Pediatric Weight Management

PWM: Protein Sparing Modified Fast Diets (2007)

Protein sparing modified fast diets to reduce pediatric overweight

• Intervention
  Are children on protein sparing modified fast diets less hungry than children on balanced macronutrient diets at the same level of energy intake?

  • Conclusion

    There is insufficient evidence to determine whether or not high-protein, low-carbohydrate, very-low-calorie diets provide a greater level of satiety for children in weight loss programs than balanced macronutrient diets at the same level of energy intake.

  Do protein sparing modified fast diets bring about greater weight loss in children than macronutrient balanced diets of the same level of energy intake?

  • Conclusion

    There is insufficient evidence to suggest that high-protein, low-carbohydrate, very-low-calorie diets (protein-sparing modified fast) result in greater long-term weight loss in children, compared to balanced macronutrient diets at the same calorie intake level.

  Do protein sparing modified fast diets preserve fat free body mass in children better than balanced macronutrient diets at the same level of energy intake?

  • Conclusion

    There is insufficient evidence to determine whether the short-term use of protein-sparing modified-fast diets preserve fat-free body mass in children any more or less effectively than balanced macronutrient diets at the same energy intake level.

  Does short term (no more than 20 weeks) use of protein sparing modified fast diets compromise fat free body mass in obese children?

  • Conclusion

    Several studies from a single program that measured body composition, using skin calipers, indicate that short-term use of PSMF for weight-loss in children, by and large, preserves fat-free body mass.

• Basic Research
  What evidence is there that short-term use of protein sparing modified fast diets for childhood weight loss may compromise the growth velocity of children?

  • Conclusion

    The evidence is too limited to determine the long-term the effects of the short-term use (less than 20 weeks) of a protein-sparing modified fast on children's linear growth.
