One woman says it's all about the hashtags.
In fact, Kathleen Vuong (@whatkateats) lost 10 pounds after starting a #fooddiary account. Here's her advice on using Instagram as part of your slim-down plan:
Instead of "Awesome lunch today!" write "Spicy salmon and fish roe salad for lunch with an iced jasmine green tea." Specific captions help you remember (and re-create) meals.
"I'll make and eat healthy foods, like a colorful salad, because veggies will photograph better than a ham and cheese sandwich," Vuong says. "They usually get more likes, so it's positive reinforcement."
Searching ones like #healthyeats helped Vuong find nutritious meal inspiration, and including them on her own posts drove traffic to her feed.
