Calorie in vs calories out

Hi folks, I have been using the Fitbit Charge HR which tells me I roughly burn 1750-1900 calories on days that do not exercise. To lose weight I'd have to eat less that 1750 cals per day... Does that sound right? It doesn't seem much. With this in mind, how many calories should I aim to eat daily to make sure I lose weight? Thanks

    To loose weight or loose fat? They are not the same thing.

    Assuming the estimate of 1750 is accurate, then yes, if you eat less than 1750 per day you should progressively lose weight. How far below 1750 is ideal would be partly based on how much you wish to lose, and how quickly. Also, for days you do exercise, you'll want to adjust accordingly.

    I'd love to know about the magic behind losing fat only. Surely he will enlighten us.

    OP - what are your age/height/weight? Do you plan on exercising?

    If you link your Fitbit to MFP and set your goals accordingly (with negative adjustments), it'll give you the number.

    My understanding is the Fitbit attempts to estimate something close to TDEE based on the user's stats, and the motion it senses through the course of the day. Not sure how reliable it is though.

    I burned almost 2600 calories yesterday just with work and no exercise...11,000+ steps.

    Hah! 1750 sounds like a LOT to me. I am at 1300 on non-workout days.

    maybe its what she burns with all day activity? since she said without exercise? I think she is talking what a person normally burns.

    I have a Charge HR too - and yes, if Fitbit is saying your burning ~1900 calories per day, then consuming less calories than that would cause weight loss, the amount below that would determine how much/how quick. It's basically establishing your TDEE for you. However, I have found using MFP to establish my Net Calorie goal each day is the best way of doing it, and then let Fitbit sync with MFP to give you adjustments to your MFP daily goal. It's not a one to one thing. MFP estimates what your body should burn each day, and based on your level activity the Fitbit sync will adjust that number up or down (assuming you have negative adjustments enabled). For me, I always burn way more than my MFP assumed TDEE, and therefore I get a positive adjustment from Fitbit.

    I believe the 1900 is her BMR+any activity.

    Well, if OP wants to lose 1 pound a week, then they would subtract 500 from that, and pretty much be where you are.

    Right - the Charge HR is constantly (almost) measuring your heart rate and then basing your calorie burn on that. So if all you do is sit on the couch all day, your HR should staying close to resting almost all the time. The more active you are, the higher your HR, the higher the calorie burn.

    Cut your calories drastically and do a lot of cardio. You will loose weight fast. but the loss will be both fat and muscle. Eat slightly under your TDEE and do resistance training and you will burn fat. The additional muscle will help with Leptin resistance and you will burn more fat. Fat loss is much better then weight loss.

    I have a similar burn for non-exercise days, but I don't focus on the numbers by day so I don't worry about what I burn this day or that day. Instead, I just set my eating goals that allows me to accumulate a 3500 cal deficit per week (to lose 1 lb./week). I don't always achieve it, LOL, but I'm finding that the Fitbit does a good job of predicting my losses (or lack thereof). :)

    Both of your examples will cause both fat and muscle loss. Your second option will reduce, but not totally prevent muscle loss. Generally speaking, for most people, over time, there will not be additional muscle acquired while eating in a caloric deficit.

    I'm new to this... What is TDEE?

    Total Daily Energy Expenditure. Essentially an estimate of the total number of calories your body uses on a daily basis.
