Thermodynamic laws aren't very useful when talking about weight loss and metabolism. Firstly, the human body is not an isolated system (2nd law).
Also a calorie is not a calorie. One small example, different calories have different thermic effects. I've read estimations that from protein you lose 30% of the calories from the thermic effect, and with carbs you'll lose 15%. Therefore reducing carbs and upping protein will assist with weight loss further. Calories in and out will probably have you losing weight, but it's an over-simplistic view.
