The Claim
Modified alternate-day fasting reduces body weight by an average of 5.18 kg, waist circumference by 3.55 cm, systolic blood pressure by 7.24 mmHg, and diastolic blood pressure by 4.70 mmHg in adults with overweight or obesity over interventions lasting 4 to 104 weeks.
What the research says
Supports is higher
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 adults with overweight or obesity, modified alternate-day fasting results in an average reduction of 5.18 kg in body weight, 3.55 cm in waist circumference, 7.24 mmHg in systolic blood pressure, and 4.70 mmHg in diastolic blood pressure after interventions lasting 4 to 104 weeks.
See the scientific wording
Modified alternate-day fasting reduces body weight by an average of 5.18 kg, waist circumference by 3.55 cm, systolic blood pressure by 7.24 mmHg, and diastolic blood pressure by 4.70 mmHg in adults with overweight or obesity over interventions lasting 4 to 104 weeks, with high-certainty evidence, indicating it is among the most effective intermittent fasting strategies for improving key cardiovascular risk factors.
When food is not eaten for extended periods, the body uses up its stored sugar first, then starts breaking down fat for energy. This process produces ketones, which help the body use fat more efficiently and reduce insulin levels. Lower insulin allows more fat to be burned, shrinking fat stores in the waist and body. At the same time, less fat in the blood and improved blood vessel function lower blood pressure.
What the research says
1 studyThis study found that eating very few calories every other day helped people lose weight, shrink their waist, and lower their blood pressure — exactly what the claim says. The numbers match perfectly, and the evidence is strong.
