Love that pic! Yeah- always remember calories in, calories out. Also, I am 6’ 3” and 238 pounds so a i would drop 5-8 pounds of water the first week of keto (while heavier at 255-260)and then it was a slow drop for weeks until it started to snowball after 2-3 weeks in terms of weight loss. Find out your BMR (typically body weight x 12 so your BMR or calories burned at rest is roughly 2000 calories. There are many calculators for macros although I never used them. With keto, you can easily double that so proceed with caution.
I am dealing with COVID and recovering so still eating good meats but added carbs and “regular food” to boost my immune system. After this is over, I will be doing more of carnivore type lifestyle, only eating meat and supplementing with vitamins and minerals. Have done carnivore and keto and for me, carnivore worked best because I literally ate once or twice a day, usually 1 or 2 ribeye steaks- that’s it. Just found it more convenient as getting quality high fat can be a challenge while traveling.
best of luck!
