The 3-4-5 Rule for Fast Weight Loss

Meet the 3-4-5 rule! It's not a diet or a cleanse, but it's a slim down strategy so effective we think it may be one of our best weight loss tips yet!

We're just going to come right out and say it: trying to lose weight can be plain awful. And that's because most diet plans call for tiny portions and super-human willpower—two things that leave the majority of us super hangry (hungry + angry = hangry). If that sounds familiar, you're definitely not alone. We've all been there—and it's the primary reason why we love the idea of ditching complicated and restrictive conventional diets in favor of something called the 3-4-5 rule.

While following the rule, dieters consume 300 calories for breakfast, 400 calories for lunch, and 500 calories for dinner, for a total of 1,200 calories per day. (That's an ideal amount for a woman who's looking to slim down and lose her love handles). What makes that strategy so effective? "It keeps energy levels relatively even throughout the day and prevents people from skipping meals, a diet no-no that can result in eating too much later on," explains Isabel Smith, MS RD CDN. Another reason this strategy is so sustainable: "Consistently eating throughout the day also promotes satiety," says Smith, so you'll never go hungry.

This plan doesn't require you to relinquish chocolate for lettuce, either. You can eat whatever you want as long as it stays true to each meal's calorie requirements. Of course, we strongly recommend relying on high fiber foods, fresh produce, and quality sources of protein as your primary fuel, but that doesn't mean you can't allow yourself some room for indulgences—and we'll show you how. Our examples below demonstrate exactly what three perfect days of 3-4-5 eating looks like. Give 'em a peek to plan out your own perfect week of eating for weight loss!
