Weight Loss Discussion Thread

[Hummers]

I have tried this formula and based on the combined weight of me and the bike, it seems I will finish the MC 1000 just within 7 days.

Oh well.

Right. 86kg on the scales the other week (up from my usual weight of 80kg). Probably something to do with the fact I hadn't been out on the bike for 2 months.

2 months until the Snowdon and Coast 400 with a few hills.
2 months to lose 6kg, ideally 10kg but very unlikely.
2 months to get cycling fit again for a 400km ride.

Gravitational Potential Energy = g*m*h
g = Acceleration due to gravity = 9.81 ms^-2
m = mass in kg
h = height in m

1 kg * 9.81 ms^-2 * 13,500 = 132,300 Joules

So that's about 15 minutes at usual Audax pootling pace (160W power input) for each kilo of weight.

This Much Less Weight    3     kg
Over This Distance    250000    meters
On Hill of Slope    0.054    Decimal
Faster by    2595.70    s
Ahead by    7316.70    m
Frontal Area    0.5    m^2
Coefficient Wind Drag    0.5    Dimensionless
Air Density    1.226    kg/m^3
Weight Rider & Bike    96    kg
Rolling Coefficient    0.005    Dimensionless
Power    160    watts

I assume that the actual climbing on the 1,000km will be 250km of "up"

To get 13,500 metres height gain requires a slope of 5.4%

2595 seconds is 43 minutes 15 seconds is just the time gained on the climbs over the imaginary 250km

I honestly thought it would be more than that!

Enough of this fretting about weight loss; If I deduct the weight of my bike, I can ride it even faster!

The 6kg I've lost equates to 1h15 or so.

If I also lose another 2kg as planned, I've saved 1h40.

I'd be 20km ahead of the fatter me.

Not only that, but my FSA has reduced also (by how much I do not know) which gets me along on the flat a bit quicker.  My FSA was already lower than the model default.

And I've increased my fitness.

No worries.

It was Italian night at the pub last night.

Did I really eat 2 kg of pasta? 

[Chris S]

Hmm... I spot a trend. I've taken my eye off the ball a wee bit these last couple of weeks, and it's beginning to show.

Time for some more deprivation

Factoid from that racing weight book:

 - people lose an extra 1lb for every 11 times they weigh themselves in a year

(Obviously this rule can't be extended toooo far...)

(Obviously this rule can't be extended toooo far...)

hehe I'd have disappeared totally some time in 2008 if you could extrapolate that indefinitely! 

[Greenbank]

On my usual month long plateau when restarting the weight loss exercise. Lots of effort and not much reward this early on...

Second 5-a-side night starting again in a couple of weeks' time. That should help.

[clarion]

Got back down below where I've been since mid-Feb.  All good progress, but I am on steroids right now, which might cause issues for the next couple of weeks.

Weight has gone up by a kilo post Brevet Cymru
Hopefully this is just a blip

[Butterfly]

Finally going down again after a month.

Chocolate's nice, thobut

Increased spring mileage, and decreased junk consumption => lifetime PB, under 23 BMI. (despite no calorie counting, loads of red wine and dark chocolate)

Which still seems silly - allegedly I'm still 6-7 pounds above mid-range. WTF?!?

Well, I think that the issue here is the population has become fatter but the ranges have not changed.  This leads to people's attitudes about normal weight being distorted.  My BMI has never been as high as 23 (though it was close late last year).

[MSeries]

I have lost some weight since I started cycling again after my fractured ischium. I weigh 75kg now, the calculators put my BMI at 21.8

[pixieannie]

Hmmm.  I'm half a stone heavier then I was this time last year.  Steroids for pain relief are partly to blame.  I'm not too bothered but just need to stop diving into the chocolate bowl. 

[simonp]

I'm about the same weight I was this time last year.

In between I put on a stone and was told off for being too fat at the fitness test I did in November.  I did the calorie counting thing, but riding a nearly 1500 miles last month has made that a bit redundant.

Ideally I should be about 68kg so I will have to keep at it.

Chocalate covered pixie:sounds rather tasty

I;d like to be 72kg, I feel best at that weight but it's very difficult to stay at  72 so I don't really try. (Denying myself treats affects my mental state too much) I was weight lifting all winter so I may have increased muscle mass anyway. 75kg is OK for someone my age and height.

There is nothing wrong with 75kg at all.  However I was being compared to elite cyclists, not normal people.  In fact my weight wasn't so much the issue (it was about average for elite cyclists) it was body fat %.  It's that I'm trying to reduce, not muscle mass.  I think the milage I've done recently has developed muscle mass in my legs, however.

[rogerzilla]

Everyone in the office thinks I look fairly thin and can't believe what I actually weigh; my BMI is 24.  I'd like to get it down to 23 for a bit of added climbability, but anything less and I will start to look haggard.  Waist is about 32", chest about 39", so not exactly lardy.  Heavy skeleton, apparently.

I've dropped 3lb in the last ten days on my "don't have another bar of chocolate in the afternoon" diet.

[citoyen]

According to Wii Fit, I'm a stone lighter than I was at the start of January. Mind you, I was the heaviest I've ever been five months ago - just over 14 stone. Even better, I can get into a 34" waist again without feeling uncomfortable.

Target is 12 stone by the end of this year.

When I saw the doctor a couple of weeks ago I asked if she could do a body fat test on me as I thought it would be interesting to see what I am, turns out that they don't do them and rely solely on BMI.
