I had a lap distal RNY 20 months ago. At six months out, due to strictures and food intolerance, I was just starting to consume foods that weren't pureed or soft. My experience was atypical; most people can tolerate solid food by month two or three.
Regardless, after WLS, you need to eat protein forward. That means your measured protein source is consumed first and then if space remains in your pouch, you can eat veggies or fruit. Carbs should always be limited.
By six months out, most foods can be consumed in moderation. Some foods you may never be able to eat again due to reactive hypoglycemia, dumping, or food intolerance. The idea that you'll "never be able to enjoy (...) again," is usually false. I, for example, have no problem with sugar (dang), but can't have heavy starches like rice or pasta, as they cause me great discomfort and sickness.
I think I was eating 1/2 cup amounts at six months and at a year, I could consume about a cup of food at a time (depending upon the food). For example, I can eat a lot of lettuce, but beef only about 4 ounces at once.
I'm not sure if that was the type of information you were looking for. I no longer recall my exact menu at six months, but it probably wouldn't help you anyway, as most people recover quicker than I did.
