Now, at the end of 2021, I have maintained that weight (while also putting on a decent amount of muscle), and haven't left the 170s range for nearly a year. 

Dr. Berg, this is a long overdue thank you that I have been meaning to send you for quite a while.

When I first started corresponding with you a few years ago, I had hit a personal state of unhappiness about my weight and general fitness. 

To give you a bit more context, all of my life through my teens and 20s, I had always been active and stayed in decent shape (without paying too much attention to my diet).  I am 5'10", and though my weight fluctuated at various times, I never strayed outside of the 170s to 180s lbs range for many many years.

Shortly before I turned 30, I was working a job where I was mainly sitting at a desk all day, and also where I was consuming much more carbs and sugars than I had had previously.  By the time you and I were in touch in 2018, I was now in my early 30s and weighed nearly 230 lbs (to be totally honest, I stopped weighing myself after I hit 228 lbs because I couldn't confront how far gone I was, so I don't actually know what my highest peak was).

It took me another year before I actually got serious about doing Keto and Intermittent fasting (mid-2019).  So by 2020, after disciplining myself on my diet and exercise (based on all of your advice and the information you put out), I was back down to nearly 170 lbs.  Now, at the end of 2021, I have maintained that weight (while also putting on a decent amount of muscle), and haven't left the 170s range for nearly a year.  People who knew me in my "big boy days" and who haven't seen me for a while, often don't recognize at first that I'm the same person when they see me now.

So even though in my estimation, I most definitely still have quite a journey left to attain my ideal state of health and physique, I just wanted to let you know about the amazing results thus far, and thank you for everything you have done to assist with this.  My wife and I still refer to your YouTube content on a weekly basis to answer questions we have or get new tips on things we can do to improve our health.  So thank you thank you thank you once again.

Best,

Stephen
