CLIENT IMPROVES KIDNEY FUNCTION WITH NUTRITIONAL THERAPY

The 63 yr old female client had a history of mildly reduced kidney function, but not chronic kidney disease.

When we began working together on 24 May 2026, her most recent eGFR available was 63.48 mL/min/1.73 m² (26 June 2026). Her previous results had shown a gradual decline from 95.99 in January 2023 to 84.53 in December 2024, followed by the more pronounced reduction to 63.48.

eGFR is an estimate rather than a direct measurement of filtration and can be influenced by factors including creatinine, muscle mass, dietary intake and biological variation. Dehydration was ruled out as a result of analysing the clients past blood results, the blood key markers which may rise as a result of frank dehydration, were not showing. The program was not intended specifically to target the kidney, improvements occurred as a result of the overall support.

The latest result, 81 mL/min/1.73 m² on 3 August 2026, represents an increase of approximately 28% from the June result (see image). This is an encouraging change, although a single improvement does not by itself establish a sustained change in underlying kidney function; trends over time are more informative.

Guidelines recommends assessing potential sources of error and variability when interpreting changes in eGFR, such as using the same labs which we did.

CLIENT WEIGHT LOSS, AND IMPROVES OSTEOARTHRITIS & KIDNEY FUNCTION WITH NUTRITIONAL THERAPY + PERSONAL TRAINING

63 year old female feedback "My Osteoarthritis has improved a lot. I was in a fair-to-severe amount of pain everyday. I can walk upstairs more easily. Now I would say, my knee is uncomfortable than painful. It still feels more delicate, stiff at times and I have mild pain especially if i stand or walk. I was getting to the end of my tether, and becoming unable to cope with the pain level some days. Now its a lot more manageable, and so quality of life has improved."

HIGHER CHOLESTEROL & IRON, AND LOWER GLUCOSE, INCREASES THE ODDS OF REACHING 100 YEARS OF AGE

A large Swedish cohort study tracking thousands of participants over more than three decades, suggested that those who became centenarians (100 yrs), tended to have higher total cholesterol and iron levels, and lower glucose levels, compared with peers who died younger, highlighting the importance of diet in longevity.

Source:https://pmc.ncbi.nlm.nih.gov/articles/PMC10828184/pdf/11357_2023_Article_936.pdf

- Cholesterol levels 240–270 mg/dL = 6.2–7.0 mmol/L
- Iron levels >13 umol/L
- Glucose levels 83 mg/dL = 4.6 mmol/L

However, the study is observational in nature and therefore cannot establish a cause-and-effect relationship. Other lines of research suggests that having lower levels of total cholesterol may reduce the risks of cardiovascular events and dementia.

In my opinion, a risk assessment depends not just on cholesterol numbers, but many other factors, such as a person’s lifestyle, medications, diet, physical activity, smoking & alcohol frequency, history of cardiovascular disease or dementia, kidney function, blood pressure status, ‘good’ HDL cholesterol levels, and genetic variants. Its more nuanced that just cholesterol numbers.

THE EFFECTS OF EXERCISE ON DEPRESSION

Major Systematic review & network meta-analysis of randomised controlled trials involving 218 studies with a total 14 170 participants, suggests thats tue more intense the exercise, the more potent the antidepressant effects, even a walk has a clinically important effects. Jogging, yoga, and strength training more found to be more effective than other exercises

CLINICAL TRIAL SUGGESTS A LOW-CARB KETOGENIC DIET BEATS A MEDITERRANEAN & LOW-FAT DIETS FOR METABOLIC IMPROVEMENTS IN OBESE PERSONS

Context matters in nutrition and health! In sharp contrast to my previous post highlighting a clinical trial identifying genetic responses to saturated fat and cholesterol levels with a low carb diet, a newly published randomised clinical trials suggests that despite consuming 3x more saturated fat, adherence to a low-carb ketogenic diet provided the greatest health benefits for people with obesity.

The clinical trial involved forty two participants (9 women; 5 men p/grp) who had obesity, pre-diabetes and fatty liver disease. The researchers randomly assigned them to one of three diet groups: a ketogenic diet, a Mediterranean diet or a low-fat, plant-forward diet over 6 months.

Regular blood testing revealed that the ketogenic diet group had the largest increase in glucagon, a hormone that promotes fat loss in the liver. That group also experienced the greatest reduction in blood insulin levels, which also reduces fat content in the liver, compared with the other two groups. The most surprising finding was that participants in the ketogenic diet group didn't experience an increase in blood fat or cholesterol levels despite consuming the most fat.

Ketogenic diets are not for everyone, it has it's pros and cons, and only on very specific situations have I used them depending on individual case history and suitability. They are not easy to sustain, and very easy to do it wrongly or 'fall off the wagon'. It's also challenging from a social aspect. Supervision is recommended, and that is something I can advise on, track, and oversee. I did my degree research project on this so I have a lot of knowledge on the subject.

LOW CARB DIETS RAISES 'BAD' LDL CHOLESTEROL IN GENETICALLY PREDISPOSED

Although this research is not news to me as it has been known for a long time, a new clinical trial by the American Society for Nutrition, (again) suggests that low-carb diet may raise their low-density lipoprotein (LDL) 'bad' cholesterol much more sharply in people who are genetically predisposed to high cholesterol, particularly when they consume lots of saturated fat. The findings could help explain why people following seemingly similar diets can have dramatically different results:

Source: https://www.eurekalert.org/news-releases/1136476

The results of the study known as the DIETFITS Trial, indicates that saturated fat, which can make up a larger share of some low-carb diets, may interact with a person's genetic makeup to raise LDL cholesterol, a suspected (but debatable) contributor to heart disease risk. This genetic influence could help explain why two people following similar diets can have very different cholesterol responses.

Earlier research has found that healthy low carbohydrate diets can help some people lose weight, improve blood sugar control and other cardio-metabolic biomarkers. Their impact on LDL cholesterol, however, has been inconsistent.

In contrast, other lines of research suggests that those on a lower carb or ketogenic diets, despite showing a tendency to increase total and LDL cholesterol, also increase their 'good' HDL cholesterol which is generally linked to a reduced risk of cardiovascular disease, although not all research agrees.

Additionally those following a low-carb diet for a considerable amount of time, tends to exhibit a particular phenotype whereby their LDL particle number and size appears to (potentially) be less atherogenic.

I recently shared a post on my page specially about this phenomenon here https://bit.ly/4hRCns4 but whether this phenotype translates to a reduced risk of cardiovascular disease is uncertain and currently being researched.

If you are concerned about low carb diets, have a family history of high cholesterol, and want to have an alternative view on diets, lifestyle, cardiovascular risks and support, get in touch to arrange a blood test and consultation with me.
