The first thing I would suggest is that you choose a low carb plan that you think would suit you and buy the book and follow what it says.
Atkins starts at 20 gm per day for 2 weeks than increases by 5 gm daily per week.
Protein Power Plan has Phase 1 at 35 gm or Phase 2 at 55 gm daily.
I think also that you should start WITHOUT those supposedly LC snack foods. Eat REAL food.
It's not so much how many carbs as what KIND of carbs. It's better to eat 30 gm of cauliflower, broccoli & lettuce (and that's a LOT of food) than it is to eat 30 gm of flour & sugar.
Many bars & snacks may be
labelled Low carb but only if you compare them to high carb processed foods. Some of those 'bars' have 50 gm of carbs. Which is better than 300 gm of sugar but not really low carb.
Each person needs to experiment and find how many of these good carbs they can eat and still lose weight. So really, read one of the books. If you look to the right of your original post, you'll see a heading:

But eat REAL food: meat, fish, eggs, cheese, cream, butter, olive oil, salad, LC veggies. Don't use ANY processed foods or mixes or convenience foods. And avoid LOW FAT or LITE foods - they are full of sugar.
