Okay this LoRA is available only here, please DO NOT REPOST! I made it due to a request by a friend, and at the end it works better than I expected. It can lazily make men, anthroes and even woman to get a beer belly. Warning though! It does generate NSFW, use at your own risk.
TRIGGER-WORDS:
Although this is a LoCON, hence depending on no trigger words might be needed. The trick has more to do with the weight... but,
for males (anthroes included) DILF, 1man... if you want him tough you can add "thick arms", although on semi-realistic and anime models it will probably just tick by default.
for exposed belly, then add "belly" to make sure.
if you want him really bloated, add "fat".
UPDATE:
I brought here his real V.1 - and now available only here.
Check the samples above, I was very honest on the images, and the maximum it has is Ultrasharp at 10 with fix at 0.3. They were made here ON SITE and ON BASE SD 1.5 and on REAL CARTOON (awesome model!) If SD1.5 can do, all the others should. Hence, I recommend using any RealCartoon as the base model, but he works with realistic too, although please do check the settings I used on the sample images above on basic base mode SD 1.5, so that you don't get him burnt.
HE DOES HAVE ISSUES with his hands though! The thing is that many of his pics were with him with hands in the pockets. On different poses or clothings one hand might have fingers cropped. I think that adding "unclenched" in the positive prompt sorts it out, unless you want him holding a prop, but in any case, unclenched in positive or clenched/clasped in the nevagitve.
It won't be the case I guess... because our focus here is not the face... but you can use him inside any facial extension, such as ADetailer or any other on Comfy, if you prefer.
Or just add that light-control slider LoRA and his face will shine.
Enjoy!
