I have idiopathic postprandial syndrome / carbohydrate intolerance. If I take too much carb especially simple/ refined carb my body starts to become weak tired and shaking just 2 hours after eating no matter how full I eat and I need to eat until full again then only OK(eating a bit won't help). I'm obese because of this and even was at prediabetes, I can't follow keto too risky for me. I take complex carbs like whole grains it helps I start to become weak 2.5 to 3 hours after eating full. I can only think of 2 whole grain bread egg  canned tuna. I can't afford expensive food. I need something  healthy affordable low carb  for daily. Processed meats too risky for me since I'm obese, have fatty liver and quite high cholesterol. Please help thanks.
