Bad Day - a handful equals a handful

It's a bad day.  All I want to do is grab a handful of something bad and delicious to snap me out of this.  You know what is holding me back?

This handful.

Wowzers

Almost a week since I have ran my half marathon and I have not done any exercise or watched what I eat.  That ends today.  Time to get back on track.

I got my student card yesterday which entitles me to a free gym membership.  I am going to take full advantage of that fact. 

Back on track, back on track.  Get this sh*t done.  Next time I run a half marathon I will be lighter and faster.  Trust me.

I Did It

Today I did something I never did before.  I ran 13.1 miles.  That's right one and all, I completed a half marathon in San Francisco.  The Nike Women's Marathon where my medal at the end was a beautiful Tiffany's pendant. 

My goal was to do it in under 3 hours and not to die.  Mission completion!

More to come later.  I have tonnes of pics.

Run like a girl!!!

The Physics Diet

The Physics Diet



Want to lose weight? Easy! Just remember the first law of thermodynamics: conservation of energy.

by Richard A. Muller

Technology for Presidents

November 14, 2003


Here's an old joke. The dairy industry hires a physicist to improve milk production. After several weeks, he's ready to lecture about his progress. He draws a circle on the blackboard and says, 'Consider a spherical cow.'

I've told this joke many times, but nobody ever laughs -- except other physicists. For the rest of you, I should explain that it is self-deprecating humor. It makes fun of our penchant for oversimplification.

This month I want to talk about diet and exercise for weight loss, and I'm going to oversimplify on purpose. Consider a spherical physicist.

Most dieters are so concerned about second-order effects, such as daily fluctuations in weight and changes in metabolism, that they lose track of the first law of thermodynamics: conservation of energy.

Want to lose a pound of fat? You can work it off by hiking to the top of a 2,500-story building. Or by running 60 miles. Or by spending 7 hours cleaning animal stalls. (It is amazing what scientists have actually measured. This last example is tabulated in the book Exercise Physiology by G. Brooks and T. Fahey.)

Exercise is a very difficult way to lose weight. Here's a rule of thumb: exercise very hard for one hour (swimming, running, or racquetball)– and you'll lose about one ounce of fat. Light exercise for an hour (gardening, baseball, or golf) will lose you a third of an ounce. That number is small because fat is a very energy-dense substance: it packs about 4,000 food calories per pound, the same as gasoline, and 15 times as much as in TNT.

If you run for an hour, you'll lose that ounce of fat and also a pound or two of water. By the next day, when you've replenished the water, you might think, 'the weight came right back!' But you'd be wrong -- you really did lose an ounce. It is hard to notice, unless you keep running every day for a month or more, and don't reward yourself after each run with a cookie.

There is a much easier way to lose weight, as we can learn from the first law of thermodynamics. Eat less.

A reasonable daily diet for an adult is 2,000 food calories. That's 8.36 megajoules per day, or about 100 joules per second -- in other words, 100 watts. Most of that ends up as heat, so you warm a room as much as a bright light bulb. Cut your consumption by 600 calories per day and you'll lose a pound of fat every week. Most diet experts consider that a reasonable goal. Don't drop below 1,000 calories per day, or you might get lethargic. But at 1,400 calories per day, you can easily maintain an active life.

Of course, there is a catch. You'll be hungry.

It's not real hunger–not like the painful hunger of starving people in impoverished countries. It's more of a mild ache, or an itch that you mustn't scratch. To be popular, a diet must somehow cope with this hunger. Weight Watchers does it with peer support. The food pyramid does it by encouraging you to eat unlimited celery. Some high-fat diets satisfy all your old cravings -- and figure you'll eventually cut back the butter you put on your bacon.

Last April, I had once again grown out of my belt. I wasn't grossly overweight: 205 pounds in a six-foot, one-inch body. That wouldn't be bad for a football player, but I'm 59 years old, and the excess pounds weren't in muscle. I had gained a pound a year for several decades. I felt heavy and old. I decided to try conservation of energy. I gave up lunch and snacks.

How to cope with the hunger? I attempted to enjoy it. I thought of the movie Lawrence of Arabia, in which T.E. Lawrence says, 'The trick is not minding that it hurts.' I told myself that the mild ache was only the sensation of evaporating fat. That interpretation has some basis in physics. When you lose weight, most of your fat is converted to the gases carbon dioxide and water vapor, and so you get rid of fat by breathing it out of your body.

Physics works, and I lost weight. By August, I was down to 175 pounds, a 30-pound drop. My belt went from 42 inches to 36 inches. My Zen-like approach to hunger also worked; I found myself declining offers of chocolate cake because I didn't want to lose the sensation of evaporation. I didn't change my level of activity, and managed to maintain my diet while taking trips to Cuba and Alaska -- and during a week-long backpacking excursion in the Sierra Nevada. A key innovation: I kept up the social aspects of lunch, without eating. I watched others gobbling cheeseburgers, while I sipped diet cola. It really wasn't that hard to do. And the mild afternoon discomfort was compensated by several positive developments. Dinner became truly wonderful. I hadn't had pre-dinner hunger for decades. A sharp appetite turns a meal into a feast. No more cheese 'appetizers' for me.

Moreover -- and this may sound silly coming from a physicist -- I was surprised that I began to feel lighter. I no longer walk down streets -- I float. Distant stores seem closer. And my knees have responded to the lighter load. Their aching, which I had mistakenly attributed to aging, went away.

Food is instant gratification. And fast-food chains and gourmet restaurants serve tasty food at remarkably low cost. It is a situation unprecedented in history and unanticipated by our genes. No wonder we are overweight.

Anybody can lose weight. Energy is conserved. Just stop scratching that itch. Of course, you'll have to sacrifice instant gratification. Is it worth it? You decide. Food is delicious and cheap. You might reasonably choose to take advantage of this unique historical circumstance, and decide to be fat.

It's been seven months since I started my diet, and two months since I left it. I've begun eating a light lunch, and having an occasional small snack. I'm still at 175. But I never want to lose the delicious edge of hunger before dinner, or the floating sensation when I walk. Moving takes less energy now, so I have more energy. I no longer feel like a spherical physicist. And for losing weight, dieting sure beats cleaning animal stalls.

One Pound of Fat


Hello, do you know me?
 
If you don’t you should.
 
I’m a pound of fat, and I’m the happiest pound of fat that you would ever want to meet. Want to know why? It’s because no one ever wants to lose me; I’m Only One Pound, just a pound. Everyone wants to lose three pounds, five pounds or fifteen pounds, but never only one, so I just stick around and happily keep you fat. Then I add to myself ever so slyly so that you never seem to notice it, that is until I’ve grown to ten, twenty or even more pounds in weight.
 
Yes, it’s fun being Only One Pound of fat, left to do as I please. So, when you weigh in, keep right on saying “Oh, I only lost one pound.” (as if that were such a terrible thing!) For you see, if you do this you’ll encourage others to keep me around because they will think I’m not worth losing. And I love being around you - your arms, your legs, your chin, your hips and every part of you. Happy Days!!
 
After all, I’m Only One Pound of fat!!!

This is why we are fat: We can't say no

This is why we are fat: We can't say no

Very interesting article.  Its good to know why we love what we love so we can work towards change for the better...

I have been hearing a lot of 'poor me' posts out there.  No judgement - honest.  Go back in my blog, there are a tonne of pity party posts.  I think one of the things that helps me get over it is to realize why I am stuffing crap into my mouth.  The article is a good explanation.  It doesn't tell us how to stop but it shows us the why.

Now is Time to Keep it Off

I cannot believe I won this month.  I guess that is what happens when you are training for a half marathon.  A half marathon I do believe I am ready for now.  I ran an never before accomplished 15K today.  It felt good.  I really should have packed some water with me but other than an aching hop for the last couple of kilometers and one pee break I did pretty good. 

I am hoping not to fall back into old crappy eating ways when I taper and the week after.  I would be okay just to maintain this month.  I will be going to San Francisco for 5 days so I will be eating out.  Plus there is Canadian Thanksgiving this weekend and I promised myself I could have pumpkin pie if I did a 10K run that day.

It funny, knowing that I am doing really good and lost the most weight this month you would thing I would 'reward' myself with something delicious.  Nope not this time.  This makes me want to work harder, not just to win more but to be a better me.
