I think this ice water (or cold beer, as the case may be) story was an urban legend started by ignoring the fact that calories in the United States are in fact kilo-calories. (Check product packing in the UK, for example, and you'll actually see KCal)
The route to sustainable weight loss is simple - but like many things also difficult:
- Eat 400 or so calories less than you RDA in a balanced diet. I would recommend about 1500/day for an adult man. Don't skimp on protein. You can up this once you reach your target weight.
- Eliminate or severely restrict alcohol intake, along with that of any sugary drinks. Consider, one beer or coke per day is 150 calories, which is about 1.5 miles of running to burn off. It's an intake of 54750 calories per yer, meaning you'd have to burn off an extra 15 pounds per year just to break even! Plus, the more you drink, the more likely you are to lose your discipline and eat that late night burrito.
- 30-40 minutes aerobic exercise such as jogging 5-6 days per week
- Modest strength exercises (core strengthers like crunchers or plank exercises and basic weigh-lifting) every other day, expecially if your aerobic exercise is leg-centric. You only need about 20 minutes of this.
That's it. Ramp up a bit more aggressive if you like, but I recommend not going overboard because the whole point is to make a sustainable lifestyle change.
