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.

Disprove The LAW of Thermodynamics.
You can`t.
Anybody can eat Krispy Kreme and get ripped and look awesome, if you know what you are doing.
You don`t need cardio either.

ROFLMAO I love that.

Like I said before, this method is nothing new. THe problem is you are cutting your 1 krispe creme in half and eating 1 tablespoon of ice cream. Most people will sit and eat the whole box once they start.

The first law of Thermodynamics is the one about conservation of energy.
You can not "Get ripped and look awesome" just by eating Krispy Kreme. Unless of course you choose their alternative menus that don't include Doughnuts.
Gaining quality muscle is about eating quality foods. Losing weight can occur on a diet of just doughnuts, Sure. But who simply wants to "loose weight"? We want to be healthy also, And you won't be healthy with a diet consisting of nothing but Doughnuts.
If you are 250lbs and are extremely obese and generally consume 6,000 kcalories a day and you suddenly change your diet to nothing but Doughnuts and only consume 3,000 kcals a day of doughnuts then you will lose weight. But this will also damage your health.
Gaining quality body mass as in muscle mass requires a lot more nutrients than you could possibly find in an all Krispy Kream Diet.
Moreover, Adding cardiovascular exercise to your routine not only improves your health but it also makes it a lot easier to lose that extra unwanted body fat.

Yes you can if you are in a caloric defecit!

Your post has TOO MANY flaws to point out.
-

It depends on your definition of "looking awesome". Someone who lives on krispy Kreme diet will have numerous health issues aside from the fact that they won't have much muscle mass because of the nutrient deficit.

Yes, but Adonis is eating meat as well from subway, or mcdonalds usually protein!

You possibly cannot think that eating 300 lbs of meat a year (350 grams of protein a day)
To gain 48 ounces of muscle is optimal. DO YOU?
That is a GIANT RED FLAG of the futility and ineffeciency of taking in protein like that.
-

I don't know what his diet is. I was just addressing the facts about an all doughnut diet. Also it should be pointed out that eating that much fast food is just asking for cardiac arrest. You can have high cholesterol levels even if you aren't obese when your diet is Mcdonalds everyday.

I gain a lot more than 3lbs of lean muscle a year, I don't know about you. Maybe you have naturally low testosterone levels???

Would it be an issue when you are only eating 1600 calories like he is though?

The human body can only absorb and synthesize so much protein. The rest is passed out of your body via urination. .4 grams of protein per kg of bodyweight is more than enough.

One measily multi-vitamin consistantly every day will take case of a persons needs if taken everyday on a consistant basis.
Of course, no-one lives on a diet of doughnuts but the majority of the Americans live on fast food and microwave crap. But even with that, its not the actual food, its the large amount of food eaten at irregular times putting the body into mini starvation mood causing the body to automatically store fat.
It is better to have healthy food around but if you are hungry, its better to simply reach for an ice cream cone than to put your body into a catabolic state and cause it to store food when you finally do eat
-

Would what be an Issue? Cardiac problems from such a diet even on 1600 calories a day? Yes.

How many grams do you get a day? I am on a much lower protein diet myself now.
-

Good So you proved me Correct.
I get 30 grams at least.
-

Me personally? Probably less than 80 grams a day on average.

There is more Cholesterol in a Chicken Breast than in a Big MAC.
Look it up.
-

What do you weigh? If you weigh 200lbs then at .4/kg you should be getting at least 170 grams of protein a day. The .4 grams per kg of bodyweight only applies to lean mass.
-

Look it up.
It definitely depends on the Chicken Breast.
-

You act like Cholesterol is a completely bad thing. Do you even know it's role in human physiology?
-

how do you figure 170?
It would be 36grams if it's .4g per Kg
-

Of Course!
That is why I don`t care about my Cholesterol intake one bit!
I just use it to counter when people tout that a chicken breast is superior to a Big Mac in terms of being better on Cholesterol levels.

350 grams of protein = 1400 calories = :P
100 grams of Olive Oil = 900 calories
Fat from rinsed beef (can't rinse it all away) = estimated 75 grams = 675 calories
Carbohydrates (The body needs a minimum 100 grams of carbohydrates for proper brain function) 400 calories
Total Calories = 3375 calories..... :o :P
5 McDonalds Big Mac's = 2880 calories
See the picture now, folks???

Vince Just proved that eating 5 Big MACS a day is BETTER than eating DANTE`s BULLSHIT DIET.
HAHHAHAHAHHAHAHAHAH I love it.
-
how do you figure 170?
It would be 36grams if it's .4g per Kg
You're right.
I botched the math. I meant to say 1 gram per kg of bodyweight. Meaning a 200lb person should consume about 90 grams of protein a day not 170.
-

You did the math wrong.
According to that I need about 30 grams of protein.
That is about how much I get.
You are good in proving me correct.
-
You're right.

Yes that seems like a reasonable amount to me. You can get 90g of protein without even trying eating decent foods.
So many bodybuilders think that protein is some magic substance that your body can never get enough of.

Of Course!

No, I did the math wrong. 30 grams a day isn't enough for a 200lb person.
-
Bjorn from what source did you get that formula for protein?
-
You should care about your cholesterol Intake. If you consume foods with high (LDL increasing foods espically saturated fats)cholesterol then you're setting yourself up for heart problems in the future.

HAHHAHAHAHHAHAHAHAH I love it.
I was actually being conservative on the diet as I did count other stuff.
But this should wake everyone up.... ;D
6 KFC Original Recipe Chicken Breast = 2280 calories

Vince I had 2 kfc buffalo snackers yesterday, 520 calories total.

Vince,
Do you realize that We can turn you into a ripped beast simply by you eating the foods you love?
Give it a try. Dieting will become the easiest thing you have ever done.
I am Excited to see you try it Vince.
How shocking will it be when you are 3 percent from eating Mcdonalds Hamburgers!!!
Vince you have been enlightened. Now go out there and do it!
I am with you 100 percent of the way.

Sorry, but my calorie intake is currently much lower than that, I'm an endomorphic so I can't get ultra-ripped but I can be thick and massive and that's what I'm going for onstage at the Mountaineer. My abs are coming in nicely and the Quads have striations but the only thing I'm concerned with getting the waistline as lean as possible so makes my arms much larger. When my arms are pumped, they measure at almost 19 inches and that's what I'm counting on.
