Can low calorie diets keep you tired?

Today I was exhausted, and than I had dinner and my energy was restored

Yes.
Your blood sugar can drop, maybe if you aren't doing so already take a multi vitamin every day.
Another thing to try is eat the same amount, but eat more often, like every 2 hours.
Split your meals up into smaller portions.
It will help eliminate the peaks and valleys.
Like some diabetes do to help keep their blood sugar in check.
And make sure you are eating a balanced diet.

Yes. If you don't eat enough and/or get the right nutrients you will feel tired all the time.

I hate diets. Nutrition that is consistant ans that you enjoy eating is the best. Find quality foods that you can eat the rest of your life.

Calories are units of energy your body uses to function. When you don't eat enough calories, you're likely to feel tired most of the time. The number of calories needed for these basic functions within a 24-hour period is referred to as your resting metabolic rate.
