You stated you're not hypothyroidic so you don't have any medical conditions. Having said that, your basal metabolic rate would be right around that 1500-1700 cals assuming you laid in bed all day. Seeing as you're active and do shit you would lose weight at that calorie intake. Unfortunately it's very common for the obese to either over report their activity or under report their food intake or even both.
You don't go from maintaining your weight at 1500-1700cals a day to barely growing at 3000cAls a day just bc of gear. And if you truly believe that then I regret to inform you but you're the idiot here
Anyway, we can all sit around The campfire and tell each other stories but that accounts for shit in terms of evidence. You could've made progress in spite of what not bc of what you did.
The reason you blow up on carbs is bc you restore muscle glycogen levels which also holds water. You don't get fat all of a sudden.
So bc you asked me so politely and sweetly, what you said is about 95% bullshit. The other 5% was a campfire story to share with your bros....idiot
