Although lower testosterone levels have traditionally been considered something that affects older men, research suggests that this hormone starts to decline after a man hits a rather young 30 years old. Levels that get too low can result in a lower sex drive and problems with performance, depression, and even issues with keeping focus on a task at hand.Due to the sensitive nature of this topic, going to a health care provider and talking candidly about your concerns may not be high on your to-do list. So, if you think (or know) that your testosterone levels need a boost, here are some ways to achieve this goal naturally, yet affectively:Drop your excess fatResearchers have found a link between being overweight and having low testosterone levels; therefore, eliminating your love handles and beer belly may be enough to keep this hormone where it should be.Cut out sugarThe more sugar you consume, the lower your levels of testosterone, so reducing or eliminating the sweet stuff from your diet will work wonders. While you may initially miss satisfying your sugar cravings, your body will soon feel better than ever without it, making it a good trade-off.Engage in interval trainingWhen you put your body through short bursts of physical activity, it raises your testosterone levels. One workout option to try is warming up for 2 minutes, then alternate between high and low intensities (30 seconds to 1 minute of each) for the next 16 minutes, followed by a 2 minute cool down.Get enough vitamin DGood for your sex drive and sperm count, this particular vitamin also improves your mood and gives you stronger bones. You can get more vitamin D in your body by spending 15 minutes daily in direct sunlight, taking a supplement, or eating D-rich foods such as fatty fish (salmon, tuna), egg yolks, and vitamin fortified cereals and juices.Follow these suggestions and not only will you increase your testosterone naturally, but you’ll be healthier too. It’s like a two-for-one!
