Reasons for fluctuations in weight
Diet & Nutrition Expert Advice

Why does my weight fluctuate so much?

Being a dietician, I have been approached by many clients with a very curious question “why does the weight fluctuate throughout the day and why do we weigh less in the morning?” This question is more common when I typically tell them to check their weight and record it in the morning on empty stomach. But most of the people shirk it telling that we obviously weight less in mornings as we have starved whole night.

 

How often should you ideally step on the weighing scale?

During the phase of dieting, most of us have a tendency to weigh ourselves at every opportunity we get.  We tend to jump on our weighing scales at various times during the same day hoping the reading will be lower than the previous attempt.  This is more commonly done after an exercise class to see if we have instantly lost weight or after a meal. This seems silly to most of us but this is actually followed by most of people who are on weight loss diet regimes. I am sure you would agree to this, if you have religiously followed a weight loss regime! Ideally, you should fix one day of the week as “The Weight Check Day” !

I would like to share a few of my client experiences. I had a client who was too apprehensive about her weight, which most women take it by default! She checked her weight throughout the day and wondered so as to why the weight fluctuated every time she checked at different times and I am sure most of the weight watchers are looking for an answer to this! Isn’t it?

 

Let’s understand what are the possible reasons for weight fluctuations through the day and the reason behind weighing less in the morning. Here are the Top 3 facts which shed light on the same:

 

#1 Fact is, our body can fluctuate weight at any given time of the day.  Your gross weight will depend on the intake and out take the body undergoes daily. For instance, if one had lunch or used the washroom, both these conditions will lead to either a gain or a loss in the weight. The body’s level of hydration and perspiration also play a massive role in weight fluctuation.

#2 The second most obvious reason of the fluctuation in the weight and weighing less in the morning is, as the body is in a fasting state during the overnight sleep, there has been no consumption of food or fluids like water. Sleeping causes your body to rest without food or water for a long period of time. During the day we do a lot of physical activity and movements along with consumption of food as compared to the early morning hours where there’s absolutely no movement. Moreover, the food that you have consumed the previous day has been digested and most of the fluids have been absorbed during the night time when one is in the sleep state. This is the reason why your morning body weight is the most accurate body weight. Whereas, weighing at any other time of the day would simply be inaccurate due to undigested food, presence of digestive juices and the volume of unabsorbed fluid in the body.

 

#3 Another technical reason, is the amount of breaths we take at night which results in expelling carbon dioxide from the body. If you take the weight of carbon and compare it with the steady breaths one takes while sleeping, enough carbon is being exhaled to result in a few hundred grams of weight loss. This results in the visible weight loss observed in the early morning hours.

So now that you know, the next time you step on the weighing scale in the later part of the day don’t get demotivated if your weight is up by a few grams its pretty normal as far as you have followed the Diet regime advised by your health coach strictly! For the most accurate weight readings, always remember to step on the scale in the morning on empty stomach post clearing the bowels!
