Well, I didn't start a diet. All I did was cut sugar. I did and still do run a couple of miles and lift weights a few times per week, and ate the same meals every day (because I buy in bulk and prepare them ahead of time). I track all my food and water intake and exercise activity with my Fitbit (unintentional plug). It was an environment with tightly controlled variables. Nothing in my routine changed except the subtraction of sugar from the coffee I was drinking.
