A low-calorie diet is based entirely on the number of daily calories that you consume. It is interesting to note that the USDA suggests a diet of 2000 calories a day to maintain your weight. So, to look at any sort of weight loss, you need to be eating less than 1900 calories a day.
Generally, the low-calorie diet reduces your calorie intake even further to somewhere between 1200 and 1500 calories a day. When you are on a low-calorie diet, it is not just a matter of reducing your calories; it is also a matter of ensuring that your diet remains well-balanced and provides your body with all its nutritional needs.
On a low-calorie diet, you need to consume only a certain number of calories per day while also ensuring you are eating meals filled with ingredients that provide the necessary nutrients that you need to stay healthy and active.
