Study of diets shows what truly counts: calories latimes.com :: 2009-03-12
Researchers compared several strategies - low-carb, high-protein and more - and none came out the winner. They concluded the best diet is a healthful one that cuts calories, consistently. Two decades after the debate began on which diet is best for weight loss, a conclusion is starting to come into focus. And the winner is: not low-carb, not low-fat, not high protein but ... any diet that is low in calories and saturated fats and high in whole grains, fruits and vegetables - and that an individual can follow with for a lifetime - is a good choice for people who want to lose weight.

Weight training is necessary to maintaining muscle mass as you age. (7) Eat a little protein with every meal: It helps build muscle and can also stabilise blood sugar and control hunger.
Frequently asked questions about weight loss surgery thebostonchannel.com :: 2009-03-12
(Q) What are the options for weight loss surgery? (A) There are 3 FDA-approved options: gastric bypass, laparoscopic gastric bypass and laparoscopic adjustable gastric band (LAGB). Gastric bypass involves separating the stomach into a small pouch. This delays the mixing of food and digestive juices from the lower stomach. You feel full with small meals. Studies have shown the laparoscopic version has a faster recovery time. The adjustable band procedure places a ring around the top of the stomach, squeezing down on it to create a small pouch.
10 diet myths busted courant.com :: 2009-02-19
(Myth #1) Don't eat after 8 pm. In reality calories can't tell time. "Your body digests and uses calories the same way morning, noon, and night," explains research dietitian Mary Flynn. Night eaters tend to overeat (which leads to weight gain no matter when it's done) because often they've been eating too little during the day. --- (Myth #2) Eating small, frequent meals boosts metabolism. In reality food intake has a minimal effect on metabolism. Some foods, like caffeine, may temporarily step-up metabolism, but the effect is too small to help lose weight. What most affects basal metabolic rate (BMR) is body composition (muscles) and size.
The pros and cons of fasting latimes.com :: 2009-02-19
Some people are adopting an unusual solution to overeating: they don't eat. At least not at certain times of the day or specific days of the week. Called intermittent fasting, this approach to weight control seems to be supported by science. The practice seems to yield the benefits of calorie restriction, which may decrease the risk of some diseases and even prolong life. Mark P. Mattson, chief of the laboratory of neurosciences at the National Institute on Aging: "In normal health subjects, moderate fasting (one day a week or cutting back on calories a couple of days a week) will have health benefits for most anybody."

In addition, it can reduce the risk of heart disease and diabetes. --- (9) Spice things up: Spices not only make foods taste better without adding hundreds of calories, some may help you lose weight (cayenne pepper boosts metabolism), control blood sugar (cinnamon) and even fight cancer (curry powder).
Calorie restriction may boost aging brains washingtonpost.com :: 2009-01-29
Eating less to remember more might become a new proverb for some aged people. Researchers found that memory and thinking skills improved among healthy, overweight subjects who cut their calorie intake by 30% over a 3-month period. The calorie restriction may boost memory and cognition by reducing insulin resistance and inflammation, which may be associated to age-related cognitive decline. The research also tested whether a increase in unsaturated fatty acids (like the omega-3 fatty acid) would yield similar benefits. These healthy fats have indicated better cognitive performance in rats, but the new study failed to find a similar result in humans.
Just 3 cups of brewed coffee a day triples risk of hallucinations telegraph.co.uk :: 2009-01-29
Drinking just 3 cups of brewed coffee a day can triple the chances of suffering from hallucinations, researchers have discovered. "High caffeine users", those who drink more than the equivalent of 7 cups of instant coffee a day, are at the increased risk. Even moderate amounts of the stimulant can lead people to hear voices and see things that are not there. Previous studies have indicated that too much caffeine can lead to heart palpitations, insomnia and even affect a woman's chances of becoming pregnant. The researchers think that caffeine could enhance the effect that stress has on the body, triggering the hallucinations.

Don't encourage kids to clean their plates or criticize them for wasting food.

Most of these are sources of empty calories.
