Protein first is how you keep muscle while you lose fat

Protein firstThe Eighty Thirty app works out your daily protein target and counts the protein on every plate you log. Calories, carbs, sugar, fibre and fat are counted alongside.

Asian or Western, it counts itHawker plates, home cooking, restaurant meals and packaged food, from any cuisine.
Get it right once, use it foreverBuild a recipe or save a meal once the numbers are right, then log it again in one tap. Your figures stay the same day after day.
Food, training and weight in one placeLog a strength session in one tap and chart your weight next to your food.

The strongest version of you is already in there

It runs on protein, and many of us get less than we think. Feed it properly and you feel the difference in weeks. Eighty Thirty makes that the easiest habit of your day.

This is what a high-protein plate looks like

Five everyday meals and the protein on each. Hit ~30 g at each of your three meals and you are more or less covered for the day.

Seafood pasta57 g protein
Chirashi bowl50 g protein
Teriyaki bowl with onsen egg43 g protein
Five-egg-white omelette with toast28 g protein
Teppanyaki beef40 g protein

Protein builds the muscle, and strength training makes it stay

Lift a few times a week and your body keeps the muscle it has, grows more, and holds up the bone underneath. Eighty Thirty tracks the protein and logs the training, side by side.

This is what Eighty Thirty tracks, and why

ProteinMuscle is rebuilt from protein and from nothing else. Eighty Thirty counts it on every plate.
CaloriesCalories decide whether the fat comes off or goes on, whatever else you get right.
CarbsCarbs are the fuel your training runs on. Cut them too hard and you feel it in the gym first.
SugarSugar reaches your blood within minutes, and while insulin is high you are storing, not burning.
FibreFibre feeds the gut, slows the sugar down and keeps you full. Most of us are well under the 25 g a day the WHO recommends.
FatFat carries the vitamins your body cannot absorb on its own, so the aim is the right amount, not the least.
SodiumMost people eat about twice the daily limit without noticing. Eighty Thirty watches it against a ceiling.
WeightLog your weight, and your muscle and fat mass if you have a body scan, and see what your weight loss is made of.

Getting started takes one photo

Take a picture of your plate and the protein is counted. Log a strength session in one tap. Watch your streak build.

Frequently asked questions

What does the Eighty Thirty app do?

Eighty Thirty is a macro tracker that focuses on protein to help you keep your muscle while you lose fat. It counts the protein on every plate from a photo, a typed meal or a barcode, and tracks your calories, carbs, sugar, fibre and fat alongside it.

How much protein do I need a day?

It depends on your weight, how active you are and your goal. Our free macro calculator works it out for you, with your resting rate and maintenance calories. Hit about 30 g at each of your three meals and you are more or less covered.

How do I lose weight and keep it off?

Keep your muscle while you lose fat. Eat a little under your maintenance calories, get enough protein at every meal and lift weights a few times a week, so what comes off is fat and the muscle that keeps you strong stays. Eighty Thirty tracks all three in one place.

I do a lot of cardio but can't lose weight. Why?

Cardio burns calories, but what you eat decides whether the fat comes off. If the food quietly makes up the difference, the scale will not move. Keep the cardio if you enjoy it, check your calories and protein, and add strength training so you keep your muscle while the fat goes.

Where do I start if I want to lose fat?

Start with your numbers. Our free macro calculator works out your maintenance calories and your protein target. Then aim for about 30 g of protein at each meal, lift a few times a week, and log what you eat so you can see what is working.

Where do I sign up?

Join the waitlist at eightythirty.com/join and you will get an email the day the app opens. Eighty Thirty launches on the App Store and Google Play, and the same link will take you there.

Do I pay when I sign up?

No. Your first seven days are free and we do not ask for a card to start. If you want to carry on after that, you choose a plan on the website.

What do I get for it?

Your protein counted on every plate, a streak of the days you hit it, and a log of your strength sessions. Your calories, fat, carbs (with the sugar and fibre inside them) and sodium are tracked alongside, so you can see what is helping and what is holding you back.

How do I log my food?

There are five ways, and you can mix them through the day.

  • Photo scan. Take a picture of your plate and the app works out what is on it and counts the protein.
  • AI estimate. Type what you ate in your own words and the app estimates it for you.
  • Barcode scan. Scan anything packaged and the app pulls up that product's figures.
  • Manual entry. Key in the figures yourself, straight from a label or a recipe.
  • Add from Library. Log a meal you have saved before in one tap.

Whichever you use, the app counts the protein and, where the data exists, the calories, fat, carbs (with the sugar and fibre inside them) and sodium. Tap once to log a strength session and the Home screen shows where you stand.

What happens to my data when the free week ends?

We keep your meals, your library and your figures for 90 days after your free week or your plan ends, so you can take a break and pick up where you left off. We email you before that time runs out, and if you have not chosen a plan by day 90, we delete your data.

Can I delete my profile?

Yes, any time, from inside the app. Everything you logged goes with it.

Does it work for the food I actually eat?

Yes. It reads home cooking, restaurant and hawker plates, packaged food and the brands you buy, from any cuisine: Asian, Western, Japanese and more.

Do I have to count calories?

No. The app counts everything for you, calories included, from the photo, the typed meal or the barcode. Protein is the number you watch; the rest is tracked so you can see when too much sugar or sodium, or too many calories, is holding your progress back.

Is there a community?

Yes. Follow Eighty Thirty on Facebook, Instagram, Threads, X, YouTube and TikTok for strength training tips, high-protein meal ideas and encouragement.
