The real question is whether you can cut 1,750 calories out of your daily diet and still consume enough calories to keep your energy levels up and your nutrient intake sufficient. Take your daily maintenance calories and subtract 1,750 to see how many calories you can consume each day to lose 15 pounds in a month.
If it puts you below 1,200 calories as a woman or 1,800 as a man, you’ll need to reconsider your goal.
If your calorie level after you subtract the 1,750 is below those minimum numbers, then you should not lose weight at the rate of 15 pounds in one month. Lower calorie levels don’t provide enough food for you to get optimal amounts of nutrients. Plus, when you consume too few calories, your metabolism slows to a crawl, which ruins your weight loss efforts.
