From a diet history you estimate that Harry is consuming ~13 000kJ and he wants to reduce his energy intake to lose weight. He is consuming ~40% of his energy from fat (150g), ~40 % of energy from carbohydrate (300g) and ~20% of energy from protein (150g). Which strategy would be the most effective in reducing his energy intake?Group of answer choicesReduce his carbohydrate intake by 75gChange his AMDR to - 15% of his energy from fat (30g), 50% of energy from carbohydrate (200g) and 35 % of energy from protein (140g) (low fat, high protein, moderate carb)Reduce his fat intake by 60gChange his AMDR to - 25% of his energy from fat (50g), 25 % of energy from carbohydrate (100g) and 50 % of energy from protein (200g) (low carb, high protein, moderate fat )
Question

He is consuming ~40% of his energy from fat (150g), ~40 % of energy from carbohydrate (300g) and ~20% of energy from protein (150g). Which strategy would be the most effective in reducing his energy intake?Group of answer choicesReduce his carbohydrate intake by 75gChange his AMDR to - 15% of his energy from fat (30g), 50% of energy from carbohydrate (200g) and 35 % of energy from protein (140g) (low fat, high protein, moderate carb)Reduce his fat intake by 60gChange his AMDR to - 25% of his energy from fat (50g), 25 % of energy from carbohydrate (100g) and 50 % of energy from protein (200g) (low carb, high protein, moderate fat )
Solution
Para determinar cuál estrategia sería la más efectiva para reducir la ingesta de energía de Harry, primero debemos calcular la cantidad de energía que proviene de cada macronutriente en su dieta actual.
-
Calcular la energía actual de cada macronutriente:
- Grasa: 150g * 37.7 kJ/g = 5,655 kJ
- Carbohidratos: 300g * 16.7 kJ/g = 5,010 kJ
- Proteína: 150g * 16.7 kJ/g = 2,505 kJ
Total: 5,655 kJ (grasa) + 5,010 kJ (carbohidratos) + 2,505 kJ (proteína) = 13,170 kJ
Esto es aproximadamente igual a la estimación inicial de 13,000 kJ.
-
Evaluar cada estrategia:
- Reducir su ingesta de carbohidratos en 75g:
- Nueva ingesta de carbohidratos: 300g - 75g = 225g
- Energía de carbohidratos: 225g * 16.7 kJ/g = 3,757.5 kJ
- Energía total:
