La fórmula, paso a paso
- Base: peso en kg x 0.033 L.
- Actividad: sumamos más líquido según el movimiento diario.
- Clima: ajustamos a la baja en fresco y al alza con calor.
- Etapa de vida y GLP-1: aplicamos suelos conservadores.
El resultado es una meta diaria para beber. La comida suele aportar una parte adicional de agua, pero mantenemos el titular centrado en lo que realmente bebes.
| Peso | Base | Meta aprox. | Onzas |
|---|---|---|---|
| 60 kg (132 lb) | 2 L | 2.3 L | 77 oz |
| 70 kg (154 lb) | 2.3 L | 2.6 L | 88 oz |
| 80 kg (176 lb) | 2.6 L | 2.9 L | 99 oz |
| 90 kg (198 lb) | 3 L | 3.3 L | 111 oz |

- 4.UK NHS (Eatwell Guide) — Suggests about 6–8 glasses (roughly 1.5–2 L) of fluid a day — water, lower-fat milk, tea and coffee all count toward the total.
