Diet Startup ‘DayTwo’ Creates Unique Personalized Diets By Checking Your… Gut Bacteria

High blood sugar level is a risk factor for many complications, such as type II diabetes, heart disease, and stroke. That’s why doctors recommend we control our blood sugar levels by keeping a healthy, low-sugar diet.

But DayTwo, an Israeli startup spun off the Weizmann Institute, suggests that people have different responses to food. As it turns out, ice cream is less harmful to some people than others, and so are many other foods.

It all depends on the different microbes we have in our guts. By studying and analyzing your individual gut microbiome – the vast collection of bacteria that you host – DayTwo claims it can translate your unique gut bacteria into a personalized diet, potentially preventing diabetes and heart disease. The startup provides a cutting-edge test and app for a one-time fee of $500.

DayTwo‘s product is based on research (published in the sceintific journal Cell) conducted by Prof. Eran Segal and Dr. Eran Elinav of Israel’s Weizmann Institute of Science; the research technology was licensed to DayTwo.

According to the researchers, some people respond to so-called healthy diets, while others don’t. They claim that bacteria in our intestinal tract vary among individuals, and therefore people digest food differently.

Your gut microbiome is the collection of all microbes that exist in your digestive tract and help you digest food. In our gut alone, we have about 100 trillion microbes, similar to the number of cells that we have in our entire body. Your microbiome is unique to you, and influences the way your body reacts to different foods.


“The huge differences that we found in the rise of blood sugar levels among different people who consumed identical meals highlights why personalized eating choices are more likely to help people stay healthy than universal dietary advice,” Segal said in a statement.

Founded in 2015 by CEO Lihi Segal and Yuval Ofek, DayTwo is the brainchild of Segal and Elinav. The startup has already received funding from billionaire Marius Nacht, the co-founder of successful Israeli cyber-security firm Check Point. His investment is estimated at a couple of million dollars.

“Foods that are perceived as healthy for everyone are not recommended for some people”

How does DayTwo work? First, you provide a stool sample, through a kit sent by DayTwo, along with your most up-to-date blood test results. DayTwo sequences the DNA of your gut microbes, the micro-organisms that help us digest.

Then, DayTwo’s technology predicts which foods are good for you. Analyzed by a patent-pending algorithm, the technology provides a unique nutritional profile designed just for you. The startup’s scoring system rates thousands of different foods and food combinations based on your gut microbiome analysis and lifestyle factors.


Then, you receive a nutritional report through a personalized nutrition app. The report provides you with specific food recommendations for normalizing blood sugar levels throughout the day and night. It generates food recommendations specific to your gut makeup, for breakfast, lunch and dinner. The app also analyzes your daily eating routines and recommends healthy snacks.

According to CEO Lihi Segal, “our food recommendations are based on matching thousands of foods to the individual’s profile. The findings are very surprising: Foods that are perceived as healthy for everyone, such as rice, are not recommended for some people. In some cases, it turns out that foods like ice cream are not harmful.”
