At first, I didn't look at the picture, and the 446lbs didn't really sink in. When I saw the 23lbs lose in 3 weeks, I thought 'not too bad, actually'. But then I started to do the math. Around 5% change in body mass change in 3 weeks is nothing special. For a person-sized-person, that's less than 10lbs. I'm pretty sure I've taken shits that drop my weight by 10%. A healthy weight change is between 5 and 10% per week.
