EDIT: I've merged your post yeezai

Let me dig this out of my brains (DIGS)

Your weight increase was thanks to the increase in calories. Your added protein gave your body the building blocks to start reconstruction as your body was broken down via exercise. Carbs became the catalyst to your muscle reconstruction via synthesis of the amino acids.

If your body has reached the desired weight, and caloric intake remains consistent to the minimal intake your body needs for maintenance of weight, it will not drop. However, if there's a decrease below your maintenance caloric requirement, you will drop in weight.

It's as simple as that.

calorie intake > calories needed = gain weight
calorie intake < calories needed = lose weight
calorie intake = calories needed = no gain no lose

u figure out from here la.. depends on ur lifestyle, body metabolism, how many calories u use everyday for gym etc.

say if u take 2500 cal/day and u use 2000 cal/day for gym, work, etc, then ull gain weight.. but if u take out the 2 meal replacement drink to 2000 cal/day, and ur still using 2000 cal/day for gym, work etc then ull not lose weight nor gain weight.. simple no ?

im not good as pizzaboy, lets keep it simple.
the ectos need a bit simulation to grow. Lets say u eat xxx amount of calories b4, and didnt exercise, ur weights still the same.
u do weights training, and consume xxx calories, u see improvement, your body finally know what to do with all the calories u consumed. lulz
imagine your body as a car. you as a Kancil before. your consume only a little bit of fuel.
and now you're a Lamborghini, you consume more fuel, even at red traffic light, compared to Kancil idling right? makes sense?
bigger car = more fuel
more bigger body needs more calories, doesnt matter which they come from, natural foods or supplements

you can dump amino. choose one whether gainers or whey protein.
gainers + creatine or whey + creatine shud be enough.
the rest invest on solid foods

come to think of it, food just to live is actually pretty cheap and affordable.. food for being vain and strong costs an arm and a leg.. :/

how nice if we actually needed carbs to build muscle and not protein! that would be awesome.. i become rice bowl that time..

Weight gainers very the expensive oh.
Can cut cost by mixing whey with carbs/oats/glucose what.

BTW, anybody tried mixing sucrose (normal sugar) instead of glucose/dextrose into whey for pre- & during workout drink? (I don't have glucose with me right now)

Is the effect the same? I reckon sugar is pretty much a simple carb and easily digested anyway.

haha..well if you buying gainers..or just normal whey
try to do less scoops from what they tell you..
and just blend it with a few scoop of oats and some peanut butter..
some flax seed oil...some honey haha...

there you go budget gainer with i think 1000cal..
if not mistaken

well im muscle juice pretty economical for a 5kg tub..
and i still add oats,peanut butter and honey...

Honey, anything can gain weight as long as there's enough calories. Many people take excessive protein shakes and wonder "Why am I not gaining weigh?" Ever noticed that a scoop of protein is only 100-130 cals? If 110/3000 cals, you'd need 27 scoops of shakes a day to MEET your average ectomorph requirement.

You mix sugar+creatine for pre, you might experience a sugar crash about 40-45 minutes into your workout and that's when you have to drag yourself to do a single row. My friend has this issue. I don't. In fact, I don't have ANY of issues most people have when training.....weird.....

http://rosstraining.com/articles/strengthtraining.html <---read this entire article first. It's a goldmine of information.

Let's just say that, if you feel you're losing weight after stopping the supplement intake, (which I highly doubt provided you have sufficient food) then you can easily just eat a few more eggs in the morning, a few more chunks of beef and lamb or any meat source. GO to my friend's blog, coachjon.com/blog. I think he has an article about this put very simply. Something about bricks and workers and money = protein, carbs and fat.
