The studies included were well done, so the link between skipping breakfast and health problems is probably real and not just due to bad study design.
Scientific Claim
The quality of included observational studies was generally moderate to high (NOS ≥7), reducing the likelihood that methodological flaws explain the observed associations between breakfast skipping and metabolic syndrome components.
Original Statement
“The quality of the research was evaluated using NOS. The included research scores were greater than 6 points, indicating that the research quality was medium or above (Table 1).”

Association of Skipping Breakfast with Metabolic Syndrome and Its Components: A Systematic Review and Meta-Analysis of Observational Studies
The researchers checked how good the studies were and only used the better ones, so the link between skipping breakfast and health problems is likely real, not just a mistake in how the studies were done.
