hollipop- I am not suggesting that you have to 'do' atkins...but their website is full of good information regarding low carb...and it's free. (atkins.com) They have some do's and don'ts, and some low carb food lists on both the phase I and II (induction and ongoing weightloss phases). Reviewing these suggestions might be very helpful to you.
In general - lots of veggies are allowed and encouraged. (with very few exceptions, like white potatoes and corn - due to their high carb/natural conversion to sugar content).
Some fruits - with varying serving sizes - with some exceptions.
In a very broad sense - when you read about 'eating low carb' - they are generally referring to eliminating processed foods, and sugars. Bread, pasta, desserts, candy, pastries, crackers, etc... read the labels!!! Better yet...eat things that don't have labels!!!
It shouldn't be too hard to get under 50g's / carbs per day and no more than 1600 calories - just by eating lean protein, healthy fats and great healthy carbs!!! (just get rid of the other stuff in your eating habits - and make your very most favored items become a rare treat instead of the norm.)
Live, Love, Laugh ...make each day memorable and enjoy the journey.
