Obesity Is Far More Complex Than “Eat Less, Move More” and Treating It Requires Compassion, Not Judgment
For too long, society has viewed obesity through a narrow and punishing lens as a failure of willpower rather than what it truly is: a chronic, multifaceted disease influenced by biology, environment, psychology, and culture.
Dr. Fatima Cody Stanford, a physician, researcher, and instructor at Harvard Medical School, has spent years unraveling this complexity. In her work at the Massachusetts General Hospital Weight Center, she reminds us that obesity isn’t about moral weakness, it's about human physiology. Her research dives deep into how the body regulates energy, how genetics shape metabolism, and how the forces of modern life from hormones to food marketing conspire to make weight management far more complicated than “calories in, calories out.”
The Myth of “Calories In, Calories Out”
If obesity were simply a math problem, we would’ve solved it decades ago. Yet, as Dr. Stanford explains, this outdated equation eat less, burn more fails to capture the intricate mechanisms of the human body.
Our weight is not a static number on a scale. It’s a dynamic reflection of hormones, metabolism, environment, and emotional patterns. Genes determine how efficiently we store fat, hormones dictate how hungry or full we feel, and the stress of modern living pushes us toward comfort foods that offer momentary peace but lasting consequences.
Dr. Stanford argues that this oversimplification paired with stigma and shame has fueled, not fixed, the obesity epidemic. In the U.S., over 36% of adults live with obesity, and the numbers are rising worldwide. Judgment and blame don’t motivate people to change; they drive people away from the help they need.
Relearning How to Live: The “Healthy Habits for Life” Program
At the MGH Weight Center, Dr. Stanford and her colleagues take a radically human approach. Their Healthy Habits for Life (HHL) program begins with what medicine often forgets education, empathy, and support.
Led by registered dietitian Abeer Bader, this 12-week program blends science with compassion. Each week, participants meet for 90-minute sessions that go beyond meal plans and calorie charts. They talk about how obesity happens, how to make nutritious food taste good, and how to dine out or grocery shop without guilt.
The program’s foundation is inspired by the Mediterranean and DASH diets, nutrient-rich, flexible eating styles focused on real food: colorful vegetables, fruits, whole grains, and lean proteins. They use the Harvard Healthy Plate as a visual guide for balance and portion awareness.
But the secret ingredient, says Bader, is personalization. “We work with patients to set realistic, self-driven goals,” she explains. “When patients define their own priorities, their motivation and adherence soar. It’s not about telling them what to do, it's about helping them discover what works for them.”
This approach mirrors findings from the Diabetes Prevention Program, which showed that lifestyle-based interventions can help participants lose 5–7% of their body weight and reduce the risk of developing diabetes by as much as 71%.
The Diet That Works Is the One You Can Live With
“The best diet,” Bader says, “is the one you can follow for life.”
In other words, success isn’t found in restriction, it's found in sustainability. Whether it’s plant-forward eating, mindful meals, or moderate carb reduction, research consistently shows that nearly all evidence-based diets work about equally well in the short term. The real differentiator is whether a person can make those changes part of daily living, not a passing phase.
Medications and the Biology of Weight
While lifestyle changes form the foundation of obesity care, medications are increasingly part of the solution and they’re often misunderstood.
Modern anti-obesity drugs don’t just “burn fat.” They work within the brain’s weight-regulation system, helping to reset the body’s natural “set point” that dictates hunger, fullness, and metabolism. Yet, as Dr. Stanford notes, medicine still underutilizes these tools partly due to lingering stigma, and partly because no single medication works the same for everyone.
“Sometimes,” she explains, “there’s no clear reason why one person responds beautifully to a medication while another doesn’t. That’s just how unique human biology is.”
Rethinking How We Talk About Obesity
Treating obesity isn’t about blame, it's about biology, behavior, and belief systems. It’s about dismantling the myths that make people feel broken and replacing them with knowledge that empowers healing.
The path to better health isn’t a punishment or a quick fix. It’s a process that requires medical care, community, and compassion. As Dr. Stanford and her team continue to prove, when people are seen and supported, rather than shamed, they can reclaim not just their weight, but their well-being.
