it does not matter if you eat in a deficit .. it matters WHAT YOU EAT. different foods partition differently in the body. this is something i attempt to educate people about on these forums.
this is the same incorrect mentality from people who eat these 0 carb diets. the people of okinawa are among the healthiest on the planet and lean. yet most of their diet are sweet potatoes which last time i checked have a lot of carbs and a lot of calories. yet they stay lean. the reason? you won't get fat off sweet potato, but you will get fat off ice cream, cake, cookies, etc. even if you consume the same calories. this is why IIFYM is bullshit
having said all that subway is all processed junk. one of the worst thing you can put in your body is a sub from subway. goes right to the gut. they pushed this healthy image for years using a fat pedophile as their spokesman named Jared. people fell for the scam hook, line and sinker. i actually published an article years ago called "the subway scam" you can google it and i was mercifully attacked for it by people. that is how powerful marketing is
