I eat a lot of fiber throughout the day. Hard rye bread, oatmeal and a ton of fruit. May explain the high evening weight and the morning post-crap lows.

Weighed the same this AM as yesterday but noticed a one-pound drop tonight from last night's high. Curious to see if tomorrow's am weigh-in will reflect that. I'm riding to work tomorrow. So, if I lose a pound before then, it bodes well for my weekly weight loss goals.

It is on something like a 10 day pattern for me, 6 weeks in a row I was right around 2.9 lbs a week, then it shifted to 1.2 one week and 3.5-4.0 the next.

Do men have weight fluctuations like women do? I really should weigh myself weekly since my weight goes up and down all week.

I would not think we have a monthly fluctuation.....
I can post up some of my numbers for the last 2 weeks...

It seems like it will hold, hold, hold or maybe rise a touch, then drop :-)

Date,weight,7 day average,waist,loss for week, the BOLD numbers in the average are when I posted to Myfitnesspal.

I weigh more in the morning even after the usual poop. It isn't uncommon to retain as much as 3 lbs of water if I splurge on fries or Chinese food the evening before. And yes, I also weigh myself each day but don't consider it torture. Being human we want to see some progress as we undertake a worthwhile project. My most reliable weighing time of the day is after my ride providing I consume my usual16-20 ounces of fluid during the ride; no use fooling oneself holding off on drinking just to see a temporarily lower number on the scale.

I typically do not eat after supper, or drink much after 8PM. So, it makes sense that my weight falls off overnight.

Working second I shift eat at 7am, 11 am, 4pm, 6pm, and 1030PM. I deposit solid waste at 7am, so for me anyway right after that is when I weigh.

I always weigh myself in the morning, right after I wake up, with no clothes(usually before hopping in the shower). I use MFP as well but I never mark a weight decrease(or increase) unless its been 3 straight days of it on my morning weigh-ins. I also like to weigh myslef at night to see how much it has fluctuated during the day. I know my weight will likely go back down after I sleep. It's not so much torture for me but just to get an idea of how my body is responding to the diet and exercise. So far its been working good.

Yep. Can't weigh yourself enough if you really want to hone in on what works and what doesn't, IMO.

...besides it's nice to see the daily max not exceeding what only recently was my morning min.

i don't typically weigh at night, but when I do, I'm typically 3-4 lbs heavier than the next morning. No reason to think 5 lbs is unusual.

For that matter, even with a consistent diet, my morning weight varies by 2-4 lbs each day, so a 5 lb range is nothing to sweat. Log your weights and pay more attention to long range trends than any single weigh in.

I still think weighing yourself once daily under the same conditions is more than enough.

If you are truly taking in only 2,000 calories a day the weight should be falling off you...there would be no need to be so obsessive-compulsive.

I agree 110%.....there is no way to "gain" weight if one is running at minimum a 1000 calorie a day deficit.....my weekly and monthly numbers say I am running more than 1000 calorie deficit...it is however nice to have some basis of comparison when it comes time for the dreaded Dr. Office weigh in :-)...which somehow always adds 10 lbs :-).

Keep in mind also that many (most) cycling and exercise apps tend to overestimate the number of calories burned. If you combine this with a natural tendency to underestimate food calories, it's easy to show a deficit when there is actually a surplus. Unless you're using a power meter and a scale, you should always view your numbers as suspect. I got the best results when I tried to underestimate exercise and overestimate food. Combined with a daily weigh in first thing in the morning (after using the bathroom), that gave me a good picture of how I was doing, but I still have to allow for daily variations in response to stress, muscle recovery, sodium, carbs, sleep, or other factors.

Yes most aps are WAYYYYYYY off for most forms of exercise. I eat 100 cals of exercise back at the most, today Cyclemeter linked with my Wahoo TICKR wanted to give me 1400 cals for 21 miles, Wahoo gave me 1453. I will have to fine tune the exercise credit once I reach my target weight. One lady I know who time trials in the UK trains about 19mph on a road bike, or races at 24-25 on a trials bike, she factors in 400 cals an hour for training or racing...it is looking like that is maybe a little low...but it is not miles off though.

Running a 7 day average really shows what is going on, the average consistently drops :-).

I have plans to buy a power meter right about a year from now, I will graduate to a road bike the first week of October, drop another 70 lbs by mid summer, and that will give me a solid year of training, a power meter will start to make sense for me NEXT year probably :-).

FWIW, using a HRM and power meter, I burn around 600 calories an hour if I'm pushing (i.e. hard race, major headwinds, and/or a lot of climbing), 400-500 calories an hour at normal pace (running 75-80% effort, flat or rolling hills), and it can get down to 200-300 calories an hour on a bonafide recovery ride or pleasure ride with the wife. obviously, your numbers will vary, but they shouldn't vary more than 100-200 calories per hour beyond these.

Yea that sounds quite reasonable, I know Black Wallnut uses an HRM with his Garmin computer and eats back a lot of his exercise calories and has good success with that whole deal, even without a power meter.

I am looking at these rollers here maybe mid october...

https://www.sportcrafters.com/produc...ve-pro-rollers

And there is a review posted on their page where a guy posted some data from riding a bike equipped with a power meter on the rollers.

https://www.sportcrafters.com/blog/t...ve-pro-rollers

That might give me some very useful information before I actually buy a power meter......right now I have no idea what my output is.

This is the key if you must weigh all the time. Record your weight once per week and see the overall trend. Daily recordings will only frustrate you.

My wife more or less weighs once a week, but she did it on sat and sunday last weekend, she was happier with the Saturday number :-).

I weigh daily. That's what helps keep me focused. I don't fret about the fluctuations unless they are a certain amount. Lets me know I overdid it in some way. Sometimes I'm ok with overdoing it but I want to remind myself that I need to be back on track starting right then and there. I don't beat myself up on it however. I just see the number and move on.

@300 lbs, I have often seen a 4 lb+ difference between morning and evening in both directions.

I try to consume all my water by 5 pm for the day. so I have lots of water floating around in me if I weight in after I get home vs the morning where I had little water and ate a small amount with little salt the night before. I might be 4 lbs heavier in the evening vs morning.

On the flip side, I have a more relaxed eating habits on the weekends which often provides more salt in my diet and i end up holding a lot more water and I often see a 3.5 lbs + loss from morning weigh in vs evening weigh in on Mondays.

Are you using a HRM? It's not as accurate as a PM, but it'll get you closer than the straight miles/speed algorhythms most of the apps use.

I see people post this and I could not disagree more. Given that you can keep your net calories relatively consistent and still see a daioly variance of 2-5 lbs, weighing weekly has the potential to be far less accurate than a daily weigh in.

Consider: My last 7 weigh ins have been 165, 166.2, 166, 164.4, 166, 167.6. Looking at that, it's pretty easy to see that my weight is hovering a lb or two around 166. Given that I have a little over 3 years of daily weigh ins logged, I know that the variation I saw this week is typical for me. There's no reason to think the 167.6 is anything other than normal variation, possibly due to a salty/carby dinner.
On the other hand, if I weighed once a week, I'd look at 165 and 167.6 and could conceivably draw the erroneous conclusion that I'd gained 2.6 lbs, and could spend teh next week trying to figure out where I consumed that extra 9100 calories!
More data is good, as long as you maintain consistent conditions. Daily, naked, and first thing in the morning after using the bathroom is as consistent as you can get without getting into the lab.
