@dancibutterfly youre not allowing your body to enter ketogenesis. also, no i dont mean keto as in the keto diet i mean ketogensis the metabolic pathway. ketogenesis the metabolic pathway is activated when there is 0 food entering your body. Yes, it can also be triggered via consuming an extremely high fatty diet but Fasting also triggers ketogenesis, faster and more efficient anyways.
You're not losing weight now because your metabolism is lower than 1000 calories. you can either increase your physical activity which increases your metabolism past 1000 calories. Or you can fast to allow your body to enter fatty oxidation of your excess fat storage. you can also fast and increase your physical activity.
I lost 90 lbs in 1 year via cardio and fasting. My routine was fasting for 18 hours a day, small oatmeal before gym, go to gym and perform 90 minutes of zone 2 cardio, return home and have a single meal.
my routine made use of ketosis, allowing my body burn away the glycogen in my blood while i fasted 18 hours. eating before gym gave me a bit of energy to exercise from my energy depleted state. immediately after my meal i would ride by bike 30 minutes to the gym, 90 minutes of zone 2 cardio, then 30 minutes cycling back. the meal i had before the gym was burned away from 150 minutes of cardio AND my insulin instead of spiking and crashing, it would slowly burn away meaning i wouldnt be feeling peckish because of a resulting insulin crash.
have you ever eaten a huge meal gotten full, yet you catch a glimpse of desert and suddenly you dont feel full anymore? yea, that is not just a feeling it is physiologically detectable. Your body anticipates a new SWEET tasty meal by sight alone and your body releases a surge of insulin and other hormones in anticipation of this new food. so my meal was both burned away from my cardio, and my insulin was returned to normal, meaning i wasnt insulin craving foods.
the 150 minutes of cardio both burned the meal i ate AND zone 2 cardio is slow enough where the body selectively chooses to conserve your precious glycogen and instead oxidize your fatty storage. if you just start sprinting for cardio, your body will burn through cardio and completely block the oxidation of your fatty storage.
tldr:
your basal metabolic rate is higher than your calorie intake. continue eating the same amount while increasing your physical activity to increase your basal metabolism.
