Welcome to The Visible Embryo, a comprehensive educational resource on human development from conception to birth.

The Visible Embryo provides visual references for changes in fetal development throughout pregnancy and can be navigated via fetal development or maternal changes.

The National Institutes of Child Health and Human Development awarded Phase I and Phase II Small Business Innovative Research Grants to develop The Visible Embryo. Initally designed to evaluate the internet as a teaching tool for first year medical students, The Visible Embryo is linked to over 600 educational institutions and is viewed by more than ' million visitors each month.

WHO International Clinical Trials Registry Platform
The World Health Organization (WHO) has created a new Web site to help researchers, doctors and patients obtain reliable information on high-quality clinical trials. Now you can go to one website and search all registers to identify clinical trial research underway around the world!

Becoming obese is easy in the world we find ourselves in, filled with cheap food

WHO Child Growth Charts

What Is Your BMI?


Losing Weight Is Hard, Keeping It Off Harder

Obesity is implicated in almost all of our health problems, from cancer to heart disease to diabetes to arthritis to cognition. And, once you've become obese, if you succeed at losing weight, you'll find that your body has a metabolic drive to regain those pounds

If you think everything around you is conspiring to sabotage your weight loss, you're onto something, said James O. Hill, director of the Colorado Nutrition Obesity Research Center and the keynote speaker at the University of Illinois's Division of Nutritional Sciences recent Nutrition Symposium.

"Since World War II, we have engineered an environment in which food is cheap and always available, and physical activity has declined because of cars, computers, and countless hours of TV watching."

Becoming obese is a natural reaction to the world we find ourselves in, he said.

If you want a quick picture of how the world has changed, compare members of the Old Order Amish faith with today's typical American. Amish men take 18,000 steps a day; Amish women take 14,000. The average U.S. male takes 5,940 steps, the average woman 5,276, he said.

"Now the fastest-growing segment of our population is adults with a BMI over 50, the average American gains a pound a year, and childhood obesity has tripled--and kids don't grow out of it," he said.

Obesity is implicated in almost all of our health problems, from cancer to heart disease to diabetes to arthritis to cognition. And, once you've become obese, if you succeed at losing weight, you'll find that your body has a metabolic drive to regain those pounds, he noted.

So what can someone who's fighting the flab do? The news isn't good. "The more weight you lose, the more you'll have to work to keep it off. You have to be active. If you're active, you eat less," he said.

Insights gleaned from the practices of members of the National Weight Control registry, of people who have lost at least 30 pounds and kept it off for a year:

1. Consume a reduced-calorie, reduced-fat diet.

2. Engage in high levels of physical activity (60 to 90 minutes a day)

3. Limit their TV viewing.

4. Use a high level of dietary restraint (know how to say no).

5. Weigh your self frequently (and if you gain 2 or 3 pounds, do something about it)

6. Maintain dietary consistency.

7. Eat breakfast.

Successful weight-loss maintainers often link their dietary behaviors to other personal values, he said. "They use walking as their spiritual time or they walk as a way to connect with friends and family."

And many of them have made major changes in their lives to support their weight loss, including changing spouses, their circle of friends, and where they live, he said.

On the whole, Americans are not good at making good choices for the long term, he said.

"If someone is going through a fast-food drive-through and they know they should make a healthy choice, with the reward being that they won't get heart disease 20 years later, it usually isn't going to happen. The choice that's getting their attention then is whether to supersize their meal," he said.

But small choices do matter. Eating 100 fewer calories a day will prevent weight gain in adults, and a reduction of 33 calories a day makes a huge difference in weight gain in children.

He praised companies that practice stealth health: Disney for putting veggies and milk in kid's meals unless they're asked for substitutions and Starbuck's for switching to low-fat milk in all their beverages.

He encouraged restaurants to reduce portion size by 5 percent. "No one would notice it," he said.

Also, to increase activity in adults and children, no student should be dropped off less than 500 feet from school, he suggested.

Citing recent research on exercise and cognition, he advocated a push to convince schools that healthy kids learn better, that weight control will improve test scores.

And, because there's evidence that better health means greater productivity, employers should make wellness an expectation and provide a way to exercise and purchase healthy foods on site, he added.

Finally, Americans love a bargain--that's why they love supersizing. Why not leverage the psychology of the deal? If Walmart announced a promotion, saying that for every 2,000 steps you took in their store, you got a discount when you checked out, you'd find Walmart walkers who put things in their cart as they traveled instead of mall walkers hiking past closed stores, he predicted.
