|Stop winging it|
So much of eating is impulsive—you're hungry and you grab whatever is there. Be proactive so you're not starving at noon and your only option is an overstuffed sandwich. Every morning, do a mental walk-through of your day to plan what you're going to eat when. If you won't be able to find something healthy, brown-bag it.
|Debloat the healthy way|
Chances are you're feeling a little puffy after the holidays. Lemons, asparagus, avocado, quinoa and ginger are all great at getting rid of your bloat; they help you lose sodium and retain less fluid. You can also try this yoga routine that relieves bloating.
|Fall in love with fermented foods|
You've already heard that probiotic foods are some of the best things you can eat for gut health. But you may not know that yogurt isn't the only source of good bacteria. Try kombucha tea, kimchi (a spicy Korean cabbage side dish) and kefir (a tart milk drink).
|Keep your own medical file|
Get a binder for your health records and test reports; also, scan them and save them to your hard drive. Having copies lets you be your own advocate. Bring them with you every time you visit a physician. That way, each doctor will be on the same page and better equipped to help you stay well.
Besides the obvious annual exams (e.g., a gynecologist visit), you also need a skin cancer check (visual screenings are key to detecting skin cancer and stopping it early—just be sure your doc is giving you a thorough screening). Also, once you hit 50, you should get a colonoscopy every 10 years.
|Set a bedtime|
Sleep is one of those things everyone knows they need more of but can't quite figure out how to get. So treat yourself like a kid and set a time you have to be in bed by (say, 11 p.m. if you wake up at 7 a.m.). An hour before, turn off all your electronics. Browsing Pinterest on your iPad up to the moment you shut off the lights is only going to make it tougher to drift off and sleep soundly.
|Check into your investments|
Most people sign up at the beginning of a job for an investment plan and never look at it again. But you need to periodically make sure it's still the right mix of stocks and bonds for your age and comfort level with risk. Spend a moment reviewing where your money is invested. A good rule of thumb: Take 100 and subtract your age to find the percentage you should have invested in stocks (a riskier choice). So if you're 40, 60 percent of your fund should be in stocks and the rest in safer investments.
|Learn your credit score|
While you can get your credit report for free every year, you have to pay to find out your actual score. It's worth it, though: This one number determines whether you can get a mortgage and what the interest rate on other loans may be. Head to myfico.com for your rating.
|Switch from manual to automatic|
Sign up for automatic bill paying for every predictable monthly bill you have. You'll avoid accidentally skipping a payment (it's even happened to me!), lower your stress and may even boost your credit score. Bonus: Some creditors give you incentives for automating your payment, like a lower interest rate on your student loans.
|Take some measurements|
Weighing yourself can be so dispiriting. You might be disappointed by the number, and some of it is water weight versus all those holiday cookies. Instead, measure three areas: around your chest, the smallest part of your waist and the circumference of a thigh. You'll get a starting point so you can see how your workouts are changing your body. (It doesn't get more motivating than losing inches!)
|Slip into a swimsuit|
If you've taken a few months (or years) off from exercise or you have some weight to lose, pools are the perfect place to work out. Swimming and water aerobics are certainly challenging, but don't put much strain on your joints.
To see faster results, follow the lead of pro athletes and squeeze in a few two-a-days. While a good goal is to exercise four days a week, in the month of January try to work out in the morning and evening on two of those days. No need to go all-out both times—the second workout should be easier, like going on a bike ride or taking a power walk. Then, in February, you can switch back to one-a-days, knowing you've already made major progress.
