A classical ketogenic diet typically provides ~70–80% of calories from fat, ~15–20% from protein, and only ~5–10% (often 20–50 g/day) from carbohydrates. The metabolic shift to ketosis lowers blood glucose and insulin, raises ketone bodies (beta-hydroxybutyrate, acetoacetate), and is being studied for neurological and metabolic conditions. Variants include the Modified Atkins Diet (MAD), Medium-Chain Triglyceride (MCT) ketogenic diet, and the Low Glycemic Index Treatment (LGIT).
Foods to emphasize
Fatty fish (salmon, sardines, mackerel)
Pasture-raised eggs
Avocado and olives
Extra-virgin olive oil, coconut oil, MCT oil
Grass-fed meat and poultry
Full-fat dairy (butter, ghee, hard cheeses)
Nuts and seeds (macadamia, pecan, walnut, chia, flax)
Low-carb leafy greens and cruciferous vegetables
Bone broth and electrolyte-rich foods
Foods to avoid
Sugar and sweetened beverages
Grains and starches (bread, pasta, rice, cereal)
Most fruit (except small portions of berries)
Legumes and beans
Starchy vegetables (potatoes, corn, peas)
Low-fat or sweetened dairy
Vegetable seed oils (soybean, corn, sunflower) in excess
Most processed and packaged foods
Key principles
Carbohydrate intake usually 20–50 g net carbs per day
Adequate protein (~1.2–1.7 g/kg) — not high-protein
Most calories from whole-food fats
Track electrolytes (sodium, potassium, magnesium) to prevent "keto flu"
Best initiated with clinician guidance if on medications for diabetes, blood pressure, or seizures
Typical duration: Often 3–6 months minimum to assess response; medically supervised protocols (e.g. for epilepsy) may be maintained for years.
Why it may help
Prediabetes: Rapid improvements in fasting glucose and HbA1c, often reversing prediabetes within months.
Type 2 Diabetes: Significant HbA1c and fasting glucose reductions in clinical trials. Monitor diabetes medications closely to avoid hypoglycemia.
Insulin Resistance: Most direct mechanism — lowers insulin demand by minimizing carbohydrate load.
Ketogenic therapy is a medical intervention when used for seizure disorders or oncology — work with a clinician or registered dietitian experienced in ketogenic therapy. Not recommended in pregnancy, type 1 diabetes without supervision, pancreatitis, certain fatty-acid oxidation disorders, or active eating disorders.
Anti-Inflammatory Diet
A whole-foods pattern designed to lower chronic, low-grade inflammation by emphasizing omega-3s, polyphenols, fiber, and minimizing ultra-processed foods, sugar, and seed oils.
The anti-inflammatory diet is not a single protocol but a synthesis of the patterns most consistently linked to lower inflammatory markers (CRP, IL-6, TNF-alpha) in human studies — Mediterranean-style eating, oily fish, abundant polyphenols, and low intake of ultra-processed foods, refined sugar, industrial seed oils, and excessive alcohol.
Foods to emphasize
Fatty fish 2–3x/week (salmon, sardines, mackerel, herring)
Extra-virgin olive oil
Berries, cherries, and other deeply colored fruit
Dark leafy greens and cruciferous vegetables
Turmeric, ginger, and culinary herbs
Green tea
Nuts (especially walnuts) and seeds (flax, chia)
Legumes and whole grains
Dark chocolate (≥70% cocoa) in moderation
Foods to avoid
Sugar-sweetened beverages and refined sugar
Ultra-processed snacks and ready meals
Industrial seed oils used at high heat (soybean, corn, sunflower, cottonseed)
Processed and cured meats
Refined flour products
Excess alcohol
Key principles
Cook with olive oil, finish with extra-virgin olive oil
Aim for 25–35 g of fiber per day from whole foods
Eat the rainbow — color diversity ~ polyphenol diversity
Limit added sugar to <25 g/day
Typical duration: A long-term eating pattern.
Why it may help
Prediabetes: Lowers inflammatory markers linked to insulin resistance and metabolic progression.
Type 2 Diabetes: Reduces systemic inflammation that drives insulin resistance and beta-cell dysfunction.
Insulin Resistance: Reduces chronic low-grade inflammation that impairs insulin signaling.
Safe and flexible. Can be combined with Mediterranean, vegetarian, or plant-forward patterns.
Vegan Diet
A fully plant-based eating pattern that excludes all animal products — meat, fish, dairy, eggs, and honey.
A whole-food vegan diet emphasizes vegetables, fruit, legumes, whole grains, nuts, and seeds. It has been associated with improvements in body weight, blood lipids, and glycemic control, and is being studied for autoimmune and inflammatory conditions. It requires deliberate planning for vitamin B12, vitamin D, omega-3 (EPA/DHA), iodine, iron, zinc, and (sometimes) calcium.
Vegan diets can be excellent or deficient — quality depends on planning. Pregnant, breastfeeding, and growing children on vegan diets should be followed by a registered dietitian.
Enhances insulin action at the receptor level via chromodulin, improving glucose uptake.
How it works in more detail
Chromium picolinate appears to enhance the action of insulin, a hormone critical for carbohydrate, fat, and protein metabolism. It is thought to increase insulin sensitivity by binding to a low molecular weight chromium-binding protein (LMWCr), which then amplifies insulin signaling pathways. This effect may involve improved cellular uptake of glucose and a reduction in insulin resistance. Most of the precise molecular mechanisms have been investigated in preclinical models or in vitro studies.
How to use

We aimed to investigate the effect of chromium supplementation on glycemic control indices in patients with type 2 diabetes (T2DM).
Randomized controlled trials examining the effect of chromium supplementation on glycemic control indices and published before February 2020 were detected by searching online databases, including PubMed, Scopus, Embase, Web of sciences and The Cochrane Library, using a combination of suitable keywords. Mean change and standard deviation (SD) of the outcome measures were used to estimate the mean difference between the supplementation group and the control group at follow-up.
Twenty-eight studies reported fasting plasma glucose (FPG), insulin, hemoglobin A1C (HbA1C) and homeostatic model assessment for insulin resistance (HOMA-IR) as an outcome measure. Results revealed significant reduction in FPG (weighted mean difference (WMD): -19.00 mg/dl, 95% CI: -36.15, -1.85, P = 0.030; I2: 99.8%, p < 0.001), insulin level (WMD: -12.35 pmol/l, 95% CI: -17.86, -

Diabetes is a global public health concern with increasing prevalence worldwide. Chromium (Cr), a trace element found in soil, water, and food, has been proposed to have a possible positive effect in glucose metabolism and diabetes mellitus prevention. However, the relationship between trivalent chromium [Cr(III)] exposure, mainly through the consumption of diet supplements, and type 2 diabetes mellitus (T2DM) remains controversial. An extensive systematic review of the current literature on randomized controlled studies (RCTs) was conducted from 1 January 2000, to January 2024 using the databases PubMed, Scopus, ScienceDirect, and Cochrane, with specific keywords and inclusion as well as exclusion criteria. After close screening of the research studies retrieved from the mentioned websites was conducted, the most related studies were included in the final systematic review. The studies were evaluated for the degree of relevance, quality, and risk bias, using appropriate quality assess

Polycystic ovary syndrome (PCOS) affects 1 in 5 women of reproductive age, and is characterized by menstrual irregularities, clinical or biochemical hyperandrogenism, and the presence of polycystic ovary morphology. One of the recommended treatment strategies in the international evidence-based guidelines is lifestyle modification, which includes diet and exercise, with the aim of improving a range of health outcomes. The incurable nature of PCOS reinforces the importance of developing novel and innovative symptomatic relief strategies, which are currently the only available approaches for improving quality of life for these women. Women with PCOS tend to be nutrient deficient in many common vitamins and minerals, thought to be associated with the psychological (depression, anxiety, etc.) and physiological (insulin resistance, diabetes, infertility, etc.) sequelae of the condition. Nutrient supplementation and the integration of complementary medicine as adjuncts to traditional lifesty

Limitations: Limitations include significant heterogeneity among study designs, doses used, and populations studied, which can lead to conflicting results. Many studies are relatively small, and longer-term, larger-scale trials are often needed to confirm initial findings and assess clinical significance. The impact of publication bias may also be a consideration.
