is fasting good for health?
 
i am taking a nutrition class right now. today the instructor said that fasting is not good/beneficial for health, which i think is kind of odd. i've done some research online regarding fasting before, and the info. i gathered was that fasting is in fact good for your health, and if you fast one day a week, it can be really good for you. that makes sense to me because i think fasting gives your system a break. when animals are sick, they tend to fast and it seems to help them heal. does anyone have good info. on this topic? i need to do some research again, last time i looked up this info. was a couple of years ago.

I don't know but I personally believe that it is good to fast but only for a couple of days to clean your system and get the bad stuff out. However it depends how you do it, and it must only be a short time.

I think fasting is bad for you. Anytime you eat less the 1000 calories your system starts to break down, you lose muscle first because muscle requires the most calories to survive. Ten pounds of fat need hardly any calories to stay on your body; ten pounds of muscle needs lots of calories, so your body goes into survival mode and gets rid of muscle first. Each time you lose muscle, your metabolism slows, so you end up needing few calories then you did before. I always recommend people eat a little even when they are sick; to avoid losing muscle. Women, who go on starvation diets, are setting themselves up for failure. Your nutritionist is telling you about science and what scientific research has proven, she's not trying to sell you something. Remember, popular ideas aren't necessary truthful ideas. However, I don't think you should force a dog to eat during certain illnesses, for example, acute pancreatitis, at that point you are suppose to give the system a rest, but this isn't really the same as fasting.

yes, we learned about how you lose muscle first when you consume fewer calories than is required by your body. that was very interesting. the instructor told us that a lot of people like to lose weight rapidly, and they always gain it back, and the bad thing about that is your body gains more fat each time you do that. so you basically keep losing muscle and replacing it with fat everytime you lose weight rapidly and gain it back.

Yes the science is very clear on this, yet we humans keep looking for shortcuts. You have to remember the body is first built for survival, and when we limit food or water it goes into a different state, and tries to keep from losing any fat, because fat has kept us alive in times of famine. Each time you go through a starvation period, you body gets better at conserving fat. The first time you diet, you will lose weight the fastest, each successive attempt is slower, and weight comes back quicker each time.

i did some research, and i found out that fasting is not the best way to detox your system or to give your digestive track a rest. the best way is to do a juice fast or only eat veg and fruits for a day a week or a day a month. that way you are still giving your body a chance to detox because it doesn't have to work so hard to digest the hard to digest foods, but at the same time, you are giving your body the nutrients and fuel it needs.

i wonder what is the equivalent for dogs. how do you give their digestive system a break? :D

I'm doing the Lemon detox diet right now
 
and I'm on day 6 and feel great, I still exercise everyday so I shouldn't lose any muscle, I've lost 2 kg already and have 4 days to go, anyway I'm not doing it only to lose weight, I have been feeling bloated and unwell after eating for quite a while and decided the best option was to fast to clear my body of toxins and the formula I have every day is full of the minerals etc that the body needs to keep going, and it is filling enough not to make me feel hungry. I have had a lot of people saying it's bad but then I have had others that agree with the diet so I think only time will tell if I'm hurting myself. It's not a real fast but pretty close no solid food at all.

I do agree the fruit or vegetable diets can be healthful, but part of it is that we are removing some foods that I think are bad for us. I don't think white flours and simple sugars are good for us, and can make us feel sluggish. I don't necessarily believe we should detox ourselves; a healthy liver should do that. I don't think we need to clean out our intestines or give them a rest. Do you "rest" you heart or lungs? Why rest the intestines? I think eating fiber is good for the intestines, and I'm a big believer in that, but I don't think you want to give your digestive system or your dogs digestive system a break. Just eat healthy every day, or as healthy as you can. Just like the old saying goes "A apple a day, keeps the doctor away," I think what it really means is a healthy poop a day, keeps the doctor away. :D

people gain weight over the years, but when they want to lose weight, they want to lose it quickly. i've read an article before of a person dying from losing too much weight too quickly because fat cells trap toxins that are in our bodies, and that person lost all the weight and all that toxin was released into her system at once. :eek:

it's human nature to want to be lazy (aka. efficient :p) people WANT to believe there is a quick fix, and marketers know that, therefore they just tell people what they want to hear; what they want to believe.

Yep, and the weight loss industry is a multibillion dollar industry. The best advice is to eat healthy and exercise, your body will find it's perfect weight, you might not like it, but it will be healthy for you.

Dont ever stop eating! It's very bad for your body. Instead, make your portions smaller. Losing mucsle mass is not good because when you begin to eat normal your body will store it as fat. That fat will come on with a vengeance! Notice, when an animal is dying it will stop eating. Drink 6 to 8 bottles of water a day to hydrate and no coffee or chocolate! Very dehydrating! Good Luck YorkiePuppie!

Yay for nutrition classes!

I don't have the scientific answer (although my nutrition teacher would say if it is peer reviewed, it's on pubmed and everything else is hear-say). I don't think it's going to hurt to fast once in awhile. But I really don't think it's good for you. Just think of the amount of carbohydrates the brain needs a day...130g. How are you getting that if fasting (even averages out over a week) if you are fasting for a week? If people don't feel well when they eat and thus want to take a break, then perhaps there is a medical issue going on or they are eating the wrong things... And a lot of people fast (aka detox) to lose weight. Well, such a reduction in calories is going to result in weight loss, but there are probably healthier ways to go about it. We need nutrients to survive and withholding them doesn't seem like a good thing to be doing to our cells!

Nutritionist wanted to make a point to the class. So he first went over the vitamins recognized in science: A, B, C, D, E, K. Then he pulls up a site for vitamin O. lol. So much on the internet isn't science at all. It's opinion.

Absolutely yes! It is a common tradition among religious group.
It has health benefits
