To clarify the math.

If you hit your goal exactly, with 0 calories left over, that means you have a 500 calorie deficit for the day. It's already built into your 1 pound per week goal. 1 pound per week = 7 days * 500 calorie deficit per day = 3,500 kcal weekly deficit, the amount of calories in a pound of fat.

Yea. I figured (today) that's how it's working. And explains why I'm starting to feel a bit lightheaded and weak. It appears junkfood was keeping me alive lol :o . I gotta find some more food I think lol.

I would have suggested just tracking what you eat normally for a few days first, before you try to make changes based on the data.

I was "blessed" with a hungry temperament. Eating to satisfy boredom, or "addiction to sugar" aren't my problems. One of my coworkers lost half his belly by buying smaller bags of chips, he said he'd open a bag and eat until he finished it. That doesn't work for me, I need to eat a good volume of food to feel satisfied. So I do a yogurt for breakfast every morning, I get a lot of food for not that many calories, and there's lots of protein and fat in it to promote a feeling of satiety. Because my problem is hunger, so I do things to make me feel not hungry.

I'm sure you'll notice a pattern, too, and find some little tricks to help address it.

Yup. that's really all that happened yesterday and today is that I definitely noticed a pattern of supplimenting an overall healthy diet with a certain amount of junk food, or at least random, easily accessible food. I don't think I realized how much of my diet this made up until I cut it out.

We all hate the fixed gear guy because you nerds love your gears and think you’re so cool shifting and clipping in, and wear spandex with sewed in diapers and let’s also point out choosing the easiest gear possible to ride in, I see you out there. Option B youre too stupid to understand my initial statement. At no point did I request advice on my bike.







You do know that there are singlespeed/fixed, and fitness subforums, right? There's no need to tangle yourself up with us clipping in, diaper wearing, shifting nerds. Good luck with your beard and PBR.

I certainly wasn't starving myself. It really does seem like if you're constantly tracking what you're doing...you're less likely to do something stupid, or negligent in regards to your health/fitness. I suppose this should be obvious lol. But it doesn't really seem to be in practice.

MFT grossly over estimates calories burned by cycling. It says my 45 mile commute burns 750+ calories, where a power meter actually measures 375.

So your deficit may be wayyyy less than you think.

Truth. If you have a PM and are on Strava, you can synch MFP to use the calorie number from Strava.

I think the exercise total is pretty close for me. I've got a 40 minute commute that covers 7.5 miles through the city. Strava pretty consistently logs ~350 calories for it. A bit more or less depending on how fast I take it. I'm a shade over 190lbs; The calories seem about right.

Their exercise database is worthless.

I have my stuff sync to MFP from Garmin Connect. I use a power meter, and Garmin sends the correct info* to MFP.

You can have Strava feed MFP your calories, too/instead. I don't know exactly where to find it, but there's an "apps and devices" link somewhere, that's how you set it up.

* Note: I think using a power meter gives you a slightly bigger deficit than you expect, because MFP's system expects BMR calories to be part of the total. But a PM only measures the energy you put into the bike; if you stayed on the couch it would say zero.

Abe_Froman 08-08-18 03:18 PM

Either way...one day of this has sort of made me realize actually that I'm under eating during the day, and then attacking whatever happens to be in the fridge when I get home from work and say goodnight to my kid. It's often well after 9 by that time.

Sounds to me like the problem is just that the fixed gear doesn't work for the terrain you ride.

I live in Atlanta, very hilly, and it baffles me I see people on fixed gear or single speed bikes, struggling.

I know, I know, all your hipster friends have single speeds as well, and that's what's cool. But there's nothing cool about walking your bike up a hill buddy.


im 40 years old, I’ve had this bike for over 10 years. In no way do I qualify as a hipster dufoos. But since we are being judge mental idiots, you’re in Atlanta, are you a criminal or or redneck idiot? Both is very possible

Bicycle Speed (Velocity) And Power Calculator

100 watts (hands in the drops)

150 lib rider + 20 lb bike -> 16.3 mph
175 lib rider + 20 lb bike -> 15.9 mph
200 lib rider + 20 lb bike -> 15.5 mph


Can someone please just throw 10lbs of pork chops into their cute little spandex shorts on their next trip? Make sure you insert your Garmin into your corn hole and record all your data. Then, next week on your next ride of course, complete the journey again and report all data back to the forum.

But it it will be totally meaningless. Early on a polite an inteligent man dropped some knowledge that can’t be measured but will surely have the greatest impact. It’s the fact that the weight is coming of your person, your heart will not be working as hard to pump blood to a smaller body.

now to really blow your minds. It’s not that I can’t ride all over and I end up having to walk my bike up hills, how that got blown up is beyond me.

didnt it occur to any of you that I may actually be more efficient oxygen wise in a higher gear? No one mentioned this and I had a chat today and did some research. Different bodies work in different ways. Mashing vs spinning, fast twitch/slow twitch anaerobic vs aerobic.

But I believe I have all the info I need, thanks for the entertainment.

Statistics tells us that you’re far more likely to be wrong than that you’re some sort of genetic freak that excels at low cadence cycling relative to the rest of the world.

Psychology tells us you should probably work on your attitude.

Does this mean that a 200 lb rider that averages 16mph over a 30 mile flat course will average 20mph over the exact same course if he does nothing other than lose 48 lbs?

You walk your bike up hills? :eek:

Ahh, that lower cadence leads to better oxygen efficiency has been known for a long time (and is well documented). There are drawbacks to it and good reasons road racers ride the high cadences but those don't change the fact of low cadence-higher oxygen efficiency.

And re: this forum - most of the time I don't post here because of exactly the attitudes seen in this thread. But I am a pure roadie. Always have been. And I have done over half my road miles on fix gears. Balancing the gear for uphill vs flat vs downhill is a very real part of road riding fixed, (Or stopping and letting your body cool down, change the gear, then have to warm up again.) It's a different game, but just as much "road riding" as what any of you "roadies" do.

Hard men ride fix gears., Don't believe me? Put in a 130 mile day fixed. Ride up and around Crater Lake. Ride the courses of the early Tour de Frances. Do it and come back to me.

I HAVE a fixed gear. And much/most of what you say is true. But it doest change the sillyness or bad attitude of the OP.
