What happens if you eat 900 calories a day?

Hi , so my goal is to lose 15 kg in 3 months because I planned a trip to London. I’ve been eating around 1500 calories and been losing weight slowly . I lost 20kg in 9months. It’s VERY slow so I want to try eating 900/1100 calories to lose weight more and faster. I’m 115kg , 21 and I’m 5ft10. Is it really harmful if I eat less ? I also burn 400 calories from workout. My daily calorie is 1800 so I’ll be saving 1100 calories everyday with food and exercise.

    I also agree with the above but you won't be starving if you decrease your intake to 1200 a day untill your vacation. You just can't go on a binge during your visit to London. Then when you get back resume as you were.

    Love where you're at and how far you've been already. Don't try to sabotage all of it by too much restriction and making yourself unhealthy now. You've worked too hard to make yourself sick. :( Enjoy London at your new weight, not as a sickly person. If you feel you have to make any changes, maybe 100-200 calories less but truly, you're doing amazing and you *know* it's working. Enjoy London when you go and how about scheduling another trip when you hit goal weight?? Certainly a great goal to strive for along with goal weight. :)

    Alright maybe I’ll eat 100-200 less calories compare to before and workout more. Thank you :)

    I agree with the post above - you've made such amazing progress so far! Don't punish yourself for that by trying to go faster when what you are already doing is working great for you! I can understand the impatience, but a crash diet may put you in danger of putting weight back on once you start to eat normally again, and after you've worked so hard that would be a real shame.

    I think you should keep engaging with forums to keep a positive attitude because you clearly have the willpower to succeed, if you want to 'speed' up then maybe do things like add in lifting weights in small amounts that you weren't before, and make sure your workout calories are well estimated (i.e things like fitbits can be very off).

    But honestly, just well done. Be proud of yourself!


    As they said above:
    'So I am very sorry to say that your priority SHOULD NOT BE YOUR TRIP TO LONDON.'

    Your priority is YOU :) and you deserve to be kind to yourself after such huge success.

    Thank youuuu

    My experience with restriction calories too much is I eventually end up in a binge cycle. Its as if my body turns against me and no amount of will power can keep me from over eating. There has been studies on this too, that its actually a thing where if you deprive your body of calories some people find themselves eating uncontrollably... its like a self preservation thing. Anyway, my point is, you're on a roll, I would hate to see you being one of those people who restrict too much and falling off track because of it. Obviously if youve been able to maintain what you're doing this long, you're doing something right!

    That's not slow AT ALL. With 900 cals your body won't get the energy or nutrition it needs, and it'll likely end up in overeating as it's really really hard to be that hungry for any length of time.tone

    Don't do it, keep doing what you've been doing, slow and steady wins the race. And look how far you've come!

    Wow... the mods have not locked this one yet? Slacking mods...

    Two possible reasons
    1. She's asking a question, not advocating VLCD
    2. No one has reported it so they have not seen it

    Thank you!! 🤨🤧

    Likely to lead to an eating disorder or even worse, depression, if not done in a sustainable manner OP. Like others mentioned, if you choose to continue VLCD for an extended period of time, please consult with your doctor, and schedule follow-up visits.

    With that being said, I actually utilized a similiar VLCD program (1000 calories per day) for 6 weeks with the goal of getting shredded (sub 8%) while maintaining a social life..... markers and checkpoints i put in place:

    1. Bi-weekly physical with thyroid check
    2. 2 social days a week, one planned for maintenance where i enjoyed alcohol/subpar nutritional meals (2200 calories) and another day not tracking anything, complete freedom from caloric goals for the day.
    3. Both days involved physical activity outside normal life (work, etc,) one was a 35 minute cardio session, the other was a full body workout session (roughly 45 minutes).

    Each day, i ate a meal of 2 large chicken breasts with apple whiskey sauce, steamed mixed veggies, and a small package of cashews...only planned meal for the day (OMAD=One Meal A Day) diet. This took place at 8:30am, 6 days a week. Throughout the remainder of each day was mostly flavored sparkling water and coffee.

    This felt strangely comfortable and easy to stick to, knowing i had more than just one day to ease up a bit. I was able to stay on track of roughly 1.2 to 1.4 pounds lost per week.

    However, I would never recommend this to anyone as a solid program, quite risky actually. There are much healthier, sustainable diets to get the results you are looking for.

    I think the most likely scenario is that you manage to eat 900 calories a day for about 3 days. Then break and binge on about 3500 calories, then 'get back on the wagon' for a day and eat 900 calories followed by a 2 day binge of 3500 calories each day before deciding to be 'REALLY motivated this time; and stick to 900 calories for the next 2 days only to decide that its all too hard and give up.

    So aiming for 900 calories a day is likely to result in a "diet" where you're real calorie intake is close to 2300 calories per day that lasts for 2 weeks before you just go back to old habits.

    And that can also happen with 1200 calories for women who are not very very short and sedentary:

    OP - I'm glad you see (now) that this is not a good idea.

    Just to add because I didn't see it mentioned. Even if this were okay for a person's current statistics.....they are not do-it-yourself plans. Doctor prescribed, doctor managed, usually a set of medical conditions.

    Good job on your weight loss so far, you've done a really good job. You're losing at a very reasonable rate. Faster isn't better.
