Market Growth Factors
Owing to moderate growth in protein bar demand, due to an increase in health-conscious consumers who prefer convenient food to meet daily nutrient requirements, and the high prevalence of obesity and diabetes, consumers are likely to prefer protein snacks over sugary snacks. According to WHO global data from 2022, 1 in 8 people around the globe is affected by obesity, as well as 43% of adults.
Today’s society wants convenience food like protein bars. Workers who work, parents who labor from home, or students have no time to prepare and consume varied healthy foods. CLIF BUILDERS launched Oreo-flavored protein bars during May 2025. The bars contain 20g of plant protein. There are portable, quick, and nutritious bars designed for replacement of lost energy quickly.
Flavor innovation, the addition of superfoods, organic ingredients, vitamins, and caffeine contribute toward market growth. In 2023, Barebells Functional Foods LLC launched banana caramel soft protein bars for attracting consumers and serving their market needs. The bars have 16 grams of protein and no added sugar.
