Não, Clark Kent não tem um problema de peso. Mas ele deveria. Superman tem sido retratado desde o final dos anos sessenta como tendo as proporções de altura e peso de um macho humano normal, apesar de sua força sobre-humana.
A DC Comics não se preocupou em abordar essa questão com o Superman em nenhuma das versões anteriores do Man of Steel. Ele quase sempre foi listado em torno de 6 a 6,5 metros de altura, pesando aproximadamente 225 - 250 libras, às vezes um pouco mais.

Sua força, já que a Idade de Ouro não dependeu de sua chegada de um planeta de gravidade pesada, e em muitas iterações, Krypton nem é considerado um mundo de gravidade pesada. Nesses casos, a força sobre-humana do Super-Homem é estritamente um produto de sua infusão / conversão de energia com energia solar em força sobre-humana e seus outros poderes.

Não, isso não foi retratado de forma consistente; particularmente durante os períodos em que Kal-el pode perder seus poderes ou durante o período como Superman Blue / Red, quando ele não tinha força sobre-humana.

No Universo Marvel, por exemplo, os Asgardianos para compensar parcialmente a sua força sobre-humana (mesmo um Asgardiano normal pode levantar dez toneladas) têm três vezes a densidade óssea, muscular e global dos tecidos humanos normais. Sim, no caso de alguns Asgardianos eles têm uma força ainda maior, mas nós assumimos que existe um componente mágico para aqueles que estão levantando muito além disso.
Cientificamente falando, Clark Kent, de fato, todos os criptonianos devem pesar, pelo menos um pouco mais, e ter um peso molecular maior do que os humanos normais. Vindo de um mundo que era supostamente significativamente maior, eles teriam que ter sido muito mais strongs para manter sua aparência humana.
Nada disso faz sentido estrito e com múltiplas versões de inconsistência de Krypton, Superman, escritor e editor, não é de se surpreender que os detalhes tenham sido perdidos ou encobertos. Basta olhar para as modificações para o planeta Krypton ao longo das décadas:
Krypton and its history has been altered to a great extent from its previous versions. In the post-Crisis Krypton, sexual reproduction was considered obscene, and thus, all children were conceived in birthing matrices. After Infinite Crisis, this was taken out of Kryptonian culture.
Also in post-Crisis Krypton, this planet was located in a solar system within the Milky Way galaxy close enough that the radiation from the explosion (traveling only at light speed) was able to reach Earth (Action #600).
But after Superman: Birthright it was suggested that the planet Krypton was from an entirely different galaxy. In current continuity however, Krypton has been revised back to its previous position and is confirmed to be in the sector of space that borders that of Earth.
The Green Lanterns have dubbed Krypton's sector of space 2813 (Earth's being 2814) and was under the protection of Green Lantern Tomar-Re when it was destroyed. Another element to the previous version of Krypton was that all Kryptonians were unable to leave their planet or they would die instantly. This was a result of the Eradicator altering the genetic codes of Kryptonians to keep them planet-bound after a group of them left Krypton to explore and colonize other planets. The Eradicator punished these Kryptonians by altering their genetic codes to be vulnerable to lead, which resulted in the Daxamites.
Originally, Jor-El had a serum that he invented that would allow a Kryptonian to leave the planet safely; which he gave to his son Kal-El upon leaving for Earth. This was created to maintain the rule of Superman being the only Kryptonian survivor which was the theme of the post-Crisis Superman mythos.
This was reversed after 2003 when it was revealed that Superboy (Conner Kent) was half Kryptonian and then in 2004 when Supergirl (Kara Zor-El) arrived on Earth. The Eradicator did not place the planet-bound restrictions on the Krypton of the current DC universe but it still seems to be responsible for the Daxamites' lead vulnerability.
The Krypton of the current continuity was at one time an expanding empire that conquered other planets for years but was dismantled after the Kryptonian high council decided that their methods were too aggressive. The city of Kandor had a lunar city named after the planet bound city and when the lunar colony was destroyed, Brainiac kidnapped the real Kandor.
Other multi-ethnic versions of Kryptonians that resemble African-Americans and Asians also make an appearance in current continuity. Though previously, "black" Kryptonians were mainly confined within the Kryptonian continent of Vathlo Island. In the New Earth continuity, dark-skinned Kryptonians are more integrated into Kryptonian society than they were in the silver and pre-modern age DC universe. The other racially diverse people of Krypton came from a continent called Twenx. --Wikipedia > Krypton
