• Pure MCTs are more effective for weight management than mixed MCT/LCT products
• Start with 1 teaspoon and gradually increase to avoid digestive discomfort
• Individual responses vary based on metabolic health and APOE ε4 genetic status

Understanding MCT oil: the basics

Medium-chain triglycerides (MCTs) are unique fatty acids with carbon chains of 6-12 atoms, making them easier to digest than long-chain triglycerides (LCTs). Originally developed for medical nutrition therapy, MCTs have gained popularity for their metabolic benefits.

“MCT oil provides a unique energy source that can benefit both athletes and those with certain metabolic conditions,” explains Dr. Sarah Johnson, registered dietitian specializing in ketogenic nutrition. “Unlike long-chain fats, MCTs bypass the lymphatic system and are directly transported to the liver for rapid energy conversion.”

MCT types comparison

Historical context

MCT oil was first developed for patients with malabsorption disorders in the 1950s. Its ability to bypass normal digestive processes made it valuable for those with compromised digestive systems. Today, it’s widely used in ketogenic diets, sports nutrition, and cognitive health protocols.

Core benefits of MCT oil in coffee

Enhanced cognitive function

Recent research from 2023-2025 has refined our understanding of MCT oil’s cognitive benefits. A 2024 systematic review published in the Journal of Alzheimer’s Disease found that MCT supplementation improved general cognitive function, particularly in APOE ε4 negative individuals with existing cognitive impairment.

“The evidence suggests that treatment with MCT could improve general cognitive function in APOE ε4 negative cognitive impaired patients,” notes the 2024 study. “Better characterized clinical studies are warranted before making a definitive conclusion on the use of MCT for MCI and AD management.”

According to nutritionist Dr. Eric Berg (2024), “Ketones aren’t just a preferred energy source for brain cells, they also increase blood flow to your central nervous system. This supports healthy tissue oxygenation and nutrient exchange, which has neuroprotective effects linked to a lower risk of dementia.”

Benefits evidence scale (1-5)

• Improved focus and attention: ★★★★☆ (Strong evidence)
• Memory enhancement: ★★★☆☆ (Moderate evidence)
• Neuroprotection: ★★★☆☆ (Moderate evidence)
• Alzheimer’s symptom reduction: ★★☆☆☆ (Emerging evidence)

Weight management and metabolism

A 2024 meta-analysis published in Clinical Nutrition found that “diets enriched with MCTs are more effective in achieving weight reduction (WMD: -1.53%; 95% CI: -2.44, -0.63; p < 0.01), particularly those containing pure MCTs (WMD: -1.62%; 95% CI: -2.78, -0.46; p < 0.01), compared to long-chain fatty acids (LCTs) enriched diets.”

The study also noted that “MCTs-enriched diets were associated with significant reductions in blood triglyceride levels and Homeostatic Model Assessment for Insulin Resistance (HOMA-IR) scores, compared to LCTs-enriched diets.”

Registered dietitian Imashi Fernando explains, “The shorter the chain, the faster your body is able to break a fat down for energy. So MCTs are easier for your body to convert to energy than long-chain triglycerides.”

Case study: office worker

Sarah, a 38-year-old office worker, struggled with mid-morning energy crashes and snack cravings. After adding 1 tablespoon of MCT oil to her morning coffee, she reported sustained energy until lunch and reduced snacking. Over three months, she lost 7 pounds without other dietary changes.

Enhanced athletic performance

A 2018 study published in PLoS One found that “MCTs enhance exercise endurance through increased mitochondrial biogenesis and metabolism.” The research demonstrated that MCT supplementation improved exercise performance by:

• Increasing mitochondrial capacity
• Enhancing fat oxidation during exercise
• Reducing lactate buildup
• Preserving glycogen stores

Case study: recreational athlete

Michael, a 42-year-old recreational cyclist, incorporated MCT oil into his pre-ride coffee. He noticed improved endurance on longer rides and better recovery afterward. His average ride distance increased by 15% over two months of consistent use.

Appetite regulation and satiety

Research published in Frontiers in Nutrition (2023) confirmed that MCTs have significant effects on appetite regulation. The study found that MCT consumption led to:

• Reduced ghrelin (hunger hormone) levels
• Increased peptide YY and GLP-1 (satiety hormones)
• Lower overall caloric intake in subsequent meals
• Extended time between meals

“MCTs affect the endocrine system and have been found to reduce the release of the hunger hormone ghrelin while, at the same time, stimulating the production of leptin, also known as the satiety hormone,” notes Dr. Berg.

Ketosis support

For those following ketogenic diets, MCT oil provides a reliable way to increase ketone production without excessive carbohydrate restriction. A 2024 study in the American Journal of Physiology-Endocrinology and Metabolism found that “consumption of MCT increases postprandial ketogenesis and metabolic rate and reduces plasma glucose levels in humans.”

Importantly, the study noted that “these responses persist in individuals with obesity and are maintained following chronic MCT supplementation.”
