Dr. Ahmet Özyiğit was born in 1981 in the Famagusta district of Cyprus. Ozgen and Dr. He is the youngest of Savaş Özyiğit's three children.

After completing his high school education at Türk Maarif College in 1998, he completed his undergraduate and graduate studies in economics in the American state of Kansas. Özyiğit, who later completed his doctorate education in the same field of science, published many articles in this field.

Özyiğit, who later became interested in medical science, studied medicine at the University of Nicosia Faculty of Medicine. In addition to this education, he received his master's degree in Clinical Embryology from the University of Leeds and postgraduate education in Endocrinology from the University of South Wales.

With an eclectic academic background, Dr. Özyiğit continues his clinical studies, especially on weight loss, metabolism and healthy aging. An active member of the American Academy of Anti-Aging Medicine, Dr. Özyiğit applies anti-aging, weight loss and brain function improving treatments to his patients.

Weight Loss

Weight Loss, Fat Burning and Metabolism Acceleration:

Obezite, çağımızın en kronikleşmiş ve pandemi seviyesine ulaşmış hastalıklarından bir tanesidir. 2023 itibarı ile, yetişkin dünya nüfusunun %13’ü obez, %39’u ise kilolu olarak sınıflandırılmıştır. Erkeklerde %11 olan obezite görülme oranı, kadınlarda %15 olarak gözlemlenir1.

Factors that determine susceptibility to weight gain or obesity can be called a person's eating and drinking habits, activity level, sleep quality, environmental factors and genetic factors.2. Although the person's metabolism or genetic predisposition are seen as factors, the biggest underlying problem is that the amount of energy consumed and the amount of energy spent are not equal.3.

In a comprehensive study lasting 20 years, covering the years 1986-2006, the relationship between the increase in consumption of certain foods and beverages and the rate of weight gain was observed. As a result of this comprehensive study, a significant weight gain was observed in women who increased their consumption of potatoes, potato chips, processed meats, red meat, fruit juice, sweetened drinks, butter and cereals, while women who increased their consumption of vegetables, fruits, whole grain foods, yoghurt and raw nuts. The weight gain rate was observed to be lower or negative. The table below shows the summary of the study.4:

People's sleep patterns and quality also appear as a factor that increases the tendency to obesity due to its direct effect on energy intake and expenditure. Although it increases 24-hour energy expenditure in people who sleep less than 7-8 hours a day, it will cause weight gain due to its effect on appetite hormones. People who do not sleep enough and stay up late at night are more likely to trigger weight gain, as their tendency to eat late and consume more unhealthy foods will increase, as well as hormonal changes.5.

Insufficient sleep and disruption of sleep patterns are factors that increase a person's risk of obesity and type 2 diabetes, especially thanks to their effects on ghrelin (hunger hormone) and leptin (satiety hormone).

Insufficient sleep will trigger more feelings of hunger and the need to eat due to the increase in cortisol level. However, it will increase the person's appetite due to the changes it will create in the levels of ghrelin, known as the hunger hormone, and leptin, known as the satiety hormone. We can see this relationship more clearly in the image below.6.

Low activity levels of people will also cause the amount of energy spent to be low and the amount of energy taken in not to be excreted from the body. Therefore, people with low activity levels will be more prone to weight gain and obesity. It has been determined by clinical studies that being inactive increases the risk of obesity, and even a daily light-paced walk reduces this risk. In the image below, the risk of sedentary activities, light walking and obesity are quantified.7:

Obesity is not just an appearance problem. Serious health problems are observed in people suffering from obesity. Cardiovascular diseases, type 2 diabetes, cancer, rheumatic diseases, liver and kidney diseases, sleep apnea and clinical depression are health problems directly associated with obesity.8. In this context, it has been reported that %8 of premature deaths observed worldwide are caused by obesity.1.

This being the case, preventing weight problems and preventing obesity has become an important public health problem. Since people being healthier and the incidence of chronic diseases decreasing will directly affect public health expenditures, effective public health policies are implemented to prevent weight problems, especially in developed countries.

Dr. As a result of both his clinical studies and research, Ahmet Özyiğit develops and offers treatments to his patients that will provide weight control and reduce the risk of obesity. In addition to these treatments, behavioral changes will also help the person age healthily and reduce the risks of chronic diseases.

In the first stage, a blood test is required to determine the person's metabolic activity and biochemical markers. In addition, determining the person's fat/muscle/water composition will also be effective in the path to be drawn.

Weight Loss Apps

Dr. Methods used by Ahmet Özyiğit for his weight problem:

Lifestyle changes

More movement, more fluid consumption, feeding time restriction and nutrition plan


Food supplements that support insulin resistance and cellular energy production.


Semaglutide etc. used for treatment. The names of the peptides are given below.


Semaglutide – Glukagon benzeri peptid (GLP1) analoğu olan bu peptid, tokluk hissi vermenin yanı sıra, gıdaların mideden bağırsağa geçişini yavaşlatmakta, ve tokluk hissiyatının uzun sürmesini sağlamaktadır. FDA onaylı olan bu peptid, 6 aylık kullanımda, ortalama olarak kişilerin vücut ağırlığının %15-20’sini vermesini sağlayabilmektedir.

How Does Semaglutide Treatment Help You Lose Weight?


MOTS-c – is a mitochondrial peptide of 16 amino acids. It has an important role in the body by regulating metabolic activity by translocating to the nucleus, especially when the body is under stress. There is a serious decrease in its level due to aging. It has been determined that MOTS-c peptide has important roles on a hormonal and cellular basis. Thanks to these roles, clinical studies have proven that they have positive effects against insulin resistance and type 2 diabetes, cardiovascular diseases, osteoporosis, obesity and dementia. Especially its benefits against aging9 and its positive effects against cardiovascular risk and inflammation.10 Thanks to this peptide, it is evolving into a very promising form of treatment.


Tesamorelin – Tesamorelin is an FDA-approved peptide used to eliminate central adiposity caused by drug use, especially in HIV+ patients.11. Studies conducted on non-HIV+ people have also found that it reduces fat in the abdominal area and provides slimming. In addition, some recent studies have found that tesamorelin not only has positive effects on fat burning but also on cognitive functions in older people. Although more studies are needed to measure the extent of such effects, it is very positive that it is promising in this direction.

CJC 1295

CJC 1295 – This peptide, which is 30 amino acids in size, aims to increase the body's own growth hormone production. It triggers fat burning by increasing both growth hormone and IGF-1 levels, and contributes to muscle formation by increasing protein synthesis. The increase in sleep quality and anti-aging properties are other features that make this peptide very attractive. This peptide, whose side effect profile was found to be quite innocent in clinical studies,12Since it has not yet received approval from the FDA, it can still be applied under the name of scientific study.
