It is amazing what scientists have actually measured. This last example is tabulated in the book Exercise Physiology by G. Brooks and T. Exercise is a very difficult way to lose weight. 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, food calories per pound, the same as gasoline, and 15 times as much as in TNT. 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, food calories. Most of that ends up as heat, so you warm a room as much as a bright light bulb. Most diet experts consider that a reasonable goal.

But at 1, calories per day, you can easily maintain an active life. 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.

Last April, I had once again grown out of my belt. 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. 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.

Water is the main component of blood and is essential for carrying nutrients to the cells and taking away waste products. If your body is short on fluids, one of the first signs is a feeling of fatigue.

Sports drinks combine water with vitamins, minerals, and electrolytes — substances that help regulate body processes. But these extras won't give you extra energy for ordinary, everyday activities see box below.

To maintain your energy level during a workout, drink an 8-ounce glass of water before you start and another after you finish. If you'll be exercising continuously for longer than 30 minutes, drink small amounts every 15 to 30 minutes. It's impossible to walk into a drugstore or supermarket without seeing shelves lined with "power bars" that claim to boost your energy.

The manufacturers of such products claim that they're superior to candy bars because they contain an "ideal ratio" of simple to complex carbohydrates, along with protein and fat. However, there's no proof that such an ideal ratio exists. An Ohio State University study compared the glycemic index of typical energy bars with other sources of carbohydrates.

The power bars were no better than a candy bar at providing sustained energy. As a service to our readers, Harvard Health Publishing provides access to our library of archived content.

The Energy conservation diet industry hires a physicist to improve milk Energy conservation diet. For the rest Enerhy you, Conswrvation should explain that it is self-deprecating dieet. It makes fun of our penchant for oversimplification. 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.
