Dear Possible To Lose 50 Pounds In 3 Months?,


It may be possible to lose 55+ pounds in 3 months, but that doesn’t mean it is the healthy thing to do. FX has two major concerns about losing so much weight in such a short period of time:

The first concern involves possible health risks. One example of a health problem that can occur in people who lose weight too quickly is the occurrence of gallstones, hardened deposits of fluid that can form in your gallbladder. Other medical issues associated with rapid weight loss can include dehydration, malnutrition, and electrolyte imbalances. In addition, some people may experience headaches, irritability, fatigue, dizziness, constipation, menstrual irregularities, hair loss and muscle loss as side effects of rapid weight loss.

The second concern is that if you use some kind of crash diet to lose that much weight in 3 months, you will be left knowing only two lifestyles in terms of eating. The lifestyle that lead you to be overweight, and the lifestyle that allowed for rapid weight loss. So FX is concerned about where this will leave you once you reach your goal weight. You will not have developed the skills that will allow you to maintain your weight in a healthy way, so there is a good chance you may gain a lot of the weight right back after you reach your goal weight and stop whatever diet you used to get there.


All that said, FX thinks that it is wonderful that you want to take steps to get your weight into a healthier range. There are certainly health risks with being overweight (such as increased risk for heart disease, Type 2 diabetes, high blood pressure, high cholesterol, and respiratory problems), so it is in your best interest to lose weight if you are overweight. To do this in a healthy way, consider the following:

·         Meet with your doctor to discuss a good goal weight for you. You said in your question that you “need” to weigh between 115 and 120 pounds, but FX does not know you height and can’t give any input on whether this is a healthy weight range for you or too low.

·         Once you and your doctor come up with a healthy goal weight, find out from your doctor what a reasonable amount of time is to give yourself to lose this weight. The time might be longer than 3 months, but try to be patient and know that with each week and each month you will be getting closer and closer to your goal (even if you are not completely there by graduation).

·         Speak with your doctor, a nutritionist, and even a personal trainer about the important lifestyle changes you will need to make as far as diet and exercise that will help you lose weight and, later on, maintain your goal weight.
