Hello!) What about butter? How it can distribute fat? It has got dairy fats and a lot of calories...

Butter should work fine in terms of weight gain and fat distribution. Due to its lack of Milk Fat Globular Membrane(MFGM) though, it'll increase LDL more. As such, I prefer cream over butter in terms of fattening one up but you'll probably be fine TBH. Now that I think of it, the same could be said about cocoa butter too. I wouldn't worry too much about it, it's likely just a transient postprandial effect.

Weight gain is a slow process so 1 to 2 weeks will net you no measurable results.

Harry-Misty:
Hmm, interesting, I'll try to test it for 1-2 weeks, and for weight gain, how much butter do I need to eat for gaining weight?

becomingoverweight:
The rate of fat gain is (C-TDEE)/7716 kg/day where C is the amount of calories you eat in a day and TDEE is how many calories you need to maintain your weight. So you need to eat C=7716R+TDEE calories to gain weight at a rate of R kg/day.
