Diet changes - can they make you want to eat less? zephyron
  Jul 23 2008 03:23

Starting about a month ago I changed my diet to cut out a lot of bad stuff (fast food, sweets, sodas, excessive amounts of cheese, etc.) and put in some healthier stuff (broccoli, tuna without mayo, soups, chicken, etc.) in order to start losing weight.  I haven't cut out the goodies completely, but I wasn't planning on it, I am just having one small treat a day as opposed to several or two large ones or whatever.

Anyway, after the first few days of adjusting to the new foods and reduced intake (I have no idea what I was eating before, but I have lowered my intake to ~2000 calories/day which is definitely less than I was eating before) and greatly increasing my activity (cardio exercises 3 times a week for 30+ minutes, strength training 2-3 times a week as opposed to almost nothing) which has definitely helped.  I have already lost about 10lbs and my pants are fitting better than before - in fact I need a belt for most of them now!

So, to the point of this topic - I know I wouldn't be able to eat what I was eating before (at least in volume, I could probably eat some high-calorie low-volume things and get to where I was before calorie-wise) but today it seemed like I was struggling to get to the 2000 calorie mark, in fact I was almost done at about 1700 today.  Which is odd, because I did a lot of walking today (about an hour) not included in my weekly stuff mentioned above, it was due to hanging out with friends and walking around the city.  So I thought I should be eating MORE today because of the extra burn.  And I don't think it was because of eating more volume in less calories, because I had a smaller lunch today than normal, around my usual time, and was still not hungry later when I normally am.

Is this something I should be concerned about or is it probably a fluke?  It hasn't happened before, in fact usually I am at least a little hungry at several points during the day when I normally eat meals or small snacks.  I guess just see what happens tomorrow and if it happens again worry about it then?  I'm just so new to this, never really paid attention to what I ate before, and really didn't care about working out... but it's felt really good this past month so I don't want anything to go wrong.  Any input/advice would be greatly appreciated.

I don't think anything's wrong - more than likely it's a one-time thing for you.  Sometimes it's just that day  - ie, I know sometimes when I'm super-busy I lose my appetite a bit, and when it's really hot out I don't feel like eating much.  Or maybe you're coming down with the flu (I hope not!!) You're right about the volume thing, if your stomach size is shrinking as a result of smaller portions, pushing more food down it will be uncomfortable. 

Glad you're doing well on the whole - sounds like you have a really healthy routine - and hope you're back to normal tomorrow :)

Sounds to me like you're doing well and things are starting to "normalise" for you. Keep up the good work. Good on you for making lifestyle changes.Smile

I've always felt that when you're eating junk food, you're getting so few nutrients that your body craves more and so you overeat.  If you're eating good quality foods, you're getting more nutrients in a smaller volume of food, so you don't need as much.

I have no idea if that has any scientific merit at all but it always made sense in my head lol.

Either way, it's a good feeling so enjoy!  And great job so far!

Yes, I find that when I eat better (fresh vegetables, whole foods, non-junk), I COMPLETELY lose my cravings for junk I used to crave, such as sugar and ice cream. It's kind of nice. Eating junk like that only makes you crave it more, because it makes your blood sugar spike and crash continuously. It's very hard on your body.

Btw, you mentioned tuna, and I would warn you against eating it regularly, or in fact, eating it at all. The mercury levels in it are extremely dangerous these days. 

Here's some info on it:

Yeah, I heard about that.  I don't eat it too often, but I do like it.  And when I do eat it I don't eat that much.

Well I'm definitely hungry today, so we'll see how it plays out later.  Hopefully things will be back to normal.  Thanks for all the responses so far.

I find that when i'm working out hardcore i really lose my appetite...so i try to get in most of my calories during work/the day bc i usually workout at night (after my post-work nap) and then afterwards i'm rarely ever hungry enough to eat a real dinner--i do make sure i get i high protein snack or some fruit to replenish after working out, but i'm just not hungry.

 Hmmm my physicians both eat tuna on a regular basis (2X a week).....they say the mercury is less prevelant in tuna compared to other fish.  I eat it twice a week myself!  But then again, I won't be getting pregnant.....

I'm not scared of the mercury, I'm scared of all the other toxic waste that is dumped into the river from the oil refineries and chemical companies in my neighbourhood.  It's all in the fish.

Well, it seems to have been a one day thing.  My appetite was back to normal today.  Unfortunately I fell off the exercise train temporarily but today was so crappy (pouring rain, dark and dreary) that I just didn't feel like doing anything anyway.  So I'll just make up for it tomorrow.  (Really yesterday with the walking sorta covered anything I was going to do today, besides lift weights, so I think I'm OK.)

I remember learning about something that is in fat that makes you want to eat more. It has a name but I don't remember it. That is why you typically can eat more junk, especially fast food , than you can in a regular meal. That's what I remember anyway.  Well I just looked that up and can't find it, I found a bunch of articles on a taste bud that detects fat. The study showed that (tested on rodents) the tongue contains a taste bud for fat, it was once only believed that you could distinguish sweet, salty, sour, and protein. So I guess in the study the rats that had this taste bud preferred fatty foods when offered and they other rate somehow did not have this, did not prefer fats. So although not yet known to be true, in humans one could believe that the more fat you consume the more you crave to eat it. However I read another article that promoted eating regular fats in your diet because they make you feel full longer. This article discourage low-fat diets stating that you would be more hungry and end up eating less .

As far as the whole tuna conversation above, may I please add that the recomendation to consume no more than 7 oz of fresh water fish per week is for pregnant women. The amount of mercuery is not really as dangerus to a grown adult, but it could potentially be very harmful on a developing fetus or your child. There aren't documented cases of mercury poisening in the united states. Only a small number of potential cases that were mild.

I also would like to say without offense that just because you may be a vegetarian doesn't really give you the right to misinform people about their food. The FDA measures the amount of mercury in foods and it would not be able to be sold if the content was too high. As far as dumping the mercury was the biggest problem with this. Companies were dumping inorganic mercury into the water, that is also now regulated. So I'm not being rude or mean, just factual, Before you give someone advice make sure that it applies.

Ok so sorry that was long, just wanted to get my point out there.

Sorry, sbatt, not sure if you're referring to my post or orchid's above.  I didn't mean to suggest that commercially-available fish in the United States was not tested for safety.  My point was that the fish out of the river near where I live is most certainly NOT fit for human consumption.  Public health authorities in the area have confirmed this.  There are oil refineries and a number of chemical companies sited along the river.  The fish have tumours and look inedible/unappetising anyway.

Although I don't live in the U.S., I have a lot of respect for both the FDA and EPA and I think that their intentions are very good AND that they do a good job of keeping food safer in your country than most others.  Still, they can't always keep up with new problems as fast as they arise.  I have read a number of other studies about fish that concern me relating to the health of babies of women who ate a lot of fish from PCB-contaminated waters pre-conception.  I can't interpret the science for anyone else, but it might be worth looking up if it's something you're worried about.
