Did I exercise for at least 20 minutes?
Did I stay within my calorie budget for the day?
Did I keep track of everything I ate and drank?

    Jan 4 - goals met (4 days out of 4!)

    Tracked: Yes
    Calories: Yes
    Exercise: Yes - 30 min walk

    Thinking about calories: MFP sets my calorie goal at 1275. Out of the last 7 days, I've been under that 4 times, way over once (hello new year's eve champagne!) and under 1360 for 2 days. My tracked TDEE for the week was 2180 (taking out a huge day 1 - day 2 water weight loss), but my 7-day average for calories was 1378, even including the new year's overage.

    Moving forward with this challenge, I'm keeping my MFP calorie goal listed at 1275, but I'm counting myself as under calories if I'm under 1400. My spreadsheet is set up to track 2-week TDEE next week, and 3-week TDEE following that, and I'll adjust my personal calorie targets as needed based on the results.

    Who else here is tracking their own TDEE? (Hat tip to @craigo3154 for introducing me to this back in 2018 in the Biggest Loser challenge)

    Just a little expansion on this.

    TDEE is Total Daily Energy Expenditure. Calculating this is slightly different to the normal MFP CICO and requires tracking history and weight.

    TDEE takes you averaged calorie history and weight and works out what your base energy requirement is without exercise.

    It works on the assumption that 1 pound equates to 3500 calories. You need to take an average over at least a week as weight fluctuates per day based on water retention.

    As you are tracking calories and exercise and weight you can work out TDEE average without exercise through a simple formula.

    TDEE gives you a closer estimate to a true metabolic burn rate (without additional tracked exercise) than the usual MFP calculation as is is based off YOUR history, not average tables.

    The only way to get a TRUE burn rate is in a laboratory (CO2MAX) or using doubly labelled water. As both are not viable options for us in the real world, TDEE based of history of tracking, weight and exercise estimation is about the best we can do.

    I used this method when losing weight at my fastest to ensure that I did not have any long term adverse affects on my metabolism. (I dropped 50 lbs in 6 months actually had my metabolism increase to the point I was eating MORE calories per day in maintenance at 140 lbs than I was when I started at 190 lbs. This was dropping, on average, 5% of my bodyweight per month for 6 consecutive months).

    For this to work you MUST be obsessive about portion sizes, weighing and measuring food. The better the accuracy of the numbers going in, the better the accuracy of the TDEE measurement as the end result.
