Water Fast Weight Loss Formula:
Water fasting is a practice where an individual abstains from consuming food and drinks only water for a specified period. It is a popular method for weight loss, believed to help detoxify the body, boost metabolism, and improve overall health.
During a water fast, the body is deprived of calories, causing it to turn to stored energy reserves, primarily fat, for fuel. This metabolic process, known as ketosis, can lead to weight loss as the body burns fat for energy. Additionally, water fasting may reduce insulin levels, increase levels of fat-burning hormones, and potentially speed up the loss of water weight, particularly at the start of the fast.
The rate of weight loss during a water fast varies depending on factors such as body composition, metabolism, activity level, and fasting duration. However, it’s crucial to understand that water fasting may not be suitable for everyone and should be done under supervision, especially for extended periods.
The weight loss formula for water fasting involves body mass reduction per calorie deficit over time, with key factors being calorie consumption and fasting duration.
Weight loss, W(g) in grams is equal to the product of Daily Calorie consumption, DC in kcal/day and Duration, D in days, divided by 3,500.
Weight loss, W(g) = DC * D / 3500
W(g) = weight loss in grams, g.
DC = daily calorie consumption in kcal per day.
D = duration in days.
Water Fast Weight Loss Calculation:
1.A person has a daily calorie consumption of 2,000 kcal/day and plans to do a water fast for 3 days. Calculate the expected weight loss in grams.
Given: DC = 2000kcal/day, D = 3days.
Weight loss, W(g) = DC * D / 3500
W(g) = 2000 * 3 / 3500
W(g) = 1.71428g.
2.If a person consumes 1,800 kcal/day and aims to lose 2,000 grams during a water fast, calculate how many days they need to fast.
Given: DC = 1800kcal/day, W(g) = 2000g.
Weight loss, W(g) = DC * D / 3500
D = W(g) * 3500 / DC
D = 2000 * 3500 / 1800
D = 3.89days.
