Doing the Math
A calorie unit is the amount of energy it takes to raise the temperature of 1 gram of water by 1 degree Celsius. In nutrition, the calorie most often talked about is the kilocalorie. Calories make your body move and run and do the things you do every day.
The calories you eat minus the calories you burn result in weight gain. If you eat more calories than you expend by work, exercise and daily activities, you will gain weight. Extra calories are stored in fat cells and make weight gain inevitable.
Diet and Exercise
To lose one pound, you need to expend approximately 3,500 calories. You can do this by reducing your calorie intake by 100 calories for 35 days or any other way in which the math works out. If you don't want to eat less, you can concentrate on burning more calories a day. For example, one hour of aerobic exercise burns around 350 calories, while one hour of bicycling burns around 230.
Ironically, constant dieting has been proven to increase weight gain over time. If you are always on and off crash diets, your body will become unstable, causing your fat cells to hold on to as much weight as possible. Instead of dieting, one should concentrate on changing their habits to eat more healthy foods, nutritional vegetables and less fried foods and empty calories.
In addition to changing eating habits, drinking eight 8oz glasses of water each day can help with weight loss because it keeps your body hydrated and healthy. Moderate exercise should also be a part of your lifestyle if you intend on staying healthy and losing weight.
