How Many Calories in Acai? Nutrition Facts & Macros
100 grams of frozen unsweetened acai pulp has 58 calories
Protein 0.8g · Carbs 6.2g · Fat 3.9g
Acai is the fruit of a palm that grows in the Amazon floodplain, and what reaches the rest of the world is the frozen pulp — the thin purple layer scraped off a large stone. It is the rare fruit that gets most of its calories from fat: 3.94 g per 100 g against 6.21 g of carbohydrate, and just 58 kcal in total, because the pulp is 88.7 % water. Most of that fat is monounsaturated (2.01 g). The deep purple comes from anthocyanins, the same pigment family that colours blackberries and red cabbage.

Variations
Acai pulp (frozen, unsweetened)
58 calories per 100 g — the form this page describes, and the one sold as frozen packets. 3.94 g fat, 6.21 g carbohydrate, 2.55 g fibre, 0.8 g protein, and 88.7 % water. Tart rather than sweet on its own.
Acai bowl (with toppings)
The toppings decide the number, not the acai. A bowl built from one 100 g packet (58 kcal), a medium banana (105 kcal) and 40 g of granola (196 kcal) lands near 360 kcal before anything is drizzled on it. Honey, nut butter and a larger granola portion take it past 600. Weigh the granola if nothing else.
Acai pulp with added sugar
Most acai sold outside Brazil is sweetened, often with guaraná syrup and glucose — the Brazilian food table lists it as a separate food precisely because the two are not interchangeable. Sugar roughly doubles the calories and multiplies the carbohydrate. The figures on this page are for the unsweetened pulp; for a sweetened product, read its label.
Dietary Perspectives
For Weight Loss
At 58 kcal per 100 g, frozen unsweetened acai pulp is one of the lighter things you can build a breakfast on, and its 3.94 g of fat makes it more filling than the number suggests. The problem is never the acai — it is the bowl around it. Berries and a measured spoonful of seeds keep a homemade bowl under 150 kcal; granola at 489 kcal per 100 g and a drizzle of honey can quadruple it. Buy the unsweetened pulp and weigh the toppings.
For Athletic Performance
Acai is a recovery food rather than a fuel: 6.21 g of carbohydrate per 100 g will not power a session, and the 3.94 g of fat slows it further. Where it fits is a post-training bowl, blended with a banana for the carbohydrate and a scoop of protein for the repair. Its 6.16 mg of manganese per 100 g is genuinely high, and manganese is a cofactor in the enzyme that clears superoxide inside the mitochondria.
For Keto
One of the few fruits that fits keto comfortably: 3.66 g of net carbs per 100 g (6.21 g carbohydrate less 2.55 g fibre), with 3.94 g of fat to go with it. A whole frozen packet costs under 4 g. Build the bowl on coconut cream rather than milk, top with unsweetened coconut and a few berries, and leave out the granola, banana and honey — those, not the acai, are what put an acai bowl over a day's carb allowance.
Frequently Asked Questions
How many calories are in acai?
A 100 g packet of frozen unsweetened acai pulp has 58 calories (243 kJ): 3.94 g of fat, 6.21 g of carbohydrate of which 2.55 g is fibre, and 0.8 g of protein. Half a packet is 29 calories. What turns an acai bowl into a heavy meal is everything else in it — 40 g of granola alone adds about 196 calories, and a medium banana another 105.
What nutrients does acai have?
The unusual part is the fat: 3.94 g per 100 g in a fruit, of which 2.01 g is monounsaturated, 0.73 g saturated and 0.38 g polyunsaturated. Minerals are led by an exceptional 6.16 mg of manganese, then potassium (124 mg), calcium (35 mg), magnesium (17 mg) and phosphorus (16 mg). Iron is modest at 0.43 mg and sodium is negligible at 5 mg. The purple colour is anthocyanin, a polyphenol pigment.
Is acai actually a superfood?
It is genuinely nutrient-dense for a fruit, and its fat and manganese content are unlike anything else in the fruit aisle. But the marketing around it — weight loss, detox, disease prevention — runs far ahead of the evidence, and the antioxidant scores quoted in advertising are laboratory measurements that do not translate into effects in the body. Treat it as a good fruit with an interesting profile, not as a treatment.
What's the best way to eat acai?
Frozen unsweetened pulp blended into a bowl or smoothie is the standard use — it is too tart to eat on its own, which is why it is nearly always sweetened somewhere. Blend it with a little liquid and, if you want it sweet, a banana rather than syrup. Keep the granola to a measured spoonful: at 489 kcal per 100 g it outweighs the acai several times over. Ready-made bowls from a cafe are usually the sweetened kind.
Acai vs blueberries — which is better?
For energy they are almost identical, 58 kcal against 57 per 100 g. Acai gives you fat (3.94 g against 0.33 g) and far fewer carbs (6.21 g against 14.49 g); blueberries give you more of what most people are after in a berry — and they cost a fraction as much and keep in the fridge. Acai's advantage is its macro shape, not a nutritional gulf.
Is acai keto-friendly?
Yes, unusually so for a fruit: 6.21 g of carbohydrate minus 2.55 g of fibre leaves 3.66 g of net carbs per 100 g, and the 3.94 g of fat works with a ketogenic diet rather than against it. A whole 100 g packet costs under 4 g of net carbs. What breaks it is the rest of the bowl — granola, banana and honey are what push an acai bowl out of keto range, not the acai.

per 100g
Per 100 g, frozen acai pulp has 58 kcal — almost the same as blueberries (57 kcal) — but the two get there differently. Blueberries carry 14.49 g of carbohydrate and almost no fat; acai carries 6.21 g of carbohydrate and 3.94 g of fat. With 2.55 g of fibre that leaves 3.66 g of net carbs, less than a third of what blueberries bring. The fruit it most resembles nutritionally is avocado, the other fat-dominant one.
