Everyday Uses

Fat isn't the enemy

Get your healthy fat range (20–35% of calories) so you stop fearing olive oil and start limiting the right things.

Saturated fat cap

Know your daily saturated fat limit in grams — the number that actually matters for heart health.

Reading labels with context

"15 g fat" on a label means nothing without your daily budget. Now the label has context.

Cooking decisions

Butter or olive oil, whole eggs or whites — make kitchen choices against a real target instead of vibes.

Omega-3 against omega-6

Both are essential, but typical diets carry far more omega-6 than omega-3. Oily fish, walnuts and flaxseed are the usual ways to shift the balance without cutting anything out.

Smoke point is a practical question

Heating an oil past its smoke point degrades it and produces off flavours. Which fat suits roasting, frying or dressing is a cooking decision as much as a nutritional one.

Frequently Asked Questions

How many grams of fat should I eat per day?

Dietary guidelines (USDA, WHO) recommend 20–35% of total daily calories from fat. Since fat provides 9 kcal per gram, someone eating 2,000 kcal/day should consume roughly 44–78 g of fat. Going below 20% long-term can impair hormone production and absorption of fat-soluble vitamins (A, D, E, K).

What is the limit for saturated fat?

The WHO and American Heart Association recommend keeping saturated fat below 10% of total calories — about 22 g on a 2,000 kcal diet (the AHA suggests an even stricter 5–6% for people with high cholesterol). Replace saturated fats (butter, fatty red meat, coconut oil) with unsaturated fats (olive oil, nuts, seeds, avocado, fatty fish) rather than with refined carbohydrates.

Are fats bad for weight loss?

No — dietary fat does not automatically become body fat. Total calorie balance determines weight change. Fat is the most calorie-dense macronutrient (9 kcal/g vs 4 kcal/g for protein and carbs), so portions matter, but adequate fat improves satiety, flavour, and adherence to a diet. Low-fat and low-carb diets show similar weight-loss results when calories and protein are equal.

What is the difference between saturated, unsaturated, and trans fats?

Unsaturated fats (mono- and polyunsaturated — olive oil, nuts, fish) improve cholesterol profiles and are linked to lower cardiovascular risk. Saturated fats (animal fats, butter, palm and coconut oil) raise LDL cholesterol and should stay under 10% of calories. Artificial trans fats (partially hydrogenated oils) raise LDL and lower HDL — there is no safe intake level, and they are banned in many countries.
