all41...I've heard from quite a few people that were able to drop numerous pounds simply by quitting drinking, so that in itself is a powerful weight loss plan. However, if you at all have an ascetic streak, I can't recommend intermittent fasting enough. It's popular with the paleo / crossfit crowd (of which I'm neither) and has very strong science behind it. There are many forms. The most popular (and the one I've been doing for 5+ months) is basically an "16:8." It's very simple. You have a 16 hour fasting window (zero, repeat zero, calories), followed by an 8 hour feeding period, during which you consume all your calories for the day. Most people eat their last meal at 2000, and then don't eat again until 1200 the next day. If you mix this with some cardio and HEAVY weight lifting (4-6 reps, 9-11 sets, progressively heavier), you can't help but quickly move to your ideal lean weight. This time last year I was a very soft 164 or so. This morning, I weighed in at a very lean 147 (my daughter says I looked "jacked," which is pretty cool in your mid-40s). This was with pretty lame workouts and eating all sorts of crap -- pizza, McDonald's, icing, ice cream, giant meals, etc... When January rolls around (which is always my "strong" time in the year cycle), I plan on switching over to a more clean diet during my feeding times (i.e. no regular junk food, but I'm still able to eat whatever I want if the occassion arises). I think I've been eating so much high fat food since I started because I was afraid I was going to lose too much weight and be a bean pole. I'm confident now that I won't be, and can still gain muscle over the next few months. Oh, and the whole process has given me way more self-control and swagger.
P.S. It's actually good for Diabetes because it gives you ideal insulin levels. Just a tip, research more online. A good starting point is
www.leangains.com, which explores some of the diet myths that abound (e.g. "You need to eat six small meals a day to keep your metabolism high.").
Good sources for men's self-improvement (and there are many, many out there) = leangain, boldanddetermined.com, The Art of Manliness.com, Rational Male by Rollo Tomassi, bodybuilding.com, and of course marriedmansexlife.com (which completely turned my life around, sexist or not).
