Need help with average weight loss per week

Talk to a nutritionist.

If your only consuming 600 calories a day, and you've stopped losing, your body is in starvation mode. When our calories go too low the body responds by hoarding what it has. I've been there.

Good weight loss happens when you hit about 1,200 calories a day. Less than a 1,000 routinely will slow things down.

I'm not a dietician or nutrionist but have experienced this for myself.

Hope this helps.

Anything under 800 calories and your metabolism shuts down to conserve energy (there's some debate about starvation mode, but I'm a believer). I ate about 1200 all along and lost 1.31/week through most of my journey post-op and that gradually slowed...about 20 pounds from goal it was .75/week. Keep in mind that I started at a lower BMI (about 38) than some. Up those calories with more lean protein.
