The Claim
A 12-week web-based intermittent fasting program using weekly 407-kcal meal replacements, online guidance, and app messaging resulted in a mean weight loss of 1.6 kg greater than minimal care in Japanese adults with overweight or obesity (BMI 23–<35), with 79% adherence and no serious adverse events.
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 Japanese adults with overweight or obesity, a 12-week online program using weekly 407-kcal meal replacements, guidance, and app messages led to 1.6 kg more weight loss than minimal care, with 79% adherence and no serious side effects.
See the scientific wording
A 12-week web-based intermittent fasting program using weekly 407-kcal meal replacements, online guidance, and app messaging led to a mean weight loss of 1.6 kg greater than minimal care in Japanese adults with overweight or obesity (BMI 23–<35), with high adherence (79%) and no serious adverse events, suggesting this structured approach can promote modest weight loss in this population.
Eating fewer calories than the body needs causes fat cells to release stored fat for energy. This lowers insulin levels, which stops the body from storing more fat and lets it burn existing fat instead.

1 studyThis online program helped people in Japan lose about 1.6 kg more than those who just got basic health tips, without any serious problems. It worked because people stuck with it and got weekly low-calorie meals plus reminders.
