Nutrition experts clarify fat intake and weight loss myths

Experts are addressing common misconceptions regarding dietary fat and weight loss. While fat was long viewed as an enemy of healthy eating, it is essential for cell membrane structure and the absorption of fat-soluble vitamins.

The European Food Safety Authority (EFSA) recommends that fat should account for 20–35 percent of daily energy intake for adults. The World Health Organization (WHO) suggests a slightly stricter upper limit of approximately 30 percent to prevent unhealthy weight gain. For a woman on a 2000-calorie diet, this translates to roughly 44–78 grams of fat daily, though exact requirements vary based on age, activity level, and body type. The WHO emphasizes prioritizing unsaturated fats and keeping saturated fat intake below 10 percent of total energy.

Regarding weight loss, experts warn against common myths such as extreme calorie restriction. Drastic reductions are difficult to sustain and can lead to metabolic adaptations where the body requires less energy as weight decreases. Harvard experts note that appetite may increase after weight loss while energy expenditure drops, making long-term maintenance challenging. Sustainable weight management depends on a combination of diet composition, physical activity, sleep, and stress management rather than quick-fix methods.
