The Money Diet

Martin Lewis is the most trusted consumer finance voice in the UK, and this guide earns that trust with tiered, immediately actionable strategies for cutting bills, managing debt, and building savings. The £6,000 annual savings claim is ambitious but grounded in real tactics. The hard limit is geography: if you're not a UK resident, the product-specific advice (British banks, insurers, regulators) loses most of its punch, and some rates are dated from the 2004 original.
