No, but if you have a considerable pubis and belly, it can look bigger as you lose weight, and if you're extremely heavy, you actually CAN gain some length. It isn't really getting bigger, though.
It may not look bigger, but I'm pretty sure that if you're heavier & it looks a bit smaller than it is, it may start to look like more of it's actual size once you lose weight. I'm kind of speaking from experience. I've never been fat, but I will admit I was chubby, & over the past year, after losing 16 lbs, I've noticed that it does look bigger. But hey, it's different for everybody, I suppose. I'm still growing, afterall.
Research shows that an 80 kilo (176) pound man has a penis that weighs 700 grams when erect (about a pound and a third). Lose 10 kilos (22 pounds) and that increases by 13%. So, logically, if you lose half your body weight, you'll start tripping over it. And yes, I only weigh 14 kilos. nb this is a joke.
I see no logical explanation as to why your penis would grow while losing weight, except for the optical illusion that it gets bigger in proportion to your body. However, losing weight (if you are obese) is a good idea, and at the same time you CAN get a bigger healthier penis too. There are several natural ways to enlarge your penis, one is fun the other is practical. You could exercise it by pulling on it and massaging it to get a better flow of blood into it, but if you feel embarassed, or feel you won't do it regularly enough (and you'd need to do it a lot, there is another penis enlargement method. You can buy a ring or bracelet kind of thing which is designed to be worn for a long hours under your clothes, and it acts like a bloodflow enhancer, blood activizer and many other things that DO contribute to a larger penis. So if you want to connect your health enhancement diet with some male enhancement, I suggest this is the way to go. Losing weight but at the same time taking pills or feeling less confident because of the size of your rocket will not contribute to your overall wellbeing.
I think the penis basically extends about the same distance from your pelvis no matter what your weight is. Men gain weight mostly in their bellies, but you also gain some body fat around your pelvis when you gain weight. Thus the penis does not extend out in front of the skin around you pelvis as far, because there is a layer of fat behind the skin. Essentially the penis is the same length, but part of it is covered in fat. If you lose that fat it will extend a little farther in front of your skin. I weigh about 50 pounds more than I did when I got married 21 years ago (I was skinny at the time, and about 25 pounds overweight now) and my penis is about 1/2" shorter than it was before I gained the weight.
The penis itself does not have much fat, if any, and would, therefore, be larger in proportion to the rest of the body as bodily weight is lost. Furthermore, as the length of the penis is measured from the pubic bone, although this, in itself would be no different, the reduction of fat surrounding the pubis would make it look longer.
its SEEMS to get larger because the fat "hiding" it goes away. technically no it doesn't. however losing weight you may "uncover" the parts of it trapped insight that fatty fat fat
