My milestones on Keto:
Losing 22 pounds over the last 6 months. Now I'm actually noticing how many pieces of my wardrobe are starting to sag a bit or feel lose in places. Still have another 15-20 pounds to go to get to where I want to but I'm definitely getting there.
Blood work looks really good - only LDL slightly elevated, a couple of tests close to lower limit (iron, calcium - yes, have already begun supplementing). This is the thing I'm the most happy about - a year ago I had a lot of the results (surely 5-6) coming back just over the normal range or in some cases much over (including total cholesterol and triglycerides).
Feeling much more energetic so I'm getting things done both at work and at home.
Clarity of mind: remembering things, being able to focus better. This one I'm looking forward to getting even to a better level (betting on getting those iron levels to the right spot and replacing some screen time with time in nature).
