Thanks for the share, OP!
I've been undergoing my own transformation myself. When my scale hit 294 in November 2016, that was my final straw to get up and do something about my fitness.
As of this minute, I'm down from 294 to 202.
My approach was less scientific than yours, I simply took a "No Days Off" approach to my fitness. For the first 6 months, I did nothing but walk on a treadmill at 3.5 speed with an incline of 10 to 13. Now I've really tried to integrate strength training to ensure I don't sweat away my muscle with the fat. On weekends I do twice a day workouts, and I epsom salt bath those days to recover from muscle soreness.
As far as my food situation, I've drastically changed up my diet. No more sugary juices, sodas, fast food, or hearty meals. Eat lots of half sandwiches, salads, wraps sparkling water (really helps simulate that full feeling), and my singular major meal for the day is usually at 4pm. Whatever that meal is, I strive not to intake more than 2 pounds including my 16 oz. beverage.
Finally, the secret sauce is the accountability thru my WIFI scale. It measures and tracks everything, sending data directly to my phone. Got this midway thru my journey so it doesn't go back to November '16, but it's been my best friend thru this somewhat lonely journey:
I'm 5-10 and my target weight is 165. Hoping to get there by end of year, then transition over into maintenance mode.
