there can be much confusion about bodily processes during and after the fasting process.
The body has a wonderful way of preserving its protein on a water-only fast with what has become known as protein-sparing.
Over a 30 day Water Fast a person generally loses a maximum of 1-2 pounds of muscle mass. This conservation of the body's protein is an evolutionary development that exists to protect muscle-tissue and vital organs from damage during periods of insufficient food availability.
As you may already know, the main fuel supply on a water-only fast is ketones: the use of fatty acids as fuel instead of glucose.
When anyone breaks a fast this shift is made back to glucose as the main fuel source, and any further depletion of your protein stores will be reduced and eliminated in a very short time frame.
The body will break down any surplus protein from the diet into organic acid and where this is then converted into glucose which can then be used for obtaining energy. In other words protein conversion into carbohydrates.
Strawberries and salads contain amino-acids that go to make up your own human protein, and where it is a fallacy to think that chicken (for example) or any other meat protein is human protein. Chicken protein is after all chicken protein and NOT human protein.
I wouldn't worry on that score. You will replenish your protein stores in next to no time ( Shelton did admit though there is a greater need for protein post-fast) in the anabolic process, along with the other elements of health such as Vitamins and Minerals and so on. Shelton and others recommended more protein after about one week post fast by consuming more Nuts, Avocados, Legumes, and even those aminos found in fruits.
