My power bill is lower thanks to tirzepatide.

Summary

Does tirzepatide change how warm or cold people feel and affect their AC or heating use?

Several users report that after starting tirzepatide and losing weight they now feel comfortable at higher indoor temperatures than before. This has led to turning off the AC for weeks at a time, opening windows instead, and noticing lower power bills compared with the previous year. Winter experiences were mixed, with some finding the cold harder to tolerate. Overall the group links the medication-driven weight change to reduced need for cooling.

Besides spending less on groceries after beginning tirzepatide, my electricity costs dropped noticeably compared with the same period last year. When I weighed more I would set the AC very low as soon as it warmed up outside and it would stay running all season. Lately the cooling system has stayed off for weeks; I simply open windows at night and do not think about it. After work this evening my partner asked why the house felt like a sauna. I was surprised because the reading was around 74 degrees and it had not registered with me. I know preferences differ, yet I opened windows to reach 70 and pulled out a blanket wrap.

I have not checked any bills yet but I now feel fine at 72 degrees during warm months where I used to want 68. Last winter I would let the house drop to 62. This weekend I got chilly at an event and wished for a hoodie. I like the change and hope it makes outdoor work easier once summer arrives.

LOL yes, the car AC no longer sounds stressed from my size and craving for cold air in summer, and the grocery total is hundreds lower too.

I have always run cold, so it surprised me how warm I felt once I gained weight. Even now at a healthy range I still need a fan at night or I overheat, and menopause is part of it.

I have not seen the bill yet but as spring arrives I notice a difference. Last summer a bedroom at 75 degrees made me miserable. The other night it was 75 when I went to bed and it felt pleasant. I expect summer will be easier. Winter was tougher though; the little time I was home I spent tending the wood stove and inching the chair closer to it.
