im not trying to be an ass, im just letting you know eating that low is not a good idea |
Why do so many people seem to think that when you're starving most of the weight loss is from muscle? Actually most of the weight loss will be fat. There will be protein loss, and most of the protein loss will be from muscle rather than other sources; but of the weight lost, a far greater proportion will be fom fat than protein. Typical protein loss for someone who had starved for 5 weeks would be about 3kg, and fat loss over the same period would be about 10kg (figures read off a graph showing the effect of starvation on the food stores of the body in "textbook of medical physiology" by Guyton and Hall)
