Can you lose weight without giving up hawker food?


SINGAPORE – Would someone trying to lose weight eat nasi lemak with fried chicken, egg prata with curry and economy rice regularly? Tan Chin Hock did. Nor did he give up McDonald’s breakfasts, pasta or biscuits.

Yet in two months, the 47-year-old says he lost 3.2kg and trimmed 3.8cm off his waistline. How did he do it without exercising excessively, doing meal prep or giving up his favourite hawker dishes?

By tracking everything he ate and making sure he burned more calories than he consumed, he says.

From June 1 to July 31, the 1.68m-tall founder of health coaching app LeanerTogether used its nutrition-tracking feature to slim down from 64kg to 60.8kg. His waist shrank from 32 inches (81.3cm) to 30.5 inches (77.5cm).

An InBody scan on July 31 measured his body fat at 11.9 per cent, down from 22 per cent when he embarked on his weight-loss plan two months back.

“I feel very good about where I am today. I am at the leanest in my adult life, even leaner than when I was serving as a commando during national service. I feel strong, energetic and in control of my health,” says the father of three.

Tan, who works as an assistant manager in a hospital, began building LeanerTogether with agentic coding assistant Claude Code on June 1 as a side hustle.

Claude Code came up with a working web version by the end of the day. For starters, he made sure his app scanner was able to detect well-loved local dishes like chicken rice and laksa, which are in LeanerTogether’s database. These dishes are staples for most working adults here, who do not have the luxury of time or energy to cook their own meals, he says.

He used AI to search for publicly available nutrition information and standard recipes, then structured the data into individual local dishes with estimated portions, protein, carbohydrates and fats.

Tan, who has a bachelor’s degree in business administration from RMIT University, which he obtained at Singapore Institute of Management, decided to test the app on himself while refining it.

He got inspired after competing in the Natural Elite Championship 2025, organised by the World Natural Bodybuilding Federation’s Singapore chapter. He trained an hour three times a week in the gym in the nine months leading up to it.

He also went on a three-month diet before the contest held in August 2025, but was not successful, as he says he was unaware of the calorie count of some foods. For example, he mistook coleslaw as a healthy choice but later found out it was high in calories due to the use of mayonnaise.

He placed fourth among five contestants in his category of Men’s Fit Model (First Timer) below 174cm. The experience spurred him to turn what he had learnt about balancing calorie intake and output into an everyday tool for people just like him, who eat out regularly.
