1000 Kalorilik Diyet is a free lifestyle application for Android developed by İnovatif Design. The app provides a three-day diet plan and weight loss exercises that can be easily done at home. The program claims that by following the diet plan, doing a 40-minute walk, and exercising for 30 minutes, one can achieve the best possible results. The app also claims that by following the 1000 calorie diet plan, one can lose up to 1 kg of weight per week.

Based on the app's claim, if your basal metabolic rate is 2000 calories, you can lose up to 1 kg of fat per week by following the 1000 calorie diet plan. If you have more weight to lose, you can lose up to 2 kg by factoring in the loss of water weight when losing 1 kg of fat. However, it is important to note that the app advises not to follow the diet plan for an extended period and to consult a doctor before starting the program, especially if you have any underlying health conditions.
