Want Babies? Treat Infertility's Root Causes
Infertility isn't a standalone disease—it is a symptom of other underlying reproductive health diseases. One in six couples struggles to conceive or carry to term, and in most cases, this stems from four or more reproductive health conditions, such as endometriosis, PCOS or male-factor infertility.

Gluten Could Be Wrongly Blamed for Americans' Stomach Troubles
For many of us, gluten is a dietary villain, capable of causing all sorts of gastrointestinal troubles. Research out this week looks to complicate that narrative, however, finding that people are sometimes wrongly blaming gluten for triggering their symptoms of irritable bowel syndrome. Scientists at McMaster University in Canada conducted the study, a small, randomized trial of IBS patients. People became sicker just as often after eating food containing gluten or wheat as they did after eating food without the ingredient, they found. Gluten is likely safer to eat for those with IBS than commonly thought, the researchers say. 'These findings suggest that expectations played a major role in symptom generation and that only some of these patients could benefit from gluten or wheat restriction,' they wrote in their paper, published Monday in The Lancet Gastroenetrology and Hepatology. IBS is a complex, chronic, and relatively common condition, estimated to affect between 5 and 10% of the population worldwide (including up to 45 million people in the U.S.). Its symptoms include stomach pain, bloating, and diarrhea or constipation. Unlike the closely named inflammatory bowel disorder, IBS isn't marked by physical changes or visible damage along the digestive tract, but it can still be a debilitating burden for many, with around 20% of sufferers experiencing severe bouts. The exact causes of IBS remain unclear, though scientists have speculated it can arise from a miscommunication between the nerves found in the gut and the brain. People with IBS tend to report having specific triggers that can cause a flare-up of illness, gluten included, and often manage their condition by avoiding these triggers. The researchers behind the new study aimed to better understand gluten's potential role in IBS, so they recruited over two dozen people with IBS for their randomized, double-blinded trial, all of whom had reported improving after switching to a gluten-free diet. At first, the volunteers were randomly assigned to one of three groups. All the groups were first told to eat cereal bars for a week. One group ate bars made with flour containing gluten, the second ate bars made with wheat flour, and the third ate bars made with gluten- and wheat-free flour. Afterward, the volunteers took a break for two weeks. Then they switched to eating the bars they hadn't eaten yet for another round of testing, a process repeated twice. By the study's end, all the volunteers had eaten all three kinds of bars, though on different schedules and without knowing which bars they had eaten on a given week. A total of 28 people completed the trial. A significant percentage of people reported having worsening IBS symptoms after eating gluten or wheat bars, the study showed, but about just as often as they did after eating non-gluten/wheat bars (roughly a third experienced worsening IBS during each of the three conditions). 93% of participants also reported having adverse events after each scenario of bar-eating. Interestingly enough, tests of the participants' stool found that only a third strictly followed their diets as instructed, with likely many fearing they would get sick. The findings are based on a very small sample size, so it's not yet certain that they apply to the general population of people with IBS tied to gluten. There are also, of course, digestive conditions clearly caused by an intolerance to gluten, particularly celiac disease. And the researchers aren't saying gluten can't sometimes be a genuine trigger for people's IBS. But they argue that in many cases, people's negative perception of gluten is causing a nocebo effect, the dark cousin of the placebo effect. In other words, someone's belief that gluten is bad for them can potentially spark or worsen the IBS symptoms seen after eating it, rather than gluten itself. The researchers say better communication and follow-up care from doctors are needed for IBS patients, given the findings. 'What we need to improve in our clinical management of these patients is to work with them further, not just tell them that gluten is not the trigger and move on. Many of them may benefit from psychological support and guidance to help destigmatize gluten and wheat and reintroduce them safely in their diet,' said senior author Premysl Bercik, a professor at McMaster's Department of Medicine, in a statement from the university. That may be easier said than done, though. The researchers note that most patients, upon learning the team's findings, staunchly refused to entertain the idea of gluten not being a trigger for their IBS symptoms. So it looks like gluten may need a promotional campaign to win back its reputation.

Lose Weight With Strength Training -- Here's How to Cut Fat by Lifting
Weight loss isn't easy, especially when you aren't sure exactly what kind of activity to do to get there. Although cardio is known to be the go-to for getting to that ideal body fat percentage, you can totally lose weight with strength training. It's easy to ignore strength training when you're focused on weight loss, but it's an excellent way to change your body composition, boost your metabolism and lose weight by burning fat. There are a ton of Reddit threads discussing whether aerobic exercise is the best for strength training or whether you should do strength training. There are varied opinions on this, but we know one thing for sure -- it is definitely possible to lose weight with strength training. You can actually use strength training to your advantage even if you're not a bodybuilder or don't spend hours at the gym. Strength training can help you build lean muscle, helping your body keep burning calories even when you're not working out. It's also not as heavy on the joints as high-impact cardio, which makes it a good place to start for all kinds of fitness levels. Whether you're just getting started with resistance exercise or aren't sure where to start, even two sessions a week can make for game-changing results in your fitness routine. Looking for more fitness tips? Check out how many calories you need to burn to lose weight, simple ways to shed body fat at home and how to achieve that elusive balance of losing weight while gaining lean muscle. Strength training can help you burn more versus strength training There's a constant back-and-forth argument about which is more efficient in reaching your ideal physique: cardio or strength training. According to New York City-based personal trainer Oscar Colon IV, cardio is ideal for burning more calories during a workout session -- and it's key to keeping your heart strong -- but strength training affects your body differently. "Strength training has a two-pronged effect because you burn calories during the workout and during the recovery and restoration of muscle groups you worked," he says. As a result, you get more results for your effort. It's still a good idea to incorporate cardio and strength training into a well-balanced fitness plan, so you can reap all the benefits. How much you do of one or the other may also depend on your current goals. If you're training for your first marathon, cardio will be your main focus as you build endurance, whereas strength training will be a priority when you're trying to get stronger or build muscle. Buillding muscle helps you burn calories even at rest. Getty Images How muscles affect your ability to burn fat As mentioned, strength training can help you burn more calories during and after your workout. This is thanks to the lean muscle you gain as a result of strength training. If your goal is to lose weight, having more lean muscle can help the process. This also means that the more lean muscle you have, the higher your resting metabolic rate will be. Your resting metabolic rate, or RMR, refers to the total number of calories your body burns when it's at rest. Biologically speaking, resting metabolism aids your organ functions, neurological functions, breathing and blood circulation. Rachel MacPherson, an American Council of Exercise-certified personal trainer, performance specialist and Garage Gym Reviews expert, explains that muscle is metabolically active, meaning it burns calories even at rest. Although the effect is small, it's significant and does add up over time. "This also helps to counteract the decline of metabolism and muscle mass as you age, which can contribute to middle-age weight gain," she says. Strength training also has fat-burning benefits when you're fresh off a workout. "Excess post-exercise oxygen consumption is the process of your body regulating itself back to homeostasis after a strenuous workout," Colon explains. In other words, you're still burning calories as you recover, because your body stays warm for a while as it cools down. Studies have shown that beginners tend to put on muscle faster than those experienced with strength training. Getty Images How long it takes to put on muscle Now that you know that lean muscle is the key component in fat burning, you're probably wondering how long it takes to build muscle. This will vary from person to person, as genetics, hormones, gender, diet and other factors play a role in how much muscle you put on and how quickly. "If you consistently train three to four times a week for 30 minutes each session, you should realistically start to see results in three to four weeks," Colon says. MacPherson says you can put on muscle mass each week, and doing a 12- to 16-week hypertrophy training program is ideal for seeing a significant amount of muscle gain. "You can expect upwards of five to 10 pounds of muscle gain during this time," she says, adding, "As you become more advanced you will need to work harder for less gain but you will still see results." That's another interesting aspect of strength training: If you're a beginner, you tend to have an advantage over someone more experienced when building muscle. This is what some people refer to as "newbie gains," which refers to your body's muscle-building response to lifting weights because it's not used to this kind of stimulus. Research has shown that untrained individuals (those with minimal to no strength training experience) can put on muscle faster than someone who's already experienced with strength training. Generally speaking, men and women also have different results when building muscle mass. "Men can build muscle mass much easier and faster than women due to testosterone, while women can still build substantial amounts of muscle but will never look as large or full as men unless they use anabolic steroids," says MacPherson. "It's vital that women lift enough volume and weight while also eating enough to support muscle gain." This means letting go of the old-school mentality of dieting and shrinking yourself, otherwise it'll inhibit your ability to build muscle. Besides a well-regimented workout plan, a diet that supports muscle-building is key too. "In order to build muscle, you need to eat in a calorie surplus with plenty of protein," MacPherson says. She explains that eating in a surplus will lead you to gain some body fat, which is normal and necessary to gain muscle. "You can lose it afterward and it will be easier since your body has become better at burning calories due to increased muscle mass." Strength training has excellent health benefits. Getty Images Other benefits to lifting weights Besides helping you metabolize and get stronger, strength training has other benefits. Colon says it's also important for bone development and density. "Weight-bearing exercises put temporary stress on your bones, sending a message to bone-building cells to take action and rebuild bones stronger," he says. Another benefit tied to strength training is reducing your risk of injury by improving the strength, range of motion and mobility of your muscles, ligaments and tendons. "This can reinforce strength around major joints like your knees, hips and ankles to provide additional protection against injury," Colon says. Another plus is for your heart, because strength training is shown to help decrease blood pressure. You can also reduce the chances of type 2 diabetes, improve blood circulation and lower LDL (bad) cholesterol. Exercise has been shown to even have a positive effect on your mental health and resistance training has been found to ease anxiety as well. Bottom line It's helpful to know the unique effects strength training has on your body as you establish a consistent exercise routine. Not only will you naturally burn more fat by having more muscle but you'll maintain strength as you age and improve other functions of your life as well. If you don't have access to a gym, you can start your exercise regimen at home and still get the same results, as long as you have the proper equipment. Even if your goal isn't weight loss or body recomposition, strength training provides many benefits that make it worth adding to your lifestyle, and it'll only improve your well-being in the long run.

If you've been considering investing in a sleek wearable to help you on your wellness journey that isn't as heavy and chunky as a smartwatch, this is an exceptional deal.
