7 Reasons You’re Still Hungry—Even After You Just Ate!

Do you sometimes feel ravenous, even though you just polished off a tasty lunch, a full dinner, or a midnight snack? Some food ingredients can trick our bodies into not recognizing when we’re full, causing “rebound hunger” that can add inches to our waistlines. But these simple tweaks can help quiet your cravings.


You Drink Too Much Soda
Sodas, iced teas, and other sweetened beverages are our biggest source of high-fructose corn syrup—accounting for about two-thirds of our annual intake. New research from the University of California at San Francisco indicates that fructose can trick our brains into craving more food, even when we’re full. It works by impeding the body’s ability to use leptin, the “satiation hormone” that tells us when we’ve had enough to eat.



Your Dinner Came Out of a Can
Many canned foods are high in the chemical bisphenol-A, or BPA, which the Food and Drug Administration recently stated was a chemical “of some concern.” Exposure to BPA can cause abnormal surges in leptin that, according to Harvard University researchers, leads to food cravings and obesity.



Your Breakfast Wasn't Big Enough
After following 6,764 healthy people for almost 4 years, researchers found that those who ate just 300 calories for breakfast gained almost twice as much weight as those who ate 500 calories or more for breakfast. The reason: Eating a big breakfast makes for smaller rises in blood sugar and insulin throughout the day, meaning fewer sudden food cravings.



You Skipped the Salad
Most Americans don’t eat enough leafy greens, which are rich in the essential B-vitamin folate and help protect against depression, fatigue, and weight gain. In one study, dieters with the highest levels of folate in their bodies lost 8.5 times as much weight as those with the lowest levels. Leafy greens are also high in vitamin K, another insulin-regulating nutrient that helps quash cravings. Best sources: Romaine lettuce, spinach, collard greens, radicchio.



You Don't Stop for Tea Time

According to a study in the Journal of the American College of Nutrition, people who drank one cup of black tea after eating high-carb foods decreased their blood-sugar levels by 10 percent for 2 and a half hours after the meal, which means they stayed full longer and had fewer food cravings. Researchers credit the polyphenolic compounds in black tea for suppressing rebound hunger.



You're Not Staying Fluid

Dehydration often mimics the feeling of hunger. If you’ve just eaten and still feel hungry, drink a glass of water before eating more, and see if your desires don’t diminish.



You're Bored
Researchers at Flinders University in Australia found that visual distractions can help curb cravings. To test yourself, envision a huge, sizzling steak. If you’re truly hungry, the steak will seem appealing. But if that doesn’t seem tempting, chances are you’re in need of a distraction, not another meal.

Is Milk Really Healthy for You? Learn the Facts


"Milk is a deadly poison," according to the Dairy Education Board. In fact, if you peruse this special interest group's Web site, notmilk.com, you'll find dozens of articles about the purported evils of this popular beverage. One claim, for example, is that milk from cows contains cancer-causing hormones and dairy industry dollars have kept that fact bottled up. All of which may leave you second-guessing your next sip.

However, as a nutritionist, I've found that most men thrive on milk, whether their goal is to lose fat or build muscle. So to be sure it's safe, I've investigated all the anti-milk claims, sifting through the research while also turning a critical eye to pro-milk propaganda. After all, the only agenda I have is my clients' health. The result: all your milk questions, answered.



Is Milk a Fat-Burning Food?
Maybe. In a 6-month study, University of Tennessee researchers found that overweight people who downed three servings a day of calcium-rich dairy lost more belly fat than those who followed a similar diet minus two or more of the dairy servings.

In addition, the researchers discovered that calcium supplements didn't work as well as milk. Why? They believe that while calcium may increase the rate at which your body burns fat, other active compounds in dairy products (such as milk proteins) provide an additional fat-burning effect.

Of course, the key to success is following a weight-loss diet to begin with. After all, downing your dairy with a box of doughnuts is no way to torch your gut.



Does It Build Muscle?
Absolutely. In fact, milk is one of the best muscle foods on the planet. You see, the protein in milk is about 20 percent whey and 80 percent casein. Both are high-quality proteins, but whey is known as a "fast protein" because it's quickly broken down into amino acids and absorbed into the bloodstream. That makes it a very good protein to consume after your workout.

Casein, on the other hand, is digested more slowly. So it's ideal for providing your body with a steady supply of smaller amounts of protein for a longer period of time—like between meals or while you sleep. Since milk provides both, one big glass gives your body an ideal combination of muscle-building proteins.




Do Hormones Make Milk Unhealthy?
Not unless you're injecting the milk. Here's the full story: In 1993 the FDA approved the use of recombinant bovine growth hormone (rBGH) in cattle. This practice resulted in greater milk production at less cost to the dairy farmer, a savings that has been passed on to you at your local supermarket. But it has also sparked much controversy, because rBGH boosts milk's concentration of insulin-like growth factor (IGF), a hormone that's been linked to cancer.

Unlike steroid hormones, which can be taken orally, rBGH and IGF must be injected to have any effect. That's because the process of digestion destroys these "protein" hormones. So drinking milk from hormone-treated cows doesn't transfer the active form of these chemicals to your body. However, there is one ethical downside to consider: It's not good for the cows. Canadian researchers discovered that cows given hormones are more likely to contract an udder infection called mastitis.




What About Antibiotics?
No one really knows. Some scientists argue that milk from cows given antibiotics leads to antibiotic resistance in humans, making these types of drugs less effective when you take them for an infection. But this finding has never been proved.

If you're uneasy, you can purchase antibiotic-free (and typically hormone-free, as well) milk from specialty grocers, such as Trader Joe's or Whole Foods, or select USDA-certified organic milk, which is available at most supermarkets.



Skim or Whole?
It depends on your taste. While you've probably always been told to drink reduced-fat milk, the majority of scientific studies show that drinking whole milk actually improves cholesterol levels, just not as much as drinking skim does.

One recent exception: Danish researchers found that men who consumed a diet rich in whole milk experienced a slight increase in LDL cholesterol (six points). However, it's worth noting that these men drank six 8-ounce glasses a day, an unusually high amount. Even so, their triglycerides--another marker of heart-disease risk—decreased by 22 percent.

The bottom line: Drinking two to three glasses of milk a day, whether it's skim, 2 percent, or whole, lowers the likelihood of both heart attack and stroke—a finding confirmed by British scientists.

If you're dieting, the lower-fat option is an easy way to save a few calories. When it comes to building muscle, though, whole milk may be your best choice: Scientists at the University of Texas medical branch in Galveston found that drinking whole milk after lifting weights boosted muscle protein synthesis—an indicator of muscle growth—2.8 times more than drinking skim did.

6 Habits to Chisel a Solid 6-Pack

If you can't see your abs, don't assume it's because you're missing out on a magical abdominal exercise or secret supplement. Blame your mindset.

You see, losing belly flab is a boring process. It requires time, hard work, and most important, dedication. Take the right steps every single day, and you'll ultimately carve out your six-pack. But if you stray from your plan even a few times a week—which most men do—you'll probably never see your abs.

The solution: six simple habits, which I teach to my clients to help them strip away their lard for good. Think of these habits as daily goals designed to keep you on the fast track to a fit-looking physique. Individually they're not all that surprising, but together they become a powerful tool.

The effectiveness of this tool is even supported by science. At the University of Iowa, researchers determined that people are more likely to stick with their fat-loss plans when they concentrate on specific actions instead of the desired result. So rather than focusing on abs that show, follow my daily list of nutrition, exercise, and lifestyle strategies for achieving that rippled midsection.

The result: automatic abs.


Wake Up to Water

Imagine not drinking all day at work—no coffee, no water, no diet soda. At the end of an 8-hour shift, you'd be pretty parched. Which is precisely why you should start rehydrating immediately after a full night's slumber. From now on, drink at least 16 ounces of chilled H2O as soon as you rise in the morning. German scientists recently found that doing this boosts metabolism by 24 percent for 90 minutes afterward. (A smaller amount of water had no effect.) What's more, a previous study determined that muscle cells grow faster when they're well hydrated. A general rule of thumb: Guzzle at least a gallon of water over the course of a day.


Eat Breakfast Every Day
A University of Massachusetts study showed that men who skip their morning meal are 4 1/2 times more likely to have bulging bellies than those who don't. So within an hour of waking, have a meal or protein shake with at least 250 calories. British researchers found that breakfast size was inversely related to waist size. That is, the larger the morning meal, the leaner the midsection. But keep the meal's size within reason: A 1,480-calorie smoked-sausage scramble at Denny's is really two breakfasts, so cap your intake at 500 calories. For a quick way to fuel up first thing, I like this recipe: Prepare a package of instant oatmeal and mix in a scoop of whey protein powder and 1/2 cup of blueberries.


As You Eat, Review Your Goals . . .
Don't worry, I'm not going all Tony Robbins on you. (I don't have enough teeth.) But it's important that you stay aware of your mission. University of Iowa scientists found that people who monitored their diet and exercise goals most frequently were more likely to achieve them than were goal setters who rarely reviewed their objectives.


. . . And Then Pack Your Lunch
My personal Igloo cooler just celebrated its 19th anniversary. I started carrying it with me every day back in college. Of course, it often housed a six-pack of beer—until I decided to compete in the Purdue bodybuilding championship. (Second place, by the way.) Once I knew I'd have to don a banana hammock in public (the world's best motivator), I began to take the contents of my cooler seriously. And so should you. In fact, this habit should be as much a part of your morning ritual as showering. Here's what I recommend packing into your cooler.

• An apple (to eat as a morning snack)
• Two slices of cheese (to eat with the apple)
• A 500- to 600-calorie portion of leftovers (for your lunch)
• A premixed protein shake or a pint of milk (for your afternoon snack)

By using this approach, you'll keep your body well fed and satisfied throughout the day without overeating. You'll also provide your body with the nutrients it needs for your workout, no matter what time you exercise. Just as important, you'll be much less likely to be tempted by the office candy bowl. In fact, my personal rule is simple: I don't eat anything that's not in the cooler.


Exercise the Right Way
Everyone has abs, even if people can't always see them because they're hidden under a layer of flab. That means you don't need to do endless crunches to carve out a six-pack. Instead, you should spend most of your gym time burning off blubber.

The most effective strategy is a one-two approach of weight-lifting and high-intensity interval training. According to a recent University of Southern Maine study, half an hour of pumping iron burns as many calories as running at a 6-minute-per-mile pace for the same duration. (And it has the added benefit of helping you build muscle.) What's more, unlike aerobic exercise, lifting has been shown to boost metabolism for as long as 39 hours after the last repetition. Similar findings have been noted for intervals, which are short, all-out sprints interspersed with periods of rest.

For the best results, do a total-body weight-training workout 3 days a week, resting at least a day between sessions. Then do an interval-training session on the days in between. To make it easy on you, I've created the ultimate fat-burning plan.
Skip the Late Shows
You need sleep to unveil your six-pack. That's because lack of shut-eye may disrupt the hormones that control your ability to burn fat. For instance, University of Chicago scientists recently found that just 3 nights of poor sleep may cause your muscle cells to become resistant to the hormone insulin. Over time, this leads to fat storage around your belly.

To achieve a better night's sleep, review your goals again 15 minutes before bedtime. And while you're at it, write down your plans for the next day's work schedule, as well as any personal chores you need to accomplish. This can help prevent you from lying awake worrying about tomorrow ("I have to remember to e-mail Johnson"), which can cut into quality snooze time.

5 Simple Strategies for Bigger Muscles

Strength training today suffers from the Starbucks effect. Just as it's increasingly difficult to fight off the sprinkles and foam when you order a cup of joe, it's hard to call yourself a modern muscle maker when you do a weight-lifting move without a few added kinks.


"It's great fun to watch guys trying to do squats while standing on stability balls," says former Olympic weight-lifting coach Harvey Newton, C.S.C.S., of newtonsports.info. "But the truth is, if they just did the basics better, they'd produce the results they want without involving all the bells and whistles."

Now hold on, Harvey. Those big balls do a lot of good. On the other hand, all these half-caf mocha-latte workouts are starting to get on our nerves. Sometimes you just want to bust a move and make more muscle.

So we asked exercise experts to help us pinpoint ways to make the classic moves we all do—squats, rows, bench presses, and crunches—work better. Follow their advice and see fast results . . . without the sprinkles.


1. Tap When You Squat

Experts agree: The squat is one of the best muscle builders in a man's portfolio because of the number of muscles the exercise engages. Experts also agree that most lifters perform it incorrectly. Namely, they don't squat down far enough, nor do they place the emphasis on their glutes by anchoring with their heels. This means the glutes are never fully engaged.


New York City–based trainer David Kirsch, C.S.C.S., author of The Ultimate New York Body Plan, offers this solution: Stand in front of a weight bench. Squat down until your butt touches the bench, then immediately press through your heels back to the starting position. Using the bench forces you to squat all the way down until your thighs are parallel to the floor, so the exercise will yield better results.


2. Give 'Em a Squeeze

As you prepare to lift, contract the muscles you're working and keep them that way throughout the entire move. "You won't be able to lift quite as much weight, but your muscles will be doing more work overall, so they'll grow," says Sam Iannetta, C.P.T., owner of Functional Fitness and Wellness Centers in Boulder, Colorado. "For instance, on the bench press, imagine you're trying to bring your hands toward each other but don't move them at all, so your pecs are squeezed together. You won't believe the pump."


3. Bring the Situp Back from the Dead

"Men spend entirely too much time doing crunches, which involve only a 30-degree range of motion—way too small for significant muscle building," says Patrick Hagerman, Ed.D., C.S.C.S., a professor at the University of Tulsa. "If you want to build your abdominals, do a full situp. Your abs spend more time working dynamically under tension, so they'll grow bigger and stronger. Full situps also strengthen the hip flexors, which can get pretty weak if all you do is crunches." (To improve your crunches, add a Swiss ball.)

To do situps right, lie on your back with your feet flat on the floor, knees bent about 90 degrees, hands clasped lightly behind your head, and elbows out to the sides. Tuck in your chin, contract your abdominals, and roll all the way up until your chest nearly touches your knees. Then slowly roll back down.


4. Lose the Bench

By working while standing, you involve more muscles and burn more calories, says Douglas Lentz, C.S.C.S., director of fitness for Summit Health, in Chambersburg, Pennsylvania. "Except for a few sessions devoted to increasing mass, our athletes do almost everything standing," he says. "It engages your core, so your total strength increases."

A classic example is the bent-over dumbbell row. Most men lean over and brace themselves on a bench, then perform the exercise with one arm. Instead, assume a wide, stable stance and bend from the hips, keeping your back flat—and don't use a bench. Perform your rows from that position. You'll work your core for stability and do a bit more mid-section work. You won't be able to lift quite as much weight, but your entire body will benefit from the move.


5. Whittle While You Wait

Instead of sitting around working your mandible between sets, exercise another body part. "Supersetting helps you use your time better," says Lentz. And, if you do it properly, it builds more muscle. For the best results, alternate lower- and upper-body moves, such as a leg press followed by a lat pulldown. That way, each muscle group has time to recover between sets. Alternating upper- and lower-body exercises also keeps your heart rate revved up and stimulates your circulatory system, so you deliver more oxygen- and nutrient-rich blood to your working muscles and burn more calories.

Don't like blending upper- and lower-body workouts? Do ab work between sets. You'll be less likely to blow it off than if you save it for the end.
