There was a time when a 300-pound player would have been considered too tubby for football.

In today's game though, anything much less makes an aspiring pro look too runty for the NFL.

Some players, especially offensive linemen and defensive tackles, gorge on tubs of ice cream, entire pizzas, burritos and burgers to keep their playing weights up.

The added pounds come with added health risks. One 2005 survey found that linemen were more than twice as likely to die before age 50 than players in other positions.

After retiring from football, some players have trouble curbing their eating habits and their weight balloons.

Some find strategies to change their habits and shed major weight though - in some cases within months, in others over decades.

Here are 15 NFL players who have lost major weight since retirement, and the surprising array of strategies they used to shed the pounds.
