Anyway, if you do record your caloric intake, and your daily weight, you can get rather precise values. For example, take the 7-day average weight at the end of a month, and substract the 7 day average from the previous end of month, and divide the difference by the number of days in that month. Then multiply that number by 3500, and that's a very accurate description of your daily deficit or surplus. If you then substract this number from your average caloric intake (the whole calories eaten in the month divided by the number of days in the month), then remove the surplus or add the deficit, and this number is your average TDEE over the month. You can therefore calculate your homeostasis baseline. Although you don't want to be in homeostasis, so just keep your daily intake above the baseline.
