What the app does

02 Portions

Your amount, not the standard amount.

Every recipe is written for a standard portion. KernBite scales it up or down to your requirement using a portion factor. Nutritional values and shopping quantities grow with it.

Eight nutrition profiles determine how the calories are divided between protein, carbohydrates and fat. Allergens and intolerances rule out the affected recipes entirely. For ingredients you merely dislike there is the milder option: replace, leave out, or reduce the amount.

Gratinierte Nudeln520 kcal, 36 g protein. Lunch, ready in 30 minutes. AI

04 Household and groups

Two adults are not twice the amount.

Anyone who does not eat alone sets up a household. KernBite adds the actual daily requirements together and cooks accordingly. The source code carries the example: 2159 kilocalories and 1600 kilocalories give a quantity factor of 1.74 instead of 2.0.

Everyone in the household swipes the same recipes. The shared cookbook then shows what everybody likes and what only some do. Anyone who wants to compete sets up a challenge and enters weight, training, steps and wellbeing. There are no prizes and no entry fees.

06 Fussy eating

Someone who dislikes onions does not need a recipe of their own.

Allergies and intolerances exclude a recipe entirely. For everything someone simply does not like there is the milder step: replace it, leave it out or halve the amount. The ingredient stays in the recipe, struck through, with the replacement next to it.

This applies per person and not per household. Which ingredient is meant is decided on the server: broccoli and broccoli florets are the same thing, no matter how the recipe writes it.

Challenge

Together it is easier

Resolutions rarely hold on their own. In KernBite you set up a group, share a six-digit code, and whoever has it joins in. After that half a minute a day is enough: check in, done.

You decide what it is about

A challenge has a name, a period and the goals you pick. Steps, training, weight, calories, protein, wellbeing. Anyone who does not want to talk about weight leaves it out of the scoring.

Points per category

Every category is scored on its own, and there is an overall score for the group. That way the same person does not always win, and whoever trails on weight can lead on steps.

Steps come from the watch

Anyone using a Garmin or Health Connect pulls the steps in with one tap instead of typing them. Without a watch you enter them by hand, which counts just the same.

You decide what becomes visible

Under „What I share“ you hide individual values from the group. Your weight then stays your business, while steps and training keep counting. Nothing is preset that you have not released yourself.

One note we consider more important than any promise: values that were visible to the group during a running challenge cannot be taken back out of anyone's head afterwards. On the server they are deleted along with your account; with the other members they were visible beforehand. So think first about what you release.

The calculation

Calculated openly, without a language model.

Your daily target comes about in four steps. Each of them is a fixed formula, not an estimate and not a recommendation out of a cloud.

No language model takes part in the calculation. The same inputs always give the same result.

The app does not flatter. If the result comes out very low, or the pace is too fast, a clear warning appears instead of quietly nudging the number upwards.

  1. 01Basal metabolic rateIf an InBody scan is available, the measured value counts. Otherwise the app calculates by Mifflin-St Jeor from age, height, weight and sex.
  2. 02Everyday lifeTimes an activity factor, depending on how much you move outside of sport.
  3. 03SportEntered as calories per week and spread evenly over seven days.
  4. That gives the maintenance requirement.
  5. 04DeficitFor weight loss the app calculates with 7,000 calories per kilogram of body fat, spread over the chosen period.
  6. That gives your daily target.

Fibre and omega-3

Both appear on every recipe, and both are looked up rather than made up. The sources are listed here so nobody mistakes them for a house opinion.

Fibre. The German Nutrition Society gives a guideline of at least 30 grams a day, and alongside it a density of 14.6 grams per 1,000 calories. The app takes the larger of the two. Eat 3,000 calories and that comes to around 44 grams instead of 30. The fixed value alone would short-change anyone with a high turnover.

Omega-3 is listed separately: ALA and EPA/DHA. The total misleads. A chia pudding carries 8.1 grams of omega-3 and none of it covers the need for EPA and DHA; the body converts ALA only in the low single-digit percentage range. For ALA the German Nutrition Society sets 0.5 percent of energy, around 1.7 grams at 3,000 calories. For EPA and DHA it gives no value for adults outside pregnancy and breastfeeding; the app uses the EFSA figure of 250 milligrams.

Per recipe the split comes from the ingredients. How much of an ingredient's omega-3 is EPA and DHA comes from the USDA nutrient database. Per food, not per product group: mackerel 100 percent, salmon 93, catfish 58, beef 0. Plants contain no EPA and no DHA, and that is not an assumption.

Weekly kitchen

The weekly kitchen is a second mode of the weekly plan. It does not count in finished portions but in bases: intermediate stages such as a minced-meat base, cooked rice or a tomato sauce, from which different dishes are built in the evening. The same minced-meat base becomes bolognese on Monday, chili on Tuesday and shepherd's pie on Wednesday.

Mise en place is what a restaurant kitchen calls it: everything chopped, cooked and portioned before the cooking starts. The app turns that into a work plan for the preparation day, with order, amounts, containers and shelf life, and ticks off what is done. In the recipe every step carries whether it belongs to the preparation day or to the evening.

What can be done ahead is written in the preparation steps themselves. Measured across 686 main meals in the stock: 67 percent of the work steps, that is peeling, chopping, cooking and simmering, can be moved to a preparation day. What remains in the evening is a median of 10 minutes at the stove, almost all of it hands-on. Lunch is the previous evening's dish, reheated, and costs not a minute of work.

The time limits are set by the German Federal Institute for Risk Assessment, not by the app. Cooked items such as sauce, stock, rice or meat keep for 3 days in the fridge, boiled potatoes 3 to 5, raw cut produce one day. A cooked base therefore serves only days 1 to 3; everything after that comes from the freezer, and the plan enters the thawing as a step on the day before. In the freezer, blanched vegetables keep for 6 to 12 months according to the BZfE, lean minced meat for 1 to 3 months.

Lighter at lunch is a preference in the settings and means easy on the stomach, not low in calories. Every dish gets a score from fat, cooking method, heavy ingredients such as cream and breading, carbohydrate load and portion size; light is anything with at most one point. A breaded goat's cheese salad at 400 calories is heavy, a chicken skewer with rice at 490 calories is light. A calorie filter sorts a quarter of the cases wrongly, so there is none.

Variety is up to you, not the planner. The setting "How often do you want to cook?" with 1 to 7 different dishes a week remains the only dial for it. At 1 the app plans one dish from one base, every day, and offers the variation without forcing it. Only above that does the planner make sure the dishes differ in cuisine, category and cooking method.

Who is behind it

Behind KernBite stands a private individual, Jose Daniel Encarnacao from Ketsch, who runs the project alongside a job. The app, the recipes and the calculations are protected by copyright; third-party components in use are subject to their own terms.

That has a flip side, and it should be stated openly here. Operation depends on one person's spare time. There is no hotline and no guaranteed availability. Questions go to kontakt@kernbite.de and are answered as soon as time allows.

Worth knowing

  • From the age of 16. Between 16 and 18 only with the consent of a parent or guardian.
  • It keeps running without a network. Entries stay on the device and go to the server as soon as there is a connection again.
  • Visible to others are the user name, group membership and the values shared in a challenge. Within a household, members additionally see each other's likes and dislikes.
  • No claim to permanence. Recipes may be added and may fall away; a particular set of features is not guaranteed.

Health notice

KernBite is not a medical device. Nutritional values are averages and vary with the product and the preparation; the calculation replaces neither a medical assessment nor dietary counselling. With pre-existing conditions, during pregnancy and breastfeeding, or after an eating disorder, professional advice comes before the app.
