500 CALORIES/DAY pros and cons??

mommabenefield

Its just two days people. She will be fine if its just two days, geez.

It doesn't matter. Eating 500 calories a day is not healthy, it's drastic and unhealthy. That's is twice below anyone's BMR.

Besides this, you starve yourself for two days, start eating normally, and then you gain it back. Where's the health in that?

Well I went to jail over a weekend this last summer and ate about 500 calories a day because the food was so gross I couldn't stand it.I lost 1 lb a day and never gained it back.(Total 5 lbs)I didn't do much in jail read alot barely could walk back in forth in my cell no energy ,but the food was so bad I have to meditate...Hope I never go there again.

What do you mean muscle kicks in the third day?

I'm guessing she means muscle atrophy starts becoming an issue after 72 hours of fasting.

Wow, you sure did stir up a **** storm here! 2 days you should be fine, it will probably be difficult after binge eating for a while, but it wont harm you. Try not to weigh yourself while doing it, because it's mostly water weight. But eating less will make your stomach smaller so you get full on little over time!

There must be something you can do with your life apart from making ridiculous posts on myfitnesspal? It's a cry for help but we can't help you. All the best with everything.

why would you post if you didn't want to help then.

thanks anyway..

Because of this:

3. No Promotion of Unsafe Weight-Loss Techniques or Eating Disorders

a) Posts intended to promote potentially unsafe or controversial weight loss products or procedures, including non-medically prescribed supplements or MLM products will be removed without warning.
b) Profiles, groups, messages, posts, or wall comments that encourage anorexia, bulimia, or very low calorie diets of any kind will be removed, and may be grounds for account deletion. This includes positive references to ana/mia, purging, or self-starving. Our goal is to provide users with the tools to achieve their weight management goals at a steady, sustainable rate. Use of the site to promote, glamorize, or achieve dangerously low levels of eating is not permitted.

Which is quoted from here: http://www.myfitnesspal.com/welcome/guidelines

Besides this, eating 500 calories is ridiculous.

This sounds like intermittent fasting which btw not only healthy but clinical studies have shown that it does not decrease BMR. You can eat whatever you want as long as it's < 500 calories or <25% of your TDEE.

Must be. And, that's something we all want, right? :bigsmile:

:flowerforyou: Thanks for this!

While I don't recommend consecutive fast (or 500 calorie) days, alternate day or intermittent fasting is healthy and sustainable.
