I've just completed a year on MFP and am pretty chuffed at what I've achieved;
From almost 19 stone down to just over 13 stone (6'1" male)
Waist from 48" down to 34"
Running 5k every other day
Resting HR down to 38 bpm
To be honest (and I know some people will not want to hear this) it's been fairly easy to do and here's what worked for me;
a) Data - I'm an engineer and I love data, being able to draw graphs of calories, weight, distances run, waist, hips etc has been a big help in making me stick to this. Oh and don't lie on your tracking as it helps no one.
b) Fridays - Me and the wife have a massive pizza and 2 or 3 pints on a Friday, as long as the weeks calorie total is under the weekly goal it doesn't seem to impact the weight loss and after a week at work you need something to look forward to
c) lunch - spend 5 minutes in the morning making a packed lunch it stops any temptation to wander
d) Exercise - I neither love or hate running and lifting, most people seem to love one or another and get a lot from them. To me they're a means to an end and need to be done - it's not that i dread doing it more like i just switch off, get it done then move on. I'm a fairly stoical brit so maybe that's just easier for us.
e) Maintaining - very tricky, I set a target of half a stone variation around 13 stone but my god it oscillates around a lot. I've been maintaining since feb this year and its harder than losing
f) Pot belly - at some point you have to say sod it it's never going away and as point d) shows I will never care enough to get into serious 5x5 or a bulk/cut cycle so it will stay. I can live with it and am much happier with my health/appearance
I've got some pics but I don't think anyone wants to see a pale, miserable Welshman.
