ZonePerfect was a manufacturer of health food products located in Columbus, Ohio.
They were known for their nutrition bars and shakes, created to comply with the Zone diet.
[citation needed] The brand was a part of the Ross Productions Division of Abbott Laboratories, and was commonly available in grocery stores in the United States.
All ZonePerfect meals were based on the ratio 40:30:30—in other words, the food they marketed was 40% carbohydrates, 30% protein, and 30% fat.
ZonePerfect frequently sponsored competitive events, such as the San Francisco Marathon.
