Heat-Building Yoga

This yoga sequence is all about burning your own internal fire through fierce twists and loads of vinyasas. The 11 poses in this twist-out-your-toxins yoga sequence will get all your muscles working — it's the perfect sequence to detox after a day (or week) of not eating the healthiest.

Fat-Burning Dinner: Roasted Fish With a Flat-Belly Salad

Eating fish can promote weight loss since lean protein fills you up and sustains your energy, which prevents you from oversnacking later. Plus it's a great source of omega-3 fatty acids, which we all could use. If you've never made fish, here's an incredibly easy recipe that's low in calories (160!) and only requires four ingredients. Here's a video of Bob Harper showing you how easy it is, so it's absolutely foolproof! Enjoy your serving of protein with the flat-belly salad below.

Made with fiber-rich Bibb lettuce, this salad gets an extra boost from hydrating cucumbers that help flush out the digestive system. The enzymes in the pineapple ease digestion, and besides adding a unique sweetness to the dish, blueberries are proven to diminish belly fat. Avocado and almonds not only add bloat-reducing fiber, but since they're both considered MUFAs (monounsaturated fatty acids), they also help keep belly fat at bay. Topped with a homemade lemon chia seed dressing, this salad is amazingly delicious.
