Are you storing excess energy or not? Are you adequately muscled? Are you metabolically healthy or not? These are the three questions that factor into a nutritional strategy.

From there, you can determine whether to maintain or decrease caloric intake, maintain or increase protein intake, and undertake additional tools like exercise to improve metabolic health. Over 50% of people will likely find themselves in the over-nourished camp.
