The Science Behind Sustainable Weight Loss: What Actually Works?

When it comes to weight loss, the basics still matter: a calorie deficit, consistent movement, and hormonal balance. But science shows that one-size-fits-all doesn’t work. Factors like age, sex, sleep, and insulin resistance all affect how your body sheds pounds.

Recent research from Mayo Clinic emphasizes the role of metabolic adaptation — your body’s tendency to conserve energy when you eat less. This is why crash diets fail and long-term lifestyle changes succeed.

Quick Tips That Work:

• Eat more protein to retain lean muscle mass.

• Focus on fiber-rich whole foods to stay fuller longer.

• Stay consistent with daily movement — even walking counts.

• Get your hormones checked if weight loss is unusually hard.
