Metabolism boosting foods are discussed below.
Losing 10 lbs a month is a good and safe target. Any faster weight loss is likely to be temporary only and in most cases you regain it all.

You can always eat negative calorie foods for weight loss and below is a list of negative calorie foods that will boost your metabolism.

These foods don't actually have negative calories but when you eat these foods raw or slightly cooked your body burns more calories digesting and processing them than what is in the food itself.
For a healthy weight loss add some of these foods to your diet each day. Most of them are full of healthy nutrients such as fiber, antioxidants and enzymes as well as vitamins and minerals.
