There are so many benefits to IF besides weight loss, so I say go for it! My energy levels are much higher which helps me keep up with my busy kids. I can sleep without needing Ambien. My mood is much happier. I will do this for life.
Short answer: Yes. Keep doing IF. Do it for the internal benefits not for weight loss. If you’re already at goal weight of healthy BMI, I doubt 16:8 will ignite more weight loss.
Imo 16:8 is maintenance level for everyone; you can probably stay the same weight, but overall feel better if you stay around 16:8 average 6 days of 7. Imo not insulting 16:8, & it’s a great way to ease into IF. I started that way too. But i think 18:6 or > is where the magic is. That said, for the obese friends in this sub, by all means, start w 16:8. If you need to lose 20% of your body weight it’s going to help with weight loss too.
