Nanako Ogino sniffs around any uneaten food on the plates at the staff restaurant of Tanita Corp.

She's not hungry and desperately scavenging for leftovers. She is, in fact, a 35-year-old registered nutritionist who works there, and the enjoyment of food and healthy eating is always on her mind.

As well as trying to work out why food has been neglected, she listens to the staff who eat at the canteen and jots down her findings in a log book. “We are getting less leftovers now after changing the ingredients and seasonings based on this information,” she says.

This week’s set menu consists of barbecued chicken, sauteed daikon radish and tuna, spinach seasoned with “nori” (dried laver) sauce, miso soup with "fu," a Japanese food made from wheat gluten, eggplant and green onion and rice. And the crucial cooking pointers are?

Just by removing the skin from the chicken, she says the calories fall by 80 kcal. Also the chicken is grilled in an oven toaster and no oil is used. A key to reduce salt content is the use of spices. Chili pepper, oregano and nutmeg will be used. The sourness of lemon juice is also key.

The side dish of sauteed daikon radish and tuna should have a crunchy texture. Don't make it mushy by overcooking. You may feel like adding a generous amount of flavorful tuna, but it is better to stick to the recipe by weighing it.

“Measuring is essential to reduce the calories,” Ogino says. The recipe books introducing lunches at Tanita list precise amounts such as “10 grams of fried fish cake” and “2 grams of dried seaweed” for two persons.

Some staff members who have been eating at the canteen told her that they had lost weight. An employee whose jawline was almost lost in fat saw it emerge to give his face a sharper edge.

“I lost five kilograms in six months myself when I started working here,” says Ogino with a smile. By eating out, one can easily consume 700 to 1,000 kcal per meal. But Tanita serves 500-kcal meals. The difference is not something to be taken lightly.

“When people’s eating habits change, their awareness seems to change also and they start to walk up the stairs when commuting, for instance. Although it may sound typical, I guess the keys to staying healthy are the small-step efforts in the daily meals and exercise,” says Ogino. Both serve two.
