Wilhelm Ebstein (27 November 1836, Jauer, Prussian Silesia – 22 October 1912) was a German physician.

Ebstein was born to a Jewish family in Jauer, Prussian Silesia (modern Jawor, Poland).

[6] He authored Die Fettleibigkeit (Corpulenz), which recommended a low-carbohydrate, high-fat diet for treating obesity.

[7] His daily menu permitted "two or three glasses of light wine" but shunned beer.

[1] Ebstein's specialties were studies of malassimilation and improper nutrition, of which he introduced a number of new procedures for treatment.
