To achieve the above, add two panels and two menu items and then add the various controls to panel 1 (labels, check boxes, numeric up down, text box, combo box, and list box.

The  following code shows how to "grow" the panels to fit the screen as well as cycle between them.

private void menuItem1_Click(object sender, EventArgs e)
{
  panelEating.BringToFront();
}

private void menuItem2_Click(object sender, EventArgs e)
{
  panelExcercise.BringToFront();
}

private void Form1_Load(object sender, EventArgs e)
{
  panelEating.Dock = DockStyle.Fill;
  panelExcercise.Dock = DockStyle.Fill;
}

The final project.
