Forget crash diets and quick fixes—sustainable weight loss starts with understanding your body, not just your scale. That’s the message from María Amaro, a Spanish nutritionist whose evidence-based approach is reshaping how people think about healthy eating. In a recent interview, Amaro emphasized that lasting change requires a personalized strategy, not a one-size-fits-all meal plan.
“The goal isn’t just to lose weight—it’s to feel better,” Amaro said. “Too many people focus on the number on the scale or cut out foods at random, but that’s not how real progress happens. What works is a full medical evaluation that looks at the whole person, not just what they eat.”
Why Your Diet Isn’t Just About Food
According to Amaro, successful nutrition plans go far beyond counting calories or eliminating food groups. Instead, she advocates for a comprehensive assessment that examines lifestyle factors often overlooked in traditional dieting advice.
“It’s not enough to request someone what they had for breakfast,” she explained. “We need to understand their daily routine—when they eat, whether they cook at home or rely on processed foods, how much they move, how well they sleep, and even their stress levels. All of these influence how the body processes food and responds to dietary changes.”
Her approach also includes reviewing medical history, such as family risks for conditions like obesity, diabetes, or high cholesterol, as well as current medications that might affect appetite or metabolism. “Many people don’t realize that certain prescriptions can produce weight loss harder,” Amaro noted. “Without addressing those factors, even the best diet plan can fail.”
The Problem With Rapid Weight Loss
While fad diets promising fast results remain popular, health experts warn that losing more than 1 to 2 pounds per week can backfire. The American Dietetic Association and the Spanish Heart Foundation both recommend a gradual approach, citing risks like muscle loss, nutrient deficiencies, and even heart strain when weight drops too quickly.
“When people see dramatic results in the first few days, they often think they’ve found the secret,” Amaro said. “But much of that initial weight loss is water, not fat. Once they stop the diet, the pounds usually come back—and sometimes more.”
She pointed to a common misconception about carbohydrates as an example. “If you cut out carbs completely, you’ll lose weight fast because your body sheds water along with glycogen stores. But that doesn’t signify you’re healthier. Carbs are fuel, and eliminating them without a plan can lead to fatigue, cravings, and long-term metabolic issues.”
Building a Sustainable Plan
So what does a healthy weight-loss strategy appear like? Amaro outlines five key principles:
- Personalized assessment: A full medical and lifestyle review to identify individual needs and obstacles.
- Balanced nutrition: A diet rich in whole grains, lean proteins, fruits, vegetables, and healthy fats—without extreme restrictions.
- Realistic calorie goals: A moderate deficit (typically 300–500 calories per day) to promote steady fat loss without sacrificing energy.
- Lifestyle integration: Adjustments to sleep, stress, and activity levels to support long-term habits.
- Patience and consistency: Small, sustainable changes over time, rather than drastic overhauls.
“The people who succeed aren’t the ones who follow the strictest diet—they’re the ones who make changes they can stick with for life,” Amaro said. “That might mean eating more vegetables, cooking at home more often, or finding an exercise routine they enjoy. It’s not about perfection; it’s about progress.”
Why This Matters for Public Health
With obesity rates rising globally, experts say shifting the focus from short-term diets to long-term wellness could help reduce chronic disease risks. Amaro’s approach aligns with growing research showing that sustainable weight management depends more on behavior and environment than willpower alone.
“The biggest mistake people make is thinking weight loss is just about food,” she said. “But health is about so much more—how you live, how you cope with stress, how you sleep. If we want real change, we have to look at the bigger picture.”
