Weight Gainer as a meal replacement?

[givasum]

I'm 6'0", 172 lbs. Workout 5 days a week. Heavy weight low reps to failure. I have trouble eating throughout the day, so I assume my dificulty in adding muscle mass is due to lack of nutrition.

If I start using weight gainer as meal replacements throughout the day will it help me? Will it increase body fat?

Well, heavy weight and low reps doesn't say anything about your volume. Most often it's best to stay conservative with volume when trying to gain.

But, for the weight gans drinks, I'm not crazy about them. They tend to contain a lot of simple sugars that you don't really need except for right after your workout to spike insulin. For the rest of the day, that insulin spike will most likely result in more fat than muscle. I prefer a good protein shake 3 times a day. Have some carbs with the shakes to keep the meals balanced in the macronutrients. Eat every 2-3 hours depending on meal/shake size and alternate meals and shakes.
