutrition and exercise.

a good guideline is 1% per week, with an absolute minimum caloric intake of 1200/day.

^ ditto.

It's possible, but it's likely that as soon as you slip up you'll gain it all back and more in the same time or less that it took you to lose it. 

You honestly don't need to lose that amount in such a short amount of time. If you're going to do it, do it right so it's permanent.

To encourage you - I lost over 20 lbs in my first two months dieting, and I wasn't overdoing it.  I did start running twice a week at the same time (built up to 5k by the end of the first month).  So it can be done - following the guildelines here is for the best of course, but I wasn't about to increase my calorie intake to slow down my weight loss.  I've kept my weight stable after losing 30 lbs for a year now too.  For you I'd say create a 500 calorie deficit through physical activity - ensure you 1700 a day so you can maintain the deficit with 1200 intake.  I find this less difficult to pull off anyways - more food with more exercise, rather than doing nothing but sitting there feeling sorry for yourself with an empty stomach.  :)


I am in the same boat as you as well.. Hoping to lose the pounds with 1200 cals to 1500 cals... and 2 - 3 days a week exercise _ plus two toddlers ages 2 and 3.

Good luck... :)

Changing weight so quickly can make you feel really ill... I used to model and would have to be 7.5 stone one week, 8.5 the next, then 8 and so on... don't ask me how I did it but i did - and fainted a few times in the process. When i finally stopped modelling my metabolism was so screwed up - you may lose weight in the short term but in the long term you will be causing problems for yourself and may develop an unhealthy relationship with food.

Now I'm a little older and trying to lose weight the good old fashioned healthy way - slowly! Aim for 1-2lbs a week - in two months you could lose 8-16lbs, which is close to your target and really really great! AND in the process you will be teaching yourself lifelong lessons about nutrition and healthy (but still enjoyable) eating.

I know the desperation that sometimes comes when you want to lose weight, but please just be careful :) Try 1200 calories a day, but listen to your body and increase it if your body needs more. The tools on here are great and have really helped me :)

Good luck


Do you *need* to lose 20lbs in 2 months? Wouldn't you rather lose the 20lbs in 3 or 4 months, and keep them off for life, than lose 20lbs quickly, then have them come back? 1000-1200 calories a day isn't advisable, really, try 1300-1400. Your BMR (the amount of cals you'd burn doing nothing) is 1432, which is often recognised as the least calories you should eat in a day. If you have a lightly active lifestyle, you would burn 1939 calories a day, creating a 500 calorie daily deficit, losing around 1lb a week. 

For someone like you? Probably not going to happen.


Now - if you were 5'8, and 280 pounds, then yes, it'd be perfectly reasonable to lose 20 pounds in 2 months, but for someone with your body type it sounds a bit iffy. Maybe aim for like, 15 pounds in two months. =)

Please know that Calorie Count cannot and will not support you eating less than 1200 calories a day. We consider this unhealthy and CC is all about HEALTHY weight loss or weight maintenance.  If you plan to consume only 1000-1200 calories AND exercise, there is no way your body will get all the calories it needs to sustain itself.

From the "Ask Mary" section

Why eating only 1200 calories or undereating doesn't work

http://caloriecount.about.com/wont-lose-faste r-eat-calories-q3127

In the long run, you won’t lose weight faster by eating 1200 calories a day.  Under-eating deprives your body of essential nutrients and leads to muscle breakdown to provide energy.  With less muscle, you require fewer calories and you reach a weight low plateau more quickly.  Restrictive dieting also places you at risk for binge-eating which can lead to weigh gain and a life of yo-yo dieting. The Calorie Target calculator in the Tools section recommends ___ calories a day for you, personally, to lose 1.5 lbs per week, and so eat ____ calories, feel happy and healthy, and set yourself up for lasting weight loss success.

Here is a brief reason why never less than 1200 from the Advice section of Calorie Count Plus, under the Q&A tab:

Why must I eat at least 1,200 calories a day when I want to eat less?

In order to get the daily food servings you need for a balanced diet, it takes about 1200 calories a day. With careful planning, you could have a balanced diet on 1000 calories, but the restrictiveness of a very low calorie level can lead to binging and weight cycling, which will take you further from your weight loss goal. What's more, very low calorie diets can cause excessive muscle breakdown and metabolic adaptations, which can drive down your calorie requirements. In the end, you'll need fewer calories to maintain a higher weight

Your body needs at least 1200 calories per day to survive.

Here is a very rough scientific break down provided by a dietician for a 5' 2", 19 year old female weighing approximately 100 pounds, sitting around all day and doing nothing:

-The heart needs 12% of the calories (144 cals)
-The kidney needs 12% of the calories (144 cals)
-The Liver needs 23% of the calories (276 cals)
-The brain needs 23% of the calories (276 cals)
-The skeletal muscle needs 30% of the calories (360 cals)


At your height and current weight losing 10 lb in those two months will make a noticeable difference to how you feel and how you look.

I'm 5'4" was 170ish now just under 140 (74.5 kg - 60.5). I noticed a big difference after about 6 kg (10 lb)...and that's also when the compliments started to flood in. This gave me a huge boost to keep going well beyond my original goal! And that level of weight-loss is sustainable over a much longer time. Meaning that your overall goal of losing 20 lb is more achievable.

The risk with very low calorie intakes that you'll break the diet after a few weeks and end up having lost nothing by the special event is high because your body does scream at you to eat more if you routinely below 1200 calories. Mine does...the day after I eat that little (which I do sometimes more by accident than good judgement) I am ravenous...all day and even keeping a moderate deficit is tricky.

Eating a healthy balanced diet with lots of fruit & veg, lean protein, whole grains - but not starving yourself - does wonders for having good skin and bright eyes...which are also important to how you look for a particular event. Exercise will tone things up and give you energy and a healthy glow. If you look healthy and full of energy nobody will notice that you haven't lost quite as much as you hoped....nobody will notice - they'll notice what you have achieved.

I think the first step to successful weight loss is to set realistic, healthy targets.



If you ate 1500 calories and started lifting weights right now, you'd probably be down a size or two in a couple of months.  Why don't you try that instead?
