Drink only water for 7 days
Post pictures of your meals with water every day or write your impressions!
A perfect detox week
Some people forget that a good part of the calories we consume every day are coming from drinks, sodas, beers, packed juices, coffees or tees with sugar, etc... Avoid all those for a week and you will see the benefits
The worst part of this challenge is to go out with friends and drink only water in your favourite bar, but ey, it is just for a week.
