You can and sometimes it's acceptable based on how overweight a person may be. The more overweight you are, the more aggressive you can lose pounds but that doesn't mean you should try to lose weight fast. Based on being able to maintain weight loss, the current evidence-based recommendation is to lose 1-2 pounds per week. More than this leaves you with a higher probability of weight regain. Slow weight loss allows the body to adjust to the necessary weight reduction calorie deficit. The larger the deficit, the faster the weight loss and the more difficult it is for the body to maintain and adjust to. In other words, your appetite is less controllable as time goes by, and daily activities become harder to maintain because of lack of energy while feeling hungry. That said, dotFIT does recognize the occasional need for faster weight loss so the program is set up to deliver the proper protocol. When choosing the weight Loss goal in the online program, it will allow you to be as aggressive as necessary up to a point of not being safe based on the calorie intake target being too low to supply necessary nutrition. The goal of Weight Loss and Performance will not allow aggressive weight loss because it would compromise athletic performance. Also, keep in mind the faster the weight loss, the more muscle tissue lost - unless you heavily supplement the diet like bodybuilders who have to reach very low levels of body fat.
