CORE Nutrition mathematics, solved by optimisation

Your meal plan, solved by optimisation algorithms.

Every macronutrient and micronutrient is balanced to your needs by a hybrid of optimisation algorithms, against the RDA, AI and UL standards. The mathematics of nutrition science becomes a plan you can actually cook, for your medical conditions and your local cuisine.

The core of Synergy Diet

Nutrition mathematics, turned into a plan by optimisation algorithms

Your nutritional targets are set from the international reference standards: RDA (Recommended Dietary Allowance), AI (Adequate Intake) and UL (Tolerable Upper Intake Level). Then a hybrid of optimisation algorithms searches for the combination of real meals that meets every target at once, while keeping the upper limits in check. For every problem, the best-suited algorithm is selected automatically.

Parameters adapt to you: energy follows your calculated needs, targets adjust for your medical conditions, and the weight of each target depends on how critical it is.

How it works

From your profile to a ready plan in four steps

No spreadsheets, no guesswork. Tell us about yourself once and let the system do the heavy lifting.

1

Build your profile

Age, height, weight, activity, goal and country. Add medical conditions, medications and foods you dislike.

2

Describe what you want

Ask in plain language, for example "2000 kcal, no rice at dinner, quick meals". Our AI understands the request.

3

We engineer your plan

An optimisation engine builds the menu, balances every macro, then clinical and cultural agents refine it.

4

Eat, tweak, repeat

Open your plan, swap any meal, chat with the AI assistant and adapt plans for family members.

Features

Everything a modern nutrition plan needs

Built for people with real constraints: health conditions, budgets, cultures and busy lives.

Clinically aware planning

Pick up to three conditions and the system merges their dietary rules into one safe set of limits and forbidden foods.

  • 27 condition profiles from diabetes to celiac disease
  • Medication-aware food restrictions
  • Clinical strategy notes written for your plan
  • Programme overseen by a nutrition specialist

Numbers you can follow

Solvers and a final balancing step optimise your calories and macros toward your targets, and every item comes with an exact portion weight.

  • Portion weights in grams for every item
  • Nutrition tables with vitamins and minerals
  • Built-in variety logic across days

Built around your country

Your country shapes everything: the language of your plan, the units, the start of the week, the payment options and the food culture it draws on.

Swap any meal

Don't fancy a dish? Pick from up to five alternatives with similar calories and macros. Swapping is free.

AI nutrition assistant

Chat about your plan, ingredients or habits with a built-in assistant that can see your plan. Usage is charged in coins.

Family simulation

Adapt your plan to a family member's calorie target so everyone can share similar meals. Uses a few coins.

Installable web app

Add it to your home screen on Android, iOS or desktop and open it like a native app.

Fair, safe billing

Coins are deducted only after your plan has been generated. If generation fails, nothing is deducted.

Meal patterns

Pick the rhythm that fits your day

Synergy Diet comes with 11 ready-made meal patterns, from a 9-meal schedule to Ramadan and time-restricted fasting. Your calories are split across the meals automatically.

The Synergy Diet programme runs under the supervision of a nutrition specialist. It is still a planning tool, not medical advice, so talk to your healthcare professional before changing your diet. See our Terms.

FAQ

Questions, answered

No. The Synergy Diet programme is overseen by a nutrition specialist and applies built-in dietary rules for common conditions. It is still a planning tool and does not provide medical advice, diagnosis or treatment. Always consult your healthcare provider before making significant changes to your diet, especially if you are pregnant, take medication or have a medical condition.

Most apps pick meals from a fixed list. We use a hybrid of optimisation algorithms that balances your macronutrients and micronutrients against RDA, AI and UL standards, with AI helping to understand your request and health profile, then localise the result to your country's food culture.

Synergy Diet supports 139 countries and 68 languages. Your plan is translated and adapted to local foods, units and calendar conventions based on the country you choose.

Coins are deducted only after your personalised plan has been generated. If an error occurs before that, nothing is deducted. You are billed for the days actually delivered.

Not yet. Web (email) and Telegram accounts are separate today, so coins and plans do not carry over between them. Choose the platform you prefer and sign in there.

Press "Get started", sign up with your email, confirm the 6-digit code we send you, then complete your profile and request your first plan.
