Scientists have discovered the holy trinity of weight loss.
Keeping a food journal; not eating out and never skipping meals, a new study says, all may be key in keeping the weight off.
"The food journal helps you keep track, in real time, of what you are eating," Anne McTiernan, of the Fred Hutchinson Cancer Research Center in Seattle, reported Fox News.
"Restaurant eating, on the other hand, makes it difficult to know what you are eating, and the serving sizes are often large enough for several people. So, it's difficult to keep an account of what you eat if you don't know what's going into the food."

In the study at the Fred Hutchinson Cancer Research Center, researchers found that women who practiced each of these habits lost five to eight pounds more than women who did not partake in such activities.
McTiernan and her team looked at the habits of 123 volunteers between ages 50 and 75.
During the year-long study, the participants lost, on average, 10 percent of their body weight, said ABC News.
Those who practiced all three of the habits described, saw significant weight loss compared to the other participants.
The study was published in the Journal of the Academy of Nutrition and Dietetics.
