Do you have a love/hate relationship with FATS?

For decades, Americans have been bombarded with conflicting arguments both for AND against this essential macronutrient. Should we eat them? Should we not? What kind of fat should we eat?

But the confusion stops here. My no-nonsense, easy to understand guide to all things fat will show you why breaking-up with your beloved fat is not the way to go.

Why do we need fat?
-Critical for the production of cells and hormones in our bodies
-Important for proper brain functioning
-Provides energy
-Regulates the nervous system
-Controls blood pressure, heart rate and blood clotting
-Essential for the absorption of vitamins (particularly A, D, E, K)

How much do we need?
The daily recommended consumption of total fat in our diet should fall between 20-35%, with 10% or less saturated fats and 1% or less trans fats.

So, if you eat 2,000 calories a day, and 30% of that is fat, you are consuming 600 calories of total fat in your diet.

A common misperception about fats is that the good-for-you fats are also lower in calories. While some fats are healthier than others, they all share the same caloric density (~9 calories per gram). But don’t let that scare you.

Who are the key players? (from worst to best)

Trans Fat
Why it’s the worst:
-Raises LDL (bad guy) cholesterol
-Lowers HDL (good guy) cholesterol
Found in: Stick Margarine; Baked goods; Fried foods; Any foods with “hydrogenated” or “partially hydrogenated” in the ingredient list

Saturated Fat
Why it’s bad:
-Raises LDL (bad guy) cholesterol
Found in: Animal fats (meat, whole milk, ice cream, cheese, butter); Certain plant oils (coconut oil, palm oil, cocoa butter)

Polyunsaturated Fat
Why it’s good:
-Lowers total cholesterol
Found in: Vegetable oils (safflower, corn, sunflower, soy oils)

Omega 3 Fatty Acids (type of polyunsaturated fatty acid)
Why it’s better:
-Lowers total cholesterol
-Lowers triglycerides
-Decreases blood clotting
-Decreases inflammation
Found in: Fatty fish (salmon, mackerel, herring), Walnuts, Flaxseeds (and flaxseed oil)

Monounsaturated Fat (MUFA)
Why it’s the best:
-Protects against heart disease (lowers LDL cholesterol, raises HDL cholesterol)
-Prevents obesity related diseases such as diabetes and metabolic syndrome
-Maintains brain function
-Decreases inflammation
-Reduces risk of prostate cancer
-Targets stubborn belly fat
Found in: Oils (Canola, safflower, sesame, soybean, walnut, flaxseed, sunflower, olive and peanut oils); Olives; Nuts and Seeds; Avocados; Dark chocolate

Here’s a simple mantra to follow:

Instead of LOW/NO fat, think GOOD fat…and in moderation.
