La formule, étape par étape
- Base : poids en kg x 0.033 L.
- Activité : nous ajoutons du liquide pour le mouvement quotidien et la transpiration.
- Climat : nous baissons par temps frais et montons par forte chaleur.
- Étape de vie et GLP-1 : nous appliquons des planchers prudents.
Le résultat est un objectif quotidien de boisson. L'alimentation apporte souvent de l'eau en plus, mais nous gardons le chiffre principal centré sur ce que vous buvez.
| Poids | Base | Objectif approx. | Onces |
|---|---|---|---|
| 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 |
