Most people need around 1.5-2.5 litres of water per day, depending on your size and how active you are – more if you are very active or working out in heat. Of course 4-5 litres of water per day is not healthy, especially if you are also eating enough food! Cassey’s recommendations on this calendar are not unhealthy if you already drink a healthy amount of water – at most she’s recommending to drink 5 cups more than you would normally (1 US cup is – I think – about 250 ml or a quarter of a litre). I normally drink 2 litres of water a day, so following this calendar I would be drinking at most just over 3 litres. That’s not unhealthy.
Very happy with the results, I incorporated my own food tastes and mixed them with lots of veggies, fruit, kale, spinach and romaine lettuce, a huge salad everyday, no sugar, no white flower, no bread other than 100% wheat a couple times a week, cut out soda entirely. Greek yogurt every day, berries, only sweeten with honey. Old fashioned rolled oats, etc etc. I didn't use any of the recipes, too complicated, and costly too! I have lost 30 lbs from January 5th to now. I didn't exercise the first 2 months wanted to make sure I was losing from the food. I then started walking 2-5 miles 3 times a week - 15 pounds to go to my goal.
