One can loose 15 lb in a month but that is the unhealthy way. Thebest way is to loose 1lbto 2lb per week doing so will help you not gain the weight back and also if you want to loose weight a mixture of cardio and weight traning can do the trick and remember to also give your body a rest

It is not always unhealthy to lose 15 pounds in a month. It really depends on how big you are. This is better thought of as 1% per week.

There are plenty of people on the forum who weigh over 300 pounds and it would be perfectly healthy for them to lose 15 pounds over the course of the average month.

The notion of 1 to 2 pounds per week only came about because quite a lot of people weigh between 100 and 200 pounds.

Oh and another thing one does not turn fat in to muscle. The muscle is hidden under the fat untill it is burned off compleatly then you can see the muscle. To get the muscle more riped or bigger one must of course rip the muscle tissue by doing weights push ups nd tuff like that then you need to rest your body. While your body is resting your riped muscle will repair its self with a new set of muscles that's why one feels sore after a work out exuse my typing and speeling I'm on my phone

Well omega I respect your opinion a person that is 300 pounds can loose the 15lbs in one month the healthy way but only with a doctor supervision the doctor will put him or her in the proper diet the proper excerise routine ect. I advise everyone before doing anything toconsult with your doctor because sometimes it may be more then just being obese it can do with your thyrode or other problems.

i concur 100%

Most GPs have no idea of what constitutes a healthy calorie level for a seriously morbidly obese person.

You would not believe the amount of people still being told by their doctors that 1000 to 1200 calories were an appropriate level for weight loss.

A GP only told me this morning that he had never met anyone who had lost as much weight as myself - and he has been a registered doctor since 1986. We have to remember that the G in GP stands for "general" and they do not have specific expertise and should not be expected to have this in any subject.

Most such people would be far better off if they researched the subject for themselves.

I totally agree with Omega on the doctor thing.
Yes, some people should check things over with their doctor.
But generally, you learn so much more just looking things up yourself! Maybe that's just me, but I haven't had the best experiences with GP's who simply give me a prescription before even fully listening to my symptoms and who shoo me away before I can ask questions.
Also, for TOPS (Taking Off Pounds Sensibly) they require you get a goal weight from your doctor. It must be written on a piece of paper and signed.
The doctors just use the BMI to figure this out!!! I've looked at the BMI and I know what range I can be within, it's not that hard to use. I also know that with such a huge range I will stop at a weight I am happy with and healthy at.
Does anyone else find it odd that we use the BMI to determine weight?
I guess it's fine when used as a guideline.

BMI isn't always the best tool.. maybe if you're just starting out and are over weight.. but in the end you should use body fat % to determine your goal weight.

My BMI is odd because of all the loose skin that I carry. That all adds to the weight part of the equation but will never get lost through natural means. The only way that will go down at this stage is by surgery. I am actually slimmer than my BMI would imply.

My keep fit teacher told me that her BMI puts her in the "overweight" category - and I can tell you that she certainly does not carry any extra fat on her...

In all honesty - eating a proper balanced diet which hits all nutritional targets, recording this fact using a tool like fitday and doing an appropriate level of exercise for your size would be good advice for anyone. If you have problems losing weight using this method - then most people would be scurrying to their GP in order to investigate the possibility of a medical issue being involved. The above methods having been tried would only aid in any investigation.

A lot of people that do have medical issues coming into play are not given appropriate dietary advice by their GP. They often discover it by their own research.

I am a PCOS lady and was never told to watch my starchy carbs (compared to a normal person) by my GP. I discovered it in my own research. Only last week I was in contact with a PCOS lady on another forum who was amazed when I passed on the information. She had been having no success - but she had been on a calorie counted sandwich diet where she was eating sandwiches all of the time...
