Your body type in a nutshell: You can put body fat on easily, and it can be tough to lose weight. Your upper and lower body can fall into different body types, so you may notice you store fat up top or in your rear or thighs, says Sims.

Your ideal routine: Calm and restorative. Lowering your levels of cortisol, the stress hormone that prompts your body to store fat, is key. First up: Practice mindfulness meditation. The technique, where you sit quietly and focus on your breath, has been shown to help reduce morning cortisol levels, therefore reducing stress.

Finding an exercise you love and sticking with it is another powerful buffer against stress. Though you will want to be mindful of how you fuel up before extreme exercises. "Hard workouts will cause your body to release a lot of cortisol during recovery, stimulating your body to put on fat." says Sims. To buffer that effect, you should eat a pre-exercise snack instead of going to the gym without anything in your stomach. A light bite that includes both carbs and protein, like a little vanilla protein powder stirred into coffee with a small banana will power you through without overloading on calories, says Sims.

Come breakfast time, choose metabolism-boosting eats. That means higher fat (avocado, nuts) and protein (eggs, Greek yogurt, cottage cheese) plus fewer carbs (oats, whole grains), which will work well for fat-burning and keep you satiated until lunch.
