So, should your daily calories go down if your BMR goes down?? I started with a BMR around 1960ish and my calories were 1410. Now the BMR says 1869. Should my calories for the day also go down to reflect so i am in a 500 cal deficit??? Thought that was how it worked but maybe I am wrong?? Thanks!:smile:

    um you want to be a 500 cal deficit to your TDEE to lose 1lb a week not your BMR. you need to multiply your BMR by an activity factor

    BMR = Basal Metabolic Rate
    TDEE = Total Daily Energy Expenditure (also called Maintenance calories)
    Calorie = (unit of measurement), a unit of energy or heat variously defined. In nutrition terms, the word calorie is commonly used to refer to a unit of food energy. (The word calorie is used instead of the more precise scientific term kilocalorie.)

    BMR and TDEE are two different things..

    BMR is the amount of energy (calories) your body needs to function in a coma.

    TDEE is the amount of energy (calories) that your body actually uses (burns) each day by living your life.

    Eating less than your TDEE will give you a calorie deficit and you will lose weight.

    Eat less than your BMR and you risk slowing your metabolism down; making it that much harder to continue to lose weight and that much more likely that you will regain that weight when you get to maintenance.

    If you hit update diet/fitness profile in the settings tab, it will adjust your calorie goals to your new weight/BMR/TDEE etc.

    If eating 1200 calories a day is important, how come people who have lapbands and gastric bypass surgery eat much less and still lose weight? How come they don't go into starvation mode? I am so confused by all this.

    People who have surgeries like these are under a doctor's supervision and have strict diets to make sure all of their nutritional needs are met while on that diet.

    People who get gastric bypass or lapbands are usually extremely obese. People who are overweight or slightly obese but still exercise, should be eating more. Eventually, those people will need to more too. A huge deficit is only good at helping people lose weight for a short amount of time, depending on how much you have to lose in the first place.
