As more people embrace healthier lifestyles, many expect that improved nutrition and regular exercise will completely transform their bodies. However, health specialists in Brazil say that achieving a target weight does not always eliminate concerns about body shape or appearance. In many cases, anatomical changes caused by ageing, pregnancy or significant weight loss cannot be corrected through lifestyle changes alone.
According to Brazil's Ministry of Health, data from the Vigitel surveillance system show that 57.5% of Brazilian adults are overweight, while 24.3% live with obesity. These figures have contributed to growing interest in weight management, fitness and preventive healthcare across the country. Yet specialists note that improvements in health do not always translate into satisfaction with body image.
Dr Marco Dallegrave, a plastic surgeon and member of the Brazilian Society of Plastic Surgery (SBCP), says one of the most common misconceptions among patients is the belief that every physical concern can be solved through diet and exercise alone.
"There is a widespread belief that every form of body dissatisfaction can be resolved through healthy eating and physical activity. These habits are fundamental for health and should always be encouraged, but some physical changes are not simply related to body fat or muscle strength."
With more than two decades of experience and over 5,000 surgical procedures performed, Dr Dallegrave says he frequently meets patients who feel frustrated despite reaching their weight-loss goals. In many cases, the underlying concerns involve excess skin, skin laxity, abdominal muscle separation (diastasis recti) or changes associated with pregnancy, ageing or substantial fluctuations in body weight.
He emphasises that plastic surgery should never be viewed as a substitute for healthy living or as a quick solution to body image concerns. Instead, treatment decisions should be based on careful medical evaluation, patient safety and individual physical and emotional needs.
"Surgery only makes sense when there is a genuine medical indication. The objective is not to transform someone to meet aesthetic standards, but to help patients regain comfort, function and a healthier relationship with their own body. Improving self-esteem can also contribute to overall quality of life."
Seven signs that may warrant a specialist assessment
According to Dr Dallegrave, several situations may indicate that a medical evaluation could help determine whether anatomical factors, rather than lifestyle alone, are responsible for persistent concerns.
1. Excess skin remains after significant weight loss
Following major weight loss, particularly after bariatric surgery or major lifestyle changes, excess skin may remain around the abdomen, arms, thighs and breasts. Beyond cosmetic concerns, loose skin can lead to skin irritation, discomfort during physical activity and limitations in daily life.
"For many patients, excess weight is no longer the main issue. What begins to affect their quality of life is the remaining excess skin."
2. Skin laxity does not improve despite strength training
Building muscle improves body contour but cannot restore skin elasticity lost through ageing, pregnancy or major weight fluctuations. While resistance exercise remains essential for overall health, it cannot fully reverse structural changes in the skin.
3. The abdomen remains prominent despite low body fat
Not every persistent abdominal bulge results from excess fat. In some individuals, particularly after pregnancy, the cause may be diastasis recti, a separation of the abdominal muscles.
"A clinical assessment helps determine whether the issue is localised fat, loose skin or a muscular condition that requires a different approach."
4. Dissatisfaction is limited to one specific body area
Some individuals maintain a healthy weight and active lifestyle but remain concerned about isolated areas such as the chin, upper arms, breasts, flanks or abdomen. According to Dr Dallegrave, anatomical structure and genetics often influence body shape independently of physical fitness.
5. Physical discomfort affects daily activities
When excess tissue causes skin irritation, limits clothing choices, interferes with exercise or creates discomfort during routine activities, the issue extends beyond appearance and may affect overall wellbeing.
The surgeon notes that functional limitations are an important part of any comprehensive medical assessment.
6. Weight goals have been achieved, but body image concerns remain
For some people, reaching a desired weight does not eliminate dissatisfaction with their appearance.
"The most important step is understanding the source of that dissatisfaction. Not every concern will be resolved through surgery, just as not every concern will disappear with diet alone. Every patient deserves an individual assessment."
7. Increasing dietary restriction or exercise no longer changes the outcome
When people continue to intensify dieting or increase training volume without seeing improvements in specific physical concerns, the underlying issue may not be related to body fat. Structural anatomical factors sometimes require different forms of management.
Dr Dallegrave stresses that plastic surgery should never replace healthy habits or be considered a treatment for emotional distress.
"Plastic surgery is not a substitute for healthy living, nor should it be viewed as a solution to emotional issues. It may be appropriate when there is an anatomical limitation that does not respond to lifestyle changes. The ultimate goal is to improve wellbeing, function and a healthier relationship with one's own body."
As awareness of preventive health continues to grow in Brazil, specialists encourage individuals to adopt a balanced perspective on body image. Nutrition, physical activity and mental wellbeing remain the foundation of good health, while medical assessment can help determine whether persistent physical concerns are related to anatomical changes rather than lifestyle alone. Ultimately, experts agree that successful health outcomes should be measured not only by the number on the scales, but also by comfort, function and long-term quality of life.
