Spending a little time each day writing down what you eat and drink could boost your chances of weight-loss success.

In a new study published in the journal Obesity, 142 people who were overweight or obese logged their meals and held online group sessions about weight-loss strategies for six months.
Researchers found it took just 15 minutes each day to log meals, and those who did so more frequently saw the most weight loss.
“The people who logged, and consistently logged, lost more weight than those who didn’t,” says Leslie Heinberg, PhD, Director of Enterprise Weight Management, who did not take part in the study.
“The people who had the most weight-loss success – losing 10 percent or more of their body weight – were the ones most likely to log, log multiple times a day and keep it up throughout the entire six months.”
The study reinforces what experts have known for years – that keeping a food journal is an effective tool for those looking to lose, or even just maintain, their weight, Dr. Heinberg says.
When it comes to making a lifestyle change, it can be hard to start if you don’t have any data. She says a food diary can act as a “GPS” to help guide people to where they need to be.
Make meal tracking second nature
Dr. Heinberg says the key to success is keeping up with logging your food over time.
“This is something to really put into your day and make it part of your routine,” she says. “You don’t question whether you want to brush your teeth every day because it’s part of your routine. Likewise, keeping a food diary needs to be something that you just do as part of your routine, because you know it’s going to lead to your ultimate goal.”
Most of us spend more than 15 minutes a day on social media and email, she points out, and there are a multitude of apps that make it fairly easy to help us reach our health goals.
“I think this study is so important because it shows, without a really big investment in time, that you’re much more likely to reach your weight management goals than if you’re not logging,” she said. “Getting this information on what is working for you, what your high-risk situations are, what the good days versus the bad days are – it is all data that’s going to help you figure out the best route to your ultimate goal.”
