Thanks for reaching out about your guinea pigs. Typically a normal diet of hay, pellets and some vegetables will keep guinea pigs at their proper weight. concerns would be why are your pets thin? Dental disease, intestinal infections/parasites or metabolic concerns would be possibilities. Try to have a look at the incisors for any abnormal wear. If your guinea pigs appears sick, a veterinary visit is recommended.
Good luck.

Thanks for reaching out. The key is to decrease caloric intake. Pellets and vegetables are usually the culprits. A good quality hay, free choice, is difficult to gain weight with. Cut pellets and treats in half. Increase allowed exercise by allowing to roam (supervised) in a play area.
Good luck.
