calories for sedentary work + activity

hi, I have a question about the number of calories for the sendentary level. I am a 47 yo male, and I have a sedentary job, but I do a lot of cycling and some occasional other physical activity. However, I chose to file myself as sedentary in the app and log all my workouts separately, as my training volume varies from week to week. This worked well when I wanted to lose weight, but now that I want to remain stable, I have the impression the amount of calories for days when I do no exercise is too low. It is 1770 kcal currently. I checked this website https://www.hackensackmeridianhealth.org/en/healthu/2022/03/11/how-many-calories-should-you-eat and it gives 2200 kcal for a sedentary male of my age group.

Also, I am not sure it is good to eat more during days in which you workout and less during rest days, so my approach is probably not ideal if I want to improve fitness. But the activity levels proposed in the profile do not appear adapted to cycling training. When I do a long day on the bicycle for example, I can consume 4000kcal in addition to my sedentary baseline, while on other days I may be only 400kcal over.

    Hi David, what does MFP give you when you set your goals to maintain and select either sedentary or lightly active? I would start with lightly active, monitor for a few weeks, then increase or reduce calories slightly as needed. Continue to log and eat back your exercise calories.

    You're going to just have to pick one and use it, then adjust as you go. If your exercise varies a lot, this site's more nuanced calculation tools may be better - or you may choose to use a flat number of calories every day regardless of your exercise.

    Both ways are valid, depends on your preferences. I personally prefer adding exercise separately, but I already ran the "experiment" over a period of time to establish my personal use patterns. You'll have to do the same.

    Here is the method used on myfitnesspal and the backing verification numbers:

    Unlike other sites which use TDEE calculators, MFP uses the NEAT method (Non-Exercise Activity Thermogenesis), and as such this system is designed for exercise calories to be eaten back. However, many consider the burns given by MFP to be inflated for them and only eat a percentage, such as 50%, back. Others are able to lose weight while eating 100% of their exercise calories.

    Calculators are all estimates. Try this one below. Your BMR estimated by various calculators may be roughly correct, but will be too low if you have a lot of muscle mass. How they get to their own definitions of "sedentary", "active", "very active", etc. is multiplying their BMR estimate (which may be wrong) by some arbitrary number like 1.2, 1.4, 1.6. So there's enormous room for error. Same goes for how many additional calories you think you burned doing exercise. Was it high intensity, was it moderate, how do you really know? That's often a guess too.

    When I use this calculator e.g., my TDEE (as found by tracking my input calories and weight since the start of the year) is about 300 above the Miffin estimate, and 150 above the Harris one. I attribute that difference to a) I think I have more muscle than the average guy my age, which burns more calories, b) I'm probably taking in more protein than average, which has a higher thermic effect.

    Track your data yourself, calculators are starting points, not definitive.

    it makes sense to eat more on days you use more energy.

    every calculator gives me different amounts to eat for my goals, so take any number you get with a grain of salt. the calculator you linked to doesn't even include height as a factor, and men who are 6'7" are going to need to eat more calories than men who are 5'8". if you aren't losing weight eating the MFP recommended calories, that works, and if you do continue to lose weight, you can set your calories higher or change your activity setting to a higher level.

    what works for me is that i set my activity level to sedentary and add exercise on bike, treadmill, etc.

    I think it just depends on what works for you and is doable. When I changed to maintenance (and even for the very end of me losing weight actively) I had started exactly as you...used Sedentary as my activity as I have a desk job and other than my intentional activities I am on the couch or in a chair. So some days I'd eat as little as 1300-1500....and then some days I'd have to eat like... 2200. That was not really comfortable for me to eat that much especially of homecooked stuff (I'd be able to do that fairly easily if I did fast food a lot). So then I switched to using my actual TDEE, as my activity through the week was consistent. It was easier to simply eat ~1800 calories every day than go up/down with my activity daily.

    Your best ccalorie needs estimates come from you own experience data. If you've logged your eating carefully, and weighed in fairly often, you can estimate that yourself.

    There's a whole thread over in the Maintaining Weight part of the Community, in the Most Helpful Posts there, where people talk about how to determine maintenance calories. It has details about the "use your own data" method, so I won't repeat that here. Here's a direct link to the thread:

    https://community.myfitnesspal.com/en/discussion/10638211/how-to-find-your-maintenance-calorie-level/p1

    Your variable exercise does have an impact on what may be best for you, but so does personal preference.

    My schedule is similarly variable most of the year (on-water rowing, cycling). I chose to do the base calories + exercise approach (and have done for over 8 years now, loss then 7+ years maintaining). I admit I don't run a structured training plan anymore that gives me specific athletic goals, but I haven't noticed any problems related to eating more on exercise days, less on other days. YMMV. I haven't sought out any research relevant to this question, but I haven't stumbled over anything suggesting it's a problem, FWIW.

    One observation: You probably have a long run average level of estimated exercise calories (calculated over many weeks to months, if you have the data). You could use that to estimate your typical TDEE, and monitor the scale to watch the long run (multi-week) results, using those results to adjust if necessary. As another option, you could set your goal calories based on your sedentary estimates, log your exercise, and strive to hit your exercise-adjusted calorie goal over a week-ish. (MFP's phone/tablet app will let you look at 7-day average calories, either gross or net.)

    For sure, if you have some occasional ultra-high exercise calories (from riding centuries or something), there's absolutely no need to eat every single one of those calories the same day. You can bank some of them, eat them during the recovery days (or whenever).

    It's your plan: Make it work for you.

    Myself, I actually eat slightly (100-150) under my estimated maintenance calories most days, because I like to indulge occasionally. I haven't noticed any ill effects on performance from those under days. (I do notice a little higher resting heart rate, and maybe a little next-AM sluggish feeling after a super-indulgent day/meal . . . but I'm OK with that, and this one is my plan ;) .) I do see my scale weight jump after indulgences, and drop in between (mostly water weight effects). Some people would dislike that. I don't care: I watch my weight trend.

    My point is that you can try variations, see how you feel, and find your best plan, the one that keeps you happy, in the weight range where you want to be, and performing athletically in the way you'd like. There's no cookie-cutter universal right method, because we're all individuals with different preferences, strengths, limitations, etc.

    P.S. I agree that 1770 seems low. One person's experience tells us nothing about the next person's, but the demographic differences between you and me are pretty major, so I'd expect a similarly significant difference in calorie needs. I'm female, age 67, 5'5" (165 cm), around 130 pounds (59kg) lately, retired/sedentary (or close to it) outside of intentional exercise because retired, and my "slight deficit" base calories are 1850/day. With exercise, actual average TDEE seems to be somewhere in the lower 2000s, maybe 2200 or so. (That's at least 300-500 above most calorie calculators' estimates for my demographic. One reason is estimated body fat percent around mid-twenties, when average for my bodyweight in my demographic would be more like mid-30s percents.)

    I'd also emphasize the importance of good overall nutrition, including but not exclusively adequate protein. Fats, micronutrients, phytochemicals and pro/prebiotics can also affect performance and health.

    You can figure this out. It may not be instant, but as long as you don't let your weight increase lots, or let weight/energy level get too low, you'll be fine. Just keep moving the dials until you find your best approach.

    Best wishes!

    When you're in maintenance, you usually end up needing to make adjustments based on your individual calorie burn. Some of us burn more than the average, some less.

    I've been maintaining for about 10 years. I'm a runner and walker mostly, but do some other things on occasion. I get at least an hour of strenuous exercise 5-6 days a week. Aside from my deliberate exercise, I am mostly sedentary. As a 65+ female, 5'5" and 123 lbs., MFP gave me 1400 calories. I was losing weight with that so I increased it to 1600. Still too low, but it gave me a goal that I aim toward but don't worry when I miss. Reality is I need about 1800 net calories to maintain my weight, but I like having flexibility. On days I exercise more I eat more, but I let hunger determine how much more. If I'm hungry I eat. If I'm not, I eat to goal. I look at the weekly reports to see how I am doing on average. Mostly I look at the scale to see whether I'm eating too much or too little. If I don't like what I see, I adjust.

    You've lost weight and now you want to maintain. How many calories on average were you consuming or scheduled daily to accomplish that? Why not just increase the amount you consumed incrementally, until your weight stable, am I missing something here?
