Lifestyle tips

Ive really wanting the last year at least having a BMI of 30, but I just could get 8kg in the entire year of eating all I've wanted, little exercise, very sedentary. I am currently 170cm and 80kg. I need a weight of 90kg for being legally obese. But I can't! Anyone wants to share their secrets for those extra 10kg?

My wife makes and feeds me cake batter shakes once a week and it has worked wonders. A box of cake powder mixed with heavy cream and a bit of water. It makes 3x20 Oz and our regular Friday date night is her feeding me all 3. At the beginning I could only do 2 but now I easily take all 3. Adds a ton of calories and the stomach expansion is amazing. I'm always hungry now and gleefully eat 4-5000 calories several times a week.
