"What we thought was really going to help people was to pare that back and make it as simple as possible. The actual truth is when you boil it all down, weight loss can be simple."
The secret, she says, is making it convenient, which is what Fresh Start aims to do.
"Everyone knows what they should be doing to lose weight. But it's having the tools and putting it into practice that counts."
Fresh Start allows users to choose from one of three plans, ranging from 1200 calories a day to 1800 calories a day, depending on their level of daily activity. You can also choose between a 10-meal plan (providing five dinners for two people) or a 20-meal plan (providing five days of dinner and lunch for two people).
"When I was working as a dietician, lunch was a major pain point," Lim says. "If you're serious about losing weight, you have to do dinners properly and think about lunch as well."
Priced from $159.99 per week, the range features more vegetables and lean proteins than other My Food Bag offerings and lower levels of carbohydrates. It also excludes all refined sugar.
The website also includes tips on how to get moving and recipes for healthier meals and snack options.
The Fresh Start range is the latest in the My Food Bag empire, founded by Lim and entrepreneur Cecelia Robinson in 2012, and now worth more than $100 million.
It comes a year after the launch of Bargain Box, which was designed for more budget-conscious families and those seeking better value-for-money.
