Testosterone is a hormone produced in the male testes. During a boy's pubescent years (ages 9 to 14), there is an increase in production that leads to male secondary sexual characteristics such as a deeper voice, more muscle mass, facial hair growth and enlargement of the Adam's apple (among others). Some teenage boys experience these puberty changes at later ages than others. The timing of puberty is often genetically determined (through heredity), but other factors can play a role in delaying it, such as poor nutrition, physical trauma and certain diseases. Stimulating testosterone production naturally is possible in teen boys, although in rare cases hormone therapy may be needed to trigger and complete puberty.
Harvard researcher, Professor Amy Cuddy, showed that spending two minutes in a “Power Pose” increased testosterone and decreased cortisol (the stress hormone). The “Power Pose” is simply standing (or sitting) tall with your chin up, arms and legs wide and uncrossed. Just doing this has a profound impact on your hormone levels and in her study Professor Cuddy showed a 20% increase in testosterone after just 2 minutes in the “Power Pose.” If you walk around with rounded shoulders or cross your arms and legs throughout the day, take 2 minutes and raise your testosterone!
Wondering about the lack of veggies on this list? That’s because B12 is found almost entirely in animal products; vegetable sources have negligible levels of the nutrient. Sorry, vegetarians, but that extends to regular tofu, which is a good source of protein — but zilch B12. The exception is fortified tofu, such as Nasoya Tofu Plus, which is pumped up with additional nutrients, including B vitamins. A 3-ounce portion also contains 7 grams of muscle-friendly protein. If you’re a vegetarian or vegan whose libido has gone limp, you may want to do a cost-benefit analysis of tofu as a protein source and consume it sparingly, as some studies have shown that it can lower testosterone levels. If you’re concerned, you can always double down on these testosterone-boosting foods .
