I checked the ketostrip last night and it said I was in mild ketosis. Today I got up and did low intensity cardio for 45 min on an empty stomach. For lunch I had 16 oz of crystal light, salami, genoa, provalone cheese, 2 suger free jello, and a salad. For a mid afternoon snack I had some cheddar cheese and mustard. Then for dinner I had 2 turkey burgers, a salad, and a large glass of crystal light. I just checked my levels with the keto strips and it came out negative. What's going on????
