At the end of the day, it's calories in < calories out.

I wouldn't recommened a high carb diet for a few reasons:

1. Carbs have a lower thermic effect than protein. IOW, it takes less calories to break down carbs for absorbtion and metabolizing.
2. Cals/g of carbs = cals/g protein, but see #1 above.
3. Carbs affect insulin response quite readily, regardless of whether they are complex or simple. The only carbs that do not affect insulin levels is fiber and I think most sugar alcohols. Insulin is responsible for moving glycogen/glucose to muscle and other active tissue, but also into adipose. I high carb diet means a lot of insulin in the blood stream.
4. Fat is 9cals/g, so if you're combining a higher fat intake with a higher carb intake, you have a lot of insulin in your blood, along with a lot of calories that the insulin wants to move to muscle and adipose.
