Don't seek dietary advice on the internet. Obesity is not an easily handled condition. Assemble a team to help. The lead should be your primary doctor, of course. But call in every specialist your particular case needs. Nutritionists, Dieticians, Physical Therapists, Fitness professionals, religious support, mental health professionals, whoever is needed. Maximum effort and focus! Treat this as if it is a life or death issue. Because it could be just that.
Praying for you. Be well!
