Keto Nutrition in Weight Optimisation
Optimal weight is not a number — it is a metabolic state. Keto does not “slim” people through magic. It creates the metabolic conditions in which the body returns to its natural weight and maintains it effortlessly.
Why We Lose Weight on Keto — The Real Mechanisms
- Visceral fat burning — fat around the organs (the dangerous kind) is prioritised in ketosis. Not subcutaneous fat — visceral fat, which is metabolically active and pro-inflammatory.
- Natural appetite suppression — ketones reduce ghrelin (the hunger hormone) and maintain satiety for hours. No need to count calories — the body self-regulates.
- Leptin normalisation — low insulin allows leptin to function normally, sending the signal “I have sufficient energy, burn the fat.”
- Thermic effect of protein — digesting protein burns more energy than digesting carbohydrates. Keto slightly raises basal metabolic rate.
- Muscle mass preservation — unlike classic low-calorie diets, keto with adequate essential amino acids preserves and builds muscle mass while burning fat.
Strict SKD (below 20g carbs) + daily 16:8 fasting + moderate (not extreme) caloric deficit + essential amino acids to preserve muscle mass. Weekly measurement of body composition, not weight.
If weight loss stops: check Dr. Boz Ratio, eliminate processed “keto” products, add a 24h fast per week, check fat calories (high caloric density).
Keto and the Nervous System
The brain and nervous system are the primary beneficiaries of ketosis — though this is perhaps the least known and most important aspect of ketogenic nutrition.
Brain insulin resistance. As the body becomes systemically insulin resistant, the brain follows the same pattern. Brain cells can no longer use glucose efficiently — and begin to “starve” even when glucose is available. Ketones bypass this problem entirely.
- Alzheimer’s — the Alzheimer’s brain has lost the ability to use glucose. Ketones provide alternative energy to the remaining functional brain cells. Some researchers call Alzheimer’s “type 3 diabetes.”
- Parkinson’s — ketones reduce mitochondrial oxidative stress in dopaminergic neurons — precisely the ones affected. Animal studies and a few human pilot studies show slowing of progression.
- Multiple sclerosis — reduction of systemic inflammation and neuroprotective effects have shown promising results in pilot studies.
- Epilepsy — the best-documented therapeutic application. The classic ketogenic diet reduces seizure frequency by 50–90% in children with drug-resistant epilepsy. Used clinically since 1920.
- Depression and anxiety — through neurotransmitter stabilisation (GABA potentiated, inflammation reduced, glycaemic variability eliminated), keto shows documented antidepressant effects.
Keto and the Emotional Implications
The mind-body connection is more direct in keto than in any other nutritional approach. The metabolic changes produced by ketosis have profound and relatively rapid effects on emotional state.
Serotonin, Cortisol, and Carbohydrates
Serotonin (the happiness hormone) and cortisol (the stress hormone) are in inverse tandem: when one is high, the other is low. Chronic stress → elevated cortisol → low serotonin → cravings for carbohydrates.
Carbohydrates temporarily raise serotonin — this is the biological basis of “comfort eating.” The problem: the effect is short-lived and followed by an even greater crash. The cycle repeats. Keto stabilises serotonin by eliminating glycaemic variability — not through artificial spikes.
Research shows a direct link between diet quality and mental health (Dr. Georgia Ede, psychiatrist specialising in nutrition). Keto addresses depression through: glucose stabilisation, reduction of brain inflammation, neurotransmitter optimisation, and increasing BDNF (brain-derived neurotrophic factor) through exercise and ketosis.
Keto Nutrition and the Hormonal System
Hormones control almost everything in the body: metabolism, weight, mood, fertility, sleep quality, energy, cognition. Keto is one of the most powerful hormonal interventions available without medication.
| Hormone | Keto effect | Practical impact |
|---|---|---|
| Insulin | Major decrease | Fat burning activated, insulin resistance reversed |
| Glucagon | Increase | Fat mobilisation from stores, ketone production |
| Leptin | Normalisation | Satiety restored, appetite regulation |
| Ghrelin (hunger) | Reduction | Less hunger, fewer cravings |
| Cortisol | Reduction (long-term) | Reduced stress, better sleep, lower inflammation |
| Testosterone | Increase (men) | Increased muscle mass, improved libido |
| T3/T4 (thyroid) | Possible T3 decrease | Monitor on long-term strict keto |
| HGH (Growth hormone) | Increase | Cellular regeneration, muscle mass, anti-aging |
Keto and the Thyroid — What Must Be Monitored
The thyroid is sensitive to carbohydrate restriction — especially the T3 hormone (the active form). In some people, long-term strict keto can reduce T3. The solution: the cyclical variant (CKD) with periodic quality carbohydrate refeeds maintains optimal thyroid function.
If you do keto for more than 3–4 consecutive months, run a full panel: TSH, free T3, free T4, fasting insulin, fasting glucose, HbA1c, full lipid panel with LDL-P (particles), not just total LDL. Data leads, not sensations.
Controversies, Contraindications and Warnings
Keto is not suitable for everyone in all circumstances. Honesty requires presenting the limits, contraindications, and areas of controversy too.
Sweeteners in Keto — Which Are Safe
Keto is not a magic bullet.
It is a tool.
The information in this guide represents the result of 30 years of study, practical testing, and working with hundreds of clients. It is not the opinion of a theoretical scientist — it is the results of a practitioner who has lived every protocol described. Keto works. But it only works when it is understood and applied correctly.
