Actually, we're agreeing. If one begins with the premise that any effect is 0, then there is no way to calculate its magnitude. The first step is to recognize that the effect exists (which is what I was saying), the next is to determine its magnitude (a step I didn't feel like taking).
The last step is pretty much required (especially since the typical thing is to assume it's much larger than it is in reality).
Not really in engineering (which balances the cost of something with the benefit).

Now you're adding additional concerns not present in the original discussion. At any rate, it's impossible to calculate a cost benefit ratio, if one doesn't acknowledge a benefit exists.

I did the second step. See post 69.
It's impossible to calculate a cost/benefit ration without any knowledge of the magnitude of the benefit.

if you cut down a tree in a forest and it falls on you, do you hear it hit?

bwaahahaha. Yes, everyone in the ROAD forum is too stupid to give meaninless advice about weight loss magically making your fixie fly up the hills without spinning out like a madman going back down, so some few in the ROAD forum who actually made the mistake of trying to help you went ahead and answered the question you didn't ask, but the only one that will actually help you both up and down hill, and told you to get some gears.
But hey, stupid is as stupid does I guess.

If BF posters met in real life and acted like they do on this forum .... there would soon be only one, as the rest would have died in personal combat.

So.. you can't handle the hills at the gear ratio you have, yet you are considering getting heavier gear ratio so you don't spin out on the downhills....
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.

Forgive me because you didn't ask. But MFP is a really great tool that makes weight loss as easy as it can be. There's a phone app and a web site, you log the food you eat, it has a database with calories and nutrients. It's kind of a hassle at first but gets easier quickly. It builds or refreshes a sense of how much satisfaction per calorie you get from different foods and that knowledge can help you find a way of eating that works for you. I've lost plenty of weight this way myself.

I actually downloaded this the other day, and used it religiously yesterday. Ended up with over a 1000 calorie deficit for the day...and wasn't really consciously trying to eat less. 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.
That's a pretty big deficit.
Pro tip: When you're on the "what I ate in my meals" page, there's a button at the top with an icon like a pie chart. Click it to get a list of your nutrients for the day, how much protein and carbs and fat you ate In here, you can change from viewing "today" to "this week" and get a better idea of how things stand overall.
Some days you wind up with an unsustainably large deficit, and averaging it across a week is kind of like smoothing your power output on the bike.

Were you eating differently because you're tracking? (The quantum problem.)

And yea a 1000 calorie deficit is at the upper end of anything I think I would like to sustain.
Hrmm but wait. I think it is likely more than that. I've got the app set up to schedule a 1lb per week loss...so I assume a deficit is already accounted for at zero calories remaining for the day on the app?
edit: yea i did notice the pie chart yesterday. I think that HAS made me change my diet a bit. I've been pacing 150 grams of protein yesterday and today...I KNOW that is far more than I normally eat.

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.

. 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.

Ok I see what’s going on here. 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.

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.

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.

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.

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
