I live alone, work 55-65 hours a week, 80 minutes total commute time, so eating real food and getting the exercise I want in the time remaining is challenging. Like you I eat the same stuff. Chris Masterjohn calls it the robot diet.
Saturday is shopping day, Cosco, Walmart, vegetable market (and is the day I eat nothing). I prep 5 lunches, ready to grab and go in the morning, HB eggs, nuts, cheese, jerky sausage. On sunday I make a week supply of olive oil and vinegar dressing plus seasonings, enough for 6 of my very large dinner salads. I cut vegetables for the Sunday and monday salads. On Teusdays and Thursdays I cut veggies for two salads. Final salad prep is adding meat, avecado, tomato, then exercise, then add dressing and eat dinner. I skip breakfast except for Sunday morning (bacon and eggs) after the Saturday no eating day. I eat meals only, no snacks ever. If I want a treat it’s desert. I don’t think about time restricted eating, I think about frequency restricted. May be I used to eat 3 meals plus 2 snacks, 35 times a week. Now I eat 12 times a week. Those 12 meals are large, filling, satisfying. Since they are low carb I don’t need a nap after the meal.
(For the fiirst time since starting keto I actually cooked something this morning, easy keto bread, and ate it with cream cheese. It worked. Texture is fine but it needs some sort of added flavoring. I’m ready to do more cooking when there is time to experiment.)
I track with Cronometer and pay the $35 annual subscription so I can save recipes, which makes it easy to verify nutrient content. Tracking is time consuming but has been worth the time so far.
