[vc_row][vc_column][vc_column_text css=””]Sandy has been on some form\u00a0of diet\u00a0for what seems like her whole life. They called her \u201cbig boned\u201d in her youth,\u00a0but it\u00a0<\/strong>was just a kinder way of saying overweight. As she entered her teen and adult years,\u00a0Sandy became both\u00a0a chronic\u00a0dieter and\u00a0a yo-yo\u00a0dieter \u2013 both unsuccessfully. The more she cut her calories\u00a0or carbs,\u00a0the more her body refused to drop a size \u2013 or reflect the waistline she wanted.<\/p>\n

Across four states, Danielle is working toward her dream figure, too. She wants to achieve it with exercise\u00a0\u2013 always looking to improve muscle tone and stay lean. You\u2019ll catch her at the gym\u00a02-3 hours\u00a0per day engaged in long-duration cardio sessions, high-intensity interval training,\u00a0and power\u00a0weight lifting. What you won\u2019t see Danielle doing is breaking for\u00a0lunch or eating a protein bar. This over-exerciser\u00a0is eating all wrong and\u00a0wonders why her body never seems to change.<\/p>\n

So, why aren\u2019t these ladies seeing results from their clearly proactive efforts?\u00a0A low-calorie diet and vigorous exercise help you lose\u00a0weight, right?\u00a0Not necessarily. Enter metabolic adaptation.<\/p>\n

What Happens When Metabolism Adapts?<\/strong><\/h1>\n

Sandy\u2019s mantra of \u201ceat less, weigh less\u201d isn\u2019t working for her because she\u2019s in starvation mode. And the same goes for Danielle and her \u201ceat less, exercise more\u201d regime. Sure,\u00a0they may have lost a little (or even a lot of)\u00a0fat, but their bodies cannot sustain this for too long. If you have a calorie deficit and\/or are over-exercising, your metabolism has adapted so\u00a0well that\u00a0you\u2019re no longer able to lose fat.<\/p>\n

When weight loss slows down, people like Sandy and Danielle eat less and\/or push harder in their\u00a0exercise routines,\u00a0forcing metabolism to slow…exponentially. Our bodies are constantly working to maintain homeostasis, which\u00a0means rapid\u00a0<\/strong>increases and decreases in consumed calories can cause issues. When we restrict our calories, our metabolism attempts to close the gap by decreasing our metabolic rate with leptin, the metabolism-regulating hormone. When leptin is high, metabolism is high; when it\u2019s low, our metabolism rate plummets. This explains why a diet may work well for a month or so, and then less so as our bodies work toward homeostasis.<\/p>\n
