I have been working in the fitness industry for a long time and I have found that there are literally hundreds of people who weigh themselves every single morning.
Although this is a great habit to get into, there are 2 negative aspects associated with weighing yourself each morning and if you are aware of these you will be able to maintain your weight a lot easier.
The first problem many people have is yo-yo dieting. Many people wake up and weigh themselves first thing in the morning, if they are unusually light they tend to choose unhealthy foods all day as a reward for being light that morning. Then a few days later these people weigh themselves again and may be slightly heavy resulting in them either skipping a few meals or hopefully choosing healthy food options. If this continues to happen on a weekly basis then the person’s weight will yo-yo up and down. This is simply due to the fact that the person’s diet is all over the place and they are not eating a balanced diet.
Therefore, it is important to include healthy food options on an everyday basis opposed to a meal to meal basis.
The other problem with weighing yourself in the morning is the simple fact that you are dehydrated. The reading you are getting in the morning is a dehydrated reading because you probably have not had anything to drink all night. It is important to take this into consideration if you are recording your weight in a diary etc.
I believe the best thing to do is to get your skin fold checked by a qualified professional once every month. A skin fold reading is done using a set of calipers. The fitness professional will pinch a layer of fat at seven sites around the body. They then record the numbers and tell you how much body fat you have. Although results vary depending on who does your test over time you will be able to see an average result.
If you do not have access to someone who knows how to measure your skin folds then simply look at how your clothes fit. If you have gone down a few belt sizes or your work shirts are a bit looser than they usually are then you know you have lost (or put on) some weight.
In the end, a healthy lifestyle, good eating habits and consistent physical activity will help keep you fit and healthy forgiving life your best shot.
