About this app

THE DIET SCIENCE

Nutrition. Lifestyle. Understanding.

What if tracking could help you understand more than just the numbers?

Created in Australia, The Diet Science brings nutrition, lifestyle and intelligent technology together to help you track what matters, recognise your patterns and make more informed everyday choices.

From what you eat to how you move, sleep and hydrate, see the bigger picture of your everyday lifestyle.

Don’t just track it. Understand it.

SNAP IT. SAY IT. LOG IT.

Logging your food should be simple.

Snap a photo of your meal and Diet Science does the logging for you, identifying your food and estimating its nutrition so you can quickly see what’s on your plate.

Prefer to talk? Simply say what you ate.

Or search and log your food yourself.

Track calories, protein, carbohydrates, fats, fibre and other nutrients without turning every meal into a calculation.

Snap it. Say it. Log it. Done.

MORE THAN FOOD TRACKING

Bring the different parts of your lifestyle together:

* Food, calories, macros and nutrients
* Steps and physical activity
* Sleep
* Water and hydration
* Weight and progress
* Nutrition and lifestyle goals
* Daily and weekly trends
* Compatible health and fitness integrations
* Recipes, meal ideas and food alternatives

One meal is one moment. One day’s activity is one moment. One night’s sleep is one moment.

Over time, the patterns tell you more.

SAY HELLO TO DS, YOUR AI NUTRITION COACH

You’ve tracked it. Now DS helps you understand it.

Ask DS about your meals, nutrition, goals and progress.

“Hey DS, how was my protein this week?”
“What could make my breakfast more balanced?”
“Am I getting enough fibre?”
“What patterns can you see in the way I’ve been eating?”

DS helps you explore your nutrition, recognise patterns and turn everyday tracking into simple, practical insights.

Because knowing what you ate is useful.

Understanding what you can learn from it is even better.

MORE THAN CALORIE COUNTING

Calories matter, but they don’t tell the whole story.

Diet Science helps you look beyond calories at the nutritional balance of your food and how it fits alongside your activity, sleep, hydration and progress.

Because nutrition isn’t simply about counting more or eating less.

It’s about understanding what you’re giving your body.

LEARN WITH DIET SCIENCE

Why does protein matter? What does fibre actually do? How does metabolism work? Why can nutrition needs change throughout life?

Don’t just follow nutrition advice. Understand the science behind it.

Explore evidence-informed articles, videos and simple explainers from Puja Matharu and the Diet Science nutrition team, making nutrition science easier to understand and practical for everyday life.

AI WHEN YOU WANT IT. HUMAN EXPERTISE WHEN YOU NEED IT.

Use DS for everyday nutrition insights and, where available, connect with a nutrition professional for personalised support.

Choose to share relevant nutrition information, goals and progress with your nutrition professional, helping create a more connected and informed experience.

BUILT FOR REAL LIFE

Food is personal. Lifestyle is personal. And no two journeys look exactly the same.

Created in Australia with a background in nutrition, health education, technology and machine learning, Diet Science is designed for diverse foods, cultures and lifestyles around the world.

Our belief is simple:

Better choices begin with better understanding.

THE DIET SCIENCE

Track. Recognise. Understand. Learn.

Don’t just track it. Understand it.

The Diet Science is a nutrition and wellbeing app. It is not a medical device. It does not diagnose, treat, cure or prevent any medical condition, and it is not a substitute for advice from your doctor or an accredited practising dietitian.
Track food and lifestyle with ease. Snap or say your meals, meet DS
