In this this episode, Ryan and I talk about... Why food volume matters. 

  • Humans evolutionarily not adapted to higher density foods especially fat+ carb hyperpalatable hyper ED combinations. Humans are inaccurate in their judgments of how many kcals high ED food have (above 1.5 kcal/g). 
  • Children show a linear relationship between food preference and energy density. 
  • Over a five day period a spontaneous decrease or increase in kcals with ad-lib intake of low or high ED foods in children
  • RCTs generally show better weight loss and weight maintenance and less hunger with lower energy density diets. Not the end all be all, but makes a lot of mechanistic sense especially for weight regain. 
  • Low ED pre-loads are a viable strategy to try while dieting. 

We also discuss confounders of food volume and how they matter in research, but not so much in real life

  • Nutrient Density/Diet Quality
  • Eating time
  • Water content
  • Fiber
  • Sugar
  • Fat

Does this food volume adaptation potentially go hypothetically go both ways?!

  • If you increase your food volume and do you now eat more high energy dense food?

Food volume, food quality, and weight gain

  • Skeleton of high quality meals of real food and then use higher ED foods to meet increased kcal needs.
