This question is a popular one in the diet-health-workout community. Some say once every two weeks, some say once a week, some once a day, some weigh themselves even more often than that.
So: how often should you?
Well, I’m going to disappoint you: there is no only truth here. It depends on a lot things.
1. Can you handle fluctuations?
2. Why every day is good?
Although there are cons to weighing yourself every day / more than once a week, there are pros. Now imagine that: you weighed yourself last Saturday, got a number. Now this Saturday you weigh yourself again and BAM! – 500 grams heavier. You might freak out and think that something is wrong with your diet, exercise or attitude. But actually: if you had weighed yourself Thursday, you would have been 500 grams lighter than last Saturday and actually gained a kilo of water weight during Thursday and Friday. This is possible. So sometimes it’s quite useful to weigh youself every day.
So it is really up to you. If you can handle fluctuations, go ahead and weigh yourself every day. If you don’t, don’t weigh yourself every day. For me twice a week would be best but I still break that rule. The only thing I’m sure about is that more than once a day is excessive, I just don’t see the point in that.
In conclusion: to each its own.
