I'm about 145lb 22 y/o, and also doing 1100 calories/day but usually in the form of one meal for dinner. How did you calculate the amount you should lose per da

  When I started I used a metabolic rate calculator. https://www.active.com/fitness/calculators/calories https://www.active.com/fitness/calculators/calories for example. The amount of calories lost per day = the metabolic rate from the calculator - the amount of calories you eat that day. The amount of pounds lost per day is: burned calories (above) / 3500 (number of calories in a pound of fat). After a couple months of measuring my weight daily and knowing exactly what my caloric intake was, I calculated my real average metabolic rate by doing the reverse. total calories lost in a period = lbs lost * 3500 calorie burn (metabolic rate) = total calories burned + total calories eaten The above is per period so I calculated the average values for the days in a month and used them. I didn't exercise much so the basal metabolic rate was fairly close to my real burn.

    If you aren't exercising much,the assumption that all loss is fat is optimistic, and lean body mass has only 600 kcal/pound instead of 3,500 for fat.

      Yes that is also true. I accounted for about 20% of lean mass loss included and then had to hit the gym after the few month diet :) Though it wasn't my biggest concern since I overshot my loss by about as much.
