Why Weight Training

Why does Time for Change Fitness promote resistance training?

Many people focus on calories alone. The slash and dash mentality develops destructive patterns, like extreme calorie cuts and/or excessive aerobics. This sets off an alarm-state in the body where the body sheds muscle tissue to lessen energy demands, and stores body fat as a survival response. Once this physiological state is reached, it becomes nearly impossible to lose any more weight no matter how many calories you cut or how much aerobic work you add. What you end up with is a person who is on a starvation level calorie count and performing excessive exercise, yet is still flabby.

The calories burned during an exercise session are relatively small compared to the amount burned during the other 23 hours of the day. Most fat oxidation occurs between training sessions, not during. This means your exercise sessions should primarily be geared towards building muscle and boosting your metabolism.

After a strength training session, the metabolic rate raises (the after-burn effect) for longer periods of time than after aerobic work (up to 48 hours). This is because all of the steps involved in the recovery process from strength training (satellite cell activation, tissue repair, protein synthesis, etc.) require energy (calories).

Coffee


COFFEE (kaw’fee)

Coffee is used to increase alertness, mood, exercise tolerance, and to enhance bronchodilation. Historically, coffee was administered by mouth for asthma, headache, and colds, or by rectum as an antidote for opium poisoning. It is used in herbal medicine to stimulate the appetite and facilitate digestion. Coffee promotes peristalsis and accelerates circulation. It may prevent onset of Parkinson’s disease and gallstones.

Coffee has quite a few drug interactions, including antacids, aspirin, beta-blockers, estrogens, hormonal contraceptives, and MAOI’s, so it is a good idea to research or talk to your pharmacist. As far as herbs are concerned, you should be aware of caffeine content, so that you do not over do it. Caffeine-containing herbs include cocoa, cola nut, guarana, and yerba mate. Coffee should not be combined with ephedra.

IMPORTANT TO YOUR DIET:

Caffeine may increase the excretion of calcium and magnesium.
Grapefruit juice may increase caffeine levels.

Caffeine intake can do the following:
1) increase free-fatty acid mobilization from fat cells, potentially sparing your body’s use of carbohydrate stores (glycogen) (these affects have led endurance athletes to use coffee as a performance enhancing substance)
2) stimulate the central nervous system
3) potentially increase blood pressure in non-habitual users
4) increase energy expenditure and thus is used as a common weight loss aid.

Harvard researchers calculate that downing one to three cups of caffeinated coffee daily can reduce diabetes risk by single digits. And having six cups or more each day slashed men's risk by 54% and women's by 30%.

Though scientists caution "more research is needed" their findings are similar to those in a less-publicized Dutch study. It's one of the latest of hundreds of studies suggesting that coffee may indeed be healthy, especially in higher amounts.

At least six large studies indicate that people who drink coffee on a regular basis are up to 80% less likely to develop Parkinson's, with three showing the more they drink, the lower the risk. Additional research shows at least two cups daily can reduce risk of colon cancer by 25%, cirrhosis of the liver by 80% and cut the risk of gallstones by nearly 50%.

Coffee may even offset some of the damage caused by other vices. Smokers and heavy drinkers who regularly drink large amounts of coffee have less heart disease and liver damage compared to those who don't.

Coffee is one of the most widely researched substances on the planet. Caffeine found in coffee and tea is the most common drug consumed in the world. Not everyone tolerates caffeine well, and it is easy enough to tell if you fall into that category as you will likely experience nervousness, sweating or simply an uncomfortable feeling. As long as it does not bother you - have a cup, two or three . . . and enjoy.

What affect does coffee have on one's overall nutrition status?

Answer:
As long as one does not have adverse reactions to coffee or stimulants, coffee may offer more health benefits than most other beverages when consumed in moderation (from one to six 8oz cups per day). Caffeinated coffee is predominately water with its main “active” ingredient being caffeine, which belongs to a class of compounds called methylxanthines. Methylxanthines are found in more than 60 species of plants including coffee, tea and cocoa plants. Coffee also contains very small (not necessarily significant) amounts of antioxidants and other substances.

"Overall, the research shows that coffee is far more healthful than it is harmful," says Tomas DePaulis, PhD, research scientist at Vanderbilt University's Institute for Coffee Studies, which conducts its own medical research and tracks coffee studies from around the world.
