How to follow a diet successfully.

Be determined and motivated .
Ask yourself why you want to reduce your body fat, and how important it is to you. Less body fat makes you more beautiful and healthy.
Change your mindset: stop thinking about food as an item of pleasure, consider its nutritional value as a means to feed your body, to get slim, and to stay healthy.
Make sports a part of your life. Do your exercises every week on the same days and the same time.
Allow yourself one junk day per week, on which you can eat whatever you want, without going above your daily calorie intake. The other 6 days you follow your diet very strictly. The junk day is very important from a psychological standpoint.
Plan every morning when, what and how much you will eat that day.
Eat every day around the same time.
Don't make eating a big social event. Eat alone or with your family.
Don't let other people decide or influence when, what, and how much you eat. You should be in control of your diet yourself.
Don't buy or prepare more food than you are planning to eat. It's harder to stop eating when the table is still full of food.
Leave the table as soon as you finish eating.

Is very important to be yourself.
