Even if I'm properly and thoroughly hydrating, I tend to get headaches more when I exercise. Anyone else?

    Occasionally, but my biggest issue is low blood sugar during a workout. I have to make sure to eat a protein bar with a lot of carbs right before exercise.

    Not sure if it would matter... but are you eating at a deficit and size of deficit? How close to the exercise are you eating (before/after)? Length/duration/intensity of exercise? Trying to figure out if you may have an energy availability issue during the exercise. And in to see what others have to say :smile: Hope that the headaches are well controlled and not too onerous!

    Could that be my trouble? I try to always workout "fasted" except for coffee with cream/sugar.

    Thanks! Not too onerous but frequent especially around TOM which may play into it. I try to eat within 2 hours of working out. Intensity is hard but I keep hydrated. I saw my doctor about this very thing probably a decade ago, his response was that I was working out too hard which I felt like was a curious explanation.....I haven't been working too hard as I've was sick all week. Today was is my first workout since getting better.

    Also, I recently readjusted my weight loss to 1lb per week. And I've been instructed to eat back all exercise calories. I feel dubious about that point because like today I did a high intensity aerobics class and burned over 430 cals on my Fitbit. Possible?

    Just be careful not to conflate complete burn with ADDITIONAL burn because of the exercise.

    I would look at your Fitbit's FINAL NUMBER for the day and compare that to the activity level you selected on MFP.

    That's the "extra" calories you can actually eat assuming accurate tracking of calories in, out, and you being close to the mean as most but not people will be.


    **** **** ****

    Burns are calculated as multipliers of your BMR on both Fitbit and MFP.

    Fitbit "educated guesses" an expenditure based on the activity it detects and averages over 5 minute increments. It takes the average of the 5 minutes and assigns it a single MET value and thus comes up with the caloric expenditure for the time interval.

    A high heart rate, or increased heart rate that is not associated with steady state activity has the potential to fool it a bit.

    But you're playing at the margins a bit, as horseshoes and hand grenades are usually good enough for our purposes and already more "accurate" than what most people are dealing with when they try to calibrate by hunger and instant scale results as opposed to metrics and weight TREND results.

    So. The important thing to consider is that MFP is already assigning you a 1.25 BMR (or 1.4, or 1.6, or 1.8x BMR) number of calories per minute of that exercise.

    And it gets a little bit more complicated too if you just look at the activity in isolation. MFP gives you that 1.25 no matter what you're doing. Fitbit is giving you 1.0 when it doesn't detect anything but 10 when it is detecting hard running for example. They both have errors but usually non biased errors cancel each other as opposed to reinforce each other. So you're trying to interleave an isolated detection of just the activity itself. I think that this will have the potential for a higher percentage of error than looking at the whole day's calories and going with that (this second thing is what MFP-Fitbit integration does)

    Specifically for your class, you're saying you burned 430 Cal or a bit more than 7 or 8 Cal a minute depending on duration. Many people's BMR would be AROUND 1.0 Cal a minute (1440 minutes in a day, average American woman BMR 1400 / man 1800). So this would be around an 7-8x activity... and aerobics, high impact has a MET value of 7.3 (aerobics low impact is 5.0)... within the range in other words assuming you don't have an abnormally high heart rate while exercising.

    Thus I don't see any reason without details as to why we would call the value implausible. It looks to me as if Fitbit detected aerobics and assigned to it the generally acceptable activity factor for that activity and duration. Or at the very least something very close to it unless your MFP BMR (https://www.myfitnesspal.com/tools/bmr-calculator) would make the value implausible.

    Do remember that apparent accuracy depends on both sides of the ledger (including accuracy of food logging). Hence the adage to adjust after 4-6 weeks (so as to include a full monthly hormonal cycle) based on logging and weight trend results (with fitbit it is trivial to connect trendweight.com)

    I would consider cream and sugar to be energy sources depending on their quantity. In any case, things may also improve with your new, lower, deficit.

    You could experiment with having something a little more carby prior to workouts, see if that helps. Even just a piece of fruit.

    I do. I think I strain my neck when I lift. It helps if I wear a low ponytail vs high because when I need to lean back I have better neck posture. I used to wonder if La Croix caused headaches but couldn’t find any research. I got them so often day after a hard workout. I just switched from heavy lifting to Orange Theory. I am curious if it changes.

    The only headaches I get are the awful ones I get if I don't eat within about 15 minutes of getting up in the morning.
    If I do anything the least bit active before eating, my morning is miserable. I wouldn't even try to exercise before eating! I've always been like this. Must be low blood sugar, I guess.

    Yes.. but not from exercise.

    Either from stress or hunger

    I get headaches if my blood sugar goes too low. Maybe eat something with a few more carbs and fiber. Fruit is a good idea but also something like a bowl of oatmeal or a slice of whole grain toast with a bit of butter or peanut butter for a bit of protein.

    So, since the exercise cals given are "complete" burn does FB then subtract those extra "existing" calories from my main FB calorie burn? Therefore the calories won't be represented in 2 ledgers ( exercise and main)??

    If I eat back 100% of the calories and those existing calories (my activity is set to sedentary) aren't subtracted, it could lead to weight gain.

    Fitbit takes care of its own accounting and it comes up with a final figure for the calories you've burned to the end of day (TDEE)

    That is what it records, historically, as your burn for the day.

    That is what it synchronizes with mfp at 23:59, assuming integration is enabled and working properly.

    The individual activity numbers are just informational and can be ignored in terms of calculating an eating goal.

    I find it easier to just automate within the limits of the tools. It sounds to me like you're trying to potentially manually override.

    I would not for example look at an exercise on Fitbit and manually enter it as an exercise on MFP. If you were to do that, you would potentially back pollute your Fitbit data if you ever were to enable integration. This is because this manual exercise will override what Fitbit detected during that same time period. Also, as mentioned, the burn for the exercise will be overstated by at least 0.25 BMR per minute Calories because of your mfp sedentary setting.

    There are two different types of numbers that are called the same on the MFP app.

    An exercise burn directly measuring an exercise. This burn is gross while you probably want the net value. It is a major reason for the "eat most but not all your stated exercise calories" advice.

    An exercise burn that is related to fitness tracker - MFP integration. This number is a net number of extra expenditure your tracker detected when compared to what MFP expected you to burn based on your stated activity setting.

    This number will keep changing and will only be final at midnight. If everything is working properly (logging, you, the universe) these calories can all be eaten while meeting your stated goals.

    TLDR; of @PAV8888's post, trust your Fitbit, and the adjustment that it sends over to MFP. You don't need to worry about anything else.

    I agree with this.

    Try deep breathing in and out when doing exercises, might be the oxygen circulation flow, we sometimes tend to forget to breathe properly when engrossed with exercise routine. Just keep in mind, hope it helps.
