His workout is very intense. How many hours does he sleep ? Since he is an ectomorph like me, he needs at least 8 hours of sleep. Also unlike other people, ectomorphs tend to carry less body fat, so it is less likey that he will get overweight like those fat guys.
link Also he needs to consume milk. Read this.
link Just surf this website for getting more tweaks for ectomorphs.
HOWEVER
A word of caution. I would suggest that he begin by drinking only 2
litres milk a day. Also ask him to do stomach exercises like crunches &
leg raises so that his stomach doesn't bloat. Now the reason why his
stomach will bloat is because milk satiates.Ask him to do a complete
workout of stomach comprising of the upper abs, middle abs & lower abs
exercises.

Now the thing is that milk increases testosterone levels (T levels)
significantly. I know this because I have tried this. Since his workout
is highly intense, he needs to consume whole milk. With milk I give you
the guarantee that he will gain weight. His weight will increase.
Also since milk is easier to digest, he may have to go to the loo often
for some number of days till his body gets adjusted to the milk
consumption.
Calorie Consumption for weight gain:
20 * (his weight in pounds)
So in your case 20 * 195 = 3900 approx. 4000 calories.So, he msut consume milk & his food in such a way that he consumes a total of 4000 calories per day.
After gaining his target weight, he must consume calories in order to
maintain it, given by the formula :
15 * (his weight in pounds) + 500
With daily milk consumption, his energy levels, stamina & muscles will
increase by 30% or more depending on his resting period & workout.
All the Best :-)
