The simplest but not the easiest way is to track yr food intake. Jog for 5km burns are 300kcal while avoiding 1-2 bar of KitKat does the same effect. It's not hard to decide which route to go to.

Crash n burn with this kind of diet. 50g of carbs makes u feel like crap, 20g of fat makes u less of a man.

What makes u think I have not? I tried, hence the reply. How abt u? What gives u the right to jump on ppl blindly? That fella is talking abt low carb n low fat u douchebag. U on the other hand is on low carb, hence definitely on high fat. So where is the similarity here? Unless u r saying u r hitting pr's on low carb n low fat, then I'm interested. If not, f off.

I would start on some jogging or some low intensity cardio to build up stamina n get yr body used to moving. Then add on HIIT later on.

Insulin sensitivity depends on body fat level. The higher the bf, the lower the sensitivity.

IF is a way of eating. Nothing significant though ppl claim more focused, high growth hormone etc but studies have been inconclusive. The only thing that is conclusive are u burn more calories than u consume, weight /fat loss will occur over time.

And the best diet is the one u can be consistent with.

2 weeks ain't long enough to have any conclusions whether what u do is on the right path. Give it abt 6 months.

Fuuuuhhh 900 kcal... All the best dude
