Ketostix not showing ketosis
I am 6'3, 265 lb., about 32% body fat, 55 years old.
I have been eating a pretty clean ketogenic diet for the past week. Here's my average daily macronutrients breakdown as calculated on MyPlate:
Calories - 2,000
Protein - 180g (50g from whey isolate, 28g from eggs, 21g from cheese, and the rest from beef, chicken, fish)
Fat - 110g (15g from avocado, 20g from eggs, 27g from cheese, 16g from almonds, and the rest from coconut oil, olive oil, beef, chicken, fish)
Carb - 15g net (mostly from fiber supplement, green foods supplement, almonds, avocado)
I do one hour weightlifting four days a week, and 60-90 minutes of cardio walking the remaining three days.
After a week I tested my urine with a ketostix, and it measured zero ketones.
I am thinking that I should have registered ketones by now.
I drink a 42oz diet coke every day, and another 32oz of crystal light each day. I wonder if the artificial sweeteners may be screwing up my insulin response and keeping me from getting into ketosis.
I'd appreciate any thoughts on what I should be doing differently to get ketosis kicked off.
