Taking leaves may decrease light absorption so the growth. it never increases light but it help better light distribution which can effect shape of the plant.
leaves not only are light collectors but also nutrients reservoir. They take lots of light and nutritions to be built. So Instead of removing them, push them down, below the foliage they have shaded as they are in high value for plants.
some growers heavily remove leaves and claim it is a good strategy. Yes, it is true. It is a good strategy but very bad methodology specially during vegetative phase. They are several plant trainings they can follow instead of removing leaves.
TAKING LEAVES=LOSING TIME, MONEY AND ENERGY.
