Metabolic profiles influence weight loss outcomes

With over 60% of the Brazilian population living with excess weight, medical experts emphasize that metabolic individuality significantly impacts the success of weight loss treatments. Nutrologist Sebastião Viana Júnior explains that individuals with similar weights and routines can achieve vastly different results due to a combination of hormonal, genetic, behavioral, and body composition factors.

Obesity is classified as a multifactorial disease, meaning effective treatment requires looking beyond simple calorie counting. Key variables include visceral fat percentage, muscle mass, insulin sensitivity, sleep quality, and energy expenditure. Hormonal issues, such as thyroid axis alterations, and genetic variants related to hunger and satiety also play critical roles in how a person responds to weight management protocols.
