Hi,
This is a time of year when many of us find it even more difficult than usual to watch our diets and keep up our exercise program. All I can say is - do whatever you can to stick with it. Backsliding can be very depressing, and it can be very difficult to make up ground that you previously gained as far as weight loss and/or strength improvement. Remember all the great benefits that come with proper weight levels and physical fitness. If you need some encouragement or information on the many benefits of health related fitness just go back to my site, and look around.
For those of you who celebrate Thanksgiving, have a nice holiday, but try not to eat too much.
Food for Thought
Life is not a skill sport. It is a game that anyone can play and play well.
Feature Article - Fats, Proteins, and Carbohydratesby Thomas D. Manfredi, MSThe main building blocks of good nutrition that people are always talking about are fats, carbohydrates, and proteins. Let’s briefly describe what these nutrients are.
Protein is found in plant and animal sources. Animal proteins include meat, poultry, fish, eggs, and dairy products. Plant proteins include beans, nuts, breads and cereals.
Carbohydrates are the body's main source of energy and they generally come in the form of starches and sugars. Common starch sources of carbohydrates are wheat, rice, potatoes and corn. Sugars are also carbohydrates because they provide energy in the form of calories, but they don't provide any additional nutritional value. Although sugars do not provide nutritional value, complex carbohydrates such as whole grains, fruits and vegetables are valuable to the body because of the vitamins, minerals and fiber they provide.
Fats are also a valuable source of energy to the body and serve many other necessary functions as well. Saturated fats, sometimes referred to as ‘bad fats,' contribute to the production of cholesterol and LDL. Meat and poultry, whole or reduced-fat milk, and butter are main sources of saturated fatty acids. Trans fatty acids act like saturated fatty acids in the body. Trans fatty acids come from processed vegetable oils like margarine and shortening. Unsaturated fats, also known as ‘good fats’ , help lower LDL levels and decrease risk of heart disease. Different forms of unsaturated fats include monounsaturated fatty acids, which mainly come from vegetable oils like canola, olive and peanut and polyunsaturated fatty acids, which come from safflower, sunflower, corn, and flaxseed oils. Polyunsaturated fatty acids are also the fats found in seafood.
There are many different opinions around as to the best combination of these all important nutrients. It is not my intention here to go into all the various points of logic regarding the ratios of protein, carbohydrates, and fats. I simply want to point out that I feel you should be cautious of any diet plan that recommends an unusually high or low ratio of any of these items. This type of diet is often referred to as a “fad diet”. Although these diets can sometimes help a person to lose weight quickly, the results are very often short lived. Even worse, some fad diets have been found to be dangerous to our long term health.
I am in the process of adding a number of pages of information regarding diets and nutrition to my site. If you are interested, check back periodically on my home page at fitness-after-50.com and click on the “Diets” tab.
Teleclasses
I will be announcing upcoming teleclasses in this section in
the future. Questions and AnswersQ: What are antioxidants and why are they important? A: ntioxidants are molecules found in the body and in certain foods. The body makes enough antioxidants to neutralize free radicals generated by normal metabolism. Free radicals are unstable molecules that damage normal cells. When additional free radicals are created by stress, poor nutrition, environmental toxins, smoking, etc., the body cannot “keep up” with the free radicals. These excess free radicals are then "free" to damage normal cells.
Some of the most common nutrients that contain antioxidants are the vitamins A, C, and E. In order to help our bodies fight off extra free radicals, we should make sure we eat a balanced diet that includes sufficient quantities of A, C, and E. About Our Services
