On a low-calorie diet, your body notices that it’s receiving fewer calories, so it sheds some weight initially. While this is happening, your body’s ability to produce, distribute, and balance key hormones (the interplay of hormones is what makes up metabolism) efficiently becomes compromised, and though you may lose a few pounds, (or even more than a few), your system is otherwise sent into distress. When this happens, your health—including your body’s ability to regulate weight—is thrown out of whack. Your body says, “Okay, gorgeous, it’s just a matter of time before you and I either (1) plateau on that particular diet and stop losing weight or (2) throw in the towel and give in to our debilitating hunger, fatigue, moodiness, sleep deprivation, cravings, and other symptoms of metabolic distress.
