Which TDEE is right?!

I've typed in my details to 5 different sites and they're all coming up with different numbers! Which one should I use? :bugeyes:

He he I had the same problem.
Only you can determine your TDEE mainly by experiment and experience. Based on my experience, the most accurate TDEE for me came from this website:
But it is quite lower than other websites' results and I'm thinking that it is -close to- accurate because I have hypothyroidism.

I know! It's very confusing. I'd go for the middle one and see how you get on. If it doesn't feel like normal eating, or you don't lose weight, you can adjust!

If you're managing your intake on feed days then the TDEE maintenance number is the one to start with. The deficit for weight loss comes from the fasting days.

Technically your TDEE is the amount of energy that you usually expend per day, there is only one number. The others are deficits to the TDEE in order to lose weight.
