I have done a quasi-low carb diet to great effect. I replaced my normal processed carbs almost entirely with whole grains. Limit overall carb intake, and stick with a diet high in healthy protein and health oils (olive, flax, etc). This means many days I get less than 70g of carbs. It can be hard to stick to, but it is easier for me than full calorie deficit diets because I don't eat squat from fruits or veggies 😕.
I think low/lower carb gets a bad name form the people running around telling you to eat bacon fried in butter all day and you will be perfectly health as long as you don't eat your bread.
That said, there are nothing wrong with some carbs, but getting away from the damn processed carbs is a big step. Not many people realized just how many calories they take in each day in process carbs or specially how many grams of sugar are floating around every way. The easier reason a low carb diet usually works off the bat is due to the fact that as long as you aren't stuffing bacon in your mouth and eating good lean protein (chicken, turkey, lean beef, soy?), you are simply creating a calorie deficit that same you would on a low fat diet.
Overall, remember that diets are temporary. A life style change is what you have to look for 🙂 Get it into a habit and don't fall off the wagon (or at least if you do, just back on fast).
