About Fat
Fat is the body's most calorie-dense fuel, 9 kcal per gram versus 4 for carbohydrate and protein, and the carrier for fat-soluble vitamins A, D, E, and K. It builds cell membranes, makes hormones, and cushions organs.
Not all fats behave the same way. Polyunsaturated fats (omega-3 from oily fish, omega-6 from seeds) include essential fatty acids the body can't make. Monounsaturated fats (olive oil, avocados, nuts) are generally heart-friendly. Saturated fats (butter, fatty meat) raise LDL cholesterol in most people. Trans fats (industrial hydrogenated oils, now largely removed from UK food) are the most harmful and should be avoided.
UK guidance: total fat under about 35% of daily calories, with saturated fat under 11%. Replacing saturated fat with unsaturated fat, not with refined carbohydrate, is associated with better cardiovascular outcomes.

Common questions about Fat
- Is fat bad for you?
- Whole-fat foods aren't the villain they were treated as decades ago. Fat is essential for hormones, cell membranes, and the absorption of fat-soluble vitamins. The type of fat matters far more than the total.
- Which fats are healthiest?
- Monounsaturated fats (olive oil, avocado, nuts) and polyunsaturated fats (oily fish, seeds) are generally heart-friendly. Saturated fat raises LDL cholesterol in most people. Trans fat should be avoided.
- How much fat should I eat?
- UK guidance: under about 35% of daily calories from fat, with saturated fat under 11%. There's no need to count grams, focus on the source profile (more unsaturated, less saturated).
- Do I need to eat fat to absorb vitamins?
- Yes. Vitamins A, D, E, and K are fat-soluble, they need some dietary fat in the meal to be absorbed properly.
