You'd have to look at the rate of weight loss, actual fat loss, strength levels, and realistically assess if you can get away with less than you're currently doing. For example, if you're doing a ton of cardio, barely eating any carbs, and dropping a steady 3 lbs per week, chances are that you'd end up better (compositionally, not in terms of scale numbers) by pulling back on the cardio sessions, and possibly even working some more carbs in, albeit in small increments at at more useful times of the day. Then of course you'd reassess matters; what's the rate of weight loss now? Is your strength returning? Sleeping better? Mirror based composition? etc..
You have to realize that the body will eventually adapt to anything. How long that takes to happen is a very individual matter. Some people will have issues from the get go, and respond better to varying, or cyclical approaches. That's not saying that others can't set up a dietary/training program, follow it for 2 months without ever making any changes, and reach their goals with seemingly little effort.
It's really when you're dealing with acheiving more drastic levels of low bodyfat while doing everything you can to avoid muscle loss that you find yourself playing games with so many variables. Remember that your body is designed to preserve itself, and storing bodyfat is something it can do quite easily in certasin circumstances.
Similarly carrying around large amounts of muscle mass isn't usually a priority. Hence all the crazy complicated sounding juggling you hear some competitors dealing with. Certainly, for most people, there is no reason to overcomplicate matters if you don't need to.
