Low Carb Market Report: Sales Volume, Market Share, Leading Brands & Market Trends

Premier Protein is the best-performing low carb brand in July 2026, moving 110,000 units across 2 ASINs for 19.6% of Top 10 volume. Monster follows with 80,000 units (14.3%), ahead of 365 by Whole Foods Market on 80,000 units (14.3%).

Volume is spread across 9 brands, with the top three holding 48.2% between them. No single label controls the shelf, which usually leaves room for a well-differentiated listing to take share without outspending an incumbent. Average selling prices among the leaders run from $5.29 to $27.98, which frames the price band a competing listing has to justify.

Based on July 2026 data, this shortlist surfaces the two kinds of ASIN worth keeping an eye on — the ones that just broke into the Top 10, and the ones growing fastest month over month. Specifically, one ASIN forced its way in: B006WBVSV6 booked 40K units at $6.49, with ▲ 0.0% MoM change. On the growth side, B06ZZ3PJQD leads positive momentum with ▲ 200.0% MoM growth on 30K units, with B016MEN14O close behind at ▲ 66.7% MoM on 10K units.

The two signals carry different weight. A fresh entrant means share has already changed hands — an incumbent gave up its place to make room, so any competitive set drawn up a month ago is now out of date. A steep growth rate works as the earlier warning: it marks demand that is still compounding, usually a month or two before the ranking catches up to it.
