Tell RGR hes gonna have to work out 6 days per week. but more importantly, dont eat after 4pm. fasting between 4pm and 9 am works wonders.
also, no alcohol; otherwise the pounds just stay on due to the starch intake and reduction in testosterone that comes from alcohol and nicotine consumption.
in his case, dieting may be all he needs, but to speed it up, working out will be expedient.
this is coming from twenty years of fitness experience. i used to be a heavy drinker and eater, and i did not get really fit until i stopped drinking and started eating better and smaller portions.
best of luck
