Let ((M^n,g)) be a real analytic compact n-dimensional Riemannian manifold and denote by (varphi _{lambda }) the eigenfunctions of the Laplace operator (Delta _g) with eigenvalue (lambda ^2). We prove that if (H subset M) is a real analytic closed curve for which there exist (lambda _0, C>0) so that (Vert varphi _lambda Vert _{L^2(H)} ge e^{-C lambda }) for all (lambda >lambda _0), then
$$egin{aligned} # {varphi _lambda ^{-1}(0) cap H } = O (lambda ). end{aligned}$$
