You're doing fine. I recently blogged on why this is OK; I'll repeat here for you:
Your body has to principal fuel engines, you burns glucose (carbs) the other lipids (fats), and they do not run at the same time. Your body does not tolerate glucose well so it burns it first, if can’t get rid of it all, it converts the remainder to fat, but more importantly it prevents your fat burning engine from turning on until he it is done with the glucose. At under 50 grams of carbs (with moderate protein) you will most certainly turn on your fat burning engine.
Why moderate protein? When you consume too much protein, the excess is turned into glucose just like carbs. You may be under 50 grams but if you eat too much protein you will delay the start up of you fat burning engine.
Your fat burning engine will burn the fat you eat, and the excess fat on your body… when it’s turned on. Once you get pass the carb cravings, your fat engine will communicate with your mind/stomach and actually stop you from eating, and start to burn more of the fat on your body. When at least 50% of your calories are coming from fat in your diet, this happens quickly. Generally within three days of starting a low carb high fat diet, you will seem to lose your appetite; this is because your body is burning your fat for fuel. It doesn’t need you to eat.
There is one other point worth mentioning. Carbs require water, lots of water to process, when you reduce your carbs you also reduce your retention of water, this is part of the reason your weight drops so quickly at first. It is also why it goes up so quickly when you decide to eat more carbs. If you are planning to eat more carbs after you have lost your weight, set your goal at least 3 lbs lower then were you want to be, to allow for the water gain as you add carbs.
That’s about it.
