Stuffing yourself does no good if you can't actually digest it all, so we'll give you the same tips we give everyone else.
1. The people saying "drink cooking oil/heavy cream" are explicitly the people you don't listen to. Fats like these *will* need to be incorporated, but without any carbs to bind to they just pass through with little affect other than upset stomach. Use these items to augment things you eat, do not just drink them.
2. Chew your food more. Easier to digest this way.
C. Take good care of your gut fauna! You can't get a higher digestive throughput without them. Yoghurt, specifically Kefir, is really good for getting a healthy gut fauna.
$. This one will sound counterintuitive, but quitting alcohol helps a ton! Why? Because alcohol can kill bacteria, and is an expense that can be spent on more food. Also, quitting alcohol lowers the overall sugars in your diet and can help stave off diabetes for longer. Quitting drinking is a hard sell, we know, but it does effect your gains. A lot of people will say alcohol helped them gain, and it does initially, but it plateaus you quickly.
