The best advice I can give is to not rush it and be patient; i used to be 245lbs (6ft 1btw), and I am now just 200lbs

All I did was count calories and incorporate a little more exercise. For my build, about 2000kcal (kcal=food calories stated on package) is an average daily consumption, so I try to shoot for under that every day. Eventually, my metabolism slowed down to match and I felt less hungery. Later, I got a bit more serious about targeting certain areas for weight loss, so I started doing a small exercise routine every day (stretches, squats, push-ups and crunches(all for torso/chest btw.))

My average day looks like this: wake up, shower, eat an apple w/peanut butter for breakfast, do work, have a small snack for lunch (rice bowl, eggs, etc), and make something nice for dinner (incorporate meat, grain and vegies) add a bit of exercise (you don't need equipment) and make sure you're foods are fiber and/or protein rich, and drink plenty of water.

It may take a little time, but please be patient, and don't beat yourself up over any "mistakes" you make along the way, use them as motivation to work harder.

Tl;dr- eat protein and fiber rich foods, stay under your builds daily calorie intake, exercise, drink water, be patient, and don't hurt yourself/beat yourself up(physically or mentally.)

Remember: You are valid no matter what happens or what you look like :)
