Calorie Deficit set @ 1.5# loss - Keto

just double checking here as my deficit seems high for 1.5# loss/week - Cronometer is telling me 750 kCal dificit and my BMR is 1450 - that leaves me 700 kcal....? I have been successful on 1200kcal with a 1-2 pound loss in the past. Maybe its just this system and I should set it at a 1# loss, even though I intend on a 1-2# loss? 700 cal/day is more extreme that I think beneficial.


  • Hi KetoDee,

    Cronometer calculates the calorie deficit required based on the amount of energy found in fat.

    1.5 lbs of fat contains about 5250 kcal.
    In order to lose 1.5 lbs of fat per week, would require: 5250 kcal / 7 days = 750 kcal deficit per day.

    Choosing a more moderate weight loss goal will increase your calorie goal for the day.
    1 lb per week will subtract about 500 kcal per day
    0.5 lbs per week will subtract about 250 kcal per day

    I wouldn't recommend eating lower than your BMR (the purple/pink section of the "Burned" Wheel). Doing so can make your body think it's starving and significantly lower your metabolic rate. (I have a blog coming out on this soon!).

  • I think I will adjust activity to sedentary instead of comatose - I chose that because of my tracker. Otherwise it says I am ‘over a lot, even tho I haven’t even eaten to BMR.
