Corrective action #1: I began to consume three Brazil nuts at breakfast and three Brazil nuts at bedtime. Too much selenium hurts swimmies, so I kept well within the tolerable upper limit for adults, which is 400 micrograms per day. One ounce of Brazil nuts (approximately 11 nuts) provides 544 micrograms, so 400 micrograms is approximately eight nuts per day (49 micrograms each). I am consuming six to play well within nontoxic ranges. I experimented twice with higher ranges of 810 nuts per day; in both cases, I immediately broke out in the worst acne of my life. Though selenium de ciencies can cause skin problems, it appears that excessive selenium, or at least Brazil nuts, can do the same. Corrective action #2: Second, I am ensuring that I exit ketosis at least once per week by consuming carbohydrates à la the Saturday cheat day on the Slow-Carb Diet. Since I have tested
