11 pounds in one week 😆

I've been on the OMAD diet for one week now and I weighed myself to find out that i went from 155kg to 150.2 losing approximately 11 pounds, the best thing about diet is that it's not just only a way to lose weight but the act of not eating has made me more disciplined, I study for longer ours ( my stomach isn't full of food so actual blood is going to my brain 😆😆) , i hope i can keep this going

Always quit :(

I am a quitter. In 2020 I tried fasting for the very first time in my life and went from 220lbs to 170lbs from January 2020 til September 2020 (started with 16 hrs and went to 20 hours plus exercising). Since then I gained everything and more back and quit every time I attempted to restart IF. I tell myself I will try again and again and always quit. However, even though I quit fasting I don’t quit thinking about going back to fasting.

I am giving myself next 7 days (Sunday to Sunday) to try 18 hours fast! I am 235 lbs now. My heaviest weight ever! Did anyone try for years like myself before actually going through with it?

is this intermittent fasting?

if I ate just regular meals every other day and fasted every other day, would that be considered intermittent fasting, and would it have any benefits (ie weight loss etc.)?

(I don't really understand intermittent fasting very well ... but I thought I would ask this question to get started.)

Walking or strength training with omad?

I've very recently incorporated some workout in my fitness regime along with omad and IF on and off. My question is what would show better results in a short span of time (say 6 weeks) walking with omad (close to 8k steps a day) or some strength training with omad (light to moderate exercises). I know reaching my goal weight will take a lot longer than just 6 weeks but I have an event coming up and I want to look visually slimmer. Please help.

is intermittent fasting necessary for me?

CW: 140lbs |GW:125lbs

I’m wondering if intermittent fasting is actually necessary for me. I’ve been 120 pounds my whole life and have gained 10lbs of muscle and 10lbs of fat in 2 months. I just need to lose 10lbs of fat.

I’m not sure if this diet will just make me gain weight in the long run, by raising my cortisol levels?

My diet isn’t the best, should I increase my fast length?

CW: 185 GW: 140 Height: 5 foot 8 28F

I don’t have loads of time to cook food and food shop as I’m a medical student… does anyone have any tips for quick, tasty, easy healthy meals? Also… if I eat things like pizza and oven food instead of healthy things, should I do 20:4 instead?

Proud of myself today

Have been pretty much exclusively doing OMAD fasts for about a month now and lost about 15 pounds. Social settings always screw me up and I had my first today, where I attended a Mother’s Day brunch and a baseball game. Normally I’d say screw it and let myself indulge but I didn’t want to. Instead I kept to plan (imo because I I’m just estimating in terms of calories here) and didn’t overeat.

Brunch was -water and unsweetened iced tea with lemon -3 raw oysters -half of a crab cake benedict and a side of fruit

At the baseball game -water -hot dog with light ketchup/mustard/relish -about 2-3 cups of popcorn (wasn’t overly salty or buttery) -a couple french fries

Finished at 5:30 and will now continue my 24 hour fasting 😁

My last meal yesterday: breakfast - oats, cows milk, peanut butter and honey.

I did drink the following during the day yesterday 1 x Coffee (decaf) with mtc oil 1 x Rooibos /redbush tea with mtc oil.

I'm on the following medication. Took meds yesterday before breakfast and today at around 7am 72g concerta 300mg zyban (bupropion) 20mg Escitalopram

Not losing inches or weight but still look smaller to myself in the face and a little in the stomach

Question followed by back story-

I didn’t lose any inches, but felt like I looked slimmer and my clothes fit a tiny bit different. Boyfriend said I felt smaller but nobody else noticed anything. I’m almost positive boyfriend was just being nice, and it was all in my head when the reality probably was I actually didn’t look any different at all otherwise I would’ve lost inches right?? Thoughts, experiences?????

Context: Female, 29, now 243 lbs. 2 kids. No exercise. IF 24 hour fasts Monday, Wednesday, an a Thursday. Low carb/lazy keto. One meal when I do eat, and one snack. Half of my body weight in oz in water daily.

I lost 70 lbs over the course of 6-12 months. unfortunately though, that was 3-4 years ago and I ended up gaining all the weight back. Fast forward to today, I’m doing the same exact thing, had 3 perfect months, went from 253 to 235 and I started to feel like I was looking slimmer in the face, and as weird as it sounds my apron belly was almost changing shape? I didn’t remember that happening last time. Boyfriend said I felt smaller, but literally nobody else who didn’t see me everyday noticed any change (when last time they would never stop about how good I looked). The thing is, I didn’t lose a single inch! Fast forward to about 3 weeks after this I got extremely discouraged and decided that since I didn’t lose any inches and I’ve slowly gone back to my old ways because NO inches lost, I plateaued in weight, and not a single person noticed any difference so I came to the conclusion that it was all in my head, and I didn’t look any different because if I did at the very least I would hve lost inches. Well I’m going to pick back up before I spiral out of control again.

I appreciate any opinions, advice, or personal experiences shared.

Seeking advice for losing weight

I am looking for advice to lose weight, i have basically no experience with IF, I got some questions and I am looking for advice.

I am 19 years old, 280 pounds, 6 feet tall, 36% body fat, Goal weight around 240. I have always struggled with my weight and I am at a point where I need to change it. Right now my plan that I cam up with from little research is going to be a 16-8, to get me started and then transfer to 18-6 withing a few weeks. I work in healthcare, about 40 hours a week, 25 or which is typically walking around or physical labor(im a home care aid, so i do basicslly anything you do throught your day for people). I plan on doing about an hour of physical excercise a day on top of work, whether that be a walk or a peleton bike, my eating times will likely be 2-10, or 3-11. I have a really bad habit of eating at nights when im bored. I got a few questions,

  1. Can i drink coffee outside of the times with milk?
  2. Any tips for helping with the urge to eat when bored?
  3. What else can I do to help myself?
  4. What supplements should I be taking?
  5. Can i have 0 calorie foods, like powerade zero outside of times?

I will prolly have more questions, so there may be edits or comments. I know i could have found all this out online, but i cant get the advice that I dont know to look for.

Fast like a Girl

I'm on week 5 of IF and I've been really affected by my menstrual cycle. I've always felt bloated during my period, but after starting IF I've noticed changes in my energy, cravings, ability to exercise, and also bloating (not just during my period but all throughout my cycle. I've heard about the book Fast like a Girl. Has anyone ever read it? Do you feel as if you got good advice from that read?

When they say drink your water …

Do it!! I wasn’t and got dehydrated enough to send my heart into an arrhythmia. I guarantee the cost of that ambulance ride and 6 hours in the ER is a lot more expensive than a jug of water. (I’m ok now just have to take some meds including a blood thinner.).
The cardiologist told me that IF was fine to do just drink the water. Lesson learned the hard way.

First Month of IF Complete!

Hi everyone! I’ve been out of the health and fitness world for a decade now. After just steadily gaining and gaining over the last 6 years I’ve decided it’s time to stop with the self hatred. I’m tired of looking and feeling like crap. When I first lost weight I went from 172 to 112 age 15-16 and 5’4, mainly with IF/OMAD.

It has now been a decade and I’m getting into the swing of things again. Today marks the end of my 4th week doing IF. Started with 18:6 for the first week and a half, followed by OMAD, and the past week has been about 16:8 and 18:6. I have also been trying to walk between 10-15k steps a day ( though I don’t quite hit 15k as much as I’d like to) and now trying to incorporate a little strength training.

4/14: 229.2 lbs 5/11: 212.5 lbs Total: -16.7 lbs Total hours fasted: 412:23

Note: I liquid fast, so coffee with a bit of cream in the morning I allow. Also a protein shake towards the middle of the day.

Also lost 2 1/2” from my waist and 3” from my hips!

It’s not as big of a weight loss as others, but I feel like it is so good for my first month! I’m expecting I’ll probably lose slower in the following weeks, but I am just happy to finally be almost under 200 for the first time in 3 or 4 years! Now I want to focus on increasing my activity.

If anyone has any advice or recommendations for other subs or forums ( or any kind of material honestly ) I would very much appreciate it!

Hey friends

Have any of you experienced pre diabetes? If so what were some changes you made to make sure you don't get diabetes? I'm tracking my food intake, fasting for 13-17 hours a day and actively trying to cut out the carbs. I'm definitely not as active as I should be so getting regular exercise is my next step.

Completely exhausted after eating OMAD

Hi Guys,

36 male. Been OMAD’ing for almost a year now. 2000 tdee and eat around maintenance or slightly less sometimes. Focus on a keto style OMAD, protein and animal fats with a light carb amount under 75g typically. I’ve noticed all of a sudden in the last couple of months, I’ve been completely wiped out about 30min after my meal. Almost like my body is too busy processing all the food that it shuts down everything else. I want to just fall asleep in that moment and become useless. If I wait another hour it usually passes and goes back to normal. This is particularly hard for me because I eat dinner with my family then need to be active with my 3 young kids right after. My energy level is fine throughout the day while I’m fasting, so it’s just after I eat.

Any idea what this could be and why it started happening all of a sudden, on an otherwise successful OMAD plan? I chew food properly, eat vegetables first, drink plenty of water, get fiber. Blood sugar spikes? This didn’t even happen to me at the beginning when I first started almost a year ago, so makes no sense why it’s happening now. Same diet, no processed foods, avoid processed sugars, I don’t get it.

When I eat 2MAD or 3MAD on my “cheat weekends” i don’t crash the same way. So I’m probably getting a huge insulin spike with the single meal. 2MAD was harder to maintain on my tdee, I’d overeat, so I’m trying to avoid that if I can. I find OMAD easier anyway.

I was thinking last resort, I can switch to eating an hour or two before bed, but dinner time is much more social and better for my lifestyle. I feel I’d have a really hard time waiting all day and night to eat too.

Would really appreciate any feedback or suggestions you guys might have.

Thank you!

A disgusting I.F benefit.

Apologies in advance for this.

In my third week of 20:4 IF and eating clean in my window.

The scale isn’t moving much, but my clothes are fitting better and my face is hella slimmer.

I work some pretty gnarly shifts which have fucked up my circadian rhythm.

In a working week I can start the week starting work at 2am and swap around to finishing at 3/4am by the end of the week.

This left me with a permanent low level upset stomach and pretty much diarrhoea all the time.

However the past two weeks: no upset stomach and I am winning the Bristol stool chart for the first time in years!

What a time to be alive!

16:8 IF and morning workouts

Hello.

I am looking for a bit of advice from people that workout in the mornings while fasting.

I have been on 16:8 IF for a couple of months now, specifically my eatimg wondow is 11am to 7pm and is as follows as I work 9am - 5:30pm:

  • 9am drink lemon/ginger/turmeric warm water or peppermint tea
  • 11am breakfast and black coffee
  • 2pm small snack and black coffee
  • 6pm dinner
  • 7pm peppermint tea

I am currently planning to start working out. I enjoy morning workouts but not on ungodly hours like 5 or 6 am. As I work at 9 (WFH) I can wake up at 7 and be at the gym by 0730, workout for 1hour and by back home in time for work. I am planning to go to the gym 3 times a week, mainly for weightlifting and cardio.

My questions are the following:

  1. As I want to workout during the fasting window, should I drink electrolytes or just have water? I know the majority of electrolyte drinks found in stores have loads of sugar, any recommendations that won't ruin fasting?

  2. Do I need to change my eating window to be right after my workout or is it okay to still fast untill 11am?

My goal is to get a bit more toned and lose some fat. IF has somewhat helped a bit this past year with weight loss but I think exercising will also help a bit more.

Any advice will be appreciated 😊 (sorry for any typos)

IM fasting routines

Hey my friendly and motivational people of this group. I (37 M) have just started with intermittent fasting (SW 265) and am about 3 ish weeks in. So far it’s been a fairly easy transition (my first week was 16-8 and then I moved into a 20-4 mainly due to my work schedule. I have a GW of 185 and currently after 2.5-3 weeks I’m down 9 lbs.

Now my question is, is there any benefit to altering the fasting schedule? Is it a good idea to move the eating window around from week to week? Or day to day even? Through the week I have no problem fasting for most of the day, but, when the weekend comes I have a hard time especially because I have a family who isn’t partaking on this journey…they have no need to being kids and all lol.

If it matters for this query, I’ve been doing some light exercise over my lunch break, 3-5 times a week by going for a 3-5km walk and this would be about 16 hrs into my fast with my current schedule.

Any advice one the weekly scheduling would be very much appreciated. Thanks!

Been riding on a high all day

I started IF 6 weeks ago, initially doing 16:8 which naturally moved to 18:6 and now onto 20:4. As of this morning I've lost 15 lbs and am so ecstatic! I was doing IF really solidly and found it relatively easy to move into for the first 4 weeks but then really struggled with PMS so I let myself off a little, lengthened my eating window and didn't beat myself up for eating chocolate. I also stopped weighing myself because I knew it would go up and I didn't want to get disheartened.

Anyways after a week of being less strict, I "reset" with a 24hr fast and have since been doing 20:4. This morning I felt confident enough to weigh myself, thinking that it might be back to where I was before. I was shocked to find I had lost another 5lbs since the end of April. I'm now about half way to my goal weight and almost back to what I weighed in 2019. I feel a million times better, way less bloated, eating healthier, moving more and drinking far less. This is the first "diet" that I've been able to stick to and I feel like it is something I will be doing for the long term. Weirdly I find complete restriction during the fasting periods much easier than food group restriction in other diets.

That was all :) just felt like I wanted to tell someone as I have largely kept it private from friends and family.

Stats: SW: 180 lbs, CW: 165, GW: 147. 5'5 32F. Doing CICO, approx 1200-1500 cals a day
