good article, I can (unfortunately) relate.
another aspect of the trap is when you have set backs (stress, life events) or get tired (long days, less sleep, emotional events) typically the first recourse is to stop the hardest parts: physical fitness, e.g., you take a car instead of bike/walk, skip sports, alcohol instead of water.
it's sometimes a vicious circle, you're tired due to overweight, thus eat more to get energy, making you more overweight.
