If the energy you spend is higher than the energy you receive, you start to lose weight. Well, how healthy is this weight loss? Are you really doing the right diet? What do you need to do for healthy weight loss? 
What you need to do to accelerate metabolism and a healthy weight loss; 
*Feed without skipping meals. Consume 3 main meals, 3 snacks each day. Making regular snacks gives you a feeling of fullness. Especially at snacks you can choose dry fruit, raw nuts, raw almonds or breadcrumbs.
*Make sure you do not spend more than 3 hours between your meals. In this way, your blood sugar will be balanced and your metabolism will accelerate.
*Take a 30 minute walk every day. So you can accelerate your metabolism by increasing lean muscle mass.
*Do not start the day without breakfast. The most important meal for a healthy weight loss is the breakfast. Different breakfasts allow your metabolism to accelerate better. For this reason, make changes to your breakfast every day. 
*If you are predominantly fed simple carbohydrates and consume less protein, you will slow metabolism. You can speed up your metabolism by consuming a protein source (milk, yogurt, eggs, meat, chicken, fish, etc.) every other day.
*Tea, coffee, and sodas consumed in excess in the day do not replace water and increase water loss. For this reason, be careful to consume 2-2.5 lt water per day.
*Consuming 2 cups of green tea a day will help you lose weight.
If you want to lose weight in a healthy way, it will be enough to give 4-5 pounds a month. Remember, quick weight loss means you get your weight back quickly.
