10 “Superfoods” That Can Slow Your Weight Loss

“Superfoods” are nutrient-dense foods with a reputation for fighting disease, slowing aging and boosting immunity. Many of them are good for your health. But plenty of them aren’t great choices when your goal is to lose fat, and it’s easy to overeat them precisely because they have a healthy halo.

Two things matter most for fat loss: foods that fill you up for their calories, and eating habits that are easy enough to stick with. Here are 10 popular superfoods that often work against one or both, and what to do instead. (If you want the bigger picture, start with The Serious Guide to Nutrition.)

The short version

  • “Healthy” and “helps you lose weight” aren’t the same thing.
  • Calorie-dense foods (nuts, nut butters, oils, granola, dried fruit) are easy to overeat. Measure them.
  • Drinks (juice, smoothies) fill you up less than the same fruit eaten whole.
  • Pick healthy foods you enjoy and that are easy to make; a “perfect” food you won’t eat doesn’t help.
  • You don’t have to ban any of these. Just portion them on purpose.
SuperfoodWhy it can stall fat lossEasy swap or fix
NutsAbout 160–200 calories per small handfulPre-portion; count them into your day
Acai and other juicesAs much sugar as soda; doesn’t fill you upEat whole fruit
Steel-cut oatsSlow to cook, so they’re easy to skipRolled or quick oats
Brown riceNot much better than white for fat lossEat whichever rice you prefer, portioned
YogurtThin, sweetened yogurt isn’t very fillingPlain Greek yogurt, add fruit yourself
Dried fruitSugar concentrated into a few small bitesFresh fruit
GranolaBuilt to pack calories for hikingMeasure it; use as a topping
Olive oilAbout 120 calories per tablespoonMeasure instead of pouring
Almond butterAbout 100 calories per tablespoon; easy to overeatPre-portion; keep out of reach
SmoothiesLots of fruit, drunk quicklyEat the fruit; add protein if you blend

1. Nuts

Almonds, walnuts, cashews, pistachios: they’re all rich in fat. It’s mostly healthy fat, but fat has more than twice the calories per gram of carbs or protein (9 vs 4). A small handful is 160–200 calories, and salted nuts are very easy to keep eating. Enjoy them, but portion them out.

2. Acai juice

Acai sounds exotic, but orange juice, bottled “green” juices and smoothie drinks have the same problem: ounce for ounce, many carry as much sugar and as many calories as a regular soda.

Your body processes fruit sugar in juice much like any other sugar. Drinks also leave your stomach quickly, so you get hungry again sooner. Eat your fruit whole whenever you can.

3. Steel-cut oats

There’s nothing wrong with steel-cut oats nutritionally. They’re on the list because they break two of our core weight-loss rules: pick foods you enjoy, and pick foods that are easy. Steel-cut oats take around 30 minutes to cook, and plenty of people find them too chewy and bland to eat plain. If that’s you, rolled or quick oats are nearly identical nutritionally and far easier to stick with.

4. Brown rice

Brown rice is often called the healthier choice because it’s a whole grain with more fiber and minerals. That’s true, but brown rice also contains phytic acid, which reduces how much of those minerals you absorb, and most white rice in the US is enriched with iron and B vitamins.

For fat loss, the difference is small. Glycemic index doesn’t predict fullness well either: potatoes score high on it, yet they’re one of the most filling foods per calorie. (If you have diabetes, glycemic index matters more; talk to your doctor or dietitian.) Pick the rice you enjoy and watch the portion.

5. Yogurt

Dairy is a great source of protein and calcium, and many yogurts are fortified with vitamin D. The catch is that thin, sweetened yogurts are close to a drink, and liquids don’t keep you full for long. Choose plain Greek or Icelandic-style yogurt, which is thicker and much higher in protein, and add your own fruit.

6. Dried fruit

Take the water out of fruit and you concentrate its sugar into a small, easy-to-eat bite. A handful of raisins has about the same calories as two cups of grapes, but it won’t fill you up nearly as much.

Coach’s tip

Stick to fresh fruit. The water and fiber fill you up for fewer calories and help keep you hydrated.

7. Granola

Granola and trail mix were designed for hikers and campers: lots of calories in a small, light package. That’s perfect on a long hike and less helpful when you’re trying to eat less. Measure granola and use it as a topping, not a bowlful.

8. Olive oil

Olive oil is a kitchen staple for good reason: it’s rich in monounsaturated fat and antioxidants. But each tablespoon has about 120 calories, and a free pour on a salad or in a pan can easily be two or three tablespoons. Measure it.

9. Almond butter

Almond butter, like any nut butter, has about 100 calories per tablespoon, and it’s delicious enough that a jar can disappear in a few days. You don’t have to give it up. Measure a serving, then put the jar away.

10. Smoothies

Store-bought or homemade, fruit smoothies are full of sugar, go down fast and don’t keep you as full as eating the same fruit whole. If you like smoothies, make them a meal: add a scoop of protein, keep the fruit to one serving, and skip the juice base.

The bottom line

When fat loss is the goal, remember that a food being good for your health doesn’t mean it helps you lose weight. Plenty of other superfoods, like leafy greens, berries, beans and lean proteins, are a great fit for a fat-loss diet. And if you have a lot of weight to lose, losing it is one of the best things you can do for your health.

Frequently asked questions

Are superfoods bad for weight loss?

No, but many are calorie-dense or easy to overeat. Portion them deliberately.

Can I eat nuts while trying to lose weight?

Yes. Pre-portion a small handful and count it in your day.

Is brown rice better than white rice for weight loss?

Not by much. Portion size matters far more than which rice you choose.

Are smoothies good for weight loss?

Usually less than whole fruit. If you blend, add protein and keep the fruit to one serving.
