My Own Metabolism Experiment

Happy Halloween!

On Friday, I mentioned Alysia’s post about her metabolism experiment. After having considered doing the same thing for a while, I decided to give it a shot. Like Alysia, on rest days I find myself wondering if I’m eating too much so I thought this would be a great way to figure it out. I like knowing numbers and of course, I knew that no matter what, I would compare my number to her’s, but hey, that’s just the name of the game sometimes! Knowing that going into it helped me stay out of the comparison trap.

So how did it go..?

Well, to be completely honest, I was a little disappointed. My day started out strong. I noticed for the first few hours in the morning, I was averaging about 100 calories per hour. I didn’t think that would hold up throughout the day, even though I had some errands to run, but I was definitely surprised by how much it slowed down as the day progressed.

My day looked a little something like this:
7:45 am – Wake up and strap on the heart rate monitor
8:30 am – Time for breakfast!

1:00 pm – Lunch and baking time!

3:00 pm – House stuff.. laundry, dishes, etc.
6:30 pm – Heading out to a fabulous dinner and drinks!

10:30 pm – Hit the hay! Yes, we’re old farts.
7:45 am – Wake up and take off heart rate monitor.

That is usually about the amount of activity I have an on rest day. So while Alysia found that an average 2000 calorie/day diet is about right for her, I’m wondering what I could do to help speed up my metabolism on rest days. I feel like 1700 calories is a decent amount, but I’m always looking to improve!

I also wonder if it had anything to do with having a harder week with my workouts. I felt like the quality of my workouts last week were not up to par and it makes me think that if I had a stronger week of workouts, that maybe the results would be different. I may try the experiment again in a few months to see if anything has changed, but in the mean time, I’ll continue to work on listening to my body and feeding it right!

Food for Thought

Have you ever considered trying this kind of metabolism experiment?

If you’ve done this before, was the calorie burn higher or lower than you expected?

Any tips on speeding up my metabolism on rest days?

Are you dressing up for Halloween?

  1. Glad you tried it out! Honestly, I think averaging 2-3 days would give you a more accurate count. I have weekend rest days where I don’t walk around quite so much, which could definitely make a difference! Just be careful not to drain your battery like I did haha. In any case, 1700 isn’t bad for a rest day IMO. You probably burn much more on days you do work out, not just from the workout itself but when you lift your muscles burn more calories through the rest of the day! Just something to think about 🙂 great experiment!

    • Thanks for the feedback! I don’t know if I could handle wearing that strap for 2-3 days at a time, but I totally get what you mean haha. Like I said, I think it might be worth it to give it another shot in the future when I have a really good workout week and see if it changes!

  2. This is so interesting, and when you last posted about Alysia’s challenge, I got interested in doing so myself! Still have no idea where my heart rate monitor is, though, so I’ll have to find it first. One thing that I think is important to remember is that your body doesn’t consider the “day” a solitary unit – so it’s not that if you burned 1703 calories on your rest day but happened to eat 2000, you would instantly gain weight. It’s more of a fluid metric, so if you averaged out the days that you did a hard work out and maybe didn’t quite make up the calories, it would be more reflective of how your body “thinks.” OK, I know I’m not verbalizing this very well, but my point is not to stress out too much about a low burn on one rest day – I think you’re doing great and it’s just nice information to know! Thanks for sharing!

    • I totally get what you’re saying. I know calorie counting is no good for me so I just have to concentrate on listening to what my body wants and fueling it appropriately. And besides, a negative calorie burn every single day is no good anyway, right? Thanks for your feedback 🙂

  3. I have wanted to try this out for awhile but was afraid it would totally kill my battery! haha Will definitely have to sometime though!

    • It’s tough, especially when there is someone else to compare to! Like I said, starting out the day averaging about 100 cals/hour, I was definitely surprised by it finishing at 1700.

  4. you know my thoughts on this! while i am glad that it didn’t seem to get to you tooooo much, i also know how much numbers eff with my head and i think it’s risky to undertake this kind of experiment. so i’ve decided not to but it’s very interesting to read your experience! and i know from talking to you since then you seem to have handled it well and for that i am so proud of you. keep enjoying that pizza! and now i’m off to read that post. to get me pumped for tonight!
