To be honest, the cold never goes away, especially if you're doing intermittent fasting. So either like for 16 hours, you don't eat anything, or especially if you do one meal a day, then the cold gets pretty brutal. And I remember even without reta and even with eating a lot more calories than I usually do now, I would still get cold. And I think it's just because I fast daily. I only eat once a day. So everyday is a 24 hour fast. and right now at such a low body fat percentage, theres no barely any fat to provide insulation. so yes youre destined to wear sweaters and jackets in 70 degrees lol
