Watermelon

The health benefits of watermelon include help with kidney disorders, high blood pressure, diabetes, heart care, heat stroke, macular degeneration, impotence and more!

Here are some health benefits of water melon:

Kidney Disorders: Watermelon contains a lot of potassium, which is very helpful in cleaning or washing off the toxic depositions in the kidneys. Moreover, it is helpful in reducing concentration of uric acid in the blood, thereby reducing the chances of kidney damages and formation of renal calculi in it. Added to these, being high in water content, it induces frequent urinating, which is again helpful for cleaning of kidneys. Also, the anti oxidants present in ensure good health of kidneys for a long.

High Blood Pressure: A good amount of potassium and magnesium, present in water melons, are very good in bringing down the blood pressure. The carotenoids present in them prevent hardening of walls of arteries and veins, thereby helping reduce blood pressure.

Prevent Heat Stroke: Watermelon is effective in reducing your body temperature and blood pressure. Many people in the tropical regions eat the fruit daily in the afternoon during summers to protect themselves from heat stroke. In India, you will find the fruit being sold by vendors in almost every street during summers.

Diabetes: Diabetes patients, who are supposed to have low energy and low sugar diet, often complaint about starving since they don’t get to eat their staple diet to their full, giving them a feeling of keeping half fed. Water Melons can be a good supplement for them. In spite of being sweet in taste, a thick wedge will give you very few calories, since ninety nine percent of its total weight is composed of water and roughage. Moreover, the various vitamins and minerals such as potassium and magnesium help in proper functioning of insulin in the body, thus lowering the blood sugar level. Arginine, another component found in water melons, is very effective in enhancing impact of insulin on sugar. Diabetes patients can also have curries, steaks, salads made from water melon rinds which are even lower in sugar.

Heart Care: Lypocene, a carotenoid found in abundance in water melon, improves cardiac functions. Beta carotene, known for its remarkable anti oxidant and anti aging properties, also keeps you young at the heart and prevents age related cardiac problems. The roughage in water melon and its very low energy, with help from vitamin-C, Carotenoids and potassium (potassium cuts the risk of a heart attack), help reduce cholesterol and keep your heart safe.

Macular Degeneration: Leave your worry of eyes on that beta carotene, that vitamin-C and those Lutein and Zeaxanthin. They will ensure protection of your eyes from macular degeneration. They are experts in that. These anti oxidants will protect your eyes from other age related ailments such as drying up of eyes and optical nerves, glaucoma etc.

Impotence: Arginine, present in water melon, is beneficial in curing erectile dysfunctions.

Other Benefits: Lypocene is found to be effective in preventing cancer, prostrate growth and repair damaged tissues. Water melon seeds are rich in good fats and proteins. Water melons also contain phytonutrients which have very good effect on the health and proper functioning of internal organs, eyes, secretion system etc.

Vitamin D may boost heart health during weight loss

Supplements of vitamin D may improve cardiovascular health during weight loss, without impacting on how many pounds are shed, suggests a new study.

Writing in this month’s issue of the American Journal of Clinical Nutrition, German researchers report that a daily dose of vitamin of 83 micrograms per day had lower levels on triglycerides and markers of inflammation like tumour necrosis factor-alpha (TNF-alpha).
"The results indicate that a vitamin D supplement of 83 micrograms/d does not adversely affect weight loss and is able to significantly improve several cardiovascular disease risk markers in overweight subjects with inadequate vitamin D status participating in a weight-reduction program," wrote the authors, led by Armin Zittermann from the Clinic for Thorax and Cardiovascular Surgery in Bad Oeynhausen.

With obesity rates still high – not only in developed countries but also, increasingly, in newly wealthy emerging markets, there is considerable attention to ways to trim down waistlines. The results of the new randomised, double-blind, placebo-controlled trial indicate that vitamin D supplements may be useful as a means of boosting heart health during weight loss.

The details on D

Vitamin D refers to two biologically inactive precursors - D3, also known as cholecalciferol, and D2, also known as ergocalciferol. The former, produced in the skin on exposure to UVB radiation (290 to 320 nm), is said to be more bioactive.

While our bodies do manufacture vitamin D on exposure to sunshine, the levels in some northern countries are so weak during the winter months that our body makes no vitamin D at all, meaning that dietary supplements and fortified foods are seen by many as the best way to boost intakes of vitamin D.

In adults, it is said vitamin D deficiency may precipitate or exacerbate osteopenia, osteoporosis, muscle weakness, fractures, common cancers, autoimmune diseases, infectious diseases and cardiovascular diseases. There is also some evidence that the vitamin may reduce the incidence of several types of cancer and type-1 diabetes.

On the downside, the researchers noted that participants receiving the vitamijn D supplements did experience an average 5.4 per cent increase in their levels of LDL-cholesterol.

Intermittent fasting : short fasts for weight loss vs. traditional diets

How Drastic Reduction of Calories for Limited Periods of Time Compares to Other Plans

In an effort to make losing weight—and keeping it off—easier, researchers are studying what happens to the body when people eat next to nothing every few days.


Dieting books in the U.K. and elsewhere have used these studies as a springboard to tout the benefits of intermittent calorie restriction, such as the 5:2 Diet, which suggests five normal eating days and two restricted ones.
Some research shows that this more radical-sounding approach may be a struggle at first but ends up being easier to stick with compared with the typical route of cutting calories each day. Some animal studies suggest it also offers other health benefits, including cognitive improvements.
Many questions remain. For one, it isn't clear whether the very-low-calorie element of the diet confers health benefits in humans, or if the diet simply helps people eat less and lose weight temporarily, like with daily calorie restriction. The effects on metabolism and long-term effects on nutrition and health haven't yet been studied in humans.
Mr. Leite's meal includes one pound of ground turkey, six eggs and a whole avocado.

It also isn't known how much people need to hold back on their restriction days, or how many days a week to restrict is optimal. Changing eating and exercise routines typically leads to an average weight loss of about 5% of initial body weight, and usually only temporarily, studies have found.
Animal research by the government's National Institute on Aging has shown the strategy of alternating days of eating regularly, known as intermittent fasting, appears better at improving cognitive functioning and maintaining muscle mass. Animals following a more typical reduced-calorie diet did not fare as well.
Preliminary evidence in humans suggests that a similar pattern of intermittent calorie restriction appears to lead to weight loss in the short-term. Eating much less on some days and normally on others is as or more effective than reducing one's calories to between 1,200 and 1,500 calories daily, though continued research is needed, scientists say. (Men and women between 31 and 50 respectively need about 2,200 and 1,600 daily calories, according to the U.S. Department of Agriculture.)
Mark Mattson, chief of the laboratory of neurosciences at the National Institute on Aging in Baltimore, and colleagues have been studying intermittent fasting in animals for years. In their studies of older mice and rats and those with Alzheimer-like conditions, the ones that alternate between days of eating and fasting appear to be protected from cognitive impairment or even show signs of reversal of previous impairment compared with those with daily diet restrictions.
They have also found that these animals appear to maintain more lean mass as they get older. Animals and humans tend to lose muscle and gain fat as they age.
The thinking is that fasting for periods of as short as 16 to 24 hours seems to induce a state of mild stress in the body. The brain releases additional neurotrophic proteins that help stimulate and support the growth of neurons and other cells, heightening their responsiveness and activity. Just as exercise makes muscles stronger, fasting makes the brain stronger, Dr. Mattson says. The body chemicals produced by fasting and exercise also could help boost people's moods.
In humans, most of the study focuses not on true alternate-day fasting, because researchers weren't sure that humans would be able to adhere to that regimen, but on intermittent restriction, usually between 500 and 650 calories a day for two or three days a week, interspersed with days of regular eating.
Paul Hussain, 41, has been trying intermittent calorie restriction on his own for about a year. The lawyer, who splits his time between London and Geneva, was overweight, had diabetes and was experiencing stomach pain related to polyps and ulcers in 2012, he says. He began by trying calorie restriction two days per week, but found it didn't help him, in part because he had a difficult time fasting on those two days. He decided to try alternate-day restriction instead.
After an adjustment period of about four weeks, where he was hungry and "angry, grumpy and shouting in the house," he has settled into his routine. He eats about 600 calories a day on his "fasting days," often lentil soup and couscous with chicken. On his "feast days," he eats whatever he wants. He has lost about 50 pounds and no longer needs to take medication for his diabetes. The stomach ulcers have disappeared, he says.
His new diet can affect his social life, he says. If he meets friends on his fasting days, he will look at the menu ahead of time and pick out a low-calorie option. Nonetheless, sometimes friends will say they feel bad that he isn't eating with them.
Researchers say that like Mr. Hussain, most people studied are able to adhere to the new regimen after the initial 10 to 30 days.
"We think that once the people get adjusted to the diet—it's a big change to a diet—it is easy to adhere to," Dr. Mattson says. "If you know that tomorrow you can eat normally, you can make it through today."
Michelle Harvie, a research dietitian at the Nightingale and Genesis Prevention Centre at the University Hospital South Manchester, conducted a recent study looking at intermittent vs. daily calorie restriction in overweight women with a history of breast cancer. Participants were divided into groups and instructed to eat a diet for three months in a way that reduced their typical calorie intake by about 25%. The first group ate only low-carbohydrate foods for two consecutive days, while the second was limited to two straight days of low-carbohydrate, low-calorie foods. The third group restricted calories daily.
The two intermittent restriction groups lost twice as much weight as the chronic restriction group, but the intermittent groups didn't differ from each other. In addition, more people in the intermittent groups lost weight: 65% of intermittent restrictors, compared with 40% in the chronic restriction group. The study was published in the British Journal of Nutrition in April.
It's unclear whether intermittent calorie restriction improves health better than daily calorie restriction, however.
A key to successful intermittent calorie restriction is to make sure that people don't overeat on the days when they aren't fasting. Surprisingly, they don't seem to, says Krista Varady, an assistant professor in kinesiology and nutrition at the University of Illinois at Chicago who has conducted multiple human studies on intermittent calorie restriction.
They eat only about 110% on non-fasting days, which doesn't compensate for the amount they restricted the day before. People also report that they get used to the routine and actually can't eat as much in general, even on their non-fasting days, Dr. Varady says.
Jayson Leite, 39, of Mountain House, Calif., designed his own intermittent restriction strategy after hearing about Dr. Varady's research.
After trying numerous diets that didn't work, he now eats one meal daily, typically between 1,200 and 1,600 calories, then not again until at least 24 hours later. In the nearly five years he been eating this way, he has dropped to 137 pounds, from 205 pounds. The change has been so striking that friends often express disbelief. "One friend is convinced I have different genes," Mr. Leite says with a laugh.

16:8 – a form 
of intermittent fasting (IF) where you eat nothing
for 16 hours a day, then cram all your calories into the other eight. 

Example:
  • I skip breakfast (cups of coffee are fine) and then tear into half a rotisserie chicken at 11am, with baby spinach and a wholegrain roll. That weighs in at about 800kcal with more than
 50g of protein (almost 90% of my RDA).   I eat again around 3pm:  sushi or
 a sandwich. Dinner is down by 7pm and then the 16-hour stopwatch begins again.
