When it comes to finding the right meal plan, you have to start somewhere. Start with writing down what you eat in a food diary, calculate the calories you’re consuming daily (ex: 3,000 without protein shakes), and break those up into six meals (ex: 500 calories each), says Heath. Then, choose a macronutrient ratio. For example, the 40% protein, 40% carbs, 20% fat ratio is what Heath used to get bigger when he first started bodybuilding. “Buy a food scale, learn how to use it, and you may even have to learn to use the metric system, like grams instead of ounces,” Heath says. “You need to train your body to process food quickly, so eat every three hours.”
Women who train hard and reach low body fat levels, say under 10 percent, may be at risk of losing their periods as a result of hormonal disruption to estrogen production. Exercise-induced estrogen declines can result in bone loss in a way similar to that which occurs at the menopause. Loss of periods from athletic training is not uncommon but does require that you see a doctor, or better still, a sports physician and sports nutritionist to assess what is required to address the problem. Calcium supplements may be a part of the solution if bone health is likely to be affected.

Synthesis primarily takes place in the kidney and liver, with creatine then being transported to the muscles via the blood. The majority of the human body's total creatine and phosphocreatine stores is located in skeletal muscle, while the remainder is distributed in the blood, brain, and other tissues. Typically, creatine is produced endogenously at an estimated rate of about 8.3 mmol or 1 gram per day in young adults. Creatine is also obtained through the diet at a rate of about 1 gram per day from an omnivorous diet. Some small studies suggest that total muscle creatine is significantly lower in vegetarians than non-vegetarians, as expected since foods of animal origin are the primary source of creatine. However, subjects happened to show the same levels after using supplements.
