Diet Guru – Healthy Weight Loss

People who complain they have no time to exercise may soon need another excuse. Some experts say intense exercise sessions could help people squeeze an entire week’s workout into less than an hour. Those regimens — also called interval training — were originally developed for Olympic athletes and thought to be too strenuous for normal people.

But in recent years, studies in older people and those with health problems suggest many more people might be able to handle it. If true, that could revolutionize how officials advise people to exercise — and save millions of people hours in the gym every week. It is also a smarter way to exercise, experts say.

“High-intensity interval training is twice as effective as normal exercise,” said Jan Helgerud, an exercise expert at the Norwegian University of Science and Technology. “This is like finding a new pill that works twice as well … we should immediately throw out the old way of exercising.”

Studies on intense training have been published in sports medicine journals and have largely been based on young, healthy people. Experts say more studies are needed on how older and less fit populations handle this type of exercise before it can be recommended more widely.

Intense interval training means working very hard for a few minutes, with rest periods between sets. Experts have mostly tested people running or biking, but other sports like rowing or swimming should also work.

Helgerud recommends people try four sessions lasting four minutes each, with three minutes of recovery time in between. Unless you’re an elite athlete, it shouldn’t be an all-out effort.

“You should be a little out of breath, but you shouldn’t have the obvious feeling of exhaustion,” Helgerud said.

In Britain and the U.S., officials recommend that people get about 2 1/2 hours each week of moderate exercise. Those guidelines target a mostly sedentary population and are intended to help with weight control and heart health, not boosting fitness levels, increasing strength or endurance.

Some experts have cautioned that ordinary people shouldn’t substitute their regular exercise routine for intense training.

“There isn’t enough evidence to say people should do one or the other,” said Gary O’Donovan, a sports and exercise expert at the University of Exeter. “Any bout of exercise has the potential to improve your blood pressure or lower your cholesterol, and it doesn’t necessarily have to be intense.”

Still, O’Donovan said more intense exercise would probably produce better benefits.

Helgerud says the time people spend in the gym could be slashed dramatically if they did interval training instead. He said officials have been too afraid of recommending intense training for fear it would be too much for some people.

“I’m much more afraid of people not exercising at all,” he said. “Inactivity is what’s killing us.”

When compared to people on a normal exercise routine, like jogging, research has shown those doing interval training can double their endurance, improve their oxygen use and strength by more than 10 percent and their speed by at least 5 percent. Even studies in the elderly and in heart patients found they had better oxygen use and fitness after doing interval training.

Still, experts advise people to consult a doctor before starting any fitness program.

For Adamson Nicholls, a 36-year-old Londoner and martial arts enthusiast, interval training is a way to boost his endurance so he can outlast sparring opponents. “It’s a shortcut to explosive fitness,” he said, adding the training resulted in snappier and heavier punches.

Using interval training, Nicholls got into top shape last year in about six weeks with weekly 45-minute sessions. He estimates the same level would have taken about three months via regular training.

Experts say that’s because intense bursts of activity are precisely what the body needs to build stronger muscles. Traditional workouts lasting an hour or more simply don’t push the body enough.

“A lot of the (benefits) from exercise are due to a stress response,” said Stephen Bailey, a sports sciences expert at the University of Exeter. “If you disturb your muscles, there’s an imbalance created and your body will start signaling pathways that result in adjustments.”

Bailey said intense bursts of exercise help the body to convert one type of muscle fiber into another type that uses oxygen more efficiently and is capable of exercising a lot longer. Even though interval training only takes a few minutes, its effects last for hours.

“You’ve exercised at such a high intensity that you’re going to create a massive disturbance in your muscles,” Bailey said.

That creates a higher metabolism for several hours afterward, which the body will bring down by burning fat and carbohydrates.

“This is definitely the way forward to save time on your exercise,” Nicholls said. “The results are worth it.”

The brain uses carbohydrates for energy and omega-3 fatty acids for the formation of its cell structure. B vitamins play an essential role in brain function. Clinical observation strongly links folic acid to brain development. In combination with folic acid, vitamins B6 and vitamin B12 help manufacture and release chemicals in the brain known as neurotransmitters. The nervous system relies on these neurotransmitters to communicate messages within the brain, such as those that regulate mood, hunger, and sleep.

In addition, foods rich in antioxidant nutrients, such as vitamin A, C and vitamin E and beta-carotene, help protect brain cells from free-radical damage caused by environmental pollution. They are known as free radical scavengers and defense from free radicals is important to protecting the brain well into the golden years. Studies suggest that taking supplements of vitamins C and E can prevent the risk of Alzheimer’s disease and slow the progression of memory loss.

How brain foods help you think sound?

The brain utilizes 20 percent of the body’s carbohydrate supply. When the brain receives a steady supply of sugar for fuel, it chugs along smoothly at a steady pace. But when levels of sugar in the blood fluctuate, the brain doesn’t get its steady fuel supply. As a result, you may experience mental confusion, dizziness and if severe, convulsions and loss of consciousness. Foods with a low glycemic index provide brain friendly carbohydrates because they do not push the pancreas to secrete excess insulin, so the blood sugar tends to be steadier. Vegetables, legumes, whole grains, fruits and dairy products are foods with best brain sugars.

Sugars with high glycemic index can adversely affect the thinking and actions of some children. The sugars at fault include glucose, dextrose, and sucrose, and the highly refined, highly processed junk sugars found in candy, icings, syrups, packaged baked goods, and table sugar. The roller-coaster affects produced by these sugars affect moods and concentration in some children and adults, leading to sugar highs and sugar blues.

Proteins in the diet affect brain performance because they provide the amino acids from which neurotransmitters are made. The two important amino acids, tryptophan and tyrosine, are precursors of neurotransmitter. Fats are major components of the brain cell membrane and the myelin sheath around each nerve. So, our diet must include adequate amount of fat and the right kinds of fat can greatly affect brain development and performance.

Minerals are also critical to mental functioning and performance. Magnesium and manganese are needed for brain energy. Zinc is essential in protecting your mind and brain from the aging symptoms of forgetfulness. Sodium, potassium and calcium are important in the thinking process and facilitate the transmission of messages. Iron is also required to carry oxygen to the brain cells and aids in the formation of brain neurotransmitters, which affect attention and learning capacities.

Nuts

Nuts contain protein, high amounts of fiber, and they are rich in beneficial fats. They also contain plenty of vitamin B, E, and magnesium which are essential to cognitive function. They can clear up that brain fog and enable you to think clearer and are positive mood enhancers. Filberts, hazelnuts, cashews, and walnuts are great choices, with almonds being the king of nuts.

For those avoiding carbohydrates, macadamia nuts are much higher in fat than most nuts. Peanuts are not a good choice as many people are allergic to peanuts and have less healthy fat than many other types of nuts.

Seeds

Try seeds like sunflower seeds, sesame seeds, flax seeds, and tahini (a tangy, nutty sesame butter that tastes great in replacement of mayo and salad dressing). Seeds contain a lot of protein, beneficial fat, and vitamin E, as well as stress-fighting antioxidants and important brain-boosting minerals like magnesium.

They boost your mood and brainpower. Sunflower seeds contain tryptophan, an important amino acid that the brain converts to serotonin, which is a natural way to relieve mild depression and insomnia. Additionally, sunflower seeds are high in thiamine, an important B vitamin, which increases memory and cognitive function.

Eggs

Eggs are a precious source of high-quality proteins and rich in vitamins and minerals. The selenium in organic eggs is proven to help your mood. Nutrient called choline, found in eggs, can help boost the memory center in the brain. Choline increases the size of neurons, which helps them fire electrical signals more strongly and rebound faster between firings.

Two antioxidants found in egg yolk called lutein and zeaxanthin help prevent the risk of age-related cataracts and macular degeneration, two of the most prevalent age-related eye conditions.
For brain health, avocados are nearly as good as blueberries. Avocados contain mono-unsaturated fats, which contribute to healthy blood flow, the main requirement for a healthy brain. To include avocados to your diet, add 1/4 to 1/2 of an avocado to one meal daily as a side dish. Start each day with a mix of high-quality protein and beneficial fats to build the foundation for an energized day. Avocado with scrambled eggs are a great combination that serve the above purpose.

Berries

Berries contain antioxidants that help boost cognition, coordination, and memory. Blueberries are high in fiber and low on the glycemic index, thus they are safe for diabetics and they do not spike blood sugar. Blueberries are possibly the best brain food on earth as they boost the potency of neuron signals. They are also known as the “brain berry”, and are considered a super food when eaten in their natural form. They are also known to protect the brain from oxidative stress and may reduce the effects of age-related conditions such as Alzheimer’s disease and dementia.

Antioxidant-rich strawberries can prevent age-related neurological declines by improving brain cell abilities to send and receive the ’signaling’ molecules. The brain uses these signaling molecules to communicate. Blackberries are rich in nutrients called anthocyanins that help protect our brain from oxidation stress, which in turn fights degenerative brain diseases.

Pomegranate

Pomegranates contain blueberry-like levels of antioxidants, offering brain and memory protection. It carries a lot of vitamin C, A and E as well as fiber, iron and potassium and anti-inflammatory attributes help in strengthening the immune system.

Coffee

Coffee is good for your brain. You can safely enjoy 2 cups daily. Coffee is rich in antioxidants, amino acids, vitamins and minerals. Recent findings show it to be one of the best brain foods, reducing the risks of mental decline including diseases like dementia and Alzheimer’s.

Green tea

Green tea enhances memory and focus and fights mental fatigue. It contains catechines, which help you relax mentally and maintain your focus as well.

Green tea also helps maintain positive mood states and fights against many brain disorders. Polyphenols are powerful antioxidants found in green tea that can boost the availability of the important signaling brain substance dopamine in brain circuits.

Brown rice

Whole grains like brown rice are essential for maintaining concentration throughout the day and improving memory. That’s because they contain the perfect mix of carbohydrates and fiber to fuel your brain while keeping you full. The low-glycemic complex carbohydrate present in brown rice is excellent for people sensitive to gluten who still want to maintain cardiovascular health. Wholegrain breads and cereals are also rich in folate and Vitamin B6, an important brain vitamin.

Chocolate

Dark chocolate has brain boosting compounds; it’s rich in antioxidants and contains several natural stimulants which increase the production of endorphins while enhancing focus and concentration. It also releases dopamine, to enhance cognition and mood. It is also rich in fiber. It has high content of flavanol epicatechin that facilitate blood supply to the brain and enhance cognitive skills.

Milk chocolate jump starts impulse control and reaction time. It has also been known to improve visual and verbal memory.

Garlic

Garlic is one of the most potent nutritious foods. It is fabulous for reducing bad cholesterol and strengthening your cardiovascular system, and it exerts a protective antioxidant effect on the brain. It can potentially help against stroke, dementia and Alzheimer’s disease.

Green leafy vegetables

Spinach, kale, chard, romaine, arugula, lolla rossa and other green vegetables should be consumed on a daily basis. These vegetables are high in iron (slightly less “green” iron sources include beef, pork and lamb). Folate and vitamin B6, found in broccoli and kale, help convert tryptophan into serotonin, a brain chemical that boots mood alertness.

Tomatoes

Tomatoes are fantastic brain foods as there high content of lycopene make them an ideal source of unique of antioxidants. Lycopene is particularly good for brain – helps protect against free-radical damage to cells, which prevents brain from ageing and is believed to be a primary factor in cases of dementia, and particularly, Alzheimer’s disease.

Broccoli

Broccoli is a super food with high overall nutrient content. High levels of chemicals called homocysteines are linked with cognitive decline and Alzheimer’s disease.  In order to break themselves down, homocysteines require folate and B12 or B6, vitamins found in vegetables like broccoli. It is a great source of vitamin K, which enhances cognitive function and improves brainpower.

Wholegrain foods

Vitamins B6, B12 and folic acid are essential in protecting your memory. Wholegrain foods, such as whole grain breads and wheat germ are part of the best brain foods. Whole grain breads, cereals, barley, popcorn boost blood flow to the brain.

Wild salmon

Higher levels of omega-3 fatty acids in the blood go hand in hand with higher levels of serotonin, a mood-enhancing brain chemical. Thus, these fatty acids are responsible for improved cognition and alertness, reduced risk of degenerative mental disease (such as dementia), improved memory, improved mood, and reduced depression, anxiety and hyperactivity. Wild salmon is a premium source of these beneficial fats. Salmon is also rich in protein, calcium and vitamins A, D and B group.

Tuna

In addition to being another rich source of DHA (docosahexanoic acid), a type of omega-3s; tuna, particularly yellow fin, has the highest level of vitamin B6 of any food. Generally, the B vitamins are among the most important for balancing your mood. B6 in particular influences dopamine receptors, the “feel good” hormones along with serotonin.

Olive oil

A diet rich in healthy fats is essential to clear thinking, good memory, and a balanced mood. Olive oil is rich in antioxidants for healthy brain function. The extra virgin organic variety is best because the oil is produced naturally without chemical treatment. Raw unprocessed organic olive oil also contains fibers, and proteins.

Avoid processed fats as eating the wrong fat can literally alter your brain’s communication pathways.

Things that drain your brain

There are some foods that will cause a brain drain and work against your efforts.
It is advised to stay away from foods with high-fructose corn syrup; sugary drinks, colas, and juices; refined white sugars; items with trans fats and partially-hydrogenated oils, and other processed foods. Alcohol and nicotine are also known to cause reduced brain function.

A high carbohydrate meal

A high carbohydrate lunch makes you feel sleepy and sluggish. It is advised to opt for a light meal with some quality protein, such as a salad with grilled chicken breast or vegetables and hummus or wild American shrimp and avocado.

Corn syrup and sugar

They lead to health problems like diabetes and obesity, and are terrible for your brain. Don’t eat sugar except on special occasions or as an infrequent treat. Sugary fruit drinks, colas, and juices are among the worst offenders.

Nicotine

It constricts blood flow to the brain, so while it may soothe jittery nerves, smoking can actually reduce your brain function severely and the effects are cumulative.

Alcohol

Alcohol interferes with dopamine production. Moderate amounts of alcohol, particularly resveratrol-rich red wine, can help improve your health, but any alcoholic drink beyond a glass or two of wine daily is a recipe for reduced brain function and energy loss.

Due to the cruel realities of evolution weight loss requires the one thing we enjoy the least: PAIN

This is due to a fairly simple fact about your body. Your body wants to store fat, because through most of human history, food was scarce and in times of plenty it wants to store up for when supplies are short.

This is a process your body invented to keep you from starving to death, over centuries of living in a world that did not have McDonalds or that nice Chinese place the delivers. Any time you try to stop or undo that process, your brain will send you unpleasant reminders, because it thinks you’re setting youself up to starve to death.

To lose weight, you must endure pain. There is no shortcut.

When exercise to the point that your body will run out of the ready fuel in your system, it will reluctantly dip into its fat reserves and burn them. You will experience fatigue and our old friend pain when this happens. This is your body punishing you for using the fat it has stored up. It doesn’t want you to use it. Your body was keeping it for an emergency.  And here economists have been telling us Americans have trouble saving.

You can also cut back the amount of food coming into your system so that your body is forced to go through that same fat-burning process, but this time your body will punish you by making you feel hunger, sugar cravings or cravings for fattier foods that will let it replenish those fat reserves on your thighs and belly and everywhere else.

Any pill or cream that claims it can “burn fat” while your fat ass sits around watching Oprah, or exercise machine that claims to make exercise “easy” or “effortless” is a scam to steal your money.

There have also been numerous products put on the market intended to suppress hunger. But turning off one of the fundamental processes that keeps you alive is not an easy thing, and time and time again those pills turn out to be dangerous or even deadly. The popular diet drug Fen-Phen, pulled from the market due to potentially fatal side effects, only to be replaced by Ephedrine, which was also promptly banned in weight-loss products for being just as dangerous.

Now, most of the weight loss supplements you see at your grocer store now are just mild appetite suppressants, usually just packed full of caffeine or another stimulant, since the nervous, jittery, mildly sick feeling they induce does tend to kill your hunger.

The most recent and terrifying addition is Alli, the brand name of Orlistat, which lets you eat fat, but simply prevents it from being absorbed in the stomach. If this sounds like a perfect get-out-of-fat free card, keep in mind that (once again) you are short-circuiting one of the body’s natural processes. The result is that you will have uncontrollable greasy diarrhea, pooping out an orange substance like the stuff you see sitting on top of a pizza. The fat your stomach couldn’t absorb has to go somewhere.

If you are significantly overweight there is a fact that you will eventually have to come to terms with:  You eat too much.

Changing the types of food you eat and exercise are really important in assuring that your body is lean and healthy, but the truth is that no one has ever become seriously obese without overeating.   Sadly most diet plans overlook this.

The important question then is how do you eat less?   The answer is to gradually train your body to expect less food and adjust your habits to pick up less every time you eat.

The best way to do this is to eat smaller portions more often.   Many people eat 2 or 3 times a day.    Each time they eat they they are ravenous because they have not eaten for several hours.  This causes them to grab a large portion of food and consume it very quickly.    This is a very bad idea.

What you want to do is eat 6 times a day and cut your portions in half.  This will cause you to get in the habit of eating smaller portions without making you hungry.   You will also be less likely to overeat because you will be less hungry each time you sit down.

After a few weeks when you have become accustomed to eating smaller portions start cutting back to eating 5 times a day.  Stick with that for a few weeks.  Then go down to 4 and eventually to 3 times a day.     If you do this properly your body will not react to the reduction in food, you will not go into starvation mode and your weight will naturally drop to a more healthy level.
