You can feel fine and still be eating too little (for nutrition, for muscle preservation, for maintenance of immune system, skin repair, etc., etc.). Most of those things are not going to be an issue after just one week, especially if you have a lot of weight to lose, but will eventually become issues if you continue to under eat long-term.

You'll get better advice if you provide more information, such as your weight, your height, what your daily activity level is, how much you are exercising, how long you have been restricting your calories, how much you weight you have lost over that period, how many calories you are consuming, and how you are calculating the calories you consume (are you weighing your food)?

I sometimes talk to a nutritionist...She informs me that when we are in starvation mode (eating less calories) our bodies hold on to everything because it does not know what it will get next time. This gives you the feeling of being full ( That is my problem). So, what I need to do (is make sure I get the same amount of calories at each meal on a daily basis). For me, that's difficult. Can you believe it? Some people find it hard to eat less and I find it hard to eat more. How about you?

If that were true, people would never starve to death. There's no such thing as starvation mode.

You can bump up your calories by adding calorie-dense things like nuts and butter. You don't need to eat the same amount every meal. Your calories just need to be high enough when averaged over the course of the week.

As for hunger, sometimes I'm hungry and sometimes I'm not. I just eat more when I'm hungry and less when I'm not. Some people with weight problems don't have great hunger signals, especially when starting a new eating plan.
