Medifast, Inc.
A maker of meal-replacement and metabolic-health products, Medifast sells its foods and coach-guided programs under the Optavia and Trilivy brands, used by people looking to manage their weight and metabolic health. It was founded in 1980 by Dr. William Vitale, a Baltimore dermatologist who started mixing his own liquid-diet formula after struggling to source products from other providers. The name is a blend of "medical" and "fast," a nod to the medically supervised, quick weight loss the company was built around.

Select a row to see that insider’s individual transactions. Sum of the holdings confirmed in the 12 months before this insider's last filing. A Form 4 reports a holding per line — held directly, or through a named trust, partnership or foundation, and in each share class separately — never a person’s total. Lines not restated in that time are left out and shown apart: an active filer restates what they still hold, so a line they did not restate is more often an entity since renamed, whose shares a successor line reports too. An amber marker means some were left out.
Net open-market activity over all recorded history: -3.55M shares. Grants, option exercises and tax withholding are excluded — they are compensation mechanics, not decisions to buy or sell.
