Hi Loseit. Please help me! Hi Loseit, 

I have been and psoted here before, but never got anywhere due to being depressed and shit, but I am in a fairly good place and want to change my lifestyle, and weight and most importantly to me, waist size!

I am currently around 300lbs wear 44 inch jeans which are loose ish. I have tried diets but can never stick to them

I want to get to around a size 36 waist, and am willing to take as long as I need. I have a gym membership, so now my questions

What kind of diet is good, and what are some tips to stick to it?

What are good workouts for size loss, due to an long term issue with my tendon, heavy impact (running, jogging) I cannot really do. 

How do I minimize skin sagging, mainly around the stomach?

Any help would be much appreciated!
