I do intermittent fasting as described by MPLANE37, but that is not true fasting in that my calories are NOT lower than they would be if I were eating 6 small meals/day. My calories are exactly the same, just eaten closer together, and I do it for the reasons he mentions. True fasting, where you just don't consume food, is very dangerous and not a good way to lose weight as it can invite all sorts of health problems. There is no need for it. Eat healthy, the right amount for you, and that is pretty much all you need to do.

Number one rule to losing the fat and keeping it off is to lose it slowly. Losing fat very fast is very dangerous as previous posters already mentioned, but even if it were not so dangerous, you would not be able to change your unhealthy habits in a short time so you would gain it all back.

The more reasonable approach is to give yourself at least a year, set up a not too ambitious goal weight, as well as a not too ambitious weekly calories burned goal and start losing the fat.

On a side note, people who practice caloric restriction for longevity do practice alternate day fasting. They eat one day without counting calories but only whole foods, and one day they eat nothing, and only drink water. That way, on the average they go into caloric restriction of a certain degree. Their metabolism slows down, and apparently this also slows down aging. Obviously they don't do it for fat loss, but over time they lose both fat and lean body mass.

Body builders also do intermittent fasting, and it is extremely effective in reducing the fat layer over the muscles. Muscle building does not happen without also gaining fat, so after several months of building muscle, they do intermittent fasting, which burns a lot of fat with little to no muscle loss, simply because body does not have time to notice the lack of calories and slow down the metabolism.

Fasting is not a healthy way to lose weight....a person needs good nutrition, vitamins and minerals...Yes, it is harmful to your body, especially the kidneys and liver have a really hard time when fasting, because you're stopping the intake of nutrients, that help you clean your body up!....could be that as soon as your fast is over, everything you eat will be stored as fat.....and really mess up your metabolism.....

you would be better off eating raw or steamed veggies, fruits and 2-3 serving of protein daily, incorporating walking into your daily routine and moving every 20 minutes...

Sodium, sugar and carbs stall weight loss and also give you cravings. Give up all bread, fried foods, reduce the intake of starch and sugar from which the glucose is made, and to fill the void with another fuel, i.e. fat. Avocado's, Olive Oil, Fatty fish..eat low carb as when you resort to a low-fat diet which is based on carbohydrates, your body is forced into the fat-building mode and not the fat-burning mode.

Eat only low carb fruits are pears, peaches, plums, cherries, apples, kiwi, all kinds of berries.
Salad greens are very low in calories (maybe 10 calories a cup) and try to get the best nutrition from your greens. Romaine is high in nutritional value and so is spinach. So skip the iceberg lettuce. Kale is also good and loaded with fiber. The darker green, the better.
Add 2 ounces of Roast chicken, turkey, tuna, sardines, shrimp, crab, cheese, hard-boiled egg, sunflower seeds, sesame seeds, walnuts, chickpeas, to your salads for variation and some raw carrots, califlower, brocolli, Cucumber, tomato, radish, peppers, cabbage, onion, olives, celery and avocado. Vinegar helps control blood sugar so always have a vinegar & oil salad/ I try to get at least a small one in daily.

Good Luck!

The previous posters have given you some great advice. Fasting is not a healthy (or permanent) method of weight loss, so we would not recommend it.

Although people DO fast for several reasons-- before medical procedures, or for religious reasons, for example-- I agree with Unident that it's a seriously bad idea to use fasting as a means to weight loss. Here's an "Ask the Experts" on fasting: www.sparkpeople.com/community/ask_the_expe
rts.asp?q=63


I've had to fast before medical procedures, and I can tell you from personal experience that after the fast is over, it is difficult not to want to eat ANYthing that isn't nailed down or moldy. So in essence you end up worse off than before you even started.

Eating nutrious foods within your calorie range, stepping up the exercise, and drinking lots of water are much better ways to get your metabolism on track.

Sorry, you've been fed some misinformation.

Except for medically required before a procedure where it's necessary, there is no positive benefit whatsoever to fasting at all.

It is unhealthy and can be potentially dangerous. Any weight lost is mostly water, muscle and other lean body mass that you actually want to keep. It doesn't accelerate losing actual "fat" from the body.

Instead of fasting entirely, why not try another mind trick? Zero junk food, 8 glasses of water ("water" only), and at least 25g of fibre daily for one solid week. This will be all that your body needs to help "detox" and restore it to a healthy balance - and any weight you lose will almost certainly be much more "fat" than if you had fasted!

(Absolutely NEVER use laxatives for weight loss or combine them with a fast. That is incredibly dangerous).

Hi :)

I would like to do a fast at some point but I'm not sure about how to do it.
Has anyone any info?
Like how long should one do it? Do I have to take any sort of laxatives first? How long before my metabolism will start slowing down? How fast will I lose weight?

Thanks!
