Weight Changes

The nature of weight loss changes over the first 3 ½ weeks of improving your diet. You will increasingly lose more fat and less water during this time. The human body is made up of 70% water. Fluid retention may occur for a variety of reasons (see Reasons Why the Scale Lies on my site), including, hormonal changes, medications, and a high consumption of carbohydrates. These numbers are from Victor Katch PhD research as a kinesiologist at U of M. He is also the author of text books I used while earning my Masters.


Stage One: (first 3 days)
70% water, 5% protein, 25% fat

Stage Two (days 11-13)
19% water, 12% protein, 69% fat

Stage Three (days 21-24)
15% protein, 85% fat

Stage Four (after 24 days)
Stabilizes at 25% protein, 75% fat

This is why weight training is so important. We do NOT want to lose protein (ie muscle mass)

When someone is crash dieting, more than 25% loss is from protein so less will be from fat. See Maintaining Metabolism while Losing Weight on my site.
