If you're choosing a motorized treadmill, you'll definitely want to consider motor power. Generally, larger and heavier motor is, cooler it will run and longer it will last. But don't get burned - you should choose a reputable brand when considering motor power also. Reputable brands tend to use better quality parts than cheaper models that may have heavier motors. So be careful.

And you don't want to buy a treadmill that is going to cost a fortune to fix if something goes wrong - so check out owner's manual before buying to make sure that parts are easily replaced and not too expensive.

Okay, after you've evaluated what you want and need in your treadmill, you can consider cost. Treadmills can start at about $400 (el cheapo models) and run up to around $4,000 (top of line luxury). Basically, you'll have to weigh quality and features you require against what you're willing to spend to arrive at a treadmill purchase that you're satisfied with and will enjoy for a time to come.

In fact, satiety, that "I'm full" feeling, is secret ingredient to weight management. "People don't like to deny themselves. They feel a sense of failure when they deprive themselves."

Broth, soups, and juices, along with whole fruits, vegetables, and grains, are high in fiber and water content, and low in fat and calories. "If you have soup before a meal, it helps control hunger and you eat less," Rolls says. "Low-calorie soup takes edge off your hunger." Just be careful not to eat rich, cream-based soups, they could add calories to your diet, she says.

When You Add Water Rich Foods, You Add Volume But Few Calories

-----------------------------------------

How it works: Water dilutes calories in food. You can then eat more for same calories. When you add water-rich blueberries to your breakfast cereal, or water-rich eggplant to your lasagna, you add food volume but few calories, Rolls explains.

Grapes have more water content than raisins. For a 100-calorie snack, you can eat more grapes than raisins. It's just that simple.

Fat Has Less Water Than Any Food

-----------------------------------------

Fat has less water than any food element at 9 calories per gram, alcohol is next at 7, followed by protein and carbohydrates each at 4, Rolls says.

Want More Examples?

-----------------------------------------

Consider difference between chocolate milk and a milk chocolate bar. A 1 1/2 ounce milk chocolate bar has 230 calories, while an 8-ounce glass of chocolate milk made with whole milk has 250 calories. For about same calories, you get a portion that is five times bigger than chocolate bar.

Add more vegetables, and less pasta and fat, to a pasta dish, and you get more food volume. You see difference, and feel satisfied when you eat it, she says.

Obese people eat more low-water foods than normal-weight people, big portions of meats, full-fat milk and cheese, fried eggs, high-fat desserts, one study shows. They also ate few high-water foods like salads, fruits, skim milk.

Psychological satisfaction is powerful, she says. "We're talking about dietary changes that people can sustain. If fat content is too low, it doesn't satisfy your hunger. If you don't enjoy foods, you are not in long run going to sustain eating pattern. That's where people go wrong, they go too extreme, so they're on same old dieting roller coaster."

Make The Weight Loss Switch

-----------------------------------------

Rolls' theories are right on money, says Hassan. "There's a lot of research to back this up. Foods with high water content take longer to eat, and they generally leave people feeling fuller. People feel better when their plate is full and their stomach is full."

Her advice:

Drink two glasses of water or other non-calorie beverage before a meal.

At a restaurant, either eat a small salad or broth-based soup.

At home, fill up half plate with vegetables, one-fourth with a starch, and one-fourth with protein -- so dominant part is vegetables. If you want seconds, veggies would be choice.

Before going to a restaurant, eat a high-volume, low-calorie snack, fat-free milk, a piece of fruit, a cup of light yogurt. "You won't be famished, so you won't eat a whole basket of chips or bread."

If you get evening munchies, drink bouillon, hot tea, or light cocoa, or have two cups strawberries with light cool whip. "It's a great dessert and only 100 calories," Hassan says.

Tea is calorie-free, has less caffeine than coffee, and is a great source of antioxidants. However, tea won't do much to help weight loss, Hassan tells WebMD. "Sip tea to get full, but I would never tell someone it would boost metabolism."

The bottom line for weight loss, follow a reduced-calorie, healthy eating plan, get regular exercise, and do weight training to increase lean body mass and speed up metabolism, she says.
