7 Ways To Lose Weight Even If You Never Get Enough Sleep

You know that high-intensity interval training burns serious calories, but they can backfire if you haven’t been hitting the sack. These workouts can actually hinder fat loss because they increase the levels of the stress hormone cortisol in your already stressed-out, sleep-deprived bod, says Erica Suter, C.S.C.S. What’s more, since you need lots of energy to get through a HIIT workout, you’ll get less out of it.

Instead, stick to less-taxing strength workouts, lifting moderate-to-heavy weight and taking breaks. Though you’re not working as intensely, focusing on multi-join movements, like squats, deadlifts, pullups, pushups, dips, rows, and lunges will help you boost your metabolism and burn more calories, says Albert Matheny, R.D., C.S.C.S., co-founder of SoHo Strength Lab and Promix Nutrition advisor.
