How did I gain 6 pounds in one week?

Last Saturday(I weight myself at the same time every day) I weighed 135. Today I weighed in at 141lbs. I recently started lifting last week but I know that there's no way I added 6 pounds of muscle in 1 week. I also know there's no way I added 6 pounds of fat by going over my calorie limits by 21,000 calories. What could this sudden gain in weight be. If it helps I'm an 18 year old male, 5'4" tall and went from 135lbs(last week) to 141lbs. this week. Any help?

How to Lose Weight With Laser Treatments

Recommended Answer:

Because weight measurement is actually dependent on a lot of things other than fluctuations in body fat.I'd say the biggest error is changes in water content. However, how much you ate that day, depending onthe time of day is enough to change a few lbs in ONE day. It may very well be possible that the scale reads an increase of 6 lbs and you may have actually lost body fat in that time.Unless you can accurately measure body fat % and body weight by totally controlling all these variables I wouldn't read too much into this. You probably can get more information by pinching around your belly and looking in the mirror as to how you're fitness is doing.

• I'm not a doctor, but I think 21,000 more calories could do it
• A mixture of maybe you wore more clothing, had a full stomach, hadn't pooped in ages, just drunk lots of water, gained muscle.. grew taller?
• Knocked up?
• When you weigh yourself in the morning that is your actual weight. When ou weigh ourself in the afternoon or at night youll weigh a good 3 to 4 poinds heavier if you eat and take mass gainer. If our looking to be healthy about it, eat 4 to 5k calories a day, so 4 to 5 times a day. Strictly chckens, nuts and sweet potatoes. If your looking to take the not permanent, more expensive, quick way get some mass gainer and destroy your stomach and kidneys. In my opinion creatine and pre workouts are ok, but mass gainers are expensive fake food. If i was gonna be unhealthy about it i woul just juice instead of taking mass gainer. Hope that helped :)
• you might have grown taller suddenly or muscle might have stimulated to grow quickly.or there is one more thinggo look at yourself in the mirror if you are muscluar that means you have built muscle.or if you are looking fat, that means you have added fat.
• I'm pretty sure you mean 2,100 calories. Much of the weight is likely to be water.
