3-D Nutrition

Justin Robinson, MA,RD,CSSD,FAFS,CSCS

 

At Rehab United, we apply a 3-dimensional approach to all aspects of our rehabilitation, training and conditioning.  In regards to nutrition, the 3-D model represents energy intake, storage and expenditure.

 

  • Intake: Energy intake includes calories from foods and beverages (calories from beverages add up quicker than any others).  Carbohydrates and protein contain 4 Calories (kcal) per gram, fat contains 9 per gram, and alcohol contains 7 per gram. 
  • Storage: We store energy in our body as carbohydrate (glucose and glycogen), protein (muscle tissue), and fat (adipose tissue).  How we store energy affects our expenditure, i.e. muscle tissue requires more energy at rest than fat; therefore, increasing muscle mass can increase metabolism and accelerate weight loss.
  • Expenditure: We expend energy as structured activity (running, cycling, weight training, etc.) or unstructured activity (activities of daily living).  For most people, though, our metabolism (Resting Energy Expenditure) comprises the greatest contribution of energy expenditure.

 

In short, energy intake has the greatest effect on weight management; i.e. reducing intake by 500-1000 kcal per day is typically easier than expending an extra 500-1000 kcal.
