Feel sorry for the poor people they did donate ! Let's face it must be a lot of them. Does anyone know anyone who did ? Probably saw themselves as his friends as he did have a little bit of a cult like following if I recall correctly.
I get that it's much more easier to gain than lose weight (I've never managed the later, not a large amount anyway) but from what I recal he was on runs everyday and always at the gym. How can you be the kind of person who runs / gyms daily sometimes two times a day and then just stops ?! Like lost weight skin off stop.
I'd say he was your classic restrict/binge person. He lost the weight so quickly, I don't remember his food portions looking massive so he no doubt was on bare minimum when for his size he could still have eaten a fair amount and still lost weight. Then he exercised obsessively, I think of him every time I see a stairmaster
The first thing he did when he hit target was have a Dominos pizza as he hadnt had anything like that since he started losing weight! I suspect it went downhill from then on.
There's a girl I follow called Caggietskescontrol_sw who lost a large amount, I think 10 stones in a year and did something similar. She hit target just before Christmas then disappeared, reappearing a month or so later having put on at least a couple of stones. Not that this girl is anything like Towers otherwise, she seems lovely but I think it's quite common to rebound after restricting for so long.
