On the diet for X amount of time and haven’t lost any noticeable weight.

I’ve been on the diet for X amount of time and haven’t lost any noticeable weight. Why?

First off, do not concern yourself with your weight. In fact, I would refrain from weighing yourself altogether. Scale weight has very little to do with overall health and can be both frustrating and misleading.

If you want to track your progress on the diet, you can buy a scale that will also calculate your bodyfat %. This will tell you the percentage of body weight that comes from body fat. This is a far more effective way to measure progress.

You may be losing fat and gaining muscle at the same time, (even if you don't exercise), in which case your scale weight won't change at all.

However, your body fat percentage will go down and that is what is important. In the states you can get a bodyfat scale from any home appliance store for anywhere between 30 and 70 USD. The percentage itself won't always be completely accurate but as long as you use it at the same time of day (a good time is right after waking, before eating anything. And I'd limit it to once a week) it will be consistent.

You should not be concerned with the number itself, just the change that happens as you continue on the program.
