    On n=1, Jimmy's 1800 and high percentage of Cal from exercise prompted me to review my stuff (based on my avail data sets I couldn't easily do longer). So for Jan 1, 2023 to Dec 31, 2024 my Fitbit "total energy expenditure estimation" ERROR went up! From less than 1% ten years ago to a WHOPPING 6%!!!**

    So basically ~177 Calories per day ERROR on an average intake of 2846 and expenditure of 3053 — adjusted figures should be ~2846 and ~2876 respectively taking into account the 5 to 7 lbs overall loss during this time period (from a trend in the 163/164 range to a trend in the 157/158lb range, with a peak near 170lbs and bottom near 155lbs!)😲

    The bike exercise is so much higher than that and yet I am barely reconciling myself to this EPIC "fail" 😝

    Off I go now, having to mentally reduce my posted deficits by ~200 Cal every single day! 😲😢😡

    I guess I will just have to console myself by no longer being obese😛 and by having made it through ten years of feeling better and being able to move😎! And I guess that 200Cal MAY be close enough for hand grenades!😝

    As to Jimmy… all I can think to suggest is the "take it easy" pathway. Make sure your thyroid stuff is all good. But maybe consider shifting some of your effort moving forward away from your traditional "lose weight for the cycling season" routine.

    Maybe try to deliberately fight for a more gentle and flat weight perturbation over a longer time period. Perhaps over 24 months peak to trough. Maybe even 36. As contrasted to accepting and adopting the lifestyle of going at it hard every year.

    One option for achieving that could be to continue your current efforts while aiming for a lower effective deficit… a thought process closer to "any" deficit is good and it doesn't matter how soon I reach "current goal"🤔

    ** this assumes, of course, that the quality of logging hasn't changed over the years, which would be incorrect. Plus the 27 un-logged vacation days over the two years were not exactly low intake ones!

    sorry Ann I sort of missed your EAT vs NEAT estimate. And percentages of tota.

    Sure, in situations where you have a specific "high end" exercise activity it may be "easy" to directly quantify EAT and separate it from NEAT.

    For many of us, and in particular when we use "all day" wearables that auto-recognize many of our favorite exercises, I think that it becomes a bit of a less meaningful distinction. And it is also dependent on the specific wearable's algorithms.

    For better or for worse (and this coming from someone who ten years in still measures food to the gram and spends half a day estimating % errors on their Fitbit), I find it a bit meaningless to be trying to be THAT specific.

    There will be errors. As long as they are not systematic some will cancel out in the wash. You then look at the expected vs actual trend over a long period of time. Consider what may be causing any unexpected issues such as why there may now be more or less divergence between expected and actual weight change as compared to previously… and you adjust. Rinse, lather, repeat.

    I agree with your general advice to @Jthanmyfitnesspal, if I'm understanding you correctly. Last time I decided to re-lose a few pounds in maintenance, I went ultra-slowly, and it was so painless I'd absolutely do it that way again. Coupled with an unwillingness - so far - to regain a big bunch (translation: not willing to buy bigger jeans), I'm happy with the overall strategy. I'm not @Jthanmyfitnesspal , so I don't know how he feels about those issues.

    I've also come to wonder if repeat substantial weight loss, especially sorta fast repeat weight loss, isn't cumulatively substantially more risky in adaptive thermogenesis terms than doing one round of major loss then sticking close-ish to goal. I gather significant yo-yos are bad for a variety of reasons, but I haven't cared enough to figure out whether there's been much research on the cumulative adaptive thermogenesis impact. For sure, it doesn't seem like there would be high-quality research, since the prospective study opportunities are likely to be rare, and self-report probably about the most viable methods for any reasonably large sample size.

    I do quibble a bit with your or your AI's seeming concerns about cycling calorie estimation.

    The 25% is the high end of the "more trained" GE, and appears to be the assumption implicit in the standard cycling calorie estimating formula, since (1 hour x 3.6 x 200 W = 720). Personally, given a choice between two or more reasonable estimates, I'll pick the low one . . . which this formula implicitly appears to do. BTW, it's the one I use for stationary cycling since I have a cycling ergometer with reasonable power metering. HR isn't going to be better, METS isn't going to be better . . . IMO.

    I still say "close enough", and think it needs to be assessed in context of probable estimation error for all the other components of TDEE. According to some reputable estimates, coefficent of variation for RMR is 5-8%. For me, that's a similar source of possible error in numeric terms. NEAT is even more of an approximation - probably the biggest source of variability. I'm not meticulous enough to spreadsheet it all out like you do, but I figure that using consistent estimating methods, choosing the most reasonable and practical ones available, is close enough, as long as body weight results are reasonably predictable from the estimates.

    Results are a better guide than calculators (including trackers) IMO, but results aren't tidily compartmentalized (or compartmentalizable in any practical way) between BMR/RMR, NEAT, EAT, TEF.

    This I agree with . . .

    . . . but inevitably, with one exception. And that one's probably personal.

    My good brand/model tracker (Garmin Vivoactive 3 followed by Vivoactive 4) is so insanely far from reality for me that I can't act as if an all-day wearable makes EAT vs. NEAT a less meaningful distinction. Garmin thinks my total calorie expenditure has averaged 1636 calories daily over the past full year. Libra says I'm up 2.7 pounds over that same year, theoretically averaging 26 calories eaten above maintenance daily. Would we assume something like 1662 average intake? No, I've eaten 2100-2200 most days, more like 1850 on rest days (usually once a week, occasionally more) and well over the 2100-2200 probably at least once or twice a month. The device is clearly seriously unreliable for me.

    BTW, I hadn't seen your message I quoted here before I wrote the one that appears in the thread after this quoted one. It probably sounds dumb in any case, but even dumber out of order.

    Apologies for the digression, @Jthanmyfitnesspal !

    @PAV8888 : You are right on the money! My efficiency factor is, of course, unknown, and might be rather good after all these years of cycling. In general, I try to not eat all the "exercise calories" back when I'm cutting.

    I've been fascinated by that "gross efficiency factor" for a long time. I only purchased a power meter for the indoor bike a few months ago. I'll have to check how much the calorie estimates have changed since then. For cycling, it goes way down when you ride out of the seat, which I do periodically. The evidence is higher HR at the same power.

    As you say, the agreed-upon efficiency factor is 20%, which means the average person utilizes 5x the energy that is applied to the pedals (an interesting number). I'm sure that's what they always use, come what may!

    @AnnPT77 : It's common for calorie-conscious people to do a lot of exercise. It can become a problem: People used to talk about "exercise bulimia," although I haven't heard much about it lately.

    I've gone for months burning on average 500kcals per day in exercise, mostly because I love exercising (swimming, riding, jogging, etc.)! It's getting harder, and I need more rest days. Also, I like to keep the workouts to an hour or less.

    PS I'm 1 lb below the NN0.0lb point today. But, I didn't drink a huge bottle of electrolytes as I usually do in the evening. So, it may come right back tonight!

    @PAV8888 : It's fun to read your posts, and your advice is, of course, totally correct: Don't gain that weight back! Beesus, I wish I could figure that out. But, this fall was really hard with a bad bout of sciatica. I was a mere 10lbs above my goal weight in September, by December I was 20lbs up. The first 10 came off very easily. The second 10 have been grueling.

    So, what have we learned? Don't ever get more than 10lbs above your goal weight! Even less is better.

    its so damned hard to keep your weight where you want it especially when youre having to be more sedentary due to injuries, etc. Lowering calories even further is something most people are unwilling to do.

  • AnnPT77
    AnnPT77 Posts: 36,586 Member

    Not to mention that - IMO - a person ideally would be eating maintenance calories or close to it, at minimum during the acute phase of healing. If in a deficit, a person has a bit of cushion where maybe they lose a little slower if calories are off, but potentially they still lose. Maintenance feels like a bit more of a balancing act.

    This is not remotely a criticism, nor do I presuppose any particular answer for reasons I'll explain, but:

    When you burn 500 average calories daily in exercise, do you feel that energy compensation (loosely, fatigue-related NEAT reduction) enters the overall picture?

    Certainly, there's good evidence that energy compensation may occur from high exercise levels, but how high is too high depends on a large number of complicated factors, including demographics, athletic history, health status, body composition, personal conditioning to the specific exercise type/duration/intensity, and more.

    If you're assuming your TDEE is around 1800, I see that 500 calories would be around 27% of that, and know that 500 calories of exercise for you is a different thing for you than for me - as you're larger, male, I think somewhat different age from me, etc.

    I'm also active for around 45 minutes to an hour most days, mostly doing things I find fun, but don't reach an estimated 500 calories in an hour even - for example - in a recent machine rowing hour that was nearly half zone 4 (145-162bpm, zone based on a tested HRmax, not age estimated). I estimated that hour more as like 400 calories. It was very doable, fun, and good for me in its dosage/context . . . but I was fatigued after, including into the next day. If I tried to do it often on repeat, there would be energy compensation. 😆 But that's me, not you, and all the variables are individual. (FWIW, 400-500 calories would be maybe 18-23% of my estimated TDEE.)

    I wasn't surprised by the <5% number in the cited paper, but because I assumed that that was based on population stats that averaged in quite a few people who exercise a half hour or so 2-3x a week (or less). 20-30% TDEE still seems high to me . . . partly because it would be high for me. That's a bias. 😉

    I do worry that some people here are not reasonably accounting for energy compensation, even though on other threads I've argued that other people are way too fearful of it. I also worry in some cases that people are going hard expecting fitness results that are unlikely because they're under-prioritizing recovery. And yeah, the ED expert people do seem to think exercise bulimia is still a thing, especially in a weight-management context, but I feel like people here are more likely to use terms for it like obsessive or compulsive exercise, or just over-exercise.

    IIRC, you're a long-term active person, so pretty fit. I think if people here on MFP are commonly shooting for 20%+ of TDEE in exercise, high odds they're overdoing, especially if relative beginners to being active. In that context, I think it's counter-productive to overdo, whether the goal is weight management or fitness improvement. I'm emphatically not saying it's overdoing for you. No idea.

    It's true that the National Weight Control Registry says their studied population of long-term maintainers do exercise: "90% exercise, on average, about 1 hour per day" and "the most frequently reported form of activity being walking". I'm guessing an hour of walking is <20% TDEE for most people, but that's talking generalities based on generalities.

    @AnnPT77 , @PAV8888 : Very fun and interesting discussion!

    Looking at my most recent spin, I had an average power of 163W, for a total work of 583kJ. The 20% efficiency rule would estimate that I expended 5 x 583kJ = 1915kJ = 697kCal.

    Garmin actually estimates substantially less that for the session, 588kCal ("active calories" only), which implies an efficiency factor of 23.7%. They may be taking other factors into account, such as HR. My spinning workouts include periods where I am not in the seat, and those are very inefficient (they get my HR way up).

    I have to say, looking back, it doesn't seem like the calorie estimates for my 1hr spin sessions have changed since getting the power meter. So, maybe Garmin things their HR-based formula is more accurate. 🤷

    Anyway: It's all an estimate and it pays to eat a bit less than suggested if you want to lose weight.

  • AnnPT77
    AnnPT77 Posts: 36,586 Member

    I see what you're saying about your estimates not changing with the power meter, @Jthanmyfitnesspal. Before you'd mentioned that, I'd actually wondered if Garmin does use HR, or uses it situationally, for cycling. I do connect my BikeErg to Garmin through Bluetooth, so Garmin knows some of the bike's data. Before I got this bike, I did just use Garmin.

    While I was thinking about the formula PAV's AI buddy mentioned, hours x 3.6 x average watts - my usual formula for estimating, too - I did a one-ride comparison. I picked an easy-math example, a 63-minute ride averaging 100W, and that formula yields 378 calories. Garmin's active calories for that ride? 378. Seems like an amazing coincidence. I admit, I got distracted and didn't math out other rides, so not sure . . . wouldn't be totally sure even if I had, Garmin being a bit of a black box. I should probably do the math, though, get some hints.

    yes. Simple. Not worth getting lost in the weeds over these things.

    Your body’s probably adapting to the calorie deficit, which slows things down. Mixing up your routine a bit could help get things moving again.

    Holy poops! This week features a 4lb weight loss!

    Not sure why, but a couple of things come to mind:

    1. I’ve been using NUUN to rehydrate almost every workout. It’s become such a habit that I’ve sometimes had one after work without a workout. I wasn’t thinking about it much, but it does have 300mg of sodium. This week, I ran out and was drinking water.
    2. I’ve been having a few treats after dinner, still with my plan. Usually, some dark chocolate and nuts. This past week I had things to do right after work, so I didn’t have time to snack. It was a very low-sugar and fairly low carb week.

    So, will I stick at this new weight, within a lb of my goal weight, or will I see a bounce? I’ll let you know. (I’m sure the suspense is killing you!)

    OK, I waited more than a week to post again on the "All About Me Blog." To anyone who reads this: I am in your debt.

    The 4lb weight loss of last week has been followed by bumping along my goal weight for a week, not yet crossing. Come what may, my cut ends next weekend. I may cross my goal and stay there, although I usually see a few-lb bump at the end of a cut.

    This has been a long road this time (21 lbs. in 6 months), which has made it very close to ~1lb/week, but it has not been at all linear. My age and hypothyroidism have made it very hard and I've endured a lot of hunger.

    I have to say, I like this weight and want to stick to it!

    Hats off to the intensity of effort!

    But now…… * F I G H T * :)

    As in. Don't stop being mindful…. for another 6 months at least.

    Because your "everything tastes good" cues and "just a little bit more" ARE going to come back.

    So a new goal could be.... delay delay delay! Flatten that weight curve by hook and by crook!

    Your loss trendline looks quite "in line"

    it's never easy from the ground level. But look at how pretty it is when you're zoomed out!

    @PAV8888 : Thank you for your awesome post! I’m gonna do it! I’m just below my goal weight today, so YAY!

    When you zoom out to 6 months, my loss looks pretty linear. But, I started this thread in March, when I didn’t lose hardly any weight. Plus there’s a huge weight spike, which was after Easter weekend.

    I am now 5 lbs heavier than I was after a similar cut two years ago. 🙊 I was over-relying on daily exercise at the time, so as soon as I had injuries, I gained it back! An important lesson.

    Best of luck to everyone else!

    Your average daily calorie deficit was about 401 calories per day for six straight months. Wow. And honestly, with how hard you train, I’d be hungry too.

    There’s a lot of math above (I couldn’t read it all apologies), but the takeaway is nothing short of IMPRESSIVE, no matter your age or starting point. Losing 0.5–1 lb per week is not slow, it’s solid, sustainable progress. Let’s normalize these results, and celebrate how exceptional this kind of consistency is, especially when you didn’t have a ton to lose to begin with.

    Personally, that level of deficit combined with intense workouts would be too much for me, I’d be constantly hungry (I’m younger and not hypothyroid). Maybe there’s a middle ground that makes maintenance over the next 6 months feel more manageable.

    Are you planning to stick with this lifestyle long term? Also, what results were you expecting for 6 months? 2-3 lbs a week? Just curious, what do you think would be different if you were younger and not hypothyroid? Are those results you would recommend to others who meet that criteria? Sometimes we expect more from ourselves than others, and we need to give ourselves some leeway and understanding.

    @ddsb1111 : I always use the rule of thumb that utilizing a pound of bodyfat requires under-eating by 3500kcals. At ~-1lb/week, that comes to ~-500kcals/day.

    Now, what's so agonizing is that my calculated daily deficit, based on a 1500kcal/day eating plan calculated by MFP (sedentary setting) and on calorie estimates provided by Garmin, was way higher than 500kcals/day (as stated above). I really had to ignore exercise calories entirely to lose weight this time. It means that my bod can shut down to closer to 1000kcals/day when it wants to (cold hands, etc.). Horrible!

    I’ve had cold hands my entire life, so I understand how annoying that is. In fact, I run cold everywhere, regardless what season, but I digress. Aside from that, you accomplished a lot so congrats! However, I would get your meds checked- things definitely don’t add up here.
