With the global meal replacement market expected to reach more than $12 billion by 2020, manufacturers are concentrating more on gluten-free products that meet consumer tastes and preferences, according to a report by Technavio.

The largest meal replacement market is in the Americas and is valued at $5.45 billion in 2015. The U.S. market is driven by several factors, including a rise in disposable income and awareness of proactive healthcare practices in light of rising healthcare costs. The aging population is also on the rise, which has fueled demand for ready-to-drink shakes and energy bars.

Globally, the second largest region for gluten-free products as a meal replacement is Asia Pacific, where the market was valued at $2.44 billion in 2015. The rapidly expanding economies of India, China, and Japan are driving proactive personal healthcare practices, and people are opting for meal replacement products to cut down their calorie intake while obtaining protein and minerals.
