It’s not actually that hard to imagine. Have you been on a diet? Have you ever lost weight? If so, the chances are you put that weight right back on again. I’ve done it. Oprah’s done it. Sam Smith have done it. My cat did it (RIP, my boy).
The truth is that the diet isn’t the hard part. It’s what comes after that’s hard: lasting change in an environment set up for us to fail.
