High Omega 3 keto for those of us 50+

Options
High there, I have been doing Keto for the past 6 years. I have lost almost 200 lbs but I did a lot of water fasting last year and messed up my thyroid. Then keto wasn't working for me anymore. Then I switched it up and focused on very high omega3 keto + vitamin D. Now I am losing again and feel great. Anyone else over 50 doing High Omega3 Keto?
