Query: do it yourself you lazy thing

once again, these fad books suckering people in. and people saying they've lost 5 pounds on this programme? big deal. that's all water or bad scales anyway. i lost 50 odd pounds a while ago and you know how, blood, sweat and tears boys, that's the only way. stop stuffing your chops with fatty fast foods and get out and jog and weight lift your way to health. get up 3 times a week in the mornings and do 16 minutes of hard cardio and do weights 3 times a week at night.
