calories for weight loss

I received the following question on dietitiancentral.com:

Message: Mrs. Andrews,
I am currently on a diet where I have been counting calories. I have read that it's said that for a woman of my size 5'7 275lbs that 1,200 calories is what I should take in. But in order for me to lose weight I neeed to cut 500 calories from my diet. Currently I have been taking in about 750-900 calories daily, but I also have started riding an excise bike which burns off another 200 calories. I have been losing weight and I haven't been having any symptoms such as leg cramps, dizziness, or any other issues. Is this a safe diet for me to on? Also I want to make eating healthy and exercising a new lifestyle for me, yes I am doing it to lose weight now but it's something I want to continue doing.

 

Thanks for your email.  I'm not sure where you read that your calorie level is 1200 per day as this is way too low for a woman of your height and weight.  Many magazines will suggest women "do not go below 1200 calories per day" as this is very difficult to adhere to and can potentially cause nutrient deficiencies.  It is very difficult to obtain adequate nutrition in such a low calorie level.  And, quite frankly, you will be starving!

 

You will likely lose weight on this diet, but it is not safe long term.  You may have lost some fat as well as protein (muscle) as well as water thus far.  It is dangerous to stay on a level this low as it may cause electrolyte abnormalities (potassium, magnesium, calcium), dehydration,  hair loss, dry skin, lightheadnesses, fatigue, etc.

 

A more appropriate level for you is about 1500 per day, which I suggest as you are exercising.  If your calorie level is too low, your metabolism will stall and eventually, you will stop losing.  In addition, you won't have much energy to exercise if you don't eat enough!

 

I suggest you look at choosemyplate.gov for a sample 1500 calorie meal plan.  You may obtain individualized help by finding an RD at www.eatright.org

 

Best of luck!

Fast food & obesity

I received this from a Lakota East student:

Ms. Andrews,

 

I'm Abbie VanFossen with the Lakota East Spark, and I would like to get your thoughts on the topic of a story that I am writing. The story focuses on Americans and their addiction to fast food, and how it has contributed to the obesity crisis. Any help you can give me would be greatly appreciated! I'll just include a few questions in this email to sve you as much time as possible.

 

Do you see the growing popularity of fast food in America?

Yes- it has become a staple in many homes.  Most families eat out at least 3 or more times/week, and some professions (such as truck drivers) eat fast food several times per day.

 

Why do you think Americans have come to rely on fast food?

Fast food is cheap, tasty (not to me, but to some) and convenient.  Also, many families believe their kids won't eat healthier options, so picking up fast food avoids hassles at the dinner table.

 

What aspect of American food culture do you think most contributes to to the obesity crisis the United States is experiencing?

This is multi-factorial.  Part of the obesity crisis is related to excess calorie consumption- from soda and other sweetened beverages, large portion sizes and high fat foods.   We're also a 'push button' nation.  We have remotes for everything, so our activity levels have seriously declined. Finally, many people don't think regular exercise as necessary.  People can't seem to commit time to exercise, but they have no problem watching 2 hours of TV per night or playing with electronic games and devices.

 

How much does portion size contribute to the high obesity rate in the United States, in your opinion?

Portion size of food obviously contributes to the high rate of obesity in the US.  In other countries, portion sizes are more reasonable and cultures to 'use' food to reduce anger, depression and other psychological conditions.  When people eat out, portion sizes are quite large, and they get used to that.  If they knew what a true serving size was, they'd be amazed at how much less they really should be eating.

 

Thank you so much for your time, I greatly appreciate it!

Carbs and blood sugar

Hi Lisa…hope all is well!  Ok…this is my question:  since I have 45 carbs for my meals and 30 for snacks…let’s just say I was still hungry after my 45 carbs…how long should I wait to eat something else?  I am hoping to get my glucose and fasting insulin test done in January with my physical…so I hope I have made some improvements!  This whole carb thing freaks me out!

Always happy to help.  As for the snacks/meals and timing, I'd say try to wait at least 3 hrs before eating something else.  You don't want to get into the habit of eating every 2 hours if possible.  Make sure you're including protein w/your meals and snacks.  It will help manage your blood sugar better and keep you feeling fuller longer.  Eggs, string cheese, nuts/seeds, natural peanut butter, etc are all great.  Edamame is another good high protein snack that's vegetarian.

Good luck w/your test!

Peanuts & Peanut Butter- yay or nay?

Lisa,

Is there such as thing as too much peanut butter/peanuts?  It is high in fat - but it is healthy fat, correct?  Should one still limit the amount that they eat?

Well, of course you can eat too much of anything!  But, in general, nuts are very healthy, although high in fat, calories and sodium (unless they are lightly salted or unsalted).  They contain mostly mono-unsaturated fat, which is heart healthy.  If you're watching calories, nuts and peanut butter are calorie dense, but also filling due to the protein & fat content.

With peanut butter- it is really best to get natural peanut butter (the type where the oil is on the top and you have to mix it in).  This type is typically made with nuts and/or salt ONLY and doesn't have any other added ingredients like palm oil, molasses, sugar, etc.

Palm oil, which is saturated, replaced trans fat in most peanut butters.  So, even if the label says "natural", it may have palm oil, which you don't want.  Saturated fat increases blood cholesterol, and a new study actually suggests it may affect fertility in men.  Drop the butter, too!

I would not pour the oil off on natural peanut butter, because then you're left with a clump of nuts that won't spread on a sandwich.  Instead, store the peanut butter upside down in your pantry before and after mixing it. Gravity will make the oil go to the bottom and make it easier to mix up each time.

Most natural butters will say "refrigerate after opening", which will make it more solid when you want to use it.  You can put it in the microwave for ~30 seconds to warm it up.  Honestly though, I don't put it in the frig. We go through PB so fast in my house that I'm not worried about contamination.

Hope that helps!
