The Claim

In physically active adults aged 24–27, six weeks of either a low-carb high-fat diet or 16:8 intermittent fasting results in modest reductions in body fat percentage (1.3–2.1%) and resting heart rate (3–5 bpm), and these reductions are not statistically different from those observed with fast continuous training or high-intensity interval training.

Support is ahead, but a single strong opposing study can change this.

These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.

In plain English

In physically active adults aged 24–27, six weeks of a low-carb high-fat diet or 16:8 intermittent fasting reduces body fat percentage by 1.3–2.1% and resting heart rate by 3–5 bpm, with no statistically significant difference compared to fast continuous training or high-intensity interval training.

See the scientific wording

In physically active adults aged 24–27, six weeks of either a low-carb high-fat diet or 16:8 intermittent fasting results in modest reductions in body fat percentage (1.3–2.1%) and resting heart rate (3–5 bpm), but these changes are not statistically different from those observed with fast continuous training or high-intensity interval training, suggesting that dietary and exercise interventions of this duration produce similar effects in already active individuals.

Why this might work

When the body uses more energy than it takes in, it breaks down stored fat for fuel, which reduces body fat. At the same time, the heart slows down because the body doesn't need to work as hard to supply energy to tissues.

  1. Study: EFFECT OF LOW-CARB HIGH-FAT DIET AND 16:8 INTERMITTENT FASTING VERSUS FAST CONTINUOUS TRAINING AND HIGH INTENSITY INTERVAL TRAINING ON BODY FAT PERCENTAGE AND RESTING HEART RATE OF PHYSICALLY ACTIVE ADULTS OF PUNJAB

    In young, active people, eating low-carb or only during an 8-hour window lowered body fat and heart rate a little, but so did regular cardio or intense workouts—none worked significantly better than the others.
