4. Buying Brand-Name Instead Of Generic

From groceries to clothing to prescription drugs, you could save money by choosing the off-brand over the fancy label. And in many cases, you won't sacrifice much in quality. Clever advertising and fancy packaging don't make brand-name products better than lesser-known brands.

5. Health Supplements

The fitness industry has somehow convinced us being young men between 15 and 30 looking to improve our bodies -- that the path to a frugal physique is paved with fat burners, pre-workout vasodilators, protein powders and testosterone-boosters culled from bull testicles or rhinoceros horns. It's not unusual for a weight lifter to spend over 1000 per month on supplements, most of them useless.

What do you need to gain size and strength? Eat more calories than you burn. A good protein powder can actually save you money by helping you reach your daily goal of protein intake cheaply, but outside of that and possibly a fish oil supplement, you're best off getting your nutrients through food.
