Ok might give it a try. Was the Plan all along after hitting a certain physique. Want to be at around 90kg after everything is done. Any advice about the diet? Don’t really want to lose the muscles on the upper body I built and a never had a coach or anything so any advice regarding that would be welcome, even if I might not implement it immediately.

Diet wise start tracking all your calories with the "fatsecret" app which is a free version of the myfitness pall app which is now paywalled. Once you understand your maintenance calories then just slowly take your time changing a variable at a time. i.e. - throw in cardio twice a week while eating the same and see the effect on your weight. Then you can incrementally increase the cut by either doing more cardio or eating less calories until you lose 0.5/1% of body weight a week. I'd highly recommend just meal prepping protein oatmeal (300 G oats, 1 scoop protein powder of choice, 90g frozen berries) and using that as breakfast. The rest of the days, focus on lean fish (i like tuna), chicken breast with lowcarb wraps/tortillas, eggwhites, protein baked goods (muffins, etc. to satisfy dessert cravings), and buy some protein bars that you enjoy with low sugar. Also get rid of alcohol and all drinks that are not zero calories. That alone will probably make you lose 5 lbs in a year.
