Fewer meals correlate with lower BMI when paired with healthy habits, but food quality and reverse causation complicate the relationship.
Original: They Were Wrong About Fasting (this study misled us)
Evidence suggests meal frequency alone doesn't determine metabolic health—lifestyle behaviors and food quality are stronger drivers.
Quick Answer
The video reveals that a widely cited study claiming eating fewer than three meals per day increases belly fat was flawed because it failed to account for confounding lifestyle factors—those eating fewer meals were more likely to smoke, be inactive, and drink heavily. A larger study of over 50,000 people found the opposite: those eating fewer meals had lower BMI and longer overnight fasts correlated with reduced body fat. The real issue is not meal frequency, but food quality and overall lifestyle habits.
Claims (7)
1. People who eat fewer meals (1–2 per day) tend to have lower body weight than those who eat 3 or more meals.
2. The longer you go without eating at night, the less weight you tend to carry — not because fasting burns fat magically, but because it naturally reduces total food intake.
3. People who eat fewer meals often have other bad habits like smoking or not exercising — so it’s not the meal count that causes belly fat, it’s those other habits.
4. People who are already overweight might eat less because their body doesn’t feel hungry — so it’s not that eating less makes you fat, it’s that being fat makes you eat less.
5. Eating three meals a day doesn't automatically make you healthier or leaner — your body can keep building muscle even if you don't eat all day.
6. Eating three meals of healthy food is not the same as eating three meals of junk food — your body reacts differently.
7. When people switch from snacking to fewer meals, they often eat fewer carbs — which can affect weight, even if total calories stay the same.
Key Takeaways
- •Problem: Many people believe eating three meals a day is the healthiest way to eat, but a popular study that said eating fewer meals causes belly fat was misleading because it didn't consider other bad habits like smoking and inactivity.
- •Core methods: Eating fewer than three meals per day, extending overnight fasting, avoiding processed junk food, reducing snacking frequency.
- •How methods work: Eating fewer meals naturally extends the time without food overnight, which helps the body burn fat instead of storing it; avoiding junk food reduces insulin spikes that cause hunger and fat storage; reducing snacking lowers overall carb intake and stabilizes appetite hormones.
- •Expected outcomes: Lower body mass index (BMI), reduced belly fat, better appetite control, and improved metabolic health without needing to eat three meals a day.
- •Implementation timeframe: Results can be seen within weeks when consistently eating fewer meals, fasting longer at night, and choosing whole foods over processed snacks.
Overview
The problem is the widespread belief that eating three meals per day is the gold standard for metabolic health, based on a flawed epidemiological study that conflated correlation with causation. The solution is to prioritize food quality, longer overnight fasting periods, and lifestyle factors over rigid meal frequency rules, as evidence shows fewer meals can be associated with lower BMI when confounders are controlled.
Key Terms
How to Apply
- 1.Eat only one to two meals per day instead of three, with the last meal ending at least 12 hours before breakfast the next morning to extend overnight fasting.
- 2.Avoid all snacking between meals, including processed foods, sweets, and sugary drinks, to reduce insulin spikes and appetite stimulation.
- 3.Replace hyper-palatable processed foods with whole, unprocessed foods like vegetables, lean meats, eggs, nuts, and legumes at each meal.
- 4.Track your food intake for one week using a simple journal to confirm you are not consuming excess calories or carbs under the guise of 'meal frequency' compliance.
- 5.Monitor changes in hunger levels, energy, and waist circumference weekly to assess metabolic improvements.
When following these steps, individuals will experience reduced hunger between meals, lower insulin levels, decreased abdominal fat, and improved energy stability within 2–4 weeks, without needing to eat three meals per day.

Low meal frequency is correlated with unhealthy lifestyle behaviors (smoking, physical inactivity, heavy alcohol consumption), which independently contribute to central adiposity.
Muscle protein synthesis remains elevated for several hours post-exercise without requiring frequent meals to maintain muscle mass.
Central adiposity and metabolic dysregulation (e.g., leptin resistance) can reduce appetite and lead to decreased meal frequency, creating reverse causation in observational studies.
Eating fewer than three meals per day is associated with lower body mass index (BMI) compared to consuming three or more meals per day.
Consumption of hyper-palatable processed foods, even at matched meal frequency, leads to adverse metabolic outcomes (e.g., elevated insulin, insulin resistance, increased adiposity) compared to whole, unprocessed foods.
