I apologise that I got him mixed up with being obese .
Give us some stats about your dad ?
(usual : height,weight,bf% ...etc)
And what his training regime is like
From what I gather he eats fairly 'average' and does light walking and jogs for a hour ?
Clen isnt a miracle pill
Why is all this relevant ? .... Because in order to advise someone , we need information .
Its all well and good saying , yea taper up + 20mg every 2/3 days till he hits 140 . But whats the point if diet isnt in check , and exercise is also average .
