Can You Live on Energy Bars Alone?
Our experiment on a Men's Fitness staffer aims to find out.

Now that there are nutrition bars that provide not only the three energy sources, but also vitamins, greens, living Superfoods, herbal extracts and magic fairy grains, everything an adult human male needs for a day’s worth of nutrients can theoretically be supplied by a bar.
But what about actuality?
Without any hint of recommendationbecause this is utterly ludicrouswe consulted with New York-based dietitian Sharon Richter M.S., R.D., C.D.N. to craft a meal plan based on the stated nutrition facts of 11 different bars. But we not only intend to present the All-Bar Dietone of us is going to live on it.
Experiment: To see how a man would fare subsisting solely on nutrition bars for one week.

Meet Sunil Ramsamooj.
Height: 5'11"
Weight: 158 lbs.
Current Intake: 2,300-2,500 calories/day
Sunil works out, generally eats right and, despite making a religion of meal replacement shakes, has NEVER HAD A PROTEIN BAR BEFORE. Sharon has crafted a one-week plan based solely on bars and water that Sunil will adhere to strictly.
THE ALL-BAR DIET PLAN
Richter's daily regimen for complete, bar-based nutrition. Eat one of these per day with lots of water to compensate for the hydration not derived from consuming actual fruits and vegetables. (And to keep your poops from coming out like moon rocks.)
