There really is no simple answer to this, but we'll start by giving a marker for healthy weight loss.

*Important note before proceeding: while it is possible to lose more weight per week than the amount described below, it is best to consult with a certified medical practitioner and/or certified trainer in person before attempting to do so. Even those familiar with the process of losing larger amounts of weight in a short period of time will recommend only doing so under the supervision of trained professionals. This is for your safety.

For healthy weight loss, according to the Mayo Clinic, it's best to aim for losing 1 to 2 pounds (0.5 to 1 kilogram) a week. This is a commonly accepted benchmark for weekly weight loss across many, if not most, top certified medical institutions. Generally to lose 1 to 2 pounds a week, you need to burn 500 to 1,000 calories more than you consume each day, through a lower calorie diet and regular physical activity.
Depending on your weight, 5 percent of your current weight may be a realistic goal… If you're 180 pounds (82 kilograms), that's 9 pounds (4 kilograms).

When you're setting goals, think about both process and outcome goals. “Walk every day for 30 minutes” is an example of a process goal. “Lose 10 pounds” is an example of an outcome goal. It isn't essential that you have an outcome goal, but you should set process goals because changing your habits is a key to weight loss.

In light of the above, we would not be able to determine each user’s individual results, due to the number of factors involved, such as their own personal physiology, level of commitment to diet and fitness regimens, hereditary factors, and so on. And we say this in consideration of whether or not our products are being implemented in any given person's weight loss efforts.
