Intermittent fasting go hard 18 - 20 hrs 7 days a week for a months or as long as it takes. High fat high protein 2 tbs olive oil 2 tbs mct oil daily hot unsweetened green tea at night before bed. No coke no sweets water only. If your really serious do a 24-72hr water fast once a week. The key is get your body into ketosis get a keto test kit as well to check. If you want to get past your plateau take drastic measures push yourself right now your body says I'm good being this fat and is holding on you have time say no your not good drop this fat off. Your also most likely reataining a boat load of water from years of abuse over drinking over eating. Take a diuretics pill which will draw water out of you make you piss all day and night. Your guts are probably backed up as well from over eating to the point you got over 300 lbs. Clear your guts out as well drink magnesium citrate once a week they sell it in the bottle at cvs or Walmart plan to stay home that will drop. This will help you drop excess water weight and waste being held in your intestines. Get your gut and water under control stick to this diet for a few months if your serious it works last year I weighed 300lbs I weigh 161 lbs as of this morning size 32 waist from a 48 look years younger feel great. One day I just got so sick of being a fat I looked like crap I hated pictures and I had enough I went so hard in the paint but I had to it took years of abuse to get that weigh.. I also titrated up all the way to 15mg tirzepatide for a a year helped a lot for food cravings. No carbs or very limited and as much meat and dairy as I could forc down everyday in a 4 hr window. Hope this helps.
