The only thing I did in November was update my credit card expiration date which I regret. Try our recipes, each a healthy dinner idea full of nutrition without skimping on taste. Grabbing a few pairs of jeans in a size 10, and one in a size 8 just for fun, I dashed into the dressing room. In fact, I have to remind myself to get everything in. While their Basic plan worked for me for me, they have several options to choose from. Which of these diet programs are worth your money? I wished to lose more.

Two of the panda's most distinctive features, its large size and round face, are adaptations to its bamboo diet. Anthropologist Russell Ciochon observed: This lower metabolic rate and a more sedentary lifestyle allows the giant panda to subsist on nutrient poor resources such as bamboo. The morphological characteristics of extinct relatives of the giant panda suggest that while the ancient giant panda was omnivorous 7 million years ago mya , it only became herbivorous some Pandas eat any of 25 bamboo species in the wild, such as Fargesia dracocephala  and Fargesia rufa.
Bamboo leaves contain the highest protein levels; stems have less. Because of the synchronous flowering, death, and regeneration of all bamboo within a species, the giant panda must have at least two different species available in its range to avoid starvation. While primarily herbivorous, the giant panda still retains decidedly ursine teeth, and will eat meat, fish, and eggs when available.
In captivity, zoos typically maintain the giant panda's bamboo diet, though some will provide specially formulated biscuits or other dietary supplements. Pandas will travel between different habitats if they need to, so they can get the nutrients that they need and to balance their diet for reproduction. They took note of their foraging and mating habits, and analysed samples of their food and feces.
The pandas would move from the valleys into the Qinling Mountains and would only return to the valleys in autumn. During the summer months bamboo shoots rich in protein are only available at higher altitudes which causes low calcium rates in the pandas and during breeding season the pandas would trek back down to eat bamboo leaves rich in calcium. Although adult giant pandas have few natural predators other than humans, young cubs are vulnerable to attacks by snow leopards , yellow-throated martens ,  eagles, feral dogs, and the Asian black bear.
The giant panda is a terrestrial animal and primarily spends its life roaming and feeding in the bamboo forests of the Qinling Mountains and in the hilly province of Sichuan. Social encounters occur primarily during the brief breeding season in which pandas in proximity to one another will gather. Pandas were thought to fall into the crepuscular category, those who are active twice a day, at dawn and dusk; however, Jindong Zhang found that pandas may belong to a category all of their own, with activity peaks in the morning, afternoon and midnight.
Due to their sheer size, pandas do not need to fear predators like other herbivores. They can therefore be active at any time of the day. Pandas communicate through vocalization and scent marking such as clawing trees or spraying urine. For this reason, pandas do not hibernate , which is similar to other subtropical mammals, and will instead move to elevations with warmer temperatures. Though the panda is often assumed to be docile, it has been known to attack humans, presumably out of irritation rather than aggression.
Initially, the primary method of breeding giant pandas in captivity was by artificial insemination , as they seemed to lose their interest in mating once they were captured.
The normal reproductive rate is considered to be one young every two years. Giant pandas reach sexual maturity between the ages of four and eight, and may be reproductive until age Copulation time is short, ranging from 30 seconds to five minutes, but the male may mount her repeatedly to ensure successful fertilization. The gestation period ranges from 95 to days. Giant pandas give birth to twins in about half of pregnancies.
The mother will select the stronger of the cubs, and the weaker will die. The mother is thought to be unable to produce enough milk for two cubs, since she does not store fat.
For three to four hours, the mother may leave the den to feed, which leaves the cub defenseless. One to two weeks after birth, the cub's skin turns gray where its hair will eventually become black. A slight pink color may appear on cub's fur, as a result of a chemical reaction between the fur and its mother's saliva.
A month after birth, the color pattern of the cub's fur is fully developed. Its fur is very soft and coarsens with age. The cub begins to crawl at 75 to 80 days;  mothers play with their cubs by rolling and wrestling with them. The cubs can eat small quantities of bamboo after six months,  though mother's milk remains the primary food source for most of the first year.
The interval between births in the wild is generally two years. In July , Chinese scientists confirmed the birth of the first cub to be successfully conceived through artificial insemination using frozen sperm. Attempts have also been made to reproduce giant pandas by interspecific pregnancy by implanting cloned panda embryos into the uterus of an animal of another species.
This has resulted in panda fetuses, but no live births. In the past, pandas were thought to be rare and noble creatures — the Empress Dowager Bo was buried with a panda skull in her vault. The grandson of Emperor Taizong of Tang is said to have given Japan two pandas and a sheet of panda skin as a sign of goodwill. Unlike many other animals in Ancient China , pandas were rarely thought to have medical uses. The few known uses include the Sichuan tribal peoples' use of panda urine to melt accidentally swallowed needles, and the use of panda pelts to control menses as described in the Qin Dynasty encyclopedia Erya.
Zouyu is a legendary "righteous" animal, which, similarly to a qilin , only appears during the rule of a benevolent and sincere monarch. It is said to be fierce as a tiger , but gentle and strictly vegetarian, and described in some books as a white tiger with black spots. Puzzled about the real zoological identity of the creature captured during the Yongle era, J. Duyvendak exclaims, "Can it possibly have been a Pandah? The comparative obscurity of the giant panda throughout most of China's history is illustrated by the fact that, despite there being a number of depictions of bears in Chinese art starting from its most ancient times, and the bamboo being one of the favorite subjects for Chinese painters, there are no known preth-century artistic representations of giant pandas.
The West first learned of the giant panda on 11 March , when the French missionary Armand David  received a skin from a hunter. The first Westerner known to have seen a living giant panda is the German zoologist Hugo Weigold , who purchased a cub in Kermit and Theodore Roosevelt, Jr. In , Ruth Harkness became the first Westerner to bring back a live giant panda, a cub named Su Lin  which went to live at the Brookfield Zoo in Chicago.
In , five giant pandas were sent to London. Gifts of giant pandas to American and Japanese zoos formed an important part of the diplomacy of the People's Republic of China PRC in the s, as it marked some of the first cultural exchanges between the PRC and the West. This practice has been termed "panda diplomacy". By , however, pandas were no longer given as gifts. Since , because of a WWF lawsuit , the United States Fish and Wildlife Service only allows a US zoo to import a panda if the zoo can ensure the PRC will channel more than half of its loan fee into conservation efforts for the giant panda and its habitat.
The issue became embroiled in cross-Strait relations — both over the underlying symbolism, and over technical issues such as whether the transfer would be considered "domestic" or "international", or whether any true conservation purpose would be served by the exchange. However, when Ma Ying-jeou assumed the presidency in , the offer was accepted, and the pandas arrived in December of that year. Microbes in panda waste are being investigated for their use in creating biofuels from bamboo and other plant materials.
The giant panda is a vulnerable species , threatened by continued habitat loss and habitat fragmentation ,  and by a very low birthrate, both in the wild and in captivity.
The giant panda has been a target of poaching by locals since ancient times and by foreigners since it was introduced to the West. Starting in the s, foreigners were unable to poach giant pandas in China because of the Second Sino-Japanese War and the Chinese Civil War , but pandas remained a source of soft furs for the locals.
The population boom in China after created stress on the pandas' habitat, and the subsequent famines led to the increased hunting of wildlife, including pandas. During the Cultural Revolution , all studies and conservation activities on the pandas were stopped.
After the Chinese economic reform , demand for panda skins from Hong Kong and Japan led to illegal poaching for the black market , acts generally ignored by the local officials at the time.
Though the Wolong National Nature Reserve was set up by the PRC government in to save the declining panda population, few advances in the conservation of pandas were made, owing to inexperience and insufficient knowledge of ecology. Many believed the best way to save the pandas was to cage them. As a result, pandas were caged at any sign of decline, and suffered from terrible conditions. Because of pollution and destruction of their natural habitat, along with segregation caused by caging, reproduction of wild pandas was severely limited.
In the s, however, several laws including gun control and the removal of resident humans from the reserves helped their chances of survival. With these renewed efforts and improved conservation methods, wild pandas have started to increase in numbers in some areas, though they still are classified as a rare species.
In , scientists reported that the number of pandas living in the wild may have been underestimated at about 1, Previous population surveys had used conventional methods to estimate the size of the wild panda population, but using a new method that analyzes DNA from panda droppings , scientists believe the wild population may be as large as 3, Furthermore, in response to this reclassification, the State Forestry Administration of China announced that they would not accordingly lower the conservation level for panda, and would instead reinforce the conservation efforts.
The giant panda is among the world's most adored and protected rare animals, and is one of the few in the world whose natural inhabitant status was able to gain a UNESCO World Heritage Site designation.
The Sichuan Giant Panda Sanctuaries , located in the southwest province of Sichuan and covering seven natural reserves, were inscribed onto the World Heritage List in Not all conservationists agree that the money spent on conserving pandas is well spent.
Chris Packham has argued that the breeding of pandas in captivity is "pointless" because "there is not enough habitat left to sustain them". In , Earthwatch Institute , a global nonprofit that teams volunteers with scientists to conduct important environmental research, launched a program called "On the Trail of Giant Panda". This program, based in the Wolong National Nature Reserve, allows volunteers to work up close with pandas cared for in captivity, and help them adapt to life in the wild, so that they may breed, and live longer and healthier lives.
Pandas have been kept in zoos as early as the Western Han Dynasty in China, where the writer Sima Xiangru noted that the panda was the most treasured animal in the emperor's garden of exotic animals in the capital Chang'an present Xi'an. Not until the s were pandas again recorded to have been exhibited in China's zoos. Chi Chi at the London Zoo became very popular. This influenced the World Wildlife Fund to use a panda as its symbol. A New York Times article  outlined the economics of keeping pandas, which costs five times more than that of the next most expensive animal, an elephant.
San Diego's contract with China was to expire in , but got a five-year extension at about half of the previous yearly cost. Cryptozoologists use Giant Pandas as an example of an animal recently discovered by science. Skeptical cryptozoologist Joe Nickell , notes that since Giant Pandas were known to local people, they qualify as cryptids.
Also, fossil evidence shows that pandas were once widespread, including the two million year old skull of Ailuropoda microta . From Wikipedia, the free encyclopedia. For other uses, see Panda disambiguation , Panda Bear musician , and Giant panda disambiguation.

Try sparkling water with a twist of lemon or lime instead. Cut down on creamers and sweeteners you add to tea and coffee. Buy unsweetened iced tea, plain yogurt, or unflavored oatmeal, for example, and add sweetener or fruit yourself. Check labels and opt for low sugar products and use fresh or frozen ingredients instead of canned goods.
Be especially aware of the sugar content of cereals and sugary drinks. Avoid processed or packaged foods like canned soups, frozen dinners, or low-fat meals that often contain hidden sugar. Prepare more meals at home. You can boost sweetness with mint, cinnamon, nutmeg, or vanilla extract instead of sugar. Refined Carbs and Sugar: Find healthy ways to satisfy your sweet tooth.
Instead of ice cream, blend up frozen bananas for a creamy, frozen treat. Or enjoy a small chunk of dark chocolate, rather than a milk chocolate bar.
Start with half of the dessert you normally eat, and replace the other half with fruit. And cocktails mixed with soda and juice can be loaded with sugar. Choose calorie-free mixers, drink only with food, and monitor your blood glucose as alcohol can interfere with diabetes medication and insulin.
Being smart about sweets is only part of the battle. Sugar is also hidden in many packaged foods, fast food meals, and grocery store staples such as bread, cereals, canned goods, pasta sauce, margarine, instant mashed potatoes, frozen dinners, low-fat meals, and ketchup. The first step is to spot hidden sugar on food labels, which can take some sleuthing:.
Manufacturers are required to provide the total amount of sugar in a serving but do not have to spell out how much of this sugar has been added and how much is naturally in the food. The trick is deciphering which ingredients are added sugars. Aside from the obvious ones— sugar, honey, molasses —added sugar can appear as agave nectar, cane crystals, corn sweetener, crystalline fructose, dextrose, evaporated cane juice, fructose, high-fructose corn syrup, invert sugar, lactose, maltose, malt syrup , and more.
A wise approach is to avoid products that have any of these added sugars at or near the top of the list of ingredients—or ones that have several different types of sugar scattered throughout the list. The trick is that each sweetener is listed separately. The contribution of each added sugar may be small enough that it shows up fourth, fifth, or even further down the list.
But add them up and you can get a surprising dose of added sugar. The most damaging fats are artificial trans fats, which make vegetable oils less likely to spoil. The healthiest fats are unsaturated fats, which come from fish and plant sources such as olive oil, nuts, and avocados.
Omega-3 fatty acids fight inflammation and support brain and heart health. Good sources include salmon, tuna, and flaxseeds. Good, Bad, and the Power of Omega-3s. Two of the most helpful strategies involve following a regular eating schedule and recording what you eat.
Your body is better able to regulate blood sugar levels—and your weight—when you maintain a regular meal schedule. Aim for moderate and consistent portion sizes for each meal. Start your day off with a good breakfast. It will provide energy as well as steady blood sugar levels. Eat regular small meals—up to 6 per day.
Eating regularly will help you keep your portions in check. Keep calorie intake the same. To regulate blood sugar levels, try to eat roughly the same amount every day, rather than overeating one day or at one meal, and then skimping the next.
Exercise can help you manage your weight and may improve your insulin sensitivity. You can also try swimming, biking, or any other moderate-intensity activity that has you working up a light sweat and breathing harder. Dieting Tips that Work. Learn how to lose weight and keep it off.
If your last diet attempt wasn't a success, or life events have caused you to gain weight, don't be discouraged. The key is to find a plan that works with your body's individual needs so that you can avoid common diet pitfalls and find long-term, weight loss success.

The Diabetes Diet Healthy Eating Tips to Prevent, Control, and Reverse Diabetes People with diabetes have nearly double the risk of heart disease and are at a greater risk of developing mental health disorders such as depression.
What's the best diet for diabetes? The biggest risk for diabetes: You are at an increased risk of developing diabetes if you are: A woman with a waist circumference of 35 inches or more A man with a waist circumference of 40 inches or more Calories obtained from fructose found in sugary beverages such as soda, energy and sports drinks, coffee drinks, and processed foods like doughnuts, muffins, cereal, candy and granola bars are more likely to add weight around your abdomen.
Myths and facts about diabetes and diet Myth: You must avoid sugar at all costs. You have to cut way down on carbs. A high-protein diet is best. Eat more Healthy fats from nuts, olive oil, fish oils, flax seeds, or avocados Fruits and vegetables—ideally fresh, the more colorful the better; whole fruit rather than juices High-fiber cereals and breads made from whole grains Fish and shellfish, organic chicken or turkey High-quality protein such as eggs, beans, low-fat dairy, and unsweetened yogurt Eat less Trans fats from partially hydrogenated or deep-fried foods Packaged and fast foods, especially those high in sugar, baked goods, sweets, chips, desserts White bread, sugary cereals, refined pastas or rice Processed meat and red meat Low-fat products that have replaced fat with added sugar, such as fat-free yogurt Choose high-fiber, slow-release carbs Carbohydrates have a big impact on your blood sugar levels—more so than fats and proteins—so you need to be smart about what types of carbs you eat.
