Healthy fats and the "light" products myth

By Dr. Andrea Pérez Jaramillo · Physician & nutritionist · Medically informed
Quick answer: Healthy fats (olive oil, avocado, nuts and seeds) are essential for your brain and hormones. The mistake isn't eating fat, it's choosing poorly. And many "light" products replace the removed fat with sugar and ingredients you don't need.

For years we were told fat was "the enemy." Today we know the secret isn't to eliminate it, but to choose well, and that many "light" products aren't as healthy as they seem.

Your body needs fat

A large part of your brain is fat, and your hormones need it to function. Fats also help you absorb vitamins and feel full. Cutting them out abruptly is neither necessary nor healthy.

Which to prioritize

The "light" trap

When fat is removed from a product, sugar, starches or additives are often added so it still tastes good. The result: a food that looks healthier but can have more sugar and less satiety. "Light" doesn't always mean "better."

How to choose

Read the ingredient list rather than the word "light" on the package. Prioritize real foods with quality fats, and be wary of products that promise a lot and have very long ingredient lists.

Frequently asked questions

Does eating fat make you gain weight?

Not on its own. Weight is influenced by your overall diet and portions, not a single nutrient. Healthy fats are part of a balanced diet.

Do "light" products help with weight loss?

Not necessarily. Many replace the fat with sugar or additives and are less filling. It's worth checking the ingredient list, not just the "light" label.

How much healthy fat should I eat?

It depends on each person and their goals. The ideal is to include quality sources in appropriate amounts; a personalized plan defines the portions for you.
