Weightloss Market Report: Sales Volume, Market Share, Leading Brands & Market Trends

Etekcity is the best-performing weightloss brand in July 2026, moving 100,000 units across 2 ASINs for 21.3% of Top 10 volume. Physician's CHOICE follows with 80,000 units (17.0%), ahead of WEEM on 70,000 units (14.9%).

Volume is spread across 8 brands, with the top three holding 53.2% 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 $17.49 to $34.95, 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. On the growth side, B01E3COD8K leads positive momentum with ▲ 50.0% MoM growth on 6K units, with B0083OJB6O close behind at ▲ 33.3% MoM on 4K 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already changed hands — an incumbent gave up its place to make room, so any competitive set drawn up a month ago is now out of date.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.
