Lack of Sleep Causes Sweet-Tooth and Overeating!

 


You heard that right - not getting enough quality sleep is directly linked to craving sweets, weight gain, and difficulty losing weight!

Sleep: Your Body’s Best Friend

Sleep is important for just about all the systems in your body, and lack of sleep reduces cognitive function including reduced reaction time, impaired decision making and memory.  Sleep is also essential for the repair and recovery of your body.

Even if you think you get enough shut-eye you may still be suffering from the symptoms of sleep deprivation.   Unfortunately, just a little sleep deprivation can have a significant effect on weight gain.

How Lack of Sleep Causes Weight Gain

Lack of sleep increases the levels of a stress hormone called cortisol, and cortisol increases appetite significantly.  Sleep deprivation also saps willpower and decision-making ability so not only are you hungrier – you are more likely to make poor food choices.     Sleep deprivation is a stressor and when you feel stressed you tend to choose high carb foods which boost serotonin.

At the same time, the body’s ability to handle carbs properly is reduced.    Your cells become less sensitive to the effects of insulin called insulin insensitivity which is what type 2 diabetes is all about.   If lack of sleep is a chronic condition you quite literally can make yourself gain weight and become diabetic!

In addition, when you are tired, a hormone called Ghrelin is boosted while Leptin levels drop.   This is quite literally a double whammy because Ghrelin increases hunger and Leptin tells you when you are full and satisfied.   Lack of sleep makes you hungrier, but you do not feel satisfied when you do eat so you eat more!

In fact, studies have shown increased calorie intake of over 300 extra calories per day in sleep-deprived people.

Sleep is as important as exercise and diet so make it a priority and check out this previous blogpost on how to improve your sleep: http://workoutanytime.blogspot.com/2020/04/sleep-in-time-of-coronavirus.html

Nutrition Strategies for Fall Allergies

 


It's time for fall allergy symptoms to start kicking in.   Treating allergies with nutrition and nutritional supplements can be very helpful.   

Allergy medication most commonly comes in the form of antihistamines, and there are some problems with long-term use of these medications.   It is now known that prolonged use of antihistamines decreases levels of acetylcholine in the brain which is a key neurotransmitter involved in memory and other important functions.   In fact, long-term use of antihistamines increases the risk of senility, dementia and Alzheimer’s Disease in older adults.

What are Allergies Anyway?

Allergies are abnormal immune reactions to specific agents (proteins) known as antigens/allergens, which include many substances such as foods, drugs, pollens, dust mites, animal danders, feathers, along with many others. 

Since there are multiple pro-inflammatory chemicals produced in your body in allergies it is rare to obtain adequate control with single products/medications.  The most potent chemical mediators in allergies and asthma are leukotrienes.  Some leukotrienes are one thousand times more potent than histamine as stimulators of bronchial constriction and allergy. 

Interestingly, many medications that reduce one inflammatory pathway actually boost leukotrienes. For example, Aspirin and other NSAIDs (Non-Steroidal Anti-Inflammatory Drugs like Ibuprofen) result in the production of excessive levels of leukotrienes in sensitive individuals although they decrease prostaglandins associated with inflammation and thereby relieve pain.  

Asthma is linked to allergies and can be a severe and life threatening condition.   Do NOT try to self-treat Asthma – see a physician!

Strategies for Allergies

Try to avoid allergens by using air filters, regularly cleaning all surfaces and vacuuming and keeping your air-conditioning system on while regularly changing filters to filter out as many allergens as possible.   Remember your car cabin filter as well and take showers and wash clothes after being outside for long periods of time.

Change your diet to reduce inflammation.   Increase your intake of low glycemic, organic fruits and vegetables such as berries, broccoli, brussel sprouts, etc.   These plant foods contain polyphenols which are potent anti-oxidants and help to reduce inflammation and allergies without side effects.

Increase your intake of Omega 3 Fatty Acids from cold water fish such as Alaskan Wild Salmon and/or take an Omega 3 Supplement.   Omega 3 fatty acids will always reduce inflammation if taken in sufficient dosages so this should be a primary strategy for allergy sufferers because they produce many side benefits.   The only exception is people taking any type of blood thinner medication.   In this case the combination can be dangerous!

Nutritional Supplements for Allergies

There are several highly effective nutritional supplements for allergies including some key herbs.

Local Raw Honey – it MUST be local and must be raw because it will contain small amounts of local pollen and works by getting the body used to pollen much like an allergy shot. A tablespoon a day is as much as you need.   Many people swear by this simple and safe remedy!

Stinging Nettle Extract – this herb has a long history of effective use for allergies and freeze-dried preparations seem to work the best and are best taken BEFORE allergy season even begins to put a damper on symptoms before they start – this is true of all nutritional approaches to allergy by the way!

Euphrasia Officianalis – aka “Eyebright” is an herb whose name says it all – it is highly effective for eye allergy symptoms.

Quercetin – is a flavonoid contained in high amounts in capers, apples, peppers, red wine, dark cherries and berries, tomatoes, cruciferous vegetables such as broccoli, cabbage and sprouts, and raw red onions.   To treat allergies taking supplemental quercetin is the way to go and the best Quercetin Supplements are Quercetin Phytosome supplements. An excellent product is Mercola Quercetin and Pterostilbene which can be purchased on Amazon.  Two 250mg capsules a day is a good dose. Quercetin is also proven to decrease your chance of contracting a viral illness like the cold or flu by 9 times!

Boswellia Extract – Boswellia aka Frankincense (yes the herb mentioned in the bible!) can be highly effective for allergies and other forms of inflammation including arthritis because it blocks the formation of leukotrienes!   To get the benefits you must take 5-loxin which is a specific extract.   Note that in some individuals 5-loxin can cause or exacerbate heart burn so it is not for everyone, but when it works it can be highly effective!

Butterbur Extract – this plant extract can be highly effective for inhibiting leukotrienes and allergy symptoms or side effects.   You need to take a standardized extract with standardized levels of Petasin and Isopetasin) and free of Pyrrolizidine Alkaloids aka PA.  High quality brands include Life Extension, Swanson, and Enzymatic Therapy to name a few.   This product can also help many migraine sufferers and is a well-researched, proven treatment.

NAC – N-Acetyl Cysteine - helps thin mucus naturally and boost levels of the body’s most important antioxidant Glutathione – every allergy sufferer should be taking 600 – 1,200mg per day!

 

You will also find combination of these ingredients in particular products, and it is worth experimenting a bit because if you find the right product or combination of natural products you can find relief without sedation and without the side effects associated with antihistamines and more potent

Isometric Exercise is the Most Effective Exercise for Blood Pressure Lowering

 

You heard that right – isometric exercise is superior to all other forms of exercise for lowering blood pressure!   This includes all forms of cardiovascular exercise and all other forms of strength training exercise.  Many studies have shown this including a large meta-analysis which showed that isometric exercise is as effective as  blood pressure drugs for lowering blood pressure. 

Isometric exercise compresses the blood vessels (particularly the veins which old over 60% of your blood). If you think of your blood vessels like a garden hose, think of what happens when you pull on both ends of a rubber garden hose - the inside diameter shrinks - and this means increase pressure is required to get the same amount of blood through the center. However if you push both ends of the hose together towards the center (like isometric exercise) the diameter actually increases and you need less pressure to move the same amount of blood!

In addition, isometric exercise has side benefits - not side effects like drugs! For example - isometrics improve joint health, improve muscle imbalances, improve performance, and are very safe and time efficient!

A simple routine done 3 times per week can provide big benefits. Just do the following three exercises 3 - 5 times per week holding each one for 30 -90 seconds:

Wall Sit

Plank

Side Plank

Eating Sugar at Breakfast Can Sabotage Weight Loss!


Many people notice that eating breakfast makes them hungrier throughout the day, and this is probably NOT their imagination!   In this case the culprit is likely what they eat.  Specifically, refined carbohydrates, including sugar, can drive hunger particularly if they are consumed with no fat or protein.

A recent study tested this hypothesis with 16 healthy young women between the ages of 18 and 30 who had a stable body weight for the last 3 months.   Anyone with diabetes or on medications that affect appetite was excluded along with people who were allergic to any part of the meals given as part of the study.

Participants fasted for a minimum of 8 hours prior to the study.   In the morning participants came to the laboratory and were given a standardized test meal consisting of passion fruit juice, one cup of coffee, French bread and 5 grams of margarine.   The two drinks had no sugar added and the participants were instructed to sweeten to their preferred taste.

The sugar container given to the participants was weighed both before and after its use by each person to know the amount of sugar each person added to their drinks.   After completing the entire meal participants did not eat or drink anything (except water) until lunchtime.

Lunch was served 3 hours after breakfast and consisted of pasta with tomato sauce, and participants were instructed to eat until they felt satisfied. 

Study Results

The participants were divided into two groups based on the amount of sugar they elected to add to their breakfast.   The high sugar group added about 25 grams of sugar to breakfast while the low sugar group only added 14 grams of sugar.

Both groups were evaluated for their perception of hunger and satiety.   The high sugar group had significantly higher levels of hunger during the three hours after breakfast AND consumed significantly more pasta at lunch!

Take Home Message

Avoid high sugar breakfasts such as standard breakfast cereal, fruit juices (eat fruit don’t drink it!) and consume 15 – 20 grams of protein and a small amount of fat.   Also try to add higher fiber carb choices like berries instead of banana, adding spinach to an omelet, etc.  Examples include an omelet with spinach with berries or a shake with protein, greens, and a small amount of MCT oil for fat.
