It's been two weeks since the 20 g netcarbohydrate experiment started, and I'm down 10 pounds with no significant hunger, fatigue or energy loss. Apart from the metallic taste in my mouth (sign of ketosis), I feel great, and have been continuing to do all my activities and work-outs. Apart from the tedium of measuring out cups of lettuce, the experiment has been remarkably easy. I think I screwed up the first week by eating too much protein and too little fat, but, since I cut down the protein and added in things like mayonnaise, avocados, cream, cream cheese, and flax seed, I've been pretty consistently in ketosis. My plan is to carry on for one more week and then start gradually increasing my carbohydrate intake until I reach my individual tolerance level.
Our weekend paddling Pittwater provided a stark contrast between the Fat Adapted Cruisers (FAC's) and the Carbohydrate Crashing Junkies (CCJ's). The CCJ's are overweight and overfat, need to eat every two hours (high carbohydrate foods, of course), and seem to have barely enough energy to get through the day, while the FAC's cruise along eating just three times a day and have plenty of energy to run laps (paddle laps) around the CCJ's. I probably ate a quarter of the calories of the CCJ's yet expended four times the energy and am about four times as lean. A good rule of fours.
