Microdosing semaglutide or tirzepatide and feeling more fatigued than before. Sleeping worse. Workouts falling apart. You are not imagining it - and you are not alone.
GLP-1s suppress appetite significantly. Most patients are eating far less without realising they are also under-eating protein, calories, and critical micronutrients - particularly B12, magnesium, zinc, and iron. The result is mitochondrial underperformance, disrupted sleep architecture, and accelerated muscle breakdown.
Your body is running a caloric deficit and a nutrient deficit at the same time. Fatigue and poor sleep are the warning signal.
The fix is not stopping the medication. It is building the foundation around it. Adequate protein, targeted nutrient repletion, resistance training, and proper sleep support - matched to where your labs actually are.
GLP-1s are a powerful tool. But a tool without a foundation will always cost you more than it gives.
Share this with someone on GLP-1s who cannot understand why they feel worse not better.
