    How do I lose weight in my 40s?

    The same way everyone does, eat fewer calories than you burn until you reach your goal. Sometimes being 40 makes it less convenient or more difficult to lose or maintain weight because of the lifestyle we settle into. In other words, our ability to move throughout the day as much as when we were younger causes us to burn fewer daily ca...Read More

    What should I do if I've overeaten?

    Make up for it. Over-eating is simply giving your body more fuel than it needs. Therefore, you can burn the extra fuel by moving more the next day or two and by eating fewer calories. However, if you find yourself eating large quantities of food because of stress, loneliness, boredom or other emotional...Read More

    Is it true that some foods cost more calories to digest than they provide?

    I believe the Mayo Clinic researched this topic and found that the act of chewing sugarless gum at a certain rate burned a few more calories than the calories in the gum but we don't actually eat and digest the gum, it's the chewing activity that burns the calories so at this point the answer is...Read More

    How does the body lose weight?

    The body loses weight when fewer calories are taken than the body uses for our metabolism activity and digesting food. This forces the body to tap into its stored energy for fuel, that being adipose tissue, fat, stored carbohydrates called glycogen and protein or lean body mass. Simply put, if food...Read More

    Will I need extra iron when I start working out?

    Yes, if you’re not getting enough. Women who are capable of becoming pregnant are prone to iron-deficiency due to not getting enough through food and because of monthly losses due to menstrual cycles. Women ages 19 to 50 years need 18 mg per day and those over 50 years need 8 mg/day. If you're pregnant,...Read More

    Should I change my diet if I want to breastfeed?

    First of all, I commend you for choosing to breastfeed because human milk is the optimum nutrition for your baby.  Human milk contains more antibodies, immune factors, growth factors, digestive enzymes, and healthy fats than cow’s milk, and its protein ratio makes digestion and absorption easier....Read More

    Is there a type of iron that is better absorbed than others?

    Yes, heme iron found in lean meat, seafood and poultry is absorbed more readily than non-heme iron contained in enriched cereals, breads, spinach, beans and lentils. Having a food with vitamin C (tomatoes, tomato sauce, citrus fruits, peppers) helps increase iron absorption. Women who are capable...Read More

    Do I need more calcium because I am a woman?

    Women between the age of 51 and 70 years need more calcium than males due to lower estrogen levels after menopause. Lower estrogen levels results in decreased calcium absorption and increased calcium breakdown from bone. Therefore, the recommended daily allowance for this age group is 1,200 mg/day....Read More

    Do multivitamins contain gluten?

    Most probably don’t, but if so, it’ll say so on the label. Look for the fine print usually on the bottom where the product lists things it doesn’t contain such as gluten, dairy, tree nuts, etc.. Most Multivitamin and Mineral formulas (MVM) try to eliminate sources that people may have allergies to...Read More

    What is proper portion control?

    Portion control is eating the appropriate amount of food to maintain a healthy body weight. This is challenging in Western society since portions are typically much bigger than what we need to manage our waistlines.  Portion control is also eating the right number of calories for your body.
