Testosterone works hard in the body, maintaining everything from bone density to muscle mass to sex drive and beyond. A significant drop in testosterone levels can result in a reduced sex drive, increased body fat, decreased motivation, and sleep problems like insomnia. These symptoms can add up to chronic low energy, and mental and physical fatigue.
As the name says, a low-carb diet restricts the type and amount of carbohydrates you eat. Carbohydrates are a type of calorie-providing macronutrient found in many foods and beverages. Many carbohydrates occur naturally in plant-based foods, such as grains.
Many folks seem to think that eating according to a Paleo diet means going super-duper low-carb and consuming gobs and gobs of meat and animal fat. But for me, Paleo looks more like this: Yes, high-quality proteins and fats are part of the equation, but so are lots of vegetables and even (gasp!) carbohydrates.
