My aim is to drop 25 kgs in 16-24 months. All i need to do is start kicking my butt to man up and get back to the workout routine
Don't get any injections or medicine. The 'miracle' weight-loss pills will fuck your hormones (like Ozempic).
Just eat high volume low calory food and it's easy. I'm myself at the moment doing a longer cutting phase.
3 months cut at 500 calory deficiency, dropped to 15% bf --> then 2 week maintenance to reset metabolism and hormone levels --> 1 month cutting phase at 400 calory deficiency to drop to 12% bf.
Keep your cutting phases' weight loss at a maximum of 0.6% body weight/week. Keep your cuts at 3 months max. If you want to do back-to-back cut phases, do at least 1 month maintenance in-between.
E.g.
3 month cut --> 1 month maintenance --> 3 month cut --> 1 month maintenance.
Workout 4x a week with high intensity during the cuts.
2-2.5 grams of protein per kg of bodyweight during cuts. Fats at a strict minimum of 60g daily. If you don't get enough fats daily, your hormone levels will get fucked.
Also, prolonged cuts will lower your testosterone, and if not done correctly, your testosterone levels will never return back to normal.
So,
no miracle drugs,
keep fats at a min. of 60g,
very high protein intake,
no prolonged cuts,
maintenance phases between cuts to reset hormone and metabolism levels.
Once you get to like 15% bodyfat, you should just go into a very long maintenance phase (6-12 months) to hard reset hormones, and do a body recomp (lose fat and gain muscle at the same time, Google it) at the same time.
Get yourself a Ninja Creami and a shitton of good tasting protein powders. Helps with not relapsing as you can eat a pint of ice cream every single day. Just do milk and protein powder + xantham gum.
Then start eating cucumber salads. 300-400 grams of cucumber, some red onions raw, protein, sriracha, whatever. You can eat like 1kg of food for like 500-600 cals - keeps you really full during cuts.
If you can spare like 4-500€/month, I can refer you to an amazing personal coach who'll get you shredded in two years.
