1000 CALORIES A DAY FOR 10 DAYS | Serious weight loss! 

*Note* Although we appreciate your comments. We don't recommend such a drastically low calorie intake. This was a research challenge that we conducted that concluded in it being unrealistic and potentially dangerous over a long term. Please don't attempt this diet, we did it so you don't have to for educational purposes.

I ate 1200 calories for over a year lost 115 lbs, I never felt like I was missing out on anything I recently bumped up my calories since I’m working out more!

I have been doing 1000 kcals a day for almost 4 years now. Most healthy I have ever been, high cholesterol & triglycerides, high blood pressure, and pre-diabetes have disappeared completely as have nagging lower back pain, sleep apnea, and IBS.

Everyone suggesting to lose 1-2 pounds a week is so annoying. I lost 3-5 pounds a week when I lost 90 pounds with no negative health effects whatsoever

I've been doing this for almost 3 weeks and it's surprisingly easy. So far I've lost 16 lbs, and I still have 20 lbs to go. I'll likely be doing this all the way through till September. Update: 25 lbs lost now.

I eat 1000 calories everyday for 8months and I’m 115lbs! Lost 80lbs

I always felt better on a lower calorie diet. Going to get back to that. This past week I started 1500 to 1600 calories a day

If you're getting a ton of good veggies and proteins in 1,000 calories is quite healthy

Im trying to lose 138 pounds to be able to join the Marines. I started at 345 pounds and now Im down to 332 as of yesterday. Im doing intermittent fasting and have only been taking in on average 900 calories a day. I really thought it was going to be a lot harder to sustain the massive calorie deficit but surprisingly Im feeling just fine

Much easier doing 1,000 calories a day if you're doing OMAD.

On day 3 of this, down 4 lbs. Ive got about 70 lbs to lose so this is exciting.

theres a difference between losing fat and losing weight tho right

This is what I did to lose weight. I was 138 and went down to 112 in 2 months. It works, but man was I on edge...

Been doing this the past 4 days. Eating baked skinless chicken, broccoli, squash, plain oatmeal with a little peanut butter. Im 6'4, started at 257, I'm down to 250. I was drinking a gallon of sweet tea everyday and cut that completely out. Going for about 30 days then will bump up to about 1500 calories per day. Hope to drop about 40 pounds in the next couple months.

I work out 1,000 calories 6x weekly and eat 1,400-1,600 cal per day, depending on hunger. I am losing about 1-1.5 lb per week. A lot of people don’t understand the lengths and effort it takes to really meaningfully drop below a set point weight. I am 5’3”, I started at 134lbs now 125 lbs after 6 weeks. If I didn’t work out so intensely I would have to be on intense calorie restriction diet like this, no more than 1,000-1,200 calories. Some people are just metabolically slow and require a greater calorie deficit to lose weight than others!

I've been doing 1000 cal for a day followed with intermittent fasting for 11 days now, my waist shrink from 33 inch to 32 inch, i lose about 3kg while eating anything i want and no exercise... I know I should but I'm just have no feeling to do consistently😌

If you eat mostly vegetables you will find it hard to eat more then 1000. After you get used to eating at low calories the hard part may be how to increase your calories in order to retain weight

I eat between 1000 and 1200 calories (yes for weight loss), but I never feel tired or sick or anything, I feel full and satisfied and waaaay beter than when ate more :) EDIT: Wow I didn't expect this much response to my comment lol, notifications are turned off and didn't bother checking again. Update on my weight loss, I don't eat 1000kcal a day anymore more around 1300kcal now. I still track but sometimes I just don't reach 1300 as I'm not in the mood to eat much on some days. As of today 1 Oct (started: 6 Feb) I lost 47lbs, +/- 21kg. Currently weighing at around 127lbs, 57kg. Of course with ups and downs, plateaus, etc. Really happy with my weight loss but still want to lose a bit around 2 to 3 kg. You all can do it!

I consumed 870 calories today and felt good. Doing it for 10 straight days is a completely different battle haha. You don't need to eat as much food as you think. I also ran 4.7 miles on the elliptical today ! Crushing fat and Rising Above Sugar !

I’ve eaten 1000 calories per day for 4 weeks + running 55-60 km/35-38 miles and strength training twice a week. Have lost 9.1 kilos/20 lbs so far. Hungry sometimes, but I actually feel quite good!

A 1,000 cal per day diet with exercise will give me 1.7 pounds per week weightloss. It pushes me into an "avalanche" region where weightloss rate is the highest possible. However, I could never do it while employed (I'm retired now). I've only done it when unemployed and retired when I can sleep and rest during the day when fatigued.

I did this for 2 months and lost 40 lbs in 2 months.

Agree, this isn’t sustainable, but a good experiment none the less. I think it would be useful for anyone with a holiday coming up or an event, in which they want to lose weight quickly. I think I’ll give it a go myself.

The real trick is to eat until you’re 2/3rds full.

wow thats actually alot i will try it out.

I've been eating once a day 1000 calories for 30 days so far full of energy and looking to keep it going for 1 full year

damn been doing this for a week and im feeling fucking amazing

Go to county jail. You get your 1000 calories and lose weight just fine

I need 1200 cal a day to lose weight. 30kgs to go. Hopefully before I die

I eat 1000 calories per day and workout all day. I stopped running for a week to rest because of my injuries but I went from 145 to 139 in a month and a half. I will continue to eat 1000 calories a day for probably like a year or until I get down to 125 (I’m 5’6) but I honestly feel so much better then when I was in school and completly stressed and ate too many calories

Was just wondering if you kept some of the weights off once you went back to a normal caloric intake. Were there any negative affects post experiment?

I eat 1,300 calories a day and have lost 16 pounds in a month. I’m 5’4 and went from 145lbs to 129lbs

Am I the only one that thinks that my man looks like Jeff Nippard in the thumbnail?

When you do it you really realize how much you eat

I'm on a 200kcal deficit (should eat 1500, am eating 1300) for a month, it's been good to me, I think I lost around 8 pounds (not much😅), going slow but steady. After a few months on a deficit I'll readapt to my new amount of necessary cals to maintain and consume that for a while so my body can rest and adjust to the weight loss I'll have had so far. I read about how maintaining helps on the long run so thats my plan. Dont restrict too much if you truly wanna keep the weight off! also focus on protein levels, proper hydration and weight lifting (more important than cardio). :)

First time I gained serious belly fat was when I started working in offices. Calorie counting has taught me what a fool I have been to not count. I feel like I never wanna go over 1500 since the past 2 weeks have changed my life and my fuckin abs are popping out everywhere. Im 36 this is the first time ive had a consistent waistline and no belly fat. This is amazing i feel like im getting back my childhood. I eat what I want and it seems to never make me fatter. Simply amazing. I pack sandwich baggies full of cereals chips snacks and digitally scale them to 300, then eat 5 bags at night in an intermittent fast. Sometimes i eat other things subway veggie subs, calzones with spinach but i still do the math and use baggies. It works! Eat what you like and stay slim

I started intermittent fasting recently. I went low on calories in the beginning. After about 4 days, I got tired and hungry. I had to up the calories to feel better.

I've been eating around 1000-1100 calories a day for a week now, and I went from 51.2 kg to 49.6 kg. I use an app called MyFitnessPal to track my calories, and also to estimate when I'll reach my goal weight if I consistently eat within the limits. So far, I've been sustaining it and it feels renewing for me honestly. I don't know if it's for everyone, because I have only been doing this for a week. My hunger levels are lower, and I don't get cravings as much. I also noticed how I've been eating until satiety, which has been very difficult for me in the past. I think between 1000-1200 calories is enough for me, because I am 5'2, and only walk for exercise. I'm going to continue doing this for a month, to be down to 47-48 kg. Super curious, and maybe I'll do an update if I'm successful!

I’ve been doing this for awhile I always eat 1000-1500 and I always feel fine no changes I feel healthy energetic and great however if u feel sick or bad u should eat 2000

I started a week ago that challenge and to be honest i have never felt hungry since the beginning and its easier than i expected (I am 107 kg so im used to eat a lot more but because i eat mostly fruit and vegetables the volume of food is satisfying)

If you are trying to lose weight and doing a severe deficit, your body will react better to eating 1000 calories as one meal and fasting for 23 hours. Cool video

Curious how this would go if you basically used lean protein to hit like 140 grams per day. Casein, chicken breast, lean steak etc..

Agoge Diet personalized plan makes it simple. Select the food you like and they give you personalized meal plan with tips, workout plan and healthy recipes.

What was the first thing you said it was?

If you do feel like doing a challenge again.... Try 1000 cals but only have water and coffee in the day and eat your 1000 cals in one meal at night. You'll feel so much better than when you spread the cals throughout the day. Well done.

great incentive! haha love the music at "Part 2"

Hey, I’m skinny fat, 28 now so my fast metabolism must be slowing down. Working from home so barely get out or active. Got a gut on me that I’ve never had before and my face is filling out more. Would it be dangerous for me to simply eat a lot less? If my sole aim is to lose fat off my face and body? I’m not sure if this would be dangerous or not as I’m a complete amateur when it comes to this stuff

Hey if I wake up at 2:00 PM each day would it still be unhealthy?

Here’s my story with this diet: (20 year old male 5’10 and 192lbs) I ate 1000-1200calories a day (mainly 1000) for 7 weeks straight. Total weight loss was 28lbs (id say 4-5lbs of water weight). The key to this is to EAT WHAT YOU WANT! I ate pizzas, kebabs, loads of carb loaded breads etc and it did not matter as long as I met the 1000cal goal for the day. Drink diluted juices instead of water all the time so you don’t get sick of the diet. The question everyone wants to know the answer to; do you gain all the weight back once you up your calories? Simple answer... nope. I did in fairness gain the weight back due to demanding job and studies but it took me 6 months of binging on 3-4K calories a day (mainly takeaways sadly). So basically you’d have to really overeat constantly to gain the weight and at the rate I was going, I would have gained weight either way. Started the diet back up again and easy as that, lost all the weight again. Don’t currently have a job due to the quarantine so I won’t be putting it back on anytime soon :)

Dude I only eat 1K calories a day and everyone is saying it’s not healthy oh my gosh. I’m trying my hardest to increase it but I can’t I’m full all the time. 18yo

just looking at this now - but did you net workout against food consumed - like if you burned 500 calories running could you eat 1500?

So guys I’m trying to get a six pack I’ve been working out all year but I haven’t gotten any results a month ago someone told me I need to lessen what I’m eating and try for 1000 calories a day I’m 15 I weigh 165 pounds and I’m 5’11 how long do y’all think it would take for me to get my goal of just visible abs or six pack

I’m on day two of under 1,000 calories AND I’m quitting added sugars for good. I’m super tired. I cried way too easily today too 😅 I think I’ll be fine tomorrow but it’s weird how tired I am. I got 8 hours of sleep, did only 5 min of hiit (it was intense) and took a NAP. I shouldn’t be tired :/

Pair this with a crazy 6 day a week workout routine and you’ll lose fat fast as hell

I'm around 200 pounds and started taking 1000 calories diet and also buring around 500-800 calories a day..Does any one know is it bad for health?

hi! i wonder how many of each food did you put in each plate? grams or cups?

It’s not the latest scientific evidence. The evidence says it’s healthy. It’s old fashioned to think 1000 calories is dangerous.

Been doing it for a month now sadly don’t own a weight scale so can’t confirm how much I’ve lost but also doing 100 push ups and crunches everyday as well. Perfectly healthy but yes I agree my caffeine intake has increased because after a while it does make you feel like shit

On a 1200-1300kcal diet this is what I eat: Breakfast; 2 pears & 100g strawberries. 1 Muller light yogurt pot. Seems to fill me up or 2 poached eggs on toast Lunch: 200g cucumber, 50g humus, 120g smoked salmon, slice of seeded bread and 40g dry roasted nuts (morrisons are the best) Dinner: Really varies but normally a medium/large sweet potato with a can of tuna and a few tablespoons of light mayo with baked beans or something Snacks: Seafood sticks (only 20kcals!!) Flavoured rice cakes Plums and apples Toast Bananas Roasted kale. It does vary but that's what I eat. I do not drink enough either so yeah...

And how it's going with muscle grow with this smal.of caloris. Are you able to grow with this in mucle building?

I see people on here saying that they eat this low and lose weight and then the replies are always asking how to do that, etc. I’m just here to say that that is not the way to do it. keep in mind height, weight, age and gender vary the amount of calories you need but no one should be eating 1000 or even 1200 calories to lose weight, that’s WAY too low. For context I began my weight loss journey on June 11, 2019 where my starting weight was 234.6 lbs at 5’8. I am currently 19 years old and weighed in at 168.2 lbs this morning and I eat 2,300 calories a day (and I’m still trying to lose more weight). I would say I can maintain my weight with 2,700-2,900 calories. I don’t have a “fast” metabolism or great genetics, I just focus on lifting weights daily and building muscle while eating at least 1 gram of protein per pound of body weight. I also try to get in at least 10,000 steps every day and I love to play sports such as basketball or football. Even during the quarantine I am continuing to lose fat and build muscle while eating that much. Once I reach a point where I feel a bit more comfortable I will slowly increase my calories by 100 calories a day every week until my weight levels out and I will try to maintain that for the foreseeable future. I am writing all this to say that if when I first started my weight loss journey I had seen some of these people claiming to only eat 1200 calories a day I would have never even tried to get healthy. I am just telling everyone who loves food like myself that you can lose weight with a lot of food if you take your time and work on building muscle while losing the fat.

I’ve been intermittent fasting and eating 1000 calories for 1 month and lost 21 pounds quick I’ve felt great so I say it depends on who u are Bc it might work for me Buh not for others so I say just try it and if u feel sick then don’t try it

are you from liverpool? sounds like it - at least nearby - i miss it there. thank you for uploading this, though. interesting thing to see conducted!

I like your video, I do agree that it is not a problem if you consult a doctor for weight loss. 1200 calories a day for an obese person is often recommend with the exception that it is monitored. I do 1200 calories a day but it is well planned with nutritional meals healthy carbs, low saturated fats and portioned control proteins. Most of my meals have lots of low carb veggies.

I am on 900 calorie 30 day challenge ,and today is my 10th day plus workout 6 days a week cardio plus body weight etc I am already at 154lb with already 4lbs below my absolutely perfect weight.

I’m eating 1000-1200 calories a day and I’m on my third week. At the end of the week I’ll go eat anything I want as long as I’m at a calorie maintenance. I haven’t been hungry or craved if anything my hunger has been going down and I’ve lost 4-5 pounds already. I love it. Obviously this isn’t going to be forever. Just until i go to where I want to be then I’ll be at a calorie maintenance all the time

I’ve always been knows for having a massive appetite since I was young. Always eating loads and loads and never putting on weight, probably like most teens. I’m 21 now and recently realised I was putting on a lot of fat around the waist and stomach. I’ve decided to cut down to 1300cals a day from my previous 2500-3000. I’ve lasted 2 weeks so far and realised the last couple of days I’m not even missing eating huge amounts or getting fast food every other day. I feel healthy and good. I will probably go up to 1500-1700cals as I know 1300 probably isn’t sustainable long term and I will end up on the other end of the spectrum. But so far so good

Wait .. what are his results again ???

I’ve been doin this for 5 months- I’ve lost 54 pounds

Jeez people get so sensitive about low calorie intake these days. There are people who fast for days straight I’m sure eating a bit less for 10 days is fine.

I'm doing a 1100 cal diet a day (log and weigh everything meticulously) as a 5'8 290lb male , eat 40% protein, exercise every day and my weight and waist circumference are not going down. Normally I should be losing weight very quickly as I'm in like a 1700 calorie deficit every single day. Do I have a medical condition?

this really does work and I recommend to do this or just eat low portions. worth it completely

Today is my first day on 1k cal/ day. Wish me luck. I skipped breakfast I ate 4 eggs fry in bacon fat. I had 2 slides of bacon 1 cup of spinach. 2 chicken thighs 2 cup broccoli 1 medium apple and 2 tsp of peanut butter.

That's WAY MORE THAN 1000 CALORIES!!!! That's at least 2500 healthy calories!!!

I’ve been doing this for a few days I’ve been consuming about 1000 calories a day and I’ve been exercising every day burning about 900 calories a day plus you burn a lot by sitting and sleeping, will I lose weight because I can’t tell because I don’t have a scale and if so will it be effective

I went from 100kg to 73kg in about a year from eating just 1000 calories a day. Aswell as riding 30kms every second day and lifting weights every other day.. it is really hard for me to lose weight .

After the diet, when you started to eat normal again, did you gain weight back?

It would of been alot more bearable if ya did it with intermittent fasting you just eating 4 hours after you wake up youd loose more weight too

Trying to stay around the 1000 calorie mark because my BMR is usually around 1000-1200. I’m 4’11” and around 43kg. Sometimes I work out sometimes I don’t. I mostly do cardio because I am too scared to try strength/core training. I do a steady jog pace on the treadmill for an hour with 3 breaks in between. And then I use the elliptical for about 30 mins. When I am exercising I burn about an average of 450 calories. I work out about 3 to 4 days in a week. On my lazy days though, I am REALLY bad and I stay at home like a couch potato. I feel like I’m ruining my metabolism. 😢 Suggestions are very much welcome.

18 packs of space raiders a day = 1044 calories. I started with 3 meals - 4 packs for breakfast, 5 for lunch, 9 for dinner (2 of these as a desert). But now I found little/often works better. Doing very beefy guffs. Not lost weight yet.

I've been eating 1000 calories a day for 7 weeks. I lost 50 days.

Uhhh okay but am I the only one that has been eating this much basically my whole entire life...?

I’ve been trying to eat low cal, I feel great. The only hard thing for me is eating enough calories with healthy food, as my goal is to eat 1,000-1,200 calories a day but healthy food is so filling the most I could eat is 800- 950 calories a day. **so far lost 10 lb trying to do a low cal diet**

How do you guys deal with the nights? For me I find it difficult To sleep

I eat 1200 calories per day sometimes less. It is a bit hard for me since my stomach can't handle so many calories but I eat 3 meals per day including dessert. I do not work out and so far I have lost 3 pounds in 3 days.

I use a calorie app and slightly modify exercise and watch blood sugar levels, and rarely drop below 1800 calories per day. Your plan is interesting, but if sugar drops below 80 and you get behind the wheel of a car, that could be a liability if anything happened.

I did intermediate fasting 16:8 for one month and ate 1000 calories a day and last only 2kg any anyone tell me why

@7.40 you said you were 13st 11lb and @13.54 you say you were 12st to start with. Did you lose 11lb or 1st 11lb?

I have been doing this for around 3 months now at most, I have lost 42 lbs and feel a whole lot better with myself. Before this diet I was most likely eating around about 3,500 calories or more a day, starting at a weight of 110 KG and working my way down to 85 KG so far, I'm planning to lose a little more weight and then start eating the calories I personally need to maintain the same weight. In my experience this hasn't effected anything other than my weight. My muscle growth is the same to as it was when I was on the bigger side, my mood is the same or better than it was before this and I finally fit into all my clothes. I recommend only eating 1,000 - 1,300 calories if you're around 5 feet to 5 feet 8 inches (I am personally 5 feet 8 inches tall) ...If you're on the taller side you may want to eat 1,500 - 1,800 for this to work for you, if you do not want it to be dangerous for you. This diet may not help you if you're eating 1,000 or whatever calories of just junk food though, I normally eat food that is mostly good for me with the odd bit of junk food here and there, I recommend eating stuff like white meats, fish, potato, home-made fajita's, rice, low-fat pasta, yogurts and low calorie breakfast foods such as two slices of toast or Bran Flakes/ Museli (Museli and bran flakes are my personal favourite for breakfast) Ask me any questions in the comments if you're worried or curious about this diet.

Good test. I think that you have to keep going with the diet. You would probably stop feeling hungry during the third week of the diet. I'm consuming only 949 calories a day and I'm in my third week. I feel less hungry now. However, I spent three to four weeks overeating before doing this diet, thus I may be less moody due to the extra food that I allowed myself. Congratulations on losing some inches off your waist and some weight!

where is part 2?

I’m really confused, everywhere says that 1,000 calories is drastically low. But my maintenance calories are 1,400. So if I cut down to 1,000 to lose weight it isn’t such a big difference. Does it not depend on the person?

Why don't you make a chilli con carne with the mince lol. Wouldn't it be more interesting

Been doing this for a month 10 pounds loss

I’m thinking with all the comments that the amount of calories you need to eat really depends on activity level. If you spend most of the day playing video games or at a desk you’ll probably be okay with 1000 calories. If you’re a busy person running around all day , working out and you play sports then ofc 1000 isn’t enough. If you feel good that’s what matters.

(F 6'1 start of 10 days 200lbs) *I started this 1st Jan- I'll update* -01/01 -Easy. I ate that much over Christmas that it felt refreshing. -02/01 Haven't had much of an appetite today so it felt easy -03/01 I felt satisfied with what I ate -04/01 I had cravings for junk food so I ate some small chocolate bars within my calories. But that meant I didn't eat much quantity

Dose it madder on what you eat?

Would you need to exercise as well to lose weight with this?

So does he eat just 1 of those containers a day?

I am very inactive as an uber driver. I figured why not started eating 1k calorie's a day since this is about the only way I could actually lose weight by still being inactive. (This is by the way extremely easy for me, probably because Im so inactive physically). Have been losing about 1 pound a day for the last 10 days, and don't plan on stopping for another 10. I don't feel like im deficient in anything. I eat plenty of greens, and fish. And honestly don't feel that hungry at all. I eat twice a day, doesn't matter what or how many calories for each, as long as it adds up to 1k. EVERYBODYS BODY is different. I can easily get away by only eating 1k, but this is because Im so inactive. Try what feels just under ur comfort level with the ammount of calories you eat. I suggest you eat half of what you would normally eat per meal, then wait at least 2 hrs before eating again. I found that by doing this, my desire to eat in general went waaaaaay down. If in 2 hrs you feel like eating again, eat. But you probably won't want to.
