So many myths surrounding fat burning, ladies.

Remember, you have dietary fat (ie the fat you eat) and adipose (the fat you store around your middle). We do not use adipose for fuel during exercise.

We are always buring a combination of carb, fat, and protein. While fat is burned in a higher ratio during lower-intensity exercise, you're also burning fewer calories for the duration, so the logic that there is a "fat burning zone" or that you'll melt away your middle by exercising at a lower intensity is a myth. Our bodies are very inefficient using fat or protein as fuel. Carbohydrate/glycogen is the preferred fuel source (and our bodies are very good at utilizing it).

We lose weight/fat by increasing our caloric expenditure (burning more calories through activity) and/or decreasing our caloric intake (eating fewer pints of Ben & Jerry's). It's that simple. It really doesn't matter what intensity exercise you do. Move more and eat less.

If you want to lose fat (or you want your husband to lose fat), you're referring to adipose (the stored fat). The only way to lose that fat (besides liposuction) is to deficit yourself 500-1,000 calories/day. This equals a weight loss of approximately 1-2 pounds a week (3,500 calories = 1 pound). If you deficit yourself more than 1,000 calories/day, you will also lose muscle mass and/or your metabolism will respond by slowing down.

Weight gain was a gradual process -- you don't become overweight overnight. Weight loss is also a gradual process, so be patient.
