What do you mean by bariatric foods? I just ate regular foods from purées not even shakes or Protein powders. Sure my protein intake was low to begin but it got higher. What is your protein goal? Are you focussing on eating the protein component of your meal first then any vegetables & finally only if you are able & permitted any carbs. At 7 months I would expecting you’re eating about 3 or 4ozs of meat for a meal now. 3ozs chicken breast has 26g protein, 3ozs tilapia has 22g. Depending on your goal that’s a good 1/3 of your goal in one meal.
I supplemented my protein intake with a high protein yoghurt (mine has 20g) or yoghurt drink (blend yoghurt with milk & get 30g) as a meal & then a snack. I still prioritise protein in every meal & snack (except if it’s fruit of course).
