to gain weight? just easy... MORE FOOD. that easy...   

no gain weight after eating "alot"? then u actually not eating enough.. 

here my advise as a personal trainer.
depends on wht u eat =)

Rubbish tht put in ur stomach doesnt really count.
1st step alwiz the hardest =) but try to follow my method instead

try to consume 5meals per day. u can start off with 3/4
BREAKFAST is the most important meal each of ur day cuz this to kick off ur metabolism
try to include in ur breakfast lunch and dinner.

Fruit
Vegetables
Nutrient
Protein

Between ur lunch and dinner u can consume some dessert such as yoggurt/fruit/shake
As u r a hard gainer u can eat supper =) u must asking izzit good to take supper?
depends on wht u take. i would recommend u to take bran oatmeal cuz is a slow release carbo.
Till then u can tahan till tmr.
Rules NO.1 never get starved
Eventually every 3hours try to consume 1meal.
Good tht u do running as cardio but i suggest u dont do too much of cardio.
If ur a gym member go for weight training otherwise juz find any public park do some bar exercise .

hope this helps.
cheer mate.

Tanker? Then i am gozilla then.
Go learn up what is calories 1st. What your daily calories need. And eat more than you calories need per day. That easy.
Whatever high amount or frequency, make sure  you eat exceed your daily calories need.

i will recommend you to eat boiled potato and fried things twice a day and boiled rice 3 times a week.It will help you a lot.I tried all these things itself and it works on me

If you still eating the same amount of food while you were below 60kg, surely you cannot gain weight.

The science behind it is that, your BMR increased as your muscle do. Simple meaning is that, if you need to eat 2500kcal to gain muscle mass by 3kg, to gain another 3kg of muscle mass, you need to eat more than 2500kcal a day as your BMR will increase.

That is why pro bodybuilders need to eat a lot of food (more than 5000kcal a day) due to amount of muscle mass the body have.

u have showed progress....great!

plateau at 60kg....up your calorie intake but yeah it is a real challenge to gain weight during uni days as money constraint, lack of discipline in keeping regular eating habit n workout session... try up more u'll notice it is even easirer to attract chick attention

I'm an ektomorf, but I think using a gainer isn't a good idea. Imho they are full of shitty carbs, why don't you just eat a cup of sugar?
I would prefer rice, oats, buckwheat, vegs etc.
