De-fatting the chew

Keeping my weight at (what I see as) a healthy state has been hard for me. Not crazy hard, but I keep finding I lose weight and then it comes back as my life gets in the way. When I was less not young I never had an issue, but that could have simply been 'cos I was poor.... Once I got a job I found people where saying stuff like "you're filling out" and I since was so in my headspace that I couldn't get fat it took me months to realise that fact was no longer true. By then I was busy in the Navy and had a wife and child so my routine was such that major changes were hard. I got back into weights at around about this time however, and I've always had an ever increasing "gym" since. When in around 2001 I had to go to the USA for a Radar course it occurred to me I had control over my time and diet more, so I got into swimming and weights and I did succeed in regaining some of my teenage muscle gains. Not really much fat was lost though looking at the photos of around that time. In any case, this was a brief time and thus I kept gaining weight over time and it wasn't until about 2009 when I at last came to a conclusion; weight training alone will not keep my weight at a healthy level.
