Do You Burn More Calories in Winter or Summer

Filed under: Weight Loss, Fitness, Exercise, Diet, Burn Calories — admin @ 1:01 am

You burn fewer calories when you exercise in cold weather than you do when it’s hot. The hotter it is, the more extra work your heart has to do to prevent you from overheating. More than 70 percent of the energy produced by your muscles during exercise is lost as heat. So the harder you exercise, the hotter your muscles become. In hot weather, not only must your heart pump extra blood to bring oxygen to your muscles, it must also pump hot blood from your heated muscles to your skin where heat can be dissipated.

On the other hand, in cold weather, your heart only has to pump blood to your muscles and very little extra blood to your skin to dissipate heat. Your muscles produce so much heat during exercise that your body does not need to produce more heat to keep you warm. So your heart works harder and you burn more calories in hot weather.

This information should not discourage you from exercising when it’s cold, because staying in shape is a year-round proposition. However, it may help to explain why so many people find the pounds creeping on in the wintertime, even when they stay active.

18 Ways to lose Weight Without Going On a Diet

Filed under: Weight Loss — admin @ 2:06 pm

To lose one pound of body weight in a week, a person must consume about 500 fewer calories than he or she burns each day. Here are 18 ways to lose weight without going on a diet.

1. Instead of drinking orange juice at breakfast, eat a whole orange. You’ll save about 45 calories.

2. Make your breakfast omelette with four egg whites plus 1/4 cup egg substitute. Replace regular bacon with Canadian bacon to save even more calories.

3. Switch from whole milk to nonfat or lowfat milk. Use sugar substitute instead of sugar in your morning coffee or latte.

4. At lunch, use mustard instead of mayonnaise on your sandwich to save 100 calories (per tablespoon) . Eliminate the cheese and save 100 more calories.

5. Instead of a Big Mac and large fries, go for a plain hamburger and a small french fry and save a whopping 590 calories!

6. Don’t eat potato chips at snack time. Have an apple instead for less calories plus the added benefit of more fiber.

7. Substitute diet cola or iced tea for your usual soda. You’ll save 150-200 calories per drink.

8. Eat every two to three hours with smaller portions. Don’t skip breakfast! Eating small, frequent meals keeps blood glucose levels stable and minimizes the impulse to overeat.

9. Eat more healthy snacks like dried fruits and nuts, fresh fruits, cut up veggies or yogurt.

10. Substitute whole grain foods for white bread, rice and cereals. You will not only cut fat and calories, but whole grains have been proven to reduce the risk of colon cancer by increasing the fiber that your body needs.

11. Saute meat, chicken and vegetables in broth instead of butter. And speaking of butter: replace it with nonfat sour cream on baked potatoes.

12. Instead of Caesar salad, substitute a dinner salad with nonfat salad dressing.

13. Do you love pasta? Have spaghetti with marinara sauce instead of fettuccini with Alfredo sauce. You’ll save at least 500 calories!

14. When you’re going out with friends, watch your alcohol intake. Instead of using Coke or Seven-Up with your drinks, choose tonic water or seltzer.

15. Restaurants are notorious for their huge serving sizes. Eat only half of your dinner and save the rest for lunch tomorrow. Or simply share the meal with a friend.

16. Get moving. Walk to the store instead of driving. Walking is the best exercise you can do to lose weight.

17. Get more walking time by replacing coffee breaks with exercise breaks. Also use half of your lunch break to take a brisk walk with a co-worker.

18. Swim, swim, swim. By swimming for just an hour you can burn 500 calories. You’ll also end up with a firmer, more toned body.

You don’t have to go on a strict diet to lose weight. Change to more sensible eating habits and start moving your body by walking, swimming or bicycle riding. You’ll be rewarded by good health and a fit body.

Maximize Results with a Perfect Workout

Filed under: Workouts, Weight Loss, Fitness, Exercise — admin @ 1:19 pm

When it comes to exercise, routine is your enemy. Your body should constantly be forced to guess what crazy new workouts you decide to put yourself through. This practice inhibits your muscles and physiological systems from gradually adapting to the demands you place on them. While some training programs address this adaptation by completely changing the workout program’s set, rep, and exercise routine every 4-8 weeks, I’d like to explain a less common idea: changing the daily intensity. For the purposes of this article, I will be incorporating three different intensities - high, medium, and low. With a routine like this, you won’t have to worry about switching your workout mode every few weeks, as long as you constantly plug and play new exercises.

Think of your body as a car’s engine. Low intensity would involve idling at a stoplight. Your primary fuel is fat, and your actual caloric expenditure is low. There is still a good amount of blood flow to exercising muscles, but the actual cardiovascular stress and fiber tearing in the muscle is minimal. You are not breathing hard, conversation with your fellow gym-goers is fairly non-stressful, and muscles really don’t burn all that much. Such an intensity is great for a recovery workout, or for a strength/power workout with long rests between sets. You could potentially go for several hours at this intensity and still be able to do another workout the next day.

You’re cruising down the highway when in medium-intensity mode. Breathing and heart rate become a bit more rapid, you can feel a burn in the working muscles, and the primary fuel is a mixture of fat and carbohydrate. Mental focus is typically a little higher than low-intensity mode, and the workout itself is challenging, but not daunting. You can usually exercise the next day, but typically want to avoid stressign the same muscle groups.

In high-intensity mode, you are working at a 100%, all-out effort. Muscles are constantly burning, breathing and heart rate are very high, carbohydrate is the main fuel source, and caloric expenditure is through the roof (as is your post-workout metabolism). The entire body is tired after this type of workout and you generally need about 24 hours of rest of very easy work afterwards. Many times, it can be difficult to mentally force yourself to *begin* one of these kind of workouts, although once you launch into and the adrenaline kicks in, energy levels naturally rise.

The key to the sample training program outlined below that the low, medium and high intensities are stacked so that your body optimally responds and optimally recovers from each workout. So here is a sample daily-intensity based workout for a fairly frequent 6 day work-out routine.

Day 1 (i.e. Monday): high-intensity cardio intervals (shorter, i.e. 20 minutes) with high-intensity full body resistance training (longer, i.e. 45 minutes), incorporating back-to-back sets, challenging weights, difficult training scenarios, and short rest periods.

Day 2: low-intensity cardio, long and steady (i.e. 45 minutes+), with no lifting. Good day for an outdoor workout, like a hike or easy bike ride.

Day 3: high-intensity cardio intervals with medium-intensity full body lift, incorporating primarily body weight training. Great day to experiment and try new exercises and/or group exercise classes.

Day 4: low-intensity cardio, long and steady (i.e. 45 minutes+), with no lifting.

Day 5: medium-intensity cardio (shorter, i.e. 20 minutes) with low-intensity lifting (longer, i.e. 45 minutes),. For the lifting, incorporate heavier weights with longer rest periods, and focus on slow and controlled movements with perfect form and little to no ballistic activity.

Day 6: high-intensity cardio (longer, i.e. 45 minutes) with high-intensity full body resistance training (shorter, i.e. 20 minutes). Great day to try the Weekly Trainer Challenge, plus some extra cardio.

Day 7: active rest. Does not equal couch+bon-bons. Get up and move around, but just don’t stress your body too much.

There you have it. This type of exercise routine allows for sufficient recovery after the high-intensitiy periods, while still allowing for maximum caloric burning and efficient workouts. There are many different ways you could approach such a routine (in terms of exercises, specific cardio intervals, etc.).
