Losing weight is fun and the faster it happens the happier most people are. Naturally, the kind of weight loss you can expect depends on the kind of time you can give to it. Let's say you want to shed the most pounds in a month. How much weight can you really lose in one month if you want to do it in a healthy way?
Before, I want to emphasize that you shouldn't judge your weight loss progress by the number of pounds you shed alone. The kind of weight loss you can achieve depends on many factors including how fat you really are in the first place. So, even if you lose just 5 lbs in a month, don't feel bad. It's perfectly fine.
That being said, you can lose to 20 pounds in a month without it being too drastic, as long as this doesn't make you too thin. However, some people manage to lose 30 pounds and still maintain their health. It's more about how you shed the pounds than the number you manage to melt away.
As long as you do it right, I wouldn't worry too much about losing weight. Just make sure you actually feel better when you lose weight and don't begin to feel lousy.
For instance, if you begin to feel weak, tired all the time, have headaches, or you're constantly hungry, you may be doing something that's not healthy and you should change your routine to a more healthy one to make sure you don't cause yourself harm.
If you workout like crazy and begin to experience pain, frequent cramps, or can't seem to build muscle tissue, you may be working out too much and should cut down.
If your weight loss doesn't make you feel better then it's probably not good for you and may be extreme and unhealthy.
Don't push for anything over 20 pounds as a general rule. Even if you lose 10 pounds in one month you should be very satisfied with yourself.
