Here's the thing: I'm a serial snacker. I could graze all day long. I don't like big meals, plus I've always heard the health mantra that you should eat six smaller meals rather than three big meals a day (one writer actually tried this six-meals-a-day thing, and here's how it went). But then I started keeping a food journal and realised just how much I was eating throughout the day. Sure, I was eating healthy snacks like nuts, fruit and cheese, but I was eating too much of them. I wondered, was my snacking habit a bad one?

Nutrition experts disagree on whether snacking is smart or not, but one thing they all agree on is that you should be careful which foods you reach for, and avoid eating mindlessly.  For many, snacks account for up to 25% of our total daily caloric intake, so smart snack choices are essential, advises Dr Morton Tavel.

"I don't think snacking is inherently bad for you," says dietitian Ana Reisdorf. "I am a believer that if you are physically hungry you should eat, but snacking can easily get out of control when we're eating for reasons other than hunger, like boredom or fatigue."

With these warnings in mind, I decided to go snack-free for a month. I would eat breakfast, lunch and dinner only (trying not to alter my meals much from my usual ones), and stick to healthy, fibere-filled meals with lots of fruits and veggies. No mid-morning or mid-afternoon snacks, and especially no late-night munching. Here's what I learned from my month without any snacks—and where experts said I went wrong.
