Question: Should you replace calories burned after exercise (specifically when you already take exercise levels into account while calculating your food goals)?
Example: I calculate my food/macro-nutrient goals by calculating my BMR using my LBM and use an activity level multiplier to come up with my TDEE which I consume 80% of in order to create a calorie deficit.
Since I am 5' 9", 150 lbs with about 16% body fat, my BMR comes out to be 1607 calories. I multiply that by 1.35 since I go to the gym five days a week to lift weights and consider that to be moderately active. That makes my TDEE equal 2169 calories. I multiply it by .8 to only take 80% of it and so, in total, I try to consume around 1735 calories.
Essentially, I want to know if I started doing cardio of some sort on any of those days (maybe high intensity interval training), would it be wise to increase my calorie intake at all if my goal is to lose weight?
Anecdote: My mom uses an app on her smartphone to track exercise and food intake. She wants to follow a consistent meal plan every week, but her app tells her after a cardio session the approximate amount of calories she's burned. She thinks she should replace all of those calories with whatever she can find, but I'm skeptical. How could one possibly plan for the exact number of calories the app is going to calculate?
