Fats are one of the main macronutrients of nutrition and by themselves don’t determine weight gain. Even though they have more energy per gram compared to protein and carbs, that doesn’t mean they’re “fattening”.
Gaining or losing weight depends on your overall energy balance — basically, whether, over time, you take in more or less energy than you burn. No single macronutrient can cause weight gain by itself, regardless of the whole diet.
What’s the role of fats?Fats are essential for:
absorbing fat-soluble vitamins (A, D, E, K)
proper hormonal function
the health of your nervous system
At the same time, they add flavor and texture to meals, making them more enjoyable and easier to stick with long-term.
Fats and satietyFats also help with a feeling of fullness. A meal with enough fat can keep you satisfied for longer, cutting down the chance of overeating later in the day.
What to rememberThe point isn't to avoid fat, but to focus on balance and quality in your overall diet. When fats are eaten in moderation and the right way, they aren't a problem, but actually support a healthy, long-term and enjoyable way of eating.
