HELP with appetite!!!

Tina • 41 year old sahm of 5

I really need to lose about 60 pounds. I started exercising on Monday and did it every day this week until today. It’s really hard because I have advanced degenerative arthritis in my knees (I’ll have surgery on the right one next Friday). I can deal with working out and I drink tons of water but I always feel like I am starving! I don’t want to take any diet pills and prefer to lose it naturally but eating all the time is having a negative effect on trying to lose weight. My weight is starting to adversely affect my health and putting extra stress on my knees. Any tips to help?!!!
