Now here’s kicker. Since my body is not going to want to keep using up its fat stores, it is going to adapt by lowering how many calories my body needs per day to keep itself running (RMR). One of main ways it accomplishes this is by eating away at it’s own muscle. Instead of requiring 2500 calories a day to keep my body running, my body will eventually adapt over a period of time and only require 1000 calories to keep running. Back when our ancestors lived they needed this calorie adaptation to survive when food was short and they were starving. The trouble is, body cannot tell difference between starvation and dieting. Now that my body’s RMR has adjusted to new number of calories that I’m are eating, it no longer needs to use its emergency fat stores to keep itself alive. This is when your fat loss stops from a diet. In addition to this, if I decide that I want to go off of my 1000 calories a day diet and begin to eat 2500 calories a day again then there is a calorie surplus. The body does not need these extra calories so it will store them as fat. The exception to storing them as fat is when body needs to build muscle because it has been exposed to some type of exercise or weight lifting, and even then all of calories are not used for muscle growth.
Now that I have changed my RMR to 1000 calories per day, I have really wrecked my metabolism and it’s going to be harder to get to my goal of actually losing fat. That is, unless of course If I want to stay on my diet forever.
So what is best way to lose fat without messing up my metabolism (RMR)?
A calorie deficit is required to lose weight, but eating less is not only way to create a calorie deficit. Another safer way is to exercise. More detail can be found on this in Tom Venuto’s book “Burn Fat, Feed Muscle”, which is located at http://www.weight-loss-resources.com.
