Up to date pic of me (2 goals for physical health)

Here's me at 284 pounds today. I'd like to get back to my goal weight of 235 by the end of the year.
There's 20 weeks left in 2020 today and I need to lose about 50 pounds so that is about 2.5 pounds per week.
My energy is better at that weight and there is a big relief to my knees and back as well so I am motivated.
How am I going to do this?
Namely diet and exercise.
Eating healthier and making sure I have enough physical activity to stay in good shape.
Just use common sense and keep in mind that I am about overall mental, physical and spiritual well-being.
Anyway those are a couple physical goals.
