Eating one meal per day?

onmyway214

I was wondering if anyone has ever done the one meal per day diet and had success. I have done alot of research and have found alot of science behind this method. I am in search of success stories or personal experience with this. If you can share with me, that would be great!!! Thank you!!!

I have never heard of it but it's making me hungry just thinking about it! I think I would keel over and die :sick:
Be interesting to see if anyone has done it.

There is at least one group on this site and several threads: intermittent fasting

The science is thermodynamics. Eat less than your TDEE and you will lose weight. Timing of meals is purely personal preference and has no bearing on weight loss. It's about sustainability. If you can do one meal a day and get your required caloric intake, go for it! If not, don't fret about when to eat, only that you eat your allotted calories to remain in a deficit and feel satiated throughout the day and don't risk binging or relapsing on old habits

I do 1MAD works for me. I love it, wish I had found it years ago. Search the groups for intermittent fasting .

I do this.

It's 5-10 courses and takes me nearly all day to finish.


Really? Scientific research?
Colour me skeptical.

Sounds miserable. Just eat less calories than you burn and eat them whenever you want.

Agreed

Deficit is key. Eat 1000 times a day or once...just eat at a deficit and you will lose weight. Will one method lose weight faster than the other? nobody knows...everybody is different.

Hi! I fast during Ramadan and gain weight every year. While there is a proven science to intermittent fasting, the weight loss is not sustainable and, more importantly, is not healthy. I don't know your situation, but what if you spread out whatever you were going to eat for that one meal over several hours? Though I personally do not support that low of a calorie intake, it could be a good way to trick your metabolism. Water is also your best friend in that situation. I'm happy to brainstorm eating plans with you if you'd like! Shoot me a message.

I am doing it. I started it about 7 days ago. I am already down 6 lbs. The only downside to it is when you are out and about, it's easy to fall off track. My eating window is from 1 pm- 4 pm and I eat around 3 usually. Yesterday, I was out and didn't eat until 8. If I had not, I would've seen that one and a half pound drop this morning:( But I'm going to be back on track today. It works. You should try it.

Hi! I fast during Ramadan and gain weight every year.

Because you're eating more than you are burning. Ramadan fasting and its effects on metabolism and body fat have been studied extensively. Here's a study that showed the participants lost fat and retained muscle while fasting during Ramadan: http://www.ncbi.nlm.nih.gov/pubmed/19164831

While there is a proven science to intermittent fasting, the weight loss is not sustainable and, more importantly, is not healthy.

Is there any "proven science" that it's not sustainable and not healthy? Or is that just your opinion? P.S. You can't "trick" your metabolism by eating several times a day.

I eat one meal per day. I've sustained my weight loss for 3 years. I'm perfectly healthy.

There is no magic to eating all your calories in one meal. It doesn't flip some fat burning switch. I recommend it to people who are very busy during the day, don't want the hassle of trying to eat multiple meals at work, and prefer to eat larger meals. I do not recommend it to people who aren't going to accurately log their calories and will use their one meal to justify eating as much as they want or to people who are just going to sit around, brooding about food all day. If it doesn't make your life easier, you're not going to stick with it. But if you think it will work for you, let me assure that it CAN be done, and it is absolutely healthy, provided you are ultimately eating the same amount and same types of food you would be eating if you spread your meals out throughout the day.

Strong 10th post? :ohwell:

Yeah, actually weight loss with intermittent fasting is very sustainable. I have been on it for almost exactly a year now, and am down 27 lbs. At one point I was down 30+ lbs, but I'm currently in a slow body recomp.

There's no real science behind it, just pseudo-science. Putting aside what should be an obvious negative impact on your blood sugar levels, daily physical/mental functioning, etc, sure you will lose weight if that one meal contains less calories than you are burning in a given day ... but you will also lose weight by eating at that same deficit and splitting that one meal into 5 meals and without the costs to your health and ability to properly function.

Question - What is the "obvious negative impact on your blood sugar levels, daily physical/mental functioning, etc..."? And how does eating 5 meals a day avoid any "costs to your health and ability to properly function" that one meal a day doesn't?

I had a friend that was eating 1 big meal a day. He was also bike riding to work everyday about 8 or 10 miles. He lost a lot of weight but wasn't very healthy. Constantly tired, lack of focus, and one day passed out in the parking lot. Still refused to believe that it was from the lack of eating. Would say "i've always ate one meal a day..."

The fatigue and brain fog from hunger is one thing to be wary about. While one meal a day may be sustainable, fatigue and brain fog isn't sustainable.

Some people can work on one meal per day while others cannot. I certainly am one of those who can't!

Try it, but be careful about over-exerting yourself during your "trial" period. Then slowly increase your exercise levels and see how you do. Keep some quick snacks nearby just in case.

Best of luck!

Hi! I fast during Ramadan and gain weight every year.

I work with a ton of people who fast during Ramadan- and every single one of them shuts down their daily life. There is one kid who refuses to even take the stairs because 'he's fasting'.- it's 3 small flights.
I can't say this is everyone- but it's a common trend here and I can absolutely 100% guarantee he is going to gain weight this year- because he's using it as an excuse to do NOTHING at all. I am embarrassed for him.

You gained weight because you are still over eating.

While there is a proven science to intermittent fasting, the weight loss is not sustainable and, more importantly, is not healthy.

that's the thing- you have to figure out what's sustainable for you- some people this works. And if it works great. For me it doesn't- but I know several people who pretty much eat like that and it's great.

Also just to be clear- IF is not JUST about weight loss- it's about meal timing- and the two are not intrinsically connected.

suremeansyes

I wish I could do it because my one meal would be EPIC.

However, I just have to settle for two semi-epic meals.

Ummm...no

I do this most days because I just naturally prefer to. I can put a lot of food away at one time, I just have to make sure it's the kind of food that will keep me going through into the next day.

MrGonzo05

If you want to do it, rock on. You may find it workable. However, whatever "science" you found supporting it is likely flawed. I also reckon with no science whatsoever that it would also have some disadvantages. Such as reduced exercise performance, reduced protein synthesis, social awkwardness of avoiding food then pigging out, and bad breath. And if it works for you, you're going to want to tell everybody about it all the time, and it will annoy them.

My husband only eats one meal a day because he says he is only hungry once a day. However: 1) His one meal is huge, more like all three meals at once. 2) He runs about 6 miles a day, but despite that and only eating once a day he is gaining weight. 3) His hands shake a lot, which his doctor said was caused by his eating habits. 4) He turns into a slug in the evenings and can barely get off the couch.
Sounds like it works for some people and not others. I know I could never do it.

suremeansyes

And if it works for you, you're going to want to tell everybody about it all the time, and it will annoy them.

HAHAHA, yes. Probably why I don't have any friends. People can only take so much "advice" (read: gushing about results) and complaints about having to buy new clothes.

My mom just started doing this. But she has lots of good snacks throughout the day and her one meal is always a healthy one.
Like she has apples, almonds, low fat yogurt, a banana for snacks and then for her meal when she gets off work something like a chicken salad. She's just started and says in a week she's lost 3 pounds this week and says she has more energy and honestly is not starving. She walk or bikes at night for exercise also.

This is absolultely horrible for your blood sugar!! You're just asking to gain weight on a diet like this in the long run. I advise against it. I eat 5 to 6 times a day, but they are small meals mostly (lunch or dinner are usually my biggest meals out of the day). Eating small amounts regularly throughout the day regulates your blood sugar keeping in it the "fat burning zone." Of course you still have to eat the right things to keep your blood sugar from spiking / crashing. Complex carbs are a great way to do this... fruits and veggies.... fiber and good fats... just saying.

I really think it's all a mental/lifestyle thing. If eating one meal a day makes sense to you and it's going to make it easier to stay within your calorie limit, go for it. If it's going to make your life miserable and more difficult, don't bother. You can lose weight no matter how many meals you eat.

I don't really think the timing of your meals will impact weight loss. That is really based on your TDEE and what your deficit is. However, I have been following an intermittent fasting protocol and it can provide some specific benefit when working on body composition, especially when combined with strength work. So in that sense, you may experience results in terms of higher percentage of fat loss, but TDEE and cut will still dictate loss overall. I'm down to about 20% BF using this approach.

I typically eat my meals within an 8 hour window. I don't have any medical issues that require me to eat more frequently, and since losing weight my blood sugars are far more stable anyway so a 16 hour "fast period" (which includes when I am sleeping) just isn't a big deal for me. I do my workouts in a fasted state (cardio and strength, each 3x per week) with no problems. However, I did not start following this protocol until I was within 10 lbs or so of my goal, so my experience might have been different if I had done this when I still had a lot more to lose.

I would not recommend this approach if you are eating at a significant deficit. I think that one of the reasons it works well for me is that I am not trying to make 1200 calories sustain me for that period; I would really not be able to follow this plan at that level. But if you are already inclined towards fewer meals, just make sure you are minding your TDEE and give it a try.

I need 2500 calories a day, no way I can get that in one meal. And even if I could, I have mild hypoglycemia and need to eat at regular times.

I like doing this because I seem to feel better during the day. It's not unhealthy because I get my calories in. I saw the 1mad diet and that's where I got my idea from. I decided to do the "cheat" days after I get further into my weight loss. They actually say that keeping nothing on your stomach during the day adds to the digestion process and keeps your pancreas inactive so it's not producing insulin which means what you eat it used as energy to digest and to get through the next day and none is being stored. So when you need energy the next day, your body burns fat.

I did this today (not intentionally though; just happened to do it lol) within a three hour time span around 10 am to 1 pm and quite frankly, I feel the same. Not hungry either for the rest of the day and I didn't have to worry about food and had more time to study and do other stuff. Hmmm maybe i should do this more often... Well, if you stick to something for a while your body gets used to it but like others have mentioned, blood sugar can rise and crash quite quickly with that much food at one time. Idk, you should try it out for awhile to see if it's for you.

It does not matter when we eat.
By preference, I eat one or two meals a day. It is working for me.
