What Are MUFAs? | Ask the Fitness Nerd

What’s a MUFA? The Fitness Nerd explains what this funny acronym means and why MUFAs are suddenly the rage among dieters.

Dear Fitness Nerd:

What are MUFAs? I keep hearing people talk about them, but I still haven’t quite figured out what they are. I know they are a type of fat, but I thought fats were unhealthy and should be avoided. Are they a supplement of some type like CLA? - Kayla R, (West Hollywood, CA)

MUFAs are an acronym for a “monounsaturated fatty acids” — a class of healthy fats found in foods like nuts and seeds, avocados, olives and certain vegetable oils. MUFAs are not typically taken as a supplement (as Conjugated linoleic acid or CLA often is), since they are plentiful in foods. 

MUFAs have gotten a lot of attention recently for three reasons:

1. MUFAs may help you lose weight.

There is some evidence that people who regularly consume MUFAs have lower body fat levels and are more successful at dropping body fat and weight than people who are on low-fat, carbohydrate rich diets.

This research flies in the face of  the conventional-wisdom that drove the low-fat craze of the 80s and 90s, which advised people to reduce their fat consumption as much as possible in order to lose weight, lower cholesterol and reduce the risk of stroke, high-blood pressure and heart disease. The latest research actually suggests that diets which are higher in healthy fats like MUFAs may be more effective at weight-control than low-fat diets.

2. MUFAs may reduce the risk of disease.

A growing body of research shows that MUFAs may not only help people lose fat, but that they also have protective properties that may lower the risk of developing certain diseases, including Type II Diabetes, heart disease, stroke and possibly certain types of cancers. MUFAs are also part of The Portfolio Diet, which is an approach to eating that combines MUFAs with other cholesterol-lowering foods like soy, plant sterols and soluble fiber from things like oatmeal and may reduce blood cholesterol-levels as effectively as prescription statin drugs.

Dietary Fat: Five Myths About Fat | Diet Tips

Think eating less fat will make you thinner? Not necessarily. Answer Fitness debunks the five most common myths people have around dietary fat.

Navigating the sometimes contradictory research and information around dietary fat can make a person’s head spin. Should I eat more fat? Less fat? A different kind of fat? Here are the five most common myths around dietary fat:

Myth #1: Eating more fat makes you fatter

Not true.

Eating more calories than you burn makes you gain fat.

Whether those excess calories come from protein, carbohydrates or dietary fat, any calories that you eat above your daily energy requirements will get stored away as body fat. 

The issue with dietary fat is that it’s extremely calorie dense, meaning that it contains more calories per gram than other macro-nutrients like protein or carbohydrates. This means that gram-for-gram, foods with a higher fat content contain more calories (9 calories per gram of fat versus 4 calories per gram for carbohydrates and protein.)

So if you aren’t careful, you can end up eating more calories in foods with higher fat content, even though you are eating the same amount of food.
