The amount varies depending on your weight and activity. For sedentary people: 0.8-1.0 g per kg of body weight. For athletes or those looking to gain muscle: 1.6-2.2 g per kg. The macronutrient calculator gives you a personalized figure.
The best time is at the end of a complete sleep cycle (multiples of 90 minutes from when you fall asleep). The sleep cycle calculator shows you the optimal times to wake up without grogginess.
In regular drinkers with moderate doses (1-3 cups/day), coffee does not produce a net hydration deficit. However, at high doses (>400 mg) or in occasional drinkers, additional water intake is justified. The caffeine hydration calculator helps you determine how much extra water you need.
If symptoms interfere with your quality of life, if you have bleeding after menopause, or if you're under 45 with menopausal symptoms, consult a healthcare professional. The menopause calculator is an educational tool, not a diagnosis.
The carbon footprint calculator shows you which areas have the greatest impact. Some effective changes: reduce meat consumption, choose public transport or cycling, improve home energy efficiency, and reduce single-use product consumption.
