Scientists make weight loss claim

Australian scientists believe they may have discovered how to help people lose weight without cutting back on food.


If humans react like mice, the find could help develop fat-burning drugs



Researchers in Melbourne found that by manipulating fat cells in mice they were able to speed up metabolism.

After removing a particular enzyme, scientists found the mice were able to eat the same amount as others but burn more calories and gain less weight.

The breakthrough could pave the way for fat-burning drugs and also help to combat diabetes.

The research found that mice in which the angiotensin converting enzyme (ACE) had been removed were, on average, 20% lighter than normal mice and had up to 60% less body fat.

Because of their faster metabolisms, it also appeared they had less chance of developing diabetes because they processed sugar more quickly.

Drugs which impair the action of ACE in humans already exist, and are used to combat high blood pressure.

The latest research could help the development of weight loss pills.

The question is whether they will have the same slimming effect on people as they have done on mice.

De-Stress in Mere Minutes

I'm not necessarily the meditating type — sitting still and doing absolutely nothing is a personal form of torture for me. (I find this out every time I'm on vacation!) But I know I need to reconsider: Studies have shown that aside from reducing stress and boosting mood, meditation can ease chronic pain and improve your immune system. You don't have to spend hours on end to become calmer, either. Try these simple, quick ways to savor the moment. No "Om" required!

In the shower
Face the water, letting it cascade onto your head. Take three deep, slow breaths. Pay attention to the sensation of the spray, the smell of your soap and shampoo, and the sound of water hitting the tub. Imagine you're bringing your troubles to your skin's surface and washing them away. Close your eyes and slowly repeat, "I feel refreshed," aloud three times, focusing on each word and savoring your serene, clean feeling before stepping out.

At your desk
Close your eyes and take five deep, relaxing breaths, emphasizing the exhale. Try this visualization technique, which I learned in sports: Consider the task you're about to tackle. Call to mind a talent of yours (creativity, diligence, enthusiasm) that will be key to succeeding at the task. Evaluating your resources will help you marshal your efforts and succeed. Before you open your eyes and get started, envision the assignment completed and done well. It will be soon!

While walking
Before you set out (sans iPod and cell phone), straighten up and tuck your tummy and your rear end in to feel taller. Walk slowly, focusing on each body part in isolation. First tune in to your knees as each one bends and raises, then your hips as they shift and rotate, and next the heel and ball of your foot as it meets the ground. Then focus on your arms next as they pump, then your neck, which is elongated. Pay attention to your stride for at least 10 minutes. By reconnecting to your body, you'll arrive revived. Another great way to be mindful while you exercise is through yoga — take our "Find Your Yoga Style" quiz to figure out which kind compliments your lifestyle best.

On your commute
Raise your eyebrows and hold for a count of three. Let it go and take a deep breath. Do this twice. (Don't worry, the wrinkles won't stay!) Repeat with each body part, tensing and relaxing your shoulders, your arms, moving downward along your body. Sit quietly, noticing how relaxed your muscles — and mind — feel when you're through. Relaxed muscles require less oxygen, so your breathing will slow and your heart rate and blood pressure will also decline. As your body falls naturally into a state of calm, your mood will follow suit.

4 stealthy ways to sneak in fitness

Fitness is good for you. Big fat duh.

But with all of the gym promotions and Biggest Loser-type makeover shows, we get so focused on how exercise makes us look that we sort of lost the entire point of fitness: to make your body healthier. Healthy isn't about how you look (just ask any one of the dozens of starving starlets in Hollywood who aren't physically strong enough to carry two sacks of groceries) but rather the inner workings of your blood and guts that never ever get mentioned on the cover of a glossy. Check it: not only do you help your heart get stronger so that it can do a better job of pumping blood, but when you are out of breath, it's because your body needs more red blood cells, so it starts cranking out more of those bad boys and then your physical machine breathes more efficiently. Plus, you are just not going to believe what's going on at the cellular level.

This is all very cool and exciting, but what if you rarely exercise so your bod hasn't started doing all of the great stuff it needs to do? What if you just plain old don't like to sweat? Here are five kick starts to get your factory making those red blood cells and building muscle.

* Shake your booty. Call up the friends, put on a pair of solid boots and go dancing! Make sure you go with a sturdy heel, like a stacked wedge. Spikes look awesome, but you'll be aching in all the wrong places only a few songs in.

* Take a trip! Instead of a rental car or taxis, get a bike, canoe or a backpack. It's amazing how much more more enjoyable it is to just walk around in a strange city or country.

* Pick up the Honey Do list. You'd be amazed how much you work your muscles just by raking, gardening, painting, putting in a tile floor or cleaning out the garage. There's a reason that so many of those construction workers are hard bodies.

* Play a sport. This seems like a no-brainer, but how many of us actually do this? And yet, think of the last time you played tennis, volleyball or even horseshoes with a group of friends. It was fun, right? Plus, think of all the incredible activities that you've always wanted to try! Rock climbing? Snowboarding? Boxing? Fencing? Triathlon? What are you waiting for?

Is your multivitamin hurting you?


Do you take antioxidants or a regular multivitamin? Turns out you might not need to, according to new research in the Cochrane Review that refutes the long-held belief that antioxidants prevent disease or cancer.

Researchers conducted a meta-analysis of existing studies, pertaining to more than 200,000 people, and found that antioxidant supplements--vitamins A, C, and E; beta-carotene; and selenium--do not prevent heart disease or cancer, do not forestall death, and may even increase mortality risk slightly.

But the phrase "may increase mortality risk slightly" is important to put any risk in context. Given the large pool of people analyzed, researchers would have noticed right away if there was any significant risk of death associated with the supplements. So if all we have is a hint of modest harm, the risk is clearly quite small.

This finding is disappointing and counter-intuitive. How can antioxidant supplements fail to help us and maybe even harm us slightly?

There are several likely answers. First, we may have the doses wrong. Just because some of a thing is good does not mean more is better. Second, maybe we have the wrong combinations. Antioxidants in foods come packaged with many other nutrients, and they all work together. When we separate that harmony, we may wind up with sour notes. Third, the participants in most of these trials were already ill. Perhaps antioxidants have different effects before chronic disease begins. They might even help prevent disease if taken earlier.

In general, my advice about a supplement is to remember it's not a substitute for a healthy diet and lifestyle. Use supplements thoughtfully. Talk to your doctor to be sure there is a sound reason, tailored to your health, for each one you take. Don’t assume that just because a clever ad makes a supplement sound good that it truly is.

I take an Omega-3 fish oil supplement every day, and recommend the same for most of my patients. I believe a multivitamin or mineral supplement is a good idea for many of us, despite a lack of research that shows a clear benefit. (I also like a supplement called Juice Plus, which compresses the nutrients from fruits and vegetables into capsule form, while preserving their native proportions.)

Based on the science we have at present, there is no reason to fear any antioxidant supplements you may have been taking--the potential for harm is minimal. But remember: No pill bottle holds an alternative for a healthy, active lifestyle.

5 Veggies That Make Any Salad Super-Healthy

Five salad veggies have turned out to be antioxidant superstars. Toss a handful into any bowl and you'll instantly up your defenses against everything from wrinkles to heart disease and even help make your RealAge younger. Punch up the antioxidant power even more by seasoning some olive oil and vinegar with a few of the herbs and spices below. Health food doesn't get any easy-breezier!

5 Superstar Veggies
Artichokes
Radishes
Broccoli
Red chicory
Leeks

7 Stellar Seasonings
Sage
Rosemary
Marjoram
Thyme
Tarragon
Cumin
Fresh ginger
Garlic


The #1 Vegetable
Of the 27 vegetables scientists studied, the almighty artichoke led the antioxidant pack. Plus it's rich in both fiber and folate, two good-for-you nutrients. Look for plump but compact globe-like artichokes with thick, green, fresh-looking scales.

The Runners-Up
Radishes, broccoli, and even luscious leeks are stocked in most supermarkets. But what's red chicory? An Italian salad favorite with an oddly appealing bitter taste. Try mixing it with romaine.

The High-Powered Herbs and Spices
Sage, rosemary, and thyme...when Simon and Garfunkel made them famous, nobody knew they had disease-fighting powers. Cumin, a spice used heavily in Indian food, is even more impressive, as is ginger. But experiment: All of these seasonings are simple ways to boost the health -- and flavor -- of any salad (soups too). Here's a get-you-started recipe.

COOL-BEANS ARTICHOKE SALAD
This elegant mix is both light and filling -- perfect to serve a few friends on a sultry night.
Serves 4

10 baby artichokes, peeled and quartered
2 cups diagonally cut asparagus
1/3 cup thinly sliced radishes
3 green onions, thinly sliced
1 19-oz. can white beans, rinsed and drained
3 cloves garlic, minced
2 tsp. lemon juice
1 Tbsp. olive oil
1/4 tsp. salt
1/8 tsp. black pepper
8 large romaine leaves

1. Steam the artichokes for 8 minutes. Add the asparagus and steam about 2 minutes more, or until crisp-tender. Drain and run vegetables under cold water. Let cool.

2. Make dressing: Whisk together garlic, lemon juice, olive oil, salt, and pepper.

3. Combine radishes, onions, and beans in salad bowl with half of dressing and toss well. Gently stir in artichokes and asparagus.

4. To serve, place 2 romaine leaves each on four plates. Divide salad equally among plates and drizzle with remaining dressing
