Protein helps the body burn more calories while digesting food.
When intake is low, metabolism may slow down, making it easier to gain weight even without eating more.
Protein keeps you full for longer by controlling hunger hormones.

Without enough of it, people often snack more, especially on sugary or refined foods that add empty calories.
Dr Geetika Chopra, Celebrity Holistic Nutritionist, told Onlymyhealth, “In my clinical experience, protein deficiency is one of the most common hidden reasons behind weight gain.”
Dr Chopra said that, especially in women, “low protein often shows up as hormonal imbalance, irregular cycles, and low energy.”
Protein is essential for maintaining muscle mass. Dr Chopra shared, “When the body does not get enough protein, it starts losing muscle mass.”
When muscle breaks down due to a deficiency, the body burns fewer calories at rest, increasing the risk of fat accumulation.
Without enough protein, excess calories are more likely to be stored as fat.
Over time, this imbalance can contribute to weight gain even if total food intake seems normal.
