I'm no guru, but a few ideas that have worked OK for me. As you'll see nothing's too radical as I love my food and booze too much and life's too short: "a day without wine is like a day without sunshine"
1) Wanna take 30% of the calories out of your food? Eat a third less. Sounds simple-dumb I know, but as someone said above, you need a lot less then you actually eat. Not only have portion sizes grown over the years, what's in it has gone batshit as well. Your stomach will shrink and you wont feel like eating as much either
Also, relying on just exercise is a problem. What happens when you're too busy, injured, a bit crook, the weather goes shitty or you get lazy? Portion control can work any time.
2) Don't bring the serving bowl of whatever it is to the table - this is where 2nds and 3rds happens. Same goes for leaving the bottle of wine off the table as well. Also, get a vacuum cork for the bottle, which takes away the "it'll just go off" excuse (sorry Lindo)
3) Don't eat deserts, EVER. You're full anyway, and just how revolutionary can that cheescake be? At a restaurant have a coffee instead. If you're gonna give in, don't eat all of it.
4) What do you have for lunch? A sandwich and some chips? Chips are evil and over a week, a pack a day will add up to close to HALF A DAY'S CALORIES. Same goes for a chocolate bar a day. Ditch it.
As for the sandwich, try ditching it for a salad in summer or a soup in winter, as bread is evil as well.
Also, full fat soft drinks are satan's spawn. They use HFCS (a super sugar made from corn starch) that goes straight to fat and has proven links to obesity, go diet if you need fizz.
5) How far do you live from work? Within 10-15k? Shame on you if you're driving every day. Get cycling, running or walking to work, which means you get your exercise in the time it would have taken to commute, saved gas money and made gym users look stupid as it's FREE. This will also make Cutter happy.
6) Cut back on the booze - wine is better than beer, but don't stop altogether or you'll end up like Scarfy
