Yes, folks, diet fatigue is real.
After you've restricted calories for a while, your body and brain start to push back. Hunger hormones rise and satisfaction hormones drop. Mental fatigue sets in. Motivation drops. You begin to feel tired and irritated. You begin to experience strong food cravings. You have reduced motivation. You feel like you've plateaued.
I've thus started on a diet break for a couple of weeks. I'm sure this will help.
