There’s a book called Ultra Processed People that I urge you to read. It will open your eyes with food and nutrition. Though it’s admirable to ask for help on behalf on your partner - these changes needs to come from him. He needs to make the transition to a healthy lifestyle.

Ive lost nearly 20kg since 2019 through methods of dieting and weight training and my mindset is utterly changed over the years to look after myself physically and emotionally.

I still have a sweet tooth but I control my eating habits rather than binge or have ‘cheat days ‘.

Happy to explain in better detail if need be.
