Powdered complete food is a food that, mixed with water, provides in a single serving what a balanced meal should contain: energy, protein, carbohydrates, fat, fibre and a broad range of vitamins and minerals. In the European Union it is sold as a conventional food. It is neither a supplement nor a weight-loss product, and it works best as one more meal within a varied diet.

In this guide we explain where it comes from, how it differs from other powdered products, what EU rules say and what to check on the label to tell a good one from a mediocre one.

What powdered complete food is

A complete food is a food formulated to cover a whole meal on its own. The idea was born in the United States around 2013, when the first powdered formulas designed to eat well without cooking appeared. Within a few years it spread to Europe with brands such as Huel in the United Kingdom and Satislent in Spain, and today it is a category that attracts major food groups: we covered it in our article on Danone's acquisition of Huel.

In practice, a complete food is usually a blend of powdered ingredients (cereals, pulses or plant proteins, fats, fibre) with added vitamins and minerals to complete the profile. It is made with water in a shaker in under a minute and is meant for the moments when you would otherwise eat badly or not at all: lunch at the office, a trip or a day with no time.

How it differs from other powdered products

Products that look alike on the shelf have different purposes and rules:

Product	What it is for	Energy per serving	Main regulation
Protein shake	Adding protein to the diet, usually around exercise	Variable, not meant to be a meal	General food rules
Complete food	Replacing a meal with a balanced one	Similar to a meal (402 kcal in Satislent Food)	General food rules, labelling and added vitamins
Meal replacement for weight control	Replacing meals within a low-calorie diet	Between 200 and 250 kcal per meal	Conditions in Regulation (EU) 432/2012
Total diet replacement for weight control	Replacing the whole day's diet for a period	The whole day's energy	Regulation (EU) 609/2013 and Delegated Regulation (EU) 2017/1798

The key difference from a protein shake is balance: the shake provides mainly protein, while a complete food contains carbohydrates, fat, fibre and micronutrients in meal proportions. The difference from weight-loss replacements lies in energy and purpose: those are designed for low-calorie diets and have their own legal requirements.

How complete food is regulated in the EU

EU law has no specific category called "complete food", so it is worth distinguishing which rules apply to each type of product.

Conventional food

A complete food such as Satislent Food is marketed as a conventional food, subject to the same rules as any other food:

General food law (Regulation (EC) 178/2002): safety, traceability and manufacturer responsibility.
Labelling (Regulation (EU) 1169/2011): ingredients listed by weight, highlighted allergens and a nutrition table.
Added vitamins and minerals (Regulation (EC) 1925/2006): only those listed in its annexes, in authorised chemical forms and in a significant amount can be added. According to the Spanish food safety agency (AESAN), there are still no harmonised maximum amounts in the EU.
Nutrition and health claims (Regulation (EC) 1924/2006 and Regulation (EU) 432/2012): a brand can only attribute to its product the effects authorised by the EU, with the set wording and conditions.

Weight-control replacements

Weight-loss products have their own, stricter rules:

Meal replacement for weight control. To claim that replacing one or two meals a day helps maintain or lose weight within a low-calorie diet, the product must provide between 200 and 250 kcal per meal, get 25% to 50% of its energy from protein and provide at least 30% of the reference values for vitamins and minerals, among other requirements (Regulation (EU) 432/2012, as amended by 2016/1413).
Total diet replacement for weight control. It is intended for overweight or obese adults who want to lose weight and replaces the whole day's diet. Its composition is regulated in detail by Delegated Regulation (EU) 2017/1798.

A complete food with around 400 kcal per meal does not meet the conditions of a weight-control replacement and cannot be presented as a weight-loss product. If you see a complete food advertised that way, be wary.

What a good powdered complete food should contain

These are the points that separate a good complete food from a shake with added vitamins. The guide figures are based on European reference values for an adult.

Meal-sized energy. The EU label reference is 2,000 kcal a day. Split across three or four meals, a main meal is around 400-600 kcal. Below that figure, the product works more as a snack.
Enough protein. The EFSA recommends 0.83 g of protein per kilo of body weight a day for adults, about 58 g for a 70 kg person. A meal providing 20 g or more makes a good contribution. Look at the source too: several plant proteins combined (pea, rice, hemp) give a more complete profile than a single one.
Real fibre. The EFSA considers 25 g of fibre a day adequate, so a meal should provide around a third, about 8 g. It is one of the nutrients most lacking in the Spanish diet, as we explain in our guide on how much fibre you need.
Little sugar. Check the "of which sugars" line. In a balanced meal, carbohydrates should come mainly from cereals and pulses, not added sugar.
Good-quality fats. Ideally from sources such as olive oil or seeds, and low in saturates (the EU reference is 20 g of saturates a day).
Moderate salt. The EU reference is 6 g a day. A single meal should not take a disproportionate share.
Vitamins and minerals. The EU label has reference values for 13 vitamins and 14 minerals. A good bar is the one the EU sets for meal replacements: at least 30% of each reference value per meal. If you want to know what each one does, we cover them in the 26 essential micronutrients.
Recognisable ingredients. The list is ordered by weight: the first ingredients tell you what the product is really made of. If it starts with oats, pulses or olive oil, you are on the right track; if it starts with maltodextrin or sugar, its base is refined carbohydrates.

How to read the label and compare brands

Comparing complete foods is easier if you always follow the same order:

Calculate per meal, not per 100 g. Each brand defines a different serving (90 g, 100 g, two scoops…). Convert everything to "one meal" before comparing.
Energy and protein per meal. Check that it is a real meal and how much protein it provides.
Fibre, sugars and salt. These three figures do the most to separate a carefully made formula from one that is not.
Percentages. The % NRV (nutrient reference value) only exists for vitamins and minerals. Energy, fat, sugars, protein and salt use % RI (reference intake). For fibre, EU law sets no reference value at all, so a fibre percentage on a label does not follow any official reference.
The ingredient list, starting with the first three, and the allergens, which must be highlighted. If you have coeliac disease or gluten intolerance, check whether it contains oats or wheat.
Sweeteners and additives. They are not a problem in themselves if authorised, but it is worth knowing what you are having and whether it agrees with you.
Price per meal. Divide the price of the bag by the number of meals it makes.

As an example, this is the per-meal table (100 g) for Satislent Food:

Per meal (100 g)	Satislent Food
Energy	402 kcal
Protein	30 g
Carbohydrates	44 g, of which sugars 4 g
Fat	10 g, of which saturates 1.5 g
Fibre	7.7 g
Salt	1.0 g

Its first ingredients are oats, Canarian gofio and powdered extra virgin olive oil, and it contains pea, rice and hemp proteins. It contains gluten (oats). If you want to see how it compares with a specific brand, in Huel vs Satislent we go through the differences in ingredients, price and taste, and in the comparison with Plenny Shake and yfood you can see the price per meal of three brands widely sold in Spain.

Who powdered complete food makes sense for

It makes sense if:

You often eat out or at the office and tend to end up with a sandwich or fast food. A complete food is a balanced alternative in a minute (more ideas in how to eat healthily at work without cooking).
You have days with an impossible schedule and tend to skip meals.
You travel or play sport and need a practical, easy-to-carry meal.
You want to control what you eat in one or two meals without weighing and cooking.

Check first, or it is not for you, if:

You are looking for a weight-loss product: as we have seen, a complete food is neither designed nor authorised for that.
You are pregnant, breastfeeding or it is for a child: adult formulas use adult reference values.
You have a condition that requires a specific diet (kidney, digestive, metabolic) or coeliac disease, if the product contains gluten.
You are taking GLP-1 medicines, which change appetite and digestion. Our guide on what to eat on Ozempic covers this.
You want to replace all your meals permanently. A variety of fresh foods remains the basis of a good diet; a complete food works best as one of your meals of the day.

If it fits your routine, you can start with one meal a day. Satislent Food is the complete food we make in Spain with oats, Canarian gofio and olive oil.

Frequently asked questions

Can you live on powdered complete food alone?

Some formulas provide the reference nutrients for a whole day, but that is not how we recommend using it. The sensible approach is to use it for one or two meals and keep fresh foods for the rest: fruit, vegetables, pulses, fish or whatever is part of your usual diet.

Does complete food help you lose weight?

It is not designed for that. In the EU, products advertised for losing or maintaining weight by replacing meals must provide 200 to 250 kcal per meal and meet other requirements. A complete food provides the energy of a normal meal. What happens to your weight depends on your overall diet and activity.

Is it the same as a protein shake?

No. A protein shake mainly provides protein to complement your diet. A complete food also provides carbohydrates, fat, fibre, vitamins and minerals in meal proportions.

Why is it called "complete food" in Spain too?

It is the international name for the category and the one many brands use, including Spanish ones. In Spanish people also say "comida completa"; both terms mean the same thing.

How many vitamins and minerals should it contain?

The EU label has reference values for 13 vitamins and 14 minerals. A good complete food covers the vast majority, and as a practical bar you can use the one the EU sets for meal replacements: at least 30% of each reference value per meal.
