What do muscles use for energy during exercise?

Most activities use a combination of fat and carbohydrate as energy sources. How hard and how long you work out, your level of fitness and your diet will affect the type of fuel your body uses.

For short-term, high-intensity activities like sprinting, athletes rely mostly on carbohydrate for energy. During low-intensity exercises like walking, the body uses more fat for energy.

What kind of exercise is best for weight loss?

The best activities are those you enjoy! Regular physical activity is a key component to losing weight, and keeping it off. That’s because physical activity burns calories and helps build and preserve lean muscle. Any kind of physical activity burns calories. However, by choosing activities you enjoy, you’ll be more likely to stick with them for a lifetime.

Does a slow metabolism prevent weight loss?

Researchers call the amount of calories that one burns doing nothing “resting metabolism” or “Basal Metabolic Rate” (BMR). It is true that BMR can be important in helping to figure out how many calories a person needs every day, but there’s never been solid research showing that people with “slow metabolism” gain weight any faster than others. In fact, as people gain weight their metabolism actually speeds up.

The key to weight loss is to eat fewer calories and burn more. Choose great tasting food that’s lower in calories, be careful with portion size and spend more time exercising.

How/why do dairy foods help you lose more weight and burn more fat?

The mix of nutrients found in dairy foods, especially calcium, may be responsible for helping the body break down and burn fat. Studies have reported that dairy foods exert a significantly greater effect on body weight and fat loss than calcium supplements. While more research is needed to fully understand the dairy and weight loss connection, the unique nutrient package in dairy may be a key contributor to dairy's superior effect. In particular, the distinctive proteins in dairy may explain the greater weight and fat loss when dairy is included in a reduced-calorie diet.

Do dairy products make you gain weight or help you lose weight?

Dairy products are pretty good for you, but like any food they have calories. The main issue is that many dairy products have a fair amount of fat. Choose non-fat or 1% milk if you drink milk. Most of recipes that call for milk work fine with either 1% or 2% milk. There are many excellent low-fat cheeses on the market as well.

I use non-fat yogurt for recipes as well as eating and there is excellent evidence that yogurt is very good for you. There are often a lot of added calories in flavored yogurt, so check the label carefully.

Dairy products have lots of good quality protein as well as calcium. Most have been fortified with Vitamin D to help your body absorb the calcium. The low fat dairy products have essentially the same amounts of protein, vitamins, carbohydrates and calcium as the high fat choices.

What does the science say about dairy's role in weight loss?

Dairy foods have a positive effect on weight loss. In fact, research shows including 3 daily servings of milk, cheese or yogurt as part of a reduced-calorie weight loss plan can help people lose more weight by burning more fat than just by cutting calories alone.

A recent study published in Obesity Research showed that people on a reduced-calorie diet who consumed 3 servings of milk, cheese or yogurt each day lost significantly more weight and more body fat than those who just cut calories while consuming little or no dairy.

Are the kinds of foods that you eat more important than the amount you eat?

People will go out of their way to eliminate carbohydrates or fats completely from their diet. Most of the time they end up eating the same number of calories in other type of foods.Calories are calories whether they come from fat or carbs. If you eat too many calories for the amount that you are going to burn, you will gain weight. It is the amount of food that you eat that is important.
