Firstly - it works! You may feel bloody awful for a few days (headaches, shakes etc), but stick with it, you will feel so much better afterwards. Most people on a "normal" western diet are eating nothing much apart from sugar! By sugar I mean table sugar, other sugars and syrups, breads, cereals, rice, potatoes... all sugar, all mess up the metabolism when eaten in the quantities we consider "normal" in the modern diet.
As a long term low carber ( about 7 years now, apart from a bit of a falling off the wagon for a few months after the birth of DS4), my tips would be, do some reading into WHY a carb heavy diet is damaging, because weight loss is a side effect of getting blood sugar levels under control (which reduces hunger and binge eating), and understanding how/why can help you make better food choices.
Example, if I have an isolated high carb day, it gives me carb cravings for a couple of days, so I try to go for low carb treat foods even when I am having an "off day". Following are two links, with all the info, free! Also there are lots of very experienced low-carbers on MN.

When I first started, it was all about weight loss, but 6 stones later, it's the long term health implications which interest me now. For the first 5 years, I restricted carbs, but did not cut out any carb group altogether... but now I have cut out gluten/wheat and feel much better for it - in fact I eat no grains at all apart from some occasional white rice.
So, at the moment, my easy to follow rules would be, don't eat anything with more than 5g carb per 100g. No "low fat" products - eat full fat versions but less often! You will get more nutrition from eating leafy veg, carrots, onions, Cauliflower than from the bread/rice/pasta you would have filled your plate with instead! Cook from scratch as much as possible, and buy a slow cooker - great for low carb family meals. The family eat the same as me - but often with a little white rice or a few baby potatoes on the side.
