Caffeine crash

Caffeine high and crash

Many people who drink caffeine beverages experience tiredness, caffeine crashes and hangover symptoms. How do they prevent this from happening?

Caffeine crash

A caffeine crash usually occurs a few hours after a person has consumed a moderate to high dose of caffeine, when they were previously in a tired state. There is a reason for this!

Symptoms of a Caffeine Crash

  • Extreme tiredness
  • Inability to concentrate
  • Irritability
  • Dozing off

What are the reasons for a caffeine crash?

In simple terms:

Caffeine stops the “you are getting tired and need to take a nap, or go to sleep” chemical (called Adenosine) from attaching to the brain.

As the caffeine starts to wear off as caffeine gets metabolized, the “go to sleep” chemicals will now be flooding the brain! The brain is now telling you to “pass out urgently” (CRASH!), rather than being nudged to do so.

Adenosine promotes sleep and suppresses arousal. When awake the levels of adenosine in the brain rise each hour .

When a person is already feeling tired, they have increased levels of adenosine in their brains. If they consume caffeine, the caffeine molecule blocks the adenosine from attaching to its receptors in the brain. However, while the caffeine is keeping a person alert and energetic adenosine is continuing to build up in the person’s brain.

After a few hours, as caffeine is metabolized, its effects begin to wear off. The built up adenosine then floods its receptors which signals the body that it is time for sleep, but at a level much more intense than normal.

This is the feeling of the caffeine crash.

How to Avoid a Caffeine Crash

  • Get enough sleep
  • Reduce caffeine beverages
  • Eat a healthy breakfast

The first step in avoiding a caffeine crash is to get adequate rest.

Starting out the day with normal adenosine levels helps prevent a crash.

Spread out your caffeine consumption throughout your workday.

Instead of having two coffees back to back in the morning, have one in the morning and another at lunchtime. Better still, cut out the coffee and energy drinks, and replace it with green tea , or you cannot stomach green tea, normal tea!

Keep your caffeine dose within reason. A single dose of more than 200 mg of caffeine at one time can lead to a caffeine crash. You can trick your mind by replacing half your instant coffee dosage with a caffeine free portion (1/2 spoon caffeinated & 1/2 spoon of caffeine-free of the same brand – for example).

Don’t consume caffeine on an empty stomach. Food provides real energy for your body and caffeine only provides a temporary sense of energy. Without real calories, the body will quickly feel fatigued and tired once the caffeine wears off. Eat a healthy breakfast along with your dose of caffeine.

Caffeine Hangover

What goes up must come down. When a person comes down from having too much caffeine, it can feel like a hangover.

Caffeine puts you on a chemically induced “high”.

Drastic changes in daily caffeine consumption can trigger a caffeine headache which is similar to the way someone feels when they are hungover from alcohol.

Because of the high levels of caffeine, the neurotransmitter adenosine was able to build up in the brain. Once the caffeine is metabolized, the brain is flooded with adenosine which causes feelings of extreme tiredness and lethargy.

Too much caffeine can also cause nausea and vomiting which is another may it can mimic the consumption of too much alcohol.

How to Avoid a Caffeine Hangover

Get plenty of sleep, eat a healthy diet, and then use caffeine to give you that extra edge of alertness and productivity that will help you do your job or your studies without overdoing it.

Caffeine is not a replacement for sleep.

Fast tan

To tan, you will need to spend some time in the sun.

Tan faster than ever before

Get as much safe sun exposure in a week – without burning. Slow and easy tanning over a period of time is the best way to tan.

Boost your tan – fastest tanning

Boost your tan by increasing melanin by using MT2.

Melanotan II was first synthesized at the University of Arizona. Researchers there knew that one of the best defenses against skin cancer was melanin activated in the skin, a tan.

They hypothesized that an effective way to reduce skin cancer rates in people would be to induce the body’s natural pigmentary system to produce a protective tan prior to UV exposure.

The body’s naturally occurring hormone α-MSH causes melanogenesis, a process by which the skin’s pigment cells (melanocytes) produce the skin’s pigment (melanin).

They tested to see if administering this endogenous hormone to the body directly could be an effective method to cause sunless tanning. What they found was that while it appeared to work, natural α-MSH had too short a half life in the body to be practical as a therapeutic drug. So they decided to find a more potent and stable alternative, one that would be more practical and so Melanotan 2 was born.

Foods that enhances tan

Carrots. When carrots are consumed regularly (and in moderation), the skin adapts a more natural and healthy-looking hue.

The following food will enhance your skin tone, when eaten regularly and in moderation:

Tomatoes, sweet potatoes, cantaloupe and apricots. Like carrots, these carotenoid rich fruits and veggies improve your skin’s color while providing other health benefits.

Spinach and kale. These dark, leafy greens should definitely be a staple in your diet, as well as broccoli, as they are the secret to glowing skin.

Olive Oil. Although olive oil doesn’t contain any carotenoids, antioxidants and omega-3s, it will give your skin a moisture boost for a healthier appearance.

How Much Exercise to Lose Weight?

To lose weight and to keep it off requires a lifestyle change.

You need to eat healthier and increase your cardio or activity.

Eating healthier means reducing fatty foods and cutting out sweet drinks. This means stop eating takeouts and start eating healthy home-prepared meals – this means steamed vegetables and low-fat meats and fish.

When someone over-exercises, they might over-eat as well.

The trick here is to train your brain and body to either eat smaller portion of high-protein food, and having meal replacements.

So how much time is required to lose weight?

Science shows that 150 to 250 minutes a week is required to start burning off the fat.

This means 35 minutes a day, or if training daily is not possible, getting most of your exercise on a weekend, with a few extra minutes during the week, will work, as long as your moderate top vigorous exercise is 250 minutes a week.

You can also increase your intensity (such as running instead of walking), which will increase the burning rate and reduce the amount of time to lose weight.

How Much Exercise Per Day to Lose 1Kg?

If you’re curious about how much exercise it would take to burn one pound of body fat. You can use an activity calculator to help provide the answer. You need to burn about 3500 calories to lose 1/2Kg of weight.

 These activities would help a 70kg-pound person burn roughly enough calories to lose 1/2Kg:

5 hours of running or roughly 40 minutes per day
14 hours of walking or 2 hours per day
5 hours of vigorous swimming or about 40 minutes per day
6.5 hours of biking (12-13 miles per hour) or just under an hour each day
7 hours of intense aerobics class or 7 one-hour classes per week

That is a lot!

So the best way to reduce this effort, is to reduce your food intake.
The inconvenience of feeling peckish or hungry, is easier than exercising what seems like an eternity.

The most important thing is weighing yourself weekly, not daily.

If you have not lost anything, reduce your food by 10% and increase your exercise by 10%.

Check your results and adjust until your weight goal is being met. You should aim for a maximum of 1Kg a week.

What should my heart rate be?

Your resting heart rate, or RHR, is a great way to determine your health.

When reting, your heart should be within the range shown, or you may suffer short as well as long term effects.

Your RHR is how fast your heart beats when you are relaxed. Check the resting heart rate chart below to see how you compare to your age group.

  Your Resting Heart Rate is how many times your heart beats per minute while you are resting.

    A normal resting heart rate is between 60 bpm and 100 bpm.

  Having a high resting heart rate increases the risk of serious diseases and speeds up the aging process.

  You can lower your resting heart rate with exercise, relaxation, and eating beans.

How to Measure Resting Heart Rate

To take your pulse, place your index finger and your middle finger on one of your pulse points and count the number of heartbeats for 15 seconds, then multiply by four.

Wait until you are relaxed. If you’ve just finished exercising or you’re stressed, your RHR will be elevated.

When Should You Check Your Resting Heart Rate?

The best time to check your resting heart rate is when you wake up in the morning before you get out of bed. Check your RHR at the same time and rested state every day to get an accurate reading.

You can also measure your heart rate (HR) right after exercise to track your maximum heart rate.

What Are the Best Places to Check Pulse?

The best places to check your heart rate are your wrist, the side of your neck, the inside of your elbow, and the top of your foot.

Heart Rate Monitors

You can track your heart rate with a wrist monitor (such as a smart watch that monitors heart rates)

Heart rate monitors make it easier to track your heart rate consistently and learn which activities raise or lower it the most.

Beet juice for stamina

Beet root juice – super food for stamina

“Super food” lists don’t include beet root juice, but they should.

Beet juice may boost stamina to help you exercise for longer, it improves blood flow and lowers blood pressure.

Beet root is rich in natural chemicals called nitrates. Through a chain reaction, your body changes nitrates into nitric oxide, which helps with blood-flow and blood pressure.

In some studies, drinking about 2 cups of beet juice daily or taking nitrate capsules lowered blood pressure in healthy adults.

Beet juice may also help your stamina when you exercise. In one study, people who drank beet juice for 6 days had better stamina during intense exercise.

Beet Juice Nutrition

One cup of raw beets has 58 calories and 13 grams of carbohydrates.

A cup of beet juice is usually around 100 calories and 25 grams of carbohydrates, because of the way it is processed.

Beets are good sources of folate, potassium, vitamin C, fiber, and antioxidants, as well as nitrates.

Other good food sources of nitrates include spinach, radishes, lettuce, celery, and Chinese cabbage.

Eating cooked beets won’t give you the same quantity of nitrates, because cooking hampers some of the nitrates, but is still good for your health.

If you start drinking beet juice, you should know that it may make your urine and stools look reddish.

Delicious beetroot juice (Juicer recipe)

1 medium beet (rinsed, lightly peeled and quartered)
1 (or 2) medium apple (peeled, cored and quartered)
1 Tbsp size piece of fresh ginger (skin removed)
3 whole carrots (rinsed and peeled)
Unfiltered apple juice or cold water (optional)
Juice from 2 lemons (variant on flavour)
Ice (recommended)

Optional ingredients you may try for variety and boost to your vitamins and minerals intake

Handful of kale leaves or spinach 
4 stalks of celery (reduce carrots to 2)
Place all ingredients (except the ice and lemon juice) in a juicer, adding 1/8 to 1/4 cup of apple juice or cold water if needed to get it moving and to thin the drink, according to taste.

Add the lemon juice (you may try the recipe without the lemon juice for a smoother taste)

Add ice for a better tasting drink.

Will keep in a fridge for 24 hours.

Build a better body faster at home – no gym

To get a better body at home still takes work!

For the next 30 days, do 100 pushups – every day.

You can split it up during the day, watching TV, when you wake up or before bedtime, as long as you do 100 pushups that day!

No cheating, do 100 reps, do not skip any reps, and do not carry anything forward.

In the standard pushup, the following muscles are targeted:

chest muscles, or pectorals
shoulders, or deltoids
back of your arms, or triceps
the “wing” muscles directly under your armpit, called the serratus anterior

For the next 30 days, do 100 weight-free squats every day.

This will give you great legs and a great butt

High protein diet

Healthy foods that are actually bad

Don’t fall for labels without reading between the lines.

Protein breakfast cereals

“Protein breakfast cereals” are expensive, have little protein and contains sugar. Stick with standard oats for a healthy alternative, and decide whether to add a scoop of whey powder, or to have eggs for protein.

Bran flakes and shredded bran

“Bran flakes or shredded bran” – check the label for added sugar and the suggested serving size. You could be consuming 3 or more teaspoons of sugar per realistic serving size, and if you consume it with milk, it will be even more sugars!

Unhealthy spreads

Breakfast treats like “Chocolate Nut” spreads “Can be part of a balanced breakfast”! FALSE! These things are just melted chocolate bars spread on toast.

Instant Soups

Healthy soups – a suggested serving is usually less than what is included in a container. These soups have so much sodium in them, that they even beat a whole bag of potato chips. It is recommended to limit sodium to less than 2,300 mg per day.

The recommended sodium intake is less than 2,300 mg per day.

Instant “cup” soups contain 650mg or more per sachet. Some have more than 1000mg per sachet.

Instant “cup” soups contain 650mg of sodium, and sometimes more. Some cup soups have more than 1000mg per serving.

Energy bars

These are just glorified candy bars.

350 / 400 calories per serving is a whole lot of calories in a compact format!

Fruit bars

Would you like 6 1/2 Orios in a single serving? One “healthy” fruit bar can contains as much sugar as 6 ½ Orios!

Hydrating sports drinks

“Electrolytes, sodium, potassium” and high amounts of sugar! These drinks are not needed if you train moderately for 30 minutes, or even an hour.

There are sugar-free alternatives, which is a better option. If you suffer from muscle cramps, supplementation may be an option. Read the label of the supplements and cut the sugars.

The electrolytes in human bodies include:

  • sodium
  • potassium
  • calcium
  • bicarbonate
  • magnesium
  • chloride
  • phosphate

Low fat milk

90 calories per glass of skimmed milk. Skim milk is water with lactose sugar. Full fat milk has 149 calories per glass as it contains fat, so even though it may seem that skim milk is better, it is higher on the glycemic index (GI) scale than whole milk by a solid five points, which could explain why it’s associated with a greater risk of diabetes risk!

GI is a measurement of how fast a carbohydrate breaks down into glucose in the body and therefore how quickly your blood sugar rises or falls.

Whole milk is actually healthier than skim milk.

It is still best to cut the milk and replace it with water when possible.

Bran muffins

Bran muffins are just normal muffins that include additional bran. The sugar, fat and flour is the same as regular muffins.

Dried fruit

Dehydrated fruits sound great, they taste great, but they pack many more calories per gram than the original fruit.

Eat fresh fruits and skip the dried fruit.

Fruit Juice

Fruit juice is easy to consume, and it contains a lot of sugar – without the benefit of fibre.

Middle age men can increase free testosterone levels by taking DHEA suppliments

DHEA has been tested and has shown to benefit 40 year old + individuals doing HIIT (high-intensity interval training) .

Warning: DHEA is for middle age men with low testosterone levels only, do not buy DHEA on the black market. Consult a doctor who will determine if supplementation is required.

Symptoms of low testosterone include:

  1. Low sex drive
  2. Difficulty with erection
  3. Low semen volume
  4. Hair loss (body and facial hair)
  5. Fatigue
  6. Loss of muscle mass
  7. Increased body fat
  8. Decreased bone mass
  9. Mood changes
  10. Affected memory
  11. Smaller testicle size

Free testosterone of DHEA-supplemented middle-aged men remained unaffected.

This after it was found that middle-aged participants exhibited significantly lower free testosterone and greater luteinizing hormone (LH) levels than the young control group after HIIT without supplementation.

If you are older than 40, it is working checking with your doctor, do blood tests to check your testosterone levels and see what your doctor recommends.

More information may be found below regarding the research.

With advancing age, plasma testosterone levels decline, with free testosterone levels declining more significantly than total testosterone. This fall is thought to underlie the development of physical and mental weakness that occurs with advancing age. In addition, vigorous exercise can also lower total and free testosterone levels with the decline greatest in physically untrained men. The purpose of the study was to evaluate the effect of oral DHEA supplementation, a testosterone precursor, on free testosterone in sedentary middle-aged men during recovery from a high-intensity interval training (HIIT) bout of exercise. A randomized, double-blind, placebo-controlled crossover study was conducted for 8 middle-aged participants (aged 49.3 ± 2.4 years) and an additional 8 young control participants (aged 21.4 ± 0.3 years). Each participant received DHEA (50 mg) and placebo on separate occasions one night (12 h) before a 5-session, 2-min cycling exercise (100% VO₂max). While no significant age difference in total testosterone was found, middle-aged participants exhibited significantly lower free testosterone and greater luteinizing hormone (LH) levels than the young control group. Oral DHEA supplementation increased circulating DHEA-S and free testosterone levels well above baseline in the middle-aged group, with no significant effect on total testosterone levels. Total testosterone and DHEA-S dropped significantly until 24 h after HIIT for both age groups, while free testosterone of DHEA-supplemented middle-aged men remained unaffected. These results demonstrate acute oral DHEA supplementation can elevate free testosterone levels in middle-aged men and prevent it from declining during HIIT. Therefore, DHEA supplementation may have significant benefits related to HIIT adaptation.

I do cardio every day but am not losing weight!

There are many reasons why you are not losing weight but… the main reason is that you are not creating a caloric deficit. In other words, you are still eating more food than you are exercising it off.

If you are frustrated, then the solution is simple, start approaching your weight loss scientifically.

Keep track of what you eat! You are eating too much!

Start keeping track of what you eat, including weekends. That extra ice cream, the cappuccino or coffee with a sugar adds up. If in doubt, leave it out.

Eat slowly when you do eat, and only eat enough – until you no longer feel “hungry”.

Snack on fresh, healthy fruits such as apples and pears. Stay away from the cup cakes, chocolates and even “health bars”.

Small portions of low fat, low salt beef, ostrich or chicken biltong is a good snack to supplement your fruit.

A high protein supplement or meal replacement is also good as long it is replacing an entire meal, and not adding or supplementing to an existing meal.

You are doing to much cardio!

Doing cardio is essential for losing fat, however, 90 minutes of cardio daily is going to reduce muscle mass.

Muscles burn fat during the day, and by reducing muscle mass, you are creating reducing active muscle mass and still keeping inactive fat mass.

Your body also believes it is being started, increasing your appetite to start storing “emergency reserves” – fat!

You are doing too little cardio!

Doing too little cardio, not only in time, but also in effort.

Stay within your fat- burn zone and only train enough time to burn the number of calories you need to create a caloric deficit.

Hit the weight or super circuit at your gym and you can burn 200 calories in about 20 minutes. Not only that, but you will be defining your muscles and strengthening your bones.

You are not lifting weights

Start weight lifting and increase your strength, whether you are a man or woman. Lifting weights tones your body and increases fat burning. Get rid of the flab and look great.

You are not taking time out

Taking time out is very important for recovery. If you do not recover fully, you will tired, unmotivated, you will be pushing yourself less, and ultimately you will not be losing any weight or gaining muscle.

When you exercise, or when you are under a lot of stress, your body starts to produce an excessive amount of cortisol, a stress hormone. Cortisol is both normal and important when working out, it’s involved in processes that give your muscles the energy needed to get moving.

However, when your body is exposed to cortisol for longer periods of time, it starts to cause negative effects, like stubborn fat in areas you don’t want.

If you are addicted to gym, set a day aside for stretching and light cardio such as walking on a treadmill without breaking a sweat. However, taking a full day or two of rest is best.

Where does fat go?

Fat is not expelled from the body as “fat”.

You actually breath and sweat your fat out.

When your body needs more energy than what is available from carbohydrates and protein, fat is converted into energy.

This process produces oxygen and water when it breaks down the fat.

The oxygen is breathed out through your lungs as Carbon Dioxide, and the water is sweated out.

By not eating (intermittent fasting, such as not eating until midday), HGH (Human growth hormone) is released in your body, which breaks fat down.

You also need to move your body to start to break the fat down.

Intermittent fasting, low calorie diets, lots of sweating and huffing & puffing will break down the most fat.
