OpenGL object load in reverse

I am trying to load a model and it is loading it in reverse. When I am trying to rotate it 180 degrees it changes the lightning as well. I am not sure what I need to do to change the position that eh model is facing when is being loaded.

This is the object loader:

if (!submarineShader->load("BasicView", "glslfiles/basicTransformations.vert", "glslfiles/basicTransformations.frag"))
{
    cout << "failed to load shader" << endl;
}
glUseProgram(submarineShader->handle());  // use the shader

glEnable(GL_TEXTURE_2D);

cout << " loading model " << endl;
if (objLoader.loadModel("submarine_/submarine v2/submarine5.obj", model))//returns true if the model is loaded, puts the model in the model parameter
{
    cout << " model loaded " << endl;

    model.calcVertNormalsUsingOctree();  

    model.initDrawElements();
    model.initVBO(submarineShader);
    model.deleteVertexFaceData();

}
else
{
    cout << " model failed to load " << endl;
}
