Beyond the Scale: Weird Fat Loss Signs
27 Jan
Summary
- Increased urination and feeling colder are common fat loss indicators.
- Altered sweat smell can signal the body burning fat for fuel.
- Hormonal shifts affect mood, sleep, and appetite during fat loss.

Fat loss often presents subtle, unexpected signals that extend beyond the scale or clothing fit. Gynaecologist Dr. Mallika Surve highlighted unusual physical, emotional, and behavioral changes people might experience.
These include increased urination, feeling colder due to reduced insulation, and altered sweat smell as the body uses fat for fuel. Random energy bursts and a leaner facial appearance are also noted.
Changes in body recomposition can cause clothes to fit unevenly. Improved sleep and mood fluctuations, followed by overall betterment, indicate hormonal shifts. Veins may become more visible, and appetite can vary as hunger hormones reset.
While generally normal, persistent extreme cold intolerance, strong sweat odor, dizziness, or excessive urination with fatigue warrant medical attention. These could indicate under-eating, dehydration, or electrolyte imbalance.
Hormones like leptin, ghrelin, and cortisol are affected, influencing mood, sleep, and appetite. Initially, leptin may drop, increasing hunger and irritability, while cortisol can rise due to calorie restriction, impacting mood and sleep.
As the body adapts, hormone levels stabilize, leading to improved mental clarity. Healthy fat loss is characterized by stable energy, regular menstrual cycles, good sleep, and maintained fitness. Excessive loss may manifest as fatigue, hair thinning, or hormonal irregularities.
