I rarely eat enough to get to my restriction. A 4 ounce can of tuna does not get me there but any more than that and it will hurt and be uncomfortable. Just eat what your teams tells you to eat, no more and no less. You will develop habits that are way more important than the physical restriction. Again, I rarely if ever reach the restriction. It is working for me since I have lost over 100 pounds and my BMI is almost in the normal range now.
