Atkins Day 4 - Im feeling hungry :( help

  • Hi guys.

    Today is day 4 with me on Atkins.
    I followed instructions on keeping under 20g carbs a day.
    Got all the necessary protein and fat intake it requires.

    Day 1-3 was easy peasy.
    Then came today.
    I have this weird carb craving that was non existent on Day 1-3 and I feel hungry.
    My tummy is rumbling but not in a im gonna starve kind of way.

    Has anyone felt this before?
    Is this induction/keto flu?
