Full disclosure: I use a weigh scale everyday, a sleep app, journal, a philosophy, a blog,
I enjoyed the reference in the vid below about carbon app, data driven, nuanced driven, hard work, do your best, do no harm and clear concise science.
Goals: intermittent fast or no supper to sleep better while maintaining keto, no sugar, low carb, better fiber, better exercise in the morning, maintain diversity in my daily content of consumable food for breakfast, lunch (and occasional suppers to maintain weight goal)
