Calories are the fuel that make you go. Without calories, your body would cease to function. Every action of the body, from cell function to your heart beat is dependent upon calories. The notion that calories are bad is a fabrication. It is only when excessive amounts of calories are consumed that they become a burden on the body.
If you fail to eat enough calories, your body will begin to shut down many of its functions in order to operate with less calories. Also, the nutrient protein, which is used to build and replace muscle mass and other tissues, will be broken down for use as energy instead. This can lead to long-term health problems. If the shortage is too significant for too long, the body will be unable to compensate, and even younger individuals can suffer from starvation in these instances. This is why many anorexic individuals, even teenagers and young adults, can develop fatal heart problems.
So your body needs calories to function, but too many calories will make you gain weight and too few calories will cause your body to reduce function in order to compensate. So how do you lose weight?
Obviously, you must eat less calories than you burn in order to lose weight. You cannot cut calories significantly without your body simply compensating by shutting down systems. Youll need to find a way to burn more calories without making too significant of a cut in calorie consumption in order to create an ideal weight loss situation.
You can see the importance of physical activity when you calculate your bodys daily calorie metabolism. For a rough calculation of this, a sedentary individual can figure out how many calories hes burning each day by multiplying his weight in pounds by 13 calories. Someone who regularly does some exercise can use a calorie multiplier of 14. Someone who does vigorous exercise or combines vigorous exercise with strength training can use a calorie multiplier of 15.
Now, if you want to guess how many calories you must eat to keep your metabolism functioning well and continuously lose weight without changing your activity level, simply multiply the result you received from the last step by 0.8.
If getting to this target calorie level will leave you hungry, you need to consider what types of foods youre eating. Eating more whole grains, fruits, and vegetables and less refined and fatty foods will allow you to eat more bulk while cutting a significant amount of calories from your diet. So you need not go on a food restriction to obtain this. If you need something with some fat to make you feel full, walnuts, avocados, and olive oil are among the best choices you can make.
