Originally Answered: Is this healthy for a day, and what should I eat for dinner?
Honestly don't starve yourself. First of all, you need to ensure you're getting a balanced diet, that should include: lean meat or fish, whole grains, vegetables, and a healthy fat. Also, incorporating an exercise program will elevate your metabolism causing your body to burn more calories when at rest.
Long story short, don't get yourself into a dieter's routine of starving yourself for a while simply to get skinny or lose weight. You want to create and develop a lifestyle that's effective and easy to follow long term.
There are a lot of websites out there that can help you better understand how many calories you should be taking in each day and help put a meal plan together. Use it more to create a better understanding of what to eat and when.
