Ghrelin is produced by ghrelin cells which are found in the stomach, lungs, pancreas and kidneys. It is a hormone that regulates hunger. When the stomach is empty, ghrelin is released. When food is eaten ghrelin secretion stops. Ghrelin increases appetite, increases food intake and promotes fat storage.
Ghrelin also promotes the release of growth hormone from the pituitary gland which breaks down fat tissue and helps building muscle tissue.
When people go on ‘yo yo’ diets – extreme calorie cutting diets, the weight they lose during dieting comes back on quick when the diet stops. One of the reasons why this happens is because the ghrelin levels are dramatically increased. The hormone levels stay like that for some time after the diet has stopped. The body reacts as if it went through starvation – which effectively it did, and to protect itself from future starvation it produces more ghrelin. In layman terms: you go on an extremely low calorie diet to lose weight. Your ghrelin levels increase so you feel more and more hungry. You are effectively starving on the diet to lose weight, and when you finally stop the diet, the body – to protect itself from further starvation – produces more ghrelin. Because you stopped the diet you go back eating normal and because you feel hungry you eat more and more – hence you put more weight back than what you’ve lost.
Ghrelin levels are primarily regulated by food intake. Levels of ghrelin increase when fasting (with increased hunger) and are lower in people with higher bodyweight than in lean people.
The different nutrients effect differently the release of ghrelin: protein and carbs slow down the production of ghrelin to a greater extent than fats – eating protein and carbs will make you feel fuller.

A calorie is NOT a calorie – Part 2
The thermic effect of food shows how much calories your body uses for digesting and processing the different macronutrients. The thermic effect of the different macronutrients is different. There is no exact numbers, researches show slightly different numbers, but the ballpark numbers are:
Protein is around 20-35%
Carbs 5-15%
Fats 0-5%
What does this mean? If you eat 200 kcal of protein, 40 – 70 kcal your body will use just to process and digest protein. So effectively you’ll only get about 65 – 80% of the protein you eat. For carbs it’s between 75 – 95% and for fats it’s 95 – 100% that the body will get.
It is very important if your goal is to build more muscle and you’re a hardgainer (ectomorph). Your body burns off an excessive amount of calories as heat because of your metabolism being inefficient. You need to make up for it in your nutrition. Since protein has up to 5x higher thermic effect than carbs or fats you should add more carbs or fats into your diet.
Body composition is another important factor here because the leaner you are, you show greater thermic effect.
The thermic effect of food is also higher post exercise. So if you’re a hardgainer, you should consider adding more calories (predominantly from carbs and fats) into your nutrition outside of the post workout window.
A calorie is NOT a calorie – Part 1
I would like to talk about the calories here, because a lot of people think that all calories are equal.
For example let’s look at the difference between glucose and fructose. They’re both simple sugars and they both have the same amount of calories, but glucose can be metabolised by all the body’s tissues, while fructose can only be metabolised by the liver.
Fructose can be found in fruits and vegetables, but it is also manufactured in a lab.
Glucose is also called grape sugar or blood sugar and can be found in all major carbohydrates like starch or table sugar. They are both good sources of energy but excess glucose can be fatal to diabetic patients and excess fructose can lead to insulin resistance or non alcoholic liver disease.
Most fat gained from excessive glucose is subcutaneous (under the skin) and is not linked to diabetes or heart disease.
Fructose leads to higher ghrelin levels than glucose. Why it is important you may ask? Because ghrelin is the hormone that’s responsible for your hunger. Glucose decreases food intake.
High fructose sweeteners, soft drinks and corn syrup cause a rise in obesity. High fructose diet (too much sweeteners) promotes insulin intolerance which will cause abdominal fat gain and increased triglyceride.
So a calorie is NOT a calorie here, there’s a difference.
Happy Valentine’s Day!
February already?
Time really flies here in Egypt. I think it’s because I’m used to having 4 seasons and now it’s only 1. It’s like time stands still, you don’t even realise the weeks passing by, and then all of a sudden, out of the blue BANG! It’s February!
Work has been a bit busy therefore I didn’t have much time to go out, but a few weeks ago I visited old Cairo which was a lovely experience. I will upload all the photos soon, hopefully over the weekend, once I’ve edited them. I will try and do a bit more tourist stuff here, because so far I’ve only been to the gym (which is also work) 🙂
Enjoy your week! Come back for updates!
Dear Diary…
So another year has passed and life has thrown a few curveballs at me in 2014. It was a very eventful year and I have no regrets. Life is an experience and you know what? I rather have an eventful experience, than a boring one 🙂
It all started in January when I decided to move on. I thought I had to get out of the UK for some time. You know, when you just get fed up with things, with the people around you, with your job and you just need a break? This is how I felt. I got very depressed and I knew I had to snap out of that feeling. I decided to return to Istanbul/Turkey for a month, to train and enjoy myself. I had a great time there! My friends were welcoming and my training went very well.
The plan was to go to Dubai from Istanbul, but somehow I got derailed. A friend of mine invited me to Cairo and because I have never been to Egypt before I decided to visit. I arrived end of March and got introduced to Gold’s Gym Academy the following day. After that things just speeded up. First I was offered a freelance position at the Academy to lecture there, and then I was interviewed for a position for Gold’s Gym Egypt that I got and started 1st May. This job is great, I enjoy the company and the people I have to work with. Well, most of them. I have a great boss who helps me a lot when I need help. He doesn’t like it when I call him ‘boss’ but effectively he is 🙂
I say currently my boss because things keep changing everywhere. I guess it’s the ups and downs of life.
I’m lucky enough to meet a wide range of people. I believe that everyone comes into our lives for a reason. Some people are meant to stay, others are meant to teach us something. And eventually they all make us happy: by either coming into our lives or by leaving 🙂
I’ve made some friends, I have a lot of followers here in Egypt and it’s a great feeling to know that I inspire so many people.
I don’t know what the situation is with the guys here but I have a lot of attention from guys in their 20s. Apparently they like older women – and they are very persistent. If I was only looking for a toyboy just to spend my time with someone it would be probably great (Oh and that’s all about it what you can expect because of their religion lol) It’s all bonkers here 🙂 so might as well just try and enjoy until I’m here. I have made some friends though: some guys from the gym, some of the trainers and the Max Muscle guys, they are a treat really! I can’t express how lovely and helpful they are!
Trying to plan my year in regards to competitions but I gotta admit it’s a bit scary because the quality of the food here is very poor. Last year it was a proper struggle to diet down. I’m trying to look for ‘organic’ food but I don’t think they know the concept here although they use the word. Just stay connected to see the updates!
Dear Diary, 2014 was a long and eventful year. But everything happens for a reason and I believe that I am where I am supposed to be. New Year’s resolution? I don’t believe in that. I believe if you want to start something you should not wait until new year’s, or Monday or the next day. So my only promise to myself is to treat myself better, to put myself first in EVERY situation. If you’re not careful, people abuse your friendliness and kind nature easily. There is a saying that is very true: givers need to set limits because takers rarely do. That’s my motto for 2015.
About fat loss and supplements
Let me spare some thoughts on weight loss and supplements. I’ve heard this several times: I want to lose weight,I can’t take supplements. It depends on what supplements we are talking about. Whey protein? Well I believe that you can get away with not taking whey protein. If your main goal is to lose bodyfat then I would say try and stick to real, clean food. Why? Because the main aim of any whey protein is to get digested and absorbed quickly and easily. You see where I’m going with this? If it is easily digested then the body don’t need to put effort into digesting it = it won’t use much energy (calories) to digest it. However when you eat clean food – ie chicken, tuna, turkey etc – your body will burn more energy by just simply digesting the food. So I would say if you need to lose a lot of weight you can stay away from whey protein. Where will you get your protein from you may ask? First of all from your food – that should be the main source. Clean food: eggs, chicken, tuna, fish, red meat, turkey etc The second most important source should be amino acids.
Amino acids are the building blocks for protein. There are 20-22 standard amino acids, 8-10 of which are considered essential. That means you need to supplement these because your body cannot synthesize them. There are around 14 non-essential amino acids and a lot of other metabolites that are derived from these 8 essential amino acids.
Amino acids can be used for energy. When they’re used for energy, they cannot be used for building tissue and performing their other metabolic functions. Ladies, you don’t need to put on too much muscle, but you still need to understand that the more muscles you have the higher your metabolism is, which means you burn more energy even when resting. So some muscles will not only look good on you but will increase your metabolism which also means you will need to eat more, too. Quite handy, isn’t it?
During starvation the body releases amino acids from muscle issue to be used for energy. This also occurs during exercise and when the body runs out of carbs fuel from the diet or from glycogen stored in the muscles and liver. Unless proteins are present in the diet aminos are released, even if the body has fat for fuel.
BCAAs (branched chain amino acids) are used by muscles to supply a limited amount of energy during strenuous exercise. These are isoleucine, valine and leucine. Leucine is depleted the most frequently. Trained person’s muscles use up some amounts of leucine even at rest. Complete proteins are proteins that contain the essential amino acids in amounts that are sufficient for maintenance. Incomplete proteins are usually deficient in one or more of the essential amino acids.
So my advice: regardless of your aim in training (losing weight or putting on muscle) supplementing with amino acids and BCAAs is essential.
About the different diets: Keto, Atkins and Paleo
Women in the locker room constantly keep asking me for diet tips, telling me what they do and what they heard they should do. They’re doing different diets, mostly fad diets. I believe that once you change your lifestyle and eating habits for the better and you start seeing results, you will never look back. However unfortunately many women seem to think that they can have a ‘quick fix’ to lose some weight by a crash diet and then go back to ‘normal’ which unfortunately causes all the weight and fat to come back, too.
In the following few days I will sum up some of the most popular diets, which could be a basis of how you change your eating habits.
The Ketogenic (keto) diet:
This diet is high in fats, low in carbs and moderate in protein. This diet causes the body’s metabolism to shift from glucose to fat utilisation. Ketones are produced by the liver. This diet can improve several health conditions, like Parkinson’s, Alzheimer’s, epilepsy and even cancer because healthy cells can use fats for energy, however cancer cells cannot so they starve to death. When you eat high carb foods your body produces glucose and insulin. Insulin is responsible to down regulate the glucose levels in the blood stream. Insulin is also responsible for storing fat in the body. If you produce too much insulin, you put on weight – simple.
There are different types of keto diets:
- standard keto diet: you eat 20-50 gr of net carbs / day This is the same as the induction phase of Atkins diet.
- Targeted keto diet: you eat carbs 30-60 mins before exercise. This is an old approach however you can give it a go because not everyone is the same and what works for one might not work for others and vice versa. But just for the records: you don’t need carbs before your workout.
- Targeted keto diet alternative with no extra carbs: the idea of this approach is that your body may not need extra carbs before exercise to perform well. Again, you need to try this approach to see how you feel on it.
- Cycling keto diet: what many bodybuilders use. You alternate keto dieting with high carb days – effectively you do carb loading. Use about 50 gr of carbs on the keto days and 300-600 gr on the high days – obviously depending on your needs and bodytypes. This is only for professional and high performing athletes, not for people wanting to lose a bit of weight.
The Atkins diet:
The idea is that when you cut back on carbs your body turns to your fat stores for fuel. The result is that you burn body fat and your body releases a by-product called ketones that your body will use for energy.
This diet starts off as a keto diet in the induction phase. You drastically reduce your carb intake down to 20 gr, you cut out pasta, bread, potato or any starchy carb and dairy, and you only eat certain vegetables (fibres). No alcohol, no caffeine, no nuts, seeds or legumes.
After this comes the ‘ongoing weight loss’ phase when you add back slowly more vegetables, nuts, seeds, legumes, berries and other fruits and eventually wholegrains.
Then comes the phase when you might be able to add more carbs and foods back into your diet depending on your body’s needs.
Because of the food limitations in this diet, especially at the beginning, you will need to supplement vitamins especially potassium, magnesium and calcium.
The paleo diet:
This diet is based on our ancestors’ diets. Back in the days humans were hunters/gatherers. Then became farmers. So instead of loading up on meat, vegetables and seasonable fruits, we eat bread, pasta and grains. Back in the days grains were not part of our diet. Grains are composed of carbs and turned into glucose to be used for energy. Any glucose that isn’t used for energy will turn to fat. Our modern diet is full with refined food, trans fat and sugar which leads to diseases like: obesity, cancer, heart disease, diabetes, Parkinson’s, Alzheimer’s etc. There is a big difference between the fat content and quality of our modern grain fed animals vs grass fed wild animals. Wild meat is remarkably lean, and has relatively low amounts of saturated fats, while supplying significant amount of beneficial Omega-3 fats.
The foods that are OK to eat on a paleo diet are:
- Grass fed lean meat, fowl (chicken, turkey, hen, duck, anything with wings), wild fish (not farmed fish), eggs, vegetables (not deep fried), oils (olive, coconut, avocado), fruits, nuts and seeds, tubers (sweet potato, yams)
If you stick to the foods you are allowed to eat on this diet you should not get fat because these foods are very nutrient densed foods so it’s almost impossible to overeat.
The foods that you need to avoid on a paleo diet are:
- Dairy, grains, processed food & sugar, legumes, starches, alcohol
The health benefits of paleo:
- more efficient workouts,
- stable blood sugar,
- burn off stored fat,
- reduce allergies,
- balanced energy throughout the day,
- anti-inflammatory,
- better skin and teeth,
- improved sleep patterns
What kind of a nation….?
What kind of a nation is that who screw over each other? Their own and the foreigner?
I know there are bad people everywhere in the world. It doesn’t have to be a specific country. However I have travelled the world and I’ve never met so self centered, two faced people, or at least not so many in one place!
At work some people want to control everything – and usually the most stupidest ones! Obviously the ones who cannot even see through what it would take.
Competitive athletes screwing each other over money for gear – as if the contest prep would not be expensive enough for everyone.
People offer you their help so that they can kick you even more when you’re down and you really need that help.
Very very bad experiences in the last few weeks and I don’t feel that happy anymore! If this is what’s going on here then it’s easy to tell why this country is where it is at.
Single minded, self centered, ignorant people. Not everyone but after a point you just don’t know who you can trust. I always thought I’m a friendly, open, happy and very helpful person but I think I need an attitude adjustment. Quick.
There are always exceptions to the rules – and those people know who they are. As for the others, my message is: what goes around comes around! If I’m lucky enough karma will let me see it…
How to burn stubborn bodyfat?
- visceral – surrounding the organs,
- subcutaneous – beneath the skin, 80% of bodyfat.
- white is the fat that makes up 90% of your bodyfat. It has a very low metabolic rate, so it doesn’t burn calories therefore it is more like a storage unit for calories.
- brown fat can burn calories because of its rich blood supply. Unfortunately we have very little of them.
- beige fat is in between white and brown in terms of calorie burning capacity.
- ELEL allows a very low calorie or low carb diet because you reduce your resistance training and cardio during the week therefore you don’t need high calories but you don’t burn that many calories either because of the lack of exercise. This doesn’t mean you have to sit in front of the TV all day. You should still go for a walk and do low impact cardio on a daily basis. The key word here is ‘low impact’.
- In the EMEM approach you increase your calorie intake but you also increase the intensity of your workouts. This approach is better and more healthy because high intensity workouts and more food will also increase your metabolism and your fat burning.
