Quick question - Which activity level for TDEE calculation?

I'd throw a guess out and just set it as lightly active. Remember, the activity levels are suppose to cover everyone, even sedentary people who don't do any activity at all, to the people who train every day. If you find that you're not making progress, re-adjust your calorie goal.

Another thing, it's good to underestimate if you're trying to cut and overestimate if you're trying to bulk.

Online calculators told me my maintenance was 2600 kcal per day. However, I tracked my calories every day for over a month and discovered my maintenance is actually 3400 kcal per day. This is radically different and explains why I rapidly lose weight and stall on my lifts when I try to limit myself to 2000 kcal per day. I strongly recommend ignoring online calculators and simply tracking your calories and weight every day in order to determine what your true maintenance is.

Hey bro, the Primal Six Pack IF Calorie Calculator is based on

• 3x Compound Movements / week
• 2x HIIT / week. The activity level is already factored in, simply select either Extreme Fat Loss OR Body Recomp and record the output.
