I've always been a big fella, even when I was playing sport and relatively fit I still topped out at over 130kgs (I stand about 6'7"). Due to a back condition I stopped playing competitive sport a few years back, and combined with poor dietary habits and doing shift work my weight ballooned.
Last September after a brief trip to Sydney my wife and I made a conscious decision to be healthier. At the time I weighed over 156 kgs and felt like rubbish, so it was time for a change.
Since then I've managed to drop around 15kgs, and I'm wearing the same size pants as I did in my 20s. Apart from swimming more, I haven't done a huge amount of extra excercise. The answer for us was smaller portion sizes, and making healthier choices when choosing meals/ingredients.
A few weeks back I switched to a low carb diet and it's working well. I've dropped about 5kgs and I still get to eat lots of yummy stuff. I feel a lot fuller and find I'm less hungry than before. I haven't missed bread or pasta, which is weird cos I love both. The positive thing is that it seems maintainable for me so I should be able to stick with it.
The plan is to lose another 10kgs at minimum before our holiday in October. We're off to the States (if it hasn't been blown to bits by Russia and/or NK first) so I need to get under 300 lbs as that is the weight limit for some stuff I'd like to do. I'm currently at approx 310, so I should get there pretty easily.
It feels good. My wife has also lost about 10-15 kgs so between us we're feeling pretty chuffed!
