About Caffeine

Caffeine is one of the most effective exercise supplements available. It is also very cheap and relatively safe to use.

Studies have shown that caffeine can benefit endurance performance, high-intensity exercise and power sports. However, it seems to benefit trained athletes the most.

Caffeine is rapidly absorbed into the bloodstream and blood levels peak after 90-100 minutes. Caffeine levels remain high for 3-4 hours, then they drop.

Caffeine affects the nervous system to improve focus and energy while reducing tiredness.

The recommended dose varies by body weight, but is typically about 200–400 mg, taken 30–60 minutes before a workout.

Caffeine is a common ingredients in weight loss supplements. Early research has shown that taking caffeine before exercise increases the release of stored fat by 30% .

Another study found that caffeine supplements significantly increased the release of stored fat before and at the end of a workout.

Caffeine can also increase the amount of fat you burn during exercise. It increases heat production and epinephrine, which helps burn additional calories and fat.

Caffeine can affect cells throughout the body, including muscle cells and the brain. Its effects include:

The nervous system: Caffeine activates areas of the brain and nervous system to improve focus and energy, while reducing tiredness

Hormones: ephineprine(adrenaline) is the hormone responsible for the “fight or flight” response, which can increase performan

Fat burning: Caffeine can increase the body’s ability to burn fat via lipolysis, or the breakdown of fat in fat cells

Endorphins: can increase feelings of wellness, and give you the exercise “high” that people often experience after working out

Muscles: Caffeine may impact the motor cortex, which is a part of the brain that signals muscle activation

Body temperature: Caffeine has been shown to increase thermogenesis, or heat production, which helps you burn more calories

Glycogen: Caffeine may also spare muscle carb stores, primarily due to increased fat burning. This can enhance endurance performance

Caffeine eventually gets broken down in the liver.

The side effects of caffeine:

  • Increased heart rate
  • Anxiety
  • Dizziness
  • Insomnia or sleep disruption
  • Irritability
  • Tremors
  • Stomach discomfort
  • High doses of 600 mg have been shown to increase tremors and restlessness, especially for people who are not used to caffeine.

People who are prone to anxiety may also want to avoid high doses.

Additionally, caffeine is not recommended for people who take certain medications, as well as those with a heart condition or high blood pressure.

Timing may also matter, as late-night or evening caffeine can disrupt sleep. Try to avoid caffeine intake after 4 or 5 pm.

How to boost the immune system?

The immune system is an interactive network of organs, cells and proteins that protect the body from viruses and bacteria or any foreign substances. The immune system works to neutralize and remove pathogens like bacteria, viruses, parasites or fungi that enter the body, recognize and neutralize harmful substances from the environment, and fight against the body’s own cells that have changes due to an illness.

The cells of the immune system originate in the bone marrow, then migrate to guard the peripheral tissues, circulating in the blood and in the specialized system of vessels called the lymphatic system.

When our immune system is working properly, we don’t even notice it. It’s when the performance of our immune system is compromised that we face illness. Underactivity of the immune system results in severe infections and tumors of immunodeficiency, while overactivity results in allergic and autoimmune diseases.

Give your immune system a boost with these tips:

  • Supplement with echinacea: Research shows that one of the most significant echinacea benefits is its effects when used on recurring infections.
  • Supplement with probiotics: Probiotics are good bacteria that help you digest nutrients that boost the detoxification of your colon and support your immune system.
  • Eat more ginger: It’s believed that ginger helps to break down the accumulation of toxins in our organs due to its warming effects. It’s also known to cleanse the lymphatic system,our network of tissues and organs that help rid the body of toxins, waste and other unwanted materials.
  • Eat more berries: berries are full with antioxidants, that are excellent for promoting healthy immune response.
  • Get more rest: restful sleep is absolutely essential for health and recovery. When you sleep certain protective cytokines in your body increase in levels, and inflammatory cells decline, which means that less sleep could result in a deprived immune system.
  • Have some garlic: it is great to avoid any cold, flu or other viruses. If you don’t like the taste of it, try capsules.
  • Aerobic exercise boosts immune system: people who are fit and active are less likely to suffer from illnesses and the symptoms are less severe.

My transformation

Here is my own transformation: 2007 – 2016.
Yes, 9 years is a long time, however it’s a journey. During these years I tried a lot of things: different foods, supplements, training methods, and put in a lot of time researching the best ways to stay or become lean and put on muscle, and throughout this journey I have been reshaping my physique.
I’ve been training since I was 14. Working hard in the gym was not new to me. However I only realized the importance of nutrition around 2009 and this is when my real transformation started.
During the years I’ve researched different training methods and different approaches to nutrition and diet. I do differentiate between athletes and ‘everyday people’ and I understand the difference in their level of commitment and how manageable it is for them to train and eat right.
I provide nutrition and training plans for all levels, whether it be weight loss, fitness or contest preparation. I am available for personal training at Physique Warehouse Gym in West Molesey (Surrey), or at Elmbridge Xcel Leisure Centre in Walton on Thames. I’m also available for online coaching.

Tips on how to avoid putting on fat during Xmas

Xmas is coming fast and when the family and friends gather together it’s always accompanied by food and drinks. It’s a celebration, isn’t it? More often than not the food is not a healthy one and you might start panicking what to do to not to put on weight this season. Here are a few tips that might help you:

Stay active! Just because it’s Xmas it doesn’t mean everything stops – apart from your metabolism, that might stop if you are not active and overeat. Some of the gyms are open during xmas time, and even if yours is not, you can always go for a walk – slow or fast – after your meal or in the evening.

Get more Vitamin D3: If there’s no direct sunshine where you live – especially here in the UK, get some Vitamin D3 supplements. Vitamin D3 contributes to the normal function of the immune system and healthy inflammatory response and to the maintenance of normal muscle function.

Eat more protein and veggies: meat and vegetables/fibre help keep blood glucose and insulin levels down, help you burn fat and keep you from getting sick. Not to mention that they will make you feel full, too so you might eat less carbs.

Lower your sugar and carb intake: with the plates full with processed food and sugars/simple carbs, the single most effective thing you can do is watch your portion size of these foods. Don’t have a whole slice of cake, try only a bite. Don’t have a whole plate of pasta or other high carb food, try just a spoonful. If you watch your portion sizes you can probably try most of the xmas foods without being sick afterwards or feeling guilty for eating too much of them.

For athletes: 9 science based ways to lose weight

Recently I’ve come across an article that talks about 9 science-based ways for athletes to lose weight. When you think about it, it’s always more difficult to lose weight when you’re always training, always eating clean. Humans need a certain amount of bodyfat to maintain basic functions. Too much bodyfat – however – can negatively affect an athlete’s performance. So what can athletes do to ‘step up’ their weight loss to be in prime condition and shape?

  1.  The first point this article suggests is to lose weight off season. We are talking about b athletes in general. It does make sense to try and lose the excess bodyfat offseason because it’s very difficult to reach peak fitness while dieting. When you’re not eating enough calories, your athletic perfomance will suffer. Losing weight offseason will give you more time to lose the excess bodyfat as well, so that you don’t have to rush the fat loss and can stick to the healthy pace of 0.5 kg / week – minimising the muscle loss.
  2. Avoid crash diets. I think we don’t really need to prove this point, athletes know that they need a certain amount of calories to be able to perform at the training sessions. Also drastically reducing your caloric intake will affect your metabolism and hormonal balance. Athletes should only cut their calories by no more than 300-500 kcal a day.

  3. Eat less sugar and more fibre. Low carb diets are proven to be the best for fat loss. However restricting the carb intake too much will affect your athletic performance. To reduce the carb intake cut out added sugars, and avoid cane juice, dextrin, maltodextrin, barley malt, caramel, fruit juice concentrate, fruit juice crystals and any type of syrup. Instead increase your intake of vegetables high in fibre.

  4. Increase your protein intake. Protein promotes fat loss in several ways: high protein diets increase feelings of fullness and the number of calories burnt through digestion. High protein diets also prevent muscle loss during periods of weight loss. Therefore athletes restricting their calories to lose weight should eat between 1.7 – 2.8 gr protein / kg of bodyweight / day.

  5. Spread protein intake throughout the day. 20-30 gr protein per meal is sufficient to stimulate muscles to produce protein for the following 2-3 hrs. Eating a snack containing 40 gr protein before bed can increase muscle protein synthesis during night. This may help prevent some of the muscle loss expected during sleep.

  6. Refuel well after training. Eating the right foods after competing or training is very important for the athletes, especially when trying to lose bodyfat. Proper refuelling is very important especially on days when you have more than 1 events with less than 8 hours recovery time. Carbs with protein can speed up recovery time and promote protein production in your muscles.

  7. Strength training can also help holding on to the muscle when trying to lose bodyfat. Research shows that both protein intake and strength training stimulate muscle protein synthesis and combining the two can produce an even better effect.

  8. After your diet, increase your calories gradually. It may be tempting to start eating normally again after you’ve reached your desired body fat percentage, but that would lead you to gain bodyfat back. Gradually increasing your caloric intake can help restore your hormone levels and metabolism better, minimizing the weight gain.

  9. Here are some other ways you can achieve weight loss:

    • measuring your portions and keeping track of what you eat is scientifically proven to help you get better results.
    • drinking before consuming a meal can help you consume 22% less calories
    • eat slowly, aim to take at least 20 mins for a meal
    • avoid alcohol
    • get enough sleep, not enough sleep can increase hunger and appetite by 24%. Not getting enough sleep will also affect your athletic performance.
    • reduce your stress. Having high stress levels will increase cortisol levels which promotes food cravings and drive to eat. Mental and physical stress can also prevent proper recovery.

About Creatine

Creatine is a protein that is naturally made of 3 amino acids: arginine, glycine and methionine. It can also be found in meat and fish, and can be taken as a supplement.

Creatine combines with phosphorus to form phosphocreatine (PC) in the muscle cells. This fuels your muscles during high intensity training, such as sprinting or lifting weights. Creatine raises PC levels around 2%, which means you can sustain all out effort for longer and recover faster between sets.

Protein promotes muscle hypertrophy and protein manufacture. Lot of studies show that short-term creatine supplementation increases body mass. Studies found that creatine supplements improved strength, the number of repetitions performed to fatigue, and the ability to perform repeated sprints.

How does creatine work?

The gains observed are partly due to the increase of cell volume and partly muscle synthesis.

Creatine cause water to move across cell membranes. When muscle cell creatine concentration goes up, water is drawn into the cell an effect that boosts the thickness of muscle fibres by about 15%. The water content of muscle fibres stretches the cell’s outer sheaths.

In aerobic sports there is less evidence for creatine use. This is probably due to the fact the PC energy system is less important during endurance training.

Who should use it?

If you train with weights, or do any sports that includes high-intensity movements (sprints, jumps or throws: rugby, football, hockey, gymnastics, tennis etc), creatine supplements may help increase your performance, strength and muscle mass.

Taking carbs with creatine can be beneficial, as carb intake increases insulin which helps creatine uptake by the muscle cells.

Creatine monohydrate is the most widely available form of creatine. It comprises a molecule of creatine with a molecule of water attached to it. It requires a loading phase. One way to do it is to take about 20-25 gr / day in 4-5 doses for 5 days. After the loading phase the dosage is 2 gr / day.

The side effects of Creatine:

The main side effect is weight gain. This is partly due to the extra water in the muscle cells, and party to increased muscle tissue. It could be disadvantageous in sports where there’s a critical ratio of bodyweight and speed (like running), or in sports where there are weight categories.

About L-Carnitine

L-Carnitine is one of the naturally occurring amino acids. It is often used as a weight loss supplement. It transports the fatty acids into the cells’ mitochondria where it gets burnt off to use as energy. Your body can produce L-Carnitine from the amino acids lysine and methionine. You can also obtain small amount of L-Carnitine from your diet by eating meat or fish.

L-Carnitine L-Tartrate is the most common form of L-Carnitine that is used in most sport supplements, because of its fast absorption and it may help with muscle soreness and recovery.

In human studies, taking acetyl-L-carnitine daily helped reverse the decline in brain function associated with Alzheimer’s and other brain diseases.

Some studies have demonstrated a potential benefit for reducing blood pressure and the inflammatory process associated with heart disease.

L-carnitine may benefit:

Recovery:It may improve exercise recovery.

Muscle oxygen supply: It may increase oxygen supply to the muscles

Stamina: It may increase blood flow and nitric oxide production, helping delay the “burn” and reduce fatigue

Muscle soreness: It may reduce muscle soreness after exercise

Red blood cell production: It may increase the production of red blood cells, which transport oxygen throughout your body and muscles.

L-carnitine has also been shown to reduce symptoms of type 2 diabetes and its associated risk factors.

The main foods high in L-Carnitine are:

  • – beef
  • – pork
  • – fish
  • – chicken
  • – milk

 L-Carnitine has a greater absorption rate from food than from supplements.

Doses of 2 grams or less per day seem to be well tolerated and safe for most people. Some people have reported nausea or other digestive side effects, but no serious issues have been found.

About ephedrine

The main ingredient in fat burners or thermogenics is ephedrine, a synthetic version of a chinese herb ephedra, or also known as ma huang.

Ephedrine is a drug, rather than a nutrition supplement. It is also used in low concentrations in flu and cold remedies (pseudoephedrine).

Ephedrine is chemically similar to amphetamines, which act on the brain and the central nervous system.

There is some evidence that ephedrine helps fat loss: partly due to an increase in thermogenesis, partly because it suppresses your appetite and partly because it makes you more active.

When taken as an ECA stack (ephedrine – caffeine – aspirin) ephedrine has a greater effect in terms of weight loss and thermogenesis. However the fat burning effect of ephedrine seems to decrease over time.

Ephedrine is judged to be safe in doses between 18-25 mg, that’s the amount that’s used in cold remedies. Doses more than 32 mg a day may triple your risk of bleeding in the brain. Prolonged use and higher doses combined with heavy exercise increase your risk of side effects, like increased heart rate, increased blood pressure, palpitations, anxiety, nervousness, insomnia, headaches, nausea, vomiting and dizziness.

Ephedrine is addictive, and people can develop a tolerance to it, which means you will need to take more and more to get the same effects.

About caffeine

Caffeine was once classed as a banned substance but was removed from the World Anti-Doping Agency prohibited list in 2004. Caffeine is a stimulant and has pharmacological action on the body therefore is classed as a drug rather than a nutrient.
Caffeine is found in everyday drinks and foods, such as coffee, black tea, green tea, cola, herbs such as guarana, both dark and white chocolate and it is added to a number of energy drinks and sports drinks and gels. 
Caffeine acts on the central nervous system, increasing alertness and concentration. These effects reduce the perception of fatigue and allow exercise to be maintained at a higher intensity for a longer period. 
Large number of studies show that caffeine intake can enhance performance at doses of 1-3mg/kg. There appears to be little increase in performance above 3mg/kg. for a 70kg person, this would be 210mg = 2 cups of coffee or 2 cans of caffeinated energy drinks.
Performance benefits occur soon after consumption, so caffeine may be consumed just before exercise, spread throughout exercise or late in exercise as fatigue is beginning to occur.
Although caffeine is a diuretic, a daily intake of less than 300mg caffeine results in no larger urine output than water. Taking caffeine regularly builds up your caffeine tolerance so you experience smaller diuretic effects.
Caffeine consumption likely causes a short-term spike in blood pressure after consumption, with the spike being more pronounced in those who don’t normally ingest caffeine and in those with hypertension. However, the evidence concerning the long-term effects of caffeine and caffeinated beverages on blood pressure is mixed.
Caffeine may raise eye pressure, but only in those who have pre-existing eye conditions like glaucoma.
Coffee contains oily substances called diterpenes, and the 2 main types are cafestol and kahweol that increase the cholesterol levels. Coffee filters trap most of the cafestol and kahweol though, so instant or filter coffee don’t contain much of these, only boiled coffee. 

About BCAAs

BCAAs are the most popular amino acid supplements. They contain:

  • Valine
  • Leucine
  • Isoleucine

 These 3 amino acids make up to one third of muscle in the body. The body breaks down muscle to get energy, especially during strenuous exercise, to get these amino acids.

 BCAAs are converted into 2 other amino acids:

  • glutamine and
  • alanine,

which are released in large quantities during aerobic exercise. They can also be used directly for fuel, especially when muscle glycogen is depleted.

 Foods high in BCAAs:

  • Meats: red meat is the highest in BCAAs. Other meats (poultry etc) are high in BCAAs, too because they’re primarily protein. Choose lean cuts, chicken breast without the skin etc
  • Eggs: they are packed with nutrition and BCAAs, and easy to add to your diet.
  • Dairy products are high in BCAAs: low fat cheese, milk, cottage cheese, yogurt, frozen yogurt. Additional dairy options could be: cheese, cream and butter.
  • Liquid and powder protein: very popular source, easy to prepare, drink and digest. If you mix your whey protein with milk, you boost the BCAA content of your shake.

Taking BCAA supplements before and during exercise can reduce muscle breakdown. They may also help preserve muscle in athletes on a low carb diet. It will probably not boost your endurance, however taking 6 – 15 gr of BCAAs daily may help improve your recovery.

 Side effects: BCAAs are relatively safe because they are normally found in protein in the diet.
