Artificial Sweeteners: What Do Studies Really Show? [2025 Review]
6:16

Menno Henselmans

Controlled human trials show no adverse health effects from artificial sweeteners at typical intake levels when used to replace sugar.

High-quality human studies support that artificial sweeteners are safe and can help reduce calorie intake when used to replace sugar, but observational studies misattribute health issues due to reverse causality.

Best Diet Confirmed by 5,248,916 Person-Year Study
10:09

Dr Brad Stanfield

Food source quality matters more than low-fat or low-carb labels for heart health, according to observational studies.

Evidence supports that the quality of foods, not fat or carb ratios, is the primary factor influencing heart disease risk.

1 Tablespoon Before Bed KILLS Cortisol In 2 Minutes (Dr. Bright)
32:23

Max German

Dietary fat does not suppress cortisol via HPA feedback; glucose increases it, while fat shows no effect compared to water.

Evidence contradicts the claim that fat reduces cortisol, showing no suppression compared to water, while glucose clearly elevates it.

Optimal volume & deloading: 2 new studies for max gains
10:11

Menno Henselmans

Higher volume may slightly increase muscle growth, but deloading shows no benefit at low volumes; individual responses vary widely.

Evidence is inconsistent, with some support for marginal gains from higher volume and no benefit from deloading at low volumes, but most findings lack strong confirmation.

Defending Science-Based Lifting
13:53

House of Hypertrophy

Total protein, creatine, training volume, and proximity to failure drive muscle growth; equipment type and timing matter less than consensus science shows.

The available evidence strongly supports key science-based lifting principles, with minimal contradiction across high-quality studies.

‘High Dose Vitamin D’s Steroid-like Effect! Crazy!’
21:59

Physionic

Vitamin D may support muscle growth in older adults and alter metabolic signals in mice, but human evidence for fat loss or steroid-like effects is lacking.

Some human studies show vitamin D can increase muscle fiber size in deficient older adults, but claims of fat loss, metabolic boosts, or steroid-like effects are not supported by high-quality evidence.

Completely WRONG About Salt (New Study)
12:43

Dr Brad Stanfield

Reducing sodium and increasing potassium intake lowers blood pressure, stroke, and death risk without harm at low levels, according to robust clinical evidence.

High-quality clinical trials confirm that lowering sodium and boosting potassium significantly improves heart health, with no evidence of harm from low sodium intake.

McDonald's Got CAUGHT! No Wonder Their CEO Won't Eat It…
22:40

Max German

Some food additives show biological effects in studies, but human evidence is limited and inconsistent.

Evidence for harm from additives like carrageenan and soybean oil is partially supported in animals and cells, but human data is sparse and conflicting.

One Nutrient Deficiency Explains Premature Gray Hair
6:08

Siim Land

B12 deficiency is linked to premature graying in some cases, but reversal is rare and other factors like genetics and other nutrient deficiencies play major roles.

B12 deficiency is associated with premature graying in observational studies, but evidence for reversal is limited to rare case reports and does not establish causation.
