  Lattice simulations are the only viable way to obtain ab-initio Quantum
Chromodynamics (QCD) predictions for low energy nuclear physics. These
calculations are done, however, in a finite box and therefore extrapolation is
needed to get the free space results. Here we use nuclear Effective Field
Theory (EFT), designed to provide a low energy description of QCD using
baryonic degrees of freedom, to extrapolate the lattice results from finite to
infinite volumes. To this end, we fit the EFT to the results calculated with
nonphysical high quark masses and solve it with the stochastic variational
method in both finite and infinite volumes. Moreover, we perform similar EFT
calculations of the physical point and predict the finite-volume effects to be
found in future Lattice QCD calculations for atomic nuclei with mass number
$A\le4$.
