Hi Jaji.
Have you read Fergus's 'Newbie's guide' at the top of the Low-carb forum index? That will help you understand the process better and will help you get started.
I think that the biggest hurdle a lot of people have to overcome is understanding which foods are carbohydrate, which are protein and and which are fat. That may sound like pretty basic stuff, but you would be amazed how many people don't know.
You don't need 'shakes and stuff', Lighter Life or Slim Fast. They may help weight loss, but people who use them rarely keep the weight off because they then go back to eating the way they were before and put it all back on. You just need to eat plenty of really healthy food and leave the 'rubbish' - the processed 'open a packet and stuff it in' stuff well alone. You're not needing to count calories here, because once your body is in fat-burning mode rather than carb-burning you will naturally lose weight despite eating plenty of food. It's not so much about how much you eat but about the type of food you eat.
Can you cook? Make salads? Learning to eat proper foods - real foods, rather than the 'dead' stodge that passes for food these days is what makes the difference. If you radically lower the carbs, you will probably need to up the fats, but fat does not make you fat unless it is eaten with lots of carbs. Fats help you to keep fuller for longer so you don't have such an urge to snack between meals and that will make a difference too.
Most of us in here have started from a similar place to you and many of us have lost weight too - just have a read through the success stories! More importantly, we have been able to get our sugars under control and many have also found that other health problems have also either gone or have considerably improved.
It may be difficult to start with because it means turning over 'deeply entrenched' ideas and beliefs and adopting a whole new concept in eating, but once you become familiar with it it becomes 'second nature'.
You've come to the right place for help and encouragement. I hope you can manage to make it work for you.
