I've been reading the book Mindless Eating: Why We Eat More Than We Think by Dr. Brian Wansick. It's a very interesting book. It ta;ls about how if we just lose 100-200 calories a day we would lose weight. It says take something you eat every day such as a soda with 140 calories. If you divide the number of calories by 10, that is the approximate weight you would lose in a year if you quit eating it. So for 140 calorie soda, that would be 14. For 270 calorie candy bar (a day) you would lose 27 lbs.
It also says that when you can't see how much you eat (like a buffet) you lose track of how much you have eaten. A study they did with two groups eating chicken wings. One group that had their chicken bones removed ate 28 percent more than the second group who had all their bones in front of them.
Another thing is prisoners with a six month sentence gained weight. Was it the food? No. Lack of exercise? No. It was because they wore baggy jump suits that didn't fit them firmly. So if you are wearing lots of sweat pants or stretchy clothes, get rid of them. Your clothes getting snug is your body trying to tell you to pass on that cup cake!
I was riding my bike last night and my bodybugg said I was burning 5 calories a minute. That means that fiber one bar I ate (150 calories) was not going to be “burned off” until I rode for at least 30 minutes. The bad news is when I ate this I wasn't really hungry. If I had hung in there a little longer, the calories I was burning would be making a bigger deficit. So if you are in a hurry to lose weight, you can speed things up by diet. Exercise is good, but in the 2 minutes it takes to eat a fiber one bar, it takes 30 minutes to burn it off.
Be careful, and don't take this too far. If you don't eat enough calories (typically 1200 for ladies, and 1500 for guys – check with your doctor) you can put your body into starvation mode and hurt your metabolism.
