Yes, always better to tough it out and keep the momentum going IMO. Reason being, as you cut you are actually slowing your BMR as your body adapts to new deficit. Then when you decide to maintain for a bit and take a “break,” you’re still actually miserable and feeling hungry all the time because it’s still a deficit to your original starting point. And if you go back to eating your original maintenance, you’ll actually gain the weight back. So my thinking is, if you’re already suffering and hungry, just stick with the cut and get it done in 12 weeks instead of yo-yoing for 6 months and still not reaching your goal.
