    Wait - I'm kind of new to this and I"m a little confused. I went to http://www.fat2fittools.com/tools/bmr/ and calculated my BMR. I've been trying to eat between 1200 and 1400 calories/day (plus some exercise and usually not eating back those calories). The calculator said my BMR is 1313 and I should be eating 1603 calories/day if I'm sedentary. So I should be eating MORE?

    You can most likely eat more and still lose. Assuming you're accurately weighing and logging everything.

    At the very least you should eat back your exercise calories. I believe that calculator intends for you to eat a flat number so it should come out close to the same:

    1400 + exercise calories

    or

    1600 without exercise calories

    MFP does not include exercise when it calculates what you need. So, for example, people who are disabled or who do not want to work out can lose weight eating this much. When you DO work out, you need to eat more fuel for that. Otherwise you could be creating an unhealthy deficit.

    Based on your body fat percentage on this calculator, your BMR is only 1295.

    http://www.naturalphysiques.com/20/basal-metabolic-rate-bmr

    I used this site :http://www.fat2fittools.com/tools/bmr/

    Because I read on multiple posts that it was a recommended one. I like that it takes my body fat % into it, but I have an appointment with my doctor next week, so I will ask her as well.
    Your body will burn fat to sustain its calorie needs up to a point. The trick is just to have a calorie deficit that burns fat without pushing it so hard that you burn muscle as well or aren't getting enough nutrition. If you eat below your BMR your body will compensate by burning fat from your body or muscle depending on how far below your TDEE you are and how much exercise you are doing. Generally speaking it is safest and healthiest to eat somewhere between your BMR and your TDEE.

    The trick here is getting an accurate number for your BMR and an accurate number for your TDEE. There are many schools of thought and many calculators that will give you different values. The only way you can really find out is to use one of these calculators to estimate then rigorously track your calorie intake and expenditure over months and see where you end up. After you have that data you can sort of back calculate to see what your own personal BMR and TDEE seem to be on average and adjust accordingly.

    Yes that is a pain in the butt but I think that's the most honest approach if you really want to nail it.

    I really want to nail it.
    Ok I used your calculator and it gives two very different BMR numbers for you. One is the Harris-Benedict Formula and it specifies your BMR at 1898. The other formula it used is the Katch-McArdle and it read as follows: Based on the information you provided, body fat percentage of 58.1%, you have a lean body mass of 99 lbs., and your BMR is 1342 calories.

    I think the Katch-McArdle is more specific because it takes into account your lean body mass so if I were you I would not assume that your BMR is anywhere near 1890. I wouldn't start eating more. I would eat witht the assumption that your BMR is actually 1342.

    I need to get my body fat percentage calculated because I think this is a key number to have when trying out different calorie levels.

    Katch-McArdle disregards the energy required to maintain the bodyfat so it is not accurate for untrained obese people. You should use Katch-McArdle if you are strong and lean.

    WFT?

    But seriously, it sounds like you're well on your way. :flowerforyou:


    ETA: My advice re: BMR/TDEE/calorie limit is start with the higher one you have from that site. Figure out your calorie limit and stick to it...consistently...and weight and measure everything. Weigh daily (if you can handle scale volatility). Do this for 4-6. Monitor your results. With this information, you'll have the data you need to calculate your own specific TDEE. Adjust your limit accordingly (either up or down) and go again for 4-6 weeks. Repeat until goal.

    It really is this simple.

    Holy COW No, just no. There is no way her BMR is 1295. Its 1900. MINE is 1212 and I am 110 pounds.

    OP, keep on keeping on. You can do this. Just remember, everything is about your next good choice. It took me years to get where I am, and I did it by a series of good choices, a better one every day than I made the day before. I know if I tried it all at once, I failed every time.

    Good luck!

    Yeah you should definitely be eating more. If you starve yourself like that you are just going to end up losing your muscle, having your metabolism tank and your body suffer as a result. You might lose a lot at first but it will become harder and harder to lose and you will just feel worse and worse. If your BMR is 1300 and you exercise your TDEE (the amount you would eat to maintain your weight) is probably in the 1800-2000 range. For safe weightloss you want to eat calories between your BMR and your TDEE so probably something like 1500-1600 calories a day. You will still lose weight doing that and it will be more sustainable without causing yourself harm.

    Calculators like that are assuming that it is only your lean weight that is burning calories so it basically subtracts out your fat and only counts your lean weight. I think that is pretty wrong-headed personally. All that mass you carry around in fat certainly effects your BMR. Not as much as pure muscle of equivalent weight would but certainly not nothing. I mean you have to at least maintain bodytemperature in all that extra mass and that alone is going to burn a significant amount of calories.

    I think that your BMR should just be a guideline. Yes technology is awesome and is aiding us in getting to our goals, but I personally don't think..in aspect to weight loss..you should be afraid of eating too little. Yes so in the case of a person who has depleted him/herself with extreme deficits will enter starvation mode over time, but usually this will happen to someone who doesn't have many reserves . It doesn't happen in a day or in a week for someone who has a lot of excess weight. Worst thing that will happen is your metabolism will slow down, but it is physically very highly unlikely for a person to gain weight when the calories in vs calories out is a deficit.

    Starvation mode is caused by a huge drop in metabolic rate, over time. Eating too little will possibly cause your metabolism to slow down, and perhaps even to the point where it will prevent weight loss, but definitely not weight gain.

    Adaptive Thermogenesis is the process of metabolic rate slowing down over time due to a prolonged deficit, the more excessive a deficit is, the more weight lost. It actually slows down little by little. However when you jump back to the original lifestyle, the weight will come back. That is why it's best to make a lifestyle change.

    The bigger picture is that your body is losing weight every day, and you need to tweak your diet/intake accordingly.
    A woman's body is likely to retain water weight from +/- day 21 to day 7 in her cycle, for an average of 5 days in those days.

    People are scared to enter starvation mode, but it's unlikely, any deficit will cause weight loss,, which will require constant tweaking of calorie deficit (not starvation). An excessive/extreme deficit over time will cause extreme weight loss, and you will probably pick it up again if it is not sustained (which is referred to as starvation mode). Here is a little info, http://www.aworkoutroutine.com/starvation-mode/

    I don't recommend an extreme calorie deficit, it's extremely unhealthy and a fad diet which will slow your metabolism down in the long run and make all those precious pounds you lost come right back. Eating a tad over or under your daily requirements will not really impact your weight loss over time, many people keep weekly diaries as well, which is great, because if you over do it on Tuesday, you can fix it on Wednesday and not give up.

    My actual point is, listen to your body..learn to distinguish between thirst and hunger, comfort/emotional and real hunger, the psychology about weight loss plays a bigger role than people like to believe.

    “It’s very easy to confuse dehydration with hunger,” says Wansink. “We know our body is craving something and we just assume that it’s food – but frequently it’s liquids, especially in active people. I would guess that seven times out of 10, what people think of as hunger is really just a mild case of dehydration.” Extract from mind over fatter (which is an amazing eye opener book about how we think about weight)

    It has been a month now and I hope you have been successful!

    PS: I just wanted to give a clear description about starvation mode, I am not in any way intending that an extreme deficit diet must be followed, just that you shouldn't worry too much about starvation mode. Trust me, I've learnt the real hard way that shortcuts don't work in the long run. I have a fond interest in researching nutrition and how your body works via books, information sessions by doctors/therapists & internet, it's incredibly interesting :)

    Gaining 1 lb is nothing. My weight frequently goes up 1 lb one day, down 2 the next. In the days before my period it will go up as much as 5 lbs, then back down 5 once it's over.

    But weight loss is an evolving process, for your mind as much as your body. Keep asking questions, keep doing research, keep making adjustments. Just like you're doing. Keep it up!
