Hello again, little about myself, had UC in childhood, and was operated with 2 stages surgery and currently doing fine with pouch, 18 years of age.

So I started weight lifting & strength training in local gym around 3 months ago now, while I did see great results in amount of weight I can now lift as compared to when I started, there is little to no gain in muscle mass whatsoever, obviously nutrition to blame.

I'm one of those teens that think they eat a hell lot, but barely make up 2k callories, oh I'm 5'10 and 110 pounds so meh... I tried gulping down eggs but after 2 eggs the 3rd one just won't go down (I didn't like eggs much since childhood). And while I do try to increase my food intake little, its no where near the amount I need for caloric surplus.

Then few weeks ago I came across this GOMAD diet (gallon of milk a day), and since I have been good with milk from childhood and drink atleast 1 liter of milk a day without feeling vomiting sensation like with eggs or high amount of solid foods, I decided to give it a shot.

So I've been drinking around 2.5 Liters of milk a day now from some 2 weeks (gallon is 3.7 liters but..I think that too much to jump on straight), and here's what I noticed:

1.Bit more gas output while passing stools (manageable)

2.Increase in frequency of visits from 2-3 per day to atleast 4-5 per day.

3.Less formed stools than my 'usual' (by that I mean, they're lick thick liquid, not watery but not hard rock)

4.Increase in the output per visit to the toilet.

5.Lighter shadow of yellow stool than usual

No serious symptoms here I know, the output can be compared to a day when I just sit on the couch and eat all day without any physical exercise, because these past 3 months I was used to much less output & more formed stools.

So basically its just one thing that troubles me here:

Am I actually digesting all those extra callories, fat, protein and what not from milk or are my intestines just flushing out anything above than maintenance callories?

And that might be a stupid question for many of you I know, I also know that removal of the colon does the hinder the ability of small intestines to absorb nutrition, but you know, unless I get the facts straight and out of my mind that these little changes are fine and I am actually absorbing all those kcals, it's really hard to gump down 2.5-3 liters of milk everyday, suspecting that you will only flush it out.
