The body is designed to adapt. When calorie intake drops significantly for an extended period, the body may respond by conserving energy.
This process, known as metabolic adaptation, can include:
• reduced energy expenditure
• increased hunger signals
• greater fatigue
• difficulty maintaining weight loss
This isn’t a lack of willpower.
It’s a normal physiological response intended to protect against starvation.
That’s why sustainable fat loss isn’t about eating as little as possible.
It’s about supporting metabolism through:
• adequate protein
• strength training
• quality sleep
• stress management
• realistic calorie deficits
The goal isn’t to eat less forever. The goal is to create a strategy your body can sustain.
