I'll keep an eye out for that. I am trying to put on weight so I do end up eating a lot of fat. Maybe I switch them out for more carbs.

Yes, I was going to say generally milk labeled as lactose-free really shouldn’t have any noticeable amounts of lactose in it, so if someone’s still having trouble then lactose might not be the cause. I have heard relatively recently about something called A2 milk that doesn’t have an A1 protein which is found primarily in cow’s milk but not in as many other mammalian milk, including not in human milk. It looks like it might help some people for whom lactose-free cow’s milk still doesn’t solve digestion issues, but the evidence might not be very conclusive. I haven’t tried it myself; lactose-free works for me.

i have ibs so it makes those things more intense for me, i get the same thing with milk, plus i think im mildly lactose intolerant. something like "flavoured" milk doesnt cause a reaction though,

High fat diets can help facilitate LPS (a bad, fat-soluble, inflammatory molecule) from gram negative bacteria in the gut into the bloodstream which can heighten systemic inflammation (endotoxemia). I feel as though that's a common issue these days that not many people may know about.

Look into bile acid malabsorption (BAM). It's surprisingly common. In the U.S. you don't commonly use the SeHCAT machines so they prescribe cholestyramine and see if it helps. Give it a go. Very few side effects and you have a lot to gain if it works. Plus if you take it long term you actually reduce your cholesterol levels.
