When you're used to eating at specific times throughout the day, your body learns to anticipate food, making its digestion and metabolism more efficient. In fact, a study at the University of Nottingham in England found that women who ate at predictable times consumed 120 fewer daily calories overall and burned them faster than those who ate haphazardly. Researchers think the schedule may help your body produce the right amount of insulin as well as hunger and fullness hormones so you don't overdo it.

Laugh to loose weight!
According to Vanderbilt university in Nashville,when people watched a humorous television program, they had a 20 percent increase in heart rate and resting metabolism. Laughing uses a lot of energy because it recruits a variety of muscle groups, most importantly your abs. Laugh for just 15 minutes a day and that metabolic boost could add up to 14,600 more calories burned per year. That's about 4 pounds!

Eat Breakfast, Loose Weight.
When you wake up, your metabolism is usually at its highest, so it's smart to have a healthy, hearty morning meal. Not only will it keep you energized throughout the morning, but you'll also be able to burn it off more easily throughout the day (because you'll head off splurges the are caused by being famished), making weight loss more attainable. In fact, obese women who ate a 600-calorie breakfast shed about 40 pounds in eight months, whereas those who ate smaller morning meals experienced only a 9-pound loss, according to a study conducted at Virginia Commonwealth University in Richmond. The secret? Breakfasts that contained a mix of protein, which helps keep blood sugar levels steady and staves off hunger, and carbs, which satisfy while helping to protect you from cravings later on.

Paint Roofs White to slow climate change
US Energy Secretary Steven Chu said the Obama administration wanted to paint roofs an energy-reflecting white, as he took part in a climate change symposium in London. The Nobel laureate in physics called for a "new revolution" in energy generation to cut greenhouse gas emissions.
But he warned there was no silver bullet for tackling climate change, and said a range of measures should be introduced, including painting flat roofs white.
Making roads and roofs a paler color could have the equivalent effect of taking every car in the world off the road for 11 years, Chu said.
It was a geo-engineering scheme that was "completely benign" and would keep buildings cooler and reduce energy use from air conditioning, as well as reflecting sunlight back away from the Earth.
For people who found white hard on the eye, scientists had also developed "cool colors" which looked to the human eye like normal ones, but reflect heat like pale colors even if they are darker shades
Simply painting roofs white in warm climates decreases air conditioning bills for those buildings by 20 percent. That's one reason why California has required all new buildings to have white roofs for the past few years.
This new study says that if the 100 biggest cities painted all their roofs white, and switched their road materials to lighter colors (concrete instead of asphalt) it would reflect enough light and heat back into space to entirely offset the warming of the last few decades.

Vitamins found to curb exercise benefits
Nicholas Wade NYTimes May 11, 2009
“If you exercise to promote health, you shouldn’t take large amounts of antioxidants,” Dr. Ristow said. A second message of the study, he said, “is that antioxidants in general cause certain effects that inhibit otherwise positive effects of exercise, dieting and other interventions.”
The effect of vitamins on exercise and glucose metabolism “is really quite significant,” said Dr. C. Ronald Kahn of the Joslin Diabetes Center in Boston, a co-author of the report. “If people are trying to exercise, this is blocking the effects of insulin on the metabolic response.”
