Fat Joe Speaks On His Massive Weight Loss

It scares me when people lose a lot of weight in a short time. When I was a kid, three obese women lived down the street, a mother and her two daughters (19 and 21). They were Samoan women. The youngest went on a crash diet. She went from about 300 to about 100 pounds in less than a year. She died of a heart attack, when she was 20 years old, soon after she had achieved her weight goal. Her doctor said she had stressed her body too much with the rapid weight loss.

Wiki has this on Fat Joe's weight loss
So losing just over 1kg a week while eating a sensible lowish carb diet and regular exercise seems a good idea to me. I don't think he's putting himself at increased risk. I think remaining overweight would be a greater risk.

He was motivated. For me, being called 'Fat Joe' would be enough motivation. Hopefully, they can just call him Joe, now.

Here's a Swedish Guy Freddie at “Sweden’s fattest blog” doing much the same.
