1000-LB. SISTERS star Tammy Slaton has slipped back into her old habits after her split from husband Caleb Willingham.
A source exclusively told The U.S. Sun that Tammy, 36, has regressed back to her dangerous pre-rehab lifestyle of fast-food runs and smoking.
The source claimed: "Tammy is back to her old ways. She isn't paying attention to her diet, she is vaping, eating McDonald's regularly, and generally is not taking care of herself.
"There doesn't seem to be a lot of support from family, because they don't appear to be particularly strict with themselves, let alone each other."
Tammy shed 300 pounds after spending 14 months in treatment in an Ohio facility where she abstained from drinking alcohol, smoking, and eating unhealthy foods.
Last month in photos exclusively revealed by The U.S. Sun, Tammy was seen vaping while riding an electric scooter in a Walmart parking lot in Kentucky.

Tammy returned to her life in Kentucky in February of this year, but her estranged husband, Caleb, 40, is still at the Ohio facility.
TAMMY AND CALEB SPLIT
An insider previously told The U.S. Sun that Tammy and her husband Caleb are officially separated and that she is in the process of filing for divorce.
"Tammy has her legal team lined up and is ready to file for divorce," the source close to the 1000-Lb. Sisters star claimed.
"They split up because Caleb hasn't been following his diet in rehab," the insider alleged, adding: "He has gained 30 lbs and hasn't been working his program."
"They got into a big fight over it and he told her he wanted a divorce, but then he tried to backtrack," the insider claimed.
Though Caleb tried to keep their marriage together after their falling out, it was too late.
"Tammy's sisters Amy and Amanda were already encouraging her to just move on."
The family insider said they believed that Tammy's decision to end it with Caleb was the right thing for her.
"They got married after just knowing each other over the course of weeks, in rehab, and he's still there.
"She didn't want a long-distance relationship and certainly isn't able to care for someone else at this point in her recovery," the source claimed.
Tammy's rep and Caleb did not respond to requests for comment.
WHERE'S CALEB?
Last month, fans questioned the TV personality on the whereabouts of Caleb, 39, after she posted a video to duet a crystal shop on TikTok to help promote a small business.
In the video, Tammy didn't say anything but instead just looked into the camera.
She had a fake eyelash filter on while donning a black shirt and a sun necklace.
In the comment section of the video, fans couldn't help but ask the TV star about her husband and the current status of their relationship.
One person asked: "What happened to ya husband?"
Another fan questioned: "How have you and Caleb been?" while a third queried, "How are you and your husband doing?"
