Cocoa you need to read up more on low carbing, it actually has a proven reverse effect on bad cholesterol, in spite of how it might seem.
Low carbing really really works, (if you stick to it and don't cheat) but in the short term it requires you to eat a lot of fat and protein but very few carbs, then eventually you return to a more balanced system but still picking your carbs wisely and keeping them within limits.
The danger with low carbing (as I have found to my cost many times) is that you can stuff your face full of butter, cream, cheese etc and miraculously lose A LOT of weight pretty quickly, but if you don't stick to it and make sure you remain in a state of ketosis, but keep yo-yoing in and out of ketosis or starting the day on a low carb, high fat diet and ending it on 3 glasses of wine and half a packet of digestive before bed as you fall off the wagon yet again, you are taking on zillions more calories than you might otherwise have done if you just ate 'normally' by eating too many carbs and not actively trying to up your fat levels. Does that make sense?
Giving it a proper go takes a real leap of faith in the first few days when you really do need to eat a lot of fat and protein to get yourself well and truly going, then it becomes much easier after that and you soon find you don't need to eat a huge quantity of anything much, but you can if you want to, so long as it's low in carbs. Unlike a calorie controlled diet where you max out quickly and if you are still hungry then tough luck.
The other danger of low carbing is that when you have lost your weight and are just trying to maintain it, you become accustomed to being able to eat all those previously demonised high fat / low sugar foods like avocados, egg yolks, nuts, lard, butter etc, and you keep doing it even when you aren't actively trying to diet and cut the carbs. Once you know that they aren't the work of the devil and in many cases are actually incredibly good for you, you think 'why not?'
But if you are going to be eating everything in moderation to maintain your weight loss then that's exactly what it has to be - MODERATION! Not wolloping great slabs of butter and cheese on your Ryvitas or your little bit of bread if you are going to allow yourself Ryvitas and bread, because it's too highly calorific overall and if you are not trying to get into ketosis (or have knocked yourself out of it by eating too many ryvitas) then all those calories from fat will now count. So you are back where you started. 
Personally I could never go back to counting calories or doing the everything in moderation way of dieting. I find it easier to just stay away from high sugar or wheat based foods altogether. I can't eat them in moderation, they set off a chain reaction in me of wanting more and more. Even if for example I ate supposedly healthy and satisfying porridge with apple or raisins or banana for breakfast, my sugar cravings will spiked and I want to snack on carbs all day long, then feeling inexplicably tired and lethargic and craving more carbs, even if I know logically I've had enough food.
And I love porridge but I don't want to eat it without some sugar, so even though the porridge is supposedly good for me and will fill me up, the sugar will make me crave more sugar as will the carbs in the porridge.
Proteins and fats satiate your appetite better than low fat or fat free carbs will, but of course fats are very high in calories, so when combined with carbs you are getting the worst of both worlds because every calorie counts. Unless you do LOADS of exercise to burn it off.
For people who are unsure of how low carbing works, in a very simplistic nutshell, it's this:
Eating fats and proteins in pretty large quantities in the absence of very many carbs will mean that the calories DON'T get converted to fat and stored as unused energy (body fat) for another day, they just get partially used and the rest flushed out. In the absence of many carbs in your diet your body will always chose to take your stored body fat and burn it for energy first, rather than use the calories that you've eaten from fat or protein that day.
But as soon as you eat some carbs it will chose to use those first instead because they are quicker and easier to convert to instant energy than either dietary fat and proteins or stored body fat. That's why allowing carbs in your diet in any great quantity (regardless of how apparently healthy their source is - fruit and wholegrains or quinoa for example) will always mean slower weight loss. Because unless you exercise like crazy to burn MORE energy than the energy you just took in from the food you ate, all you are ever doing is topping your body up with a readily available and easily converted source of energy - carbs. So your stored body fat stays exactly where it is.
It's the equivalent of having a full fridge and still going food shopping every three days, shoving more food into the front of the fridge and ignoring what's already in there, using whatever's nearest/freshest at the front then complaining you've got too much unused stuff at the back.
