UN-backed experts say there have been improvements in nutrition and food supplies in Gaza since the ceasefire, but 100,000 people still experienced catastrophic conditions last month.
In August, the Integrated Food Security Phase Classification (IPC) which monitors and classifies global hunger crises said that half a million people - about a quarter of Gaza's population - lived in areas suffering from famine.
The UN and other humanitarian agencies have been able to increase food getting into Gaza since October's ceasefire between Israel and Hamas.
Israel's foreign ministry said the IPC report was deliberately distorted and doesn't reflect the reality in the Gaza Strip.
The latest IPC analysis suggests that a month ago, half a million Gazans were still facing emergency conditions and more than 100,000 were still under the highest level of food insecurity - IPC Phase 5 - experiencing catastrophic conditions.
It projects that number will continue to decrease but stressed the situation remains highly fragile. IPC Phase 5 signifies the most extreme level of food insecurity, labelled famine for an area or catastrophe when referring to households. The report said no areas in Gaza were now classified as in famine.
Israel rejected the original findings of famine by the IPC and has continued to criticise its methodology.
Cogat, the Israeli military body which controls Gaza's crossings, said the number of trucks with food aid entering each week went beyond what the UN had determined it needed.
“The report relies on severe gaps in data collection and on sources that do not reflect the full scope of humanitarian assistance,” the body said in a statement.
Responding to the Cogat criticism, the IPC said publicly available data from UN sources and Cogat had been used for the analysis.
The IPC said acute malnutrition was at critical levels in Gaza City and serious in Deir al-Balah and Khan Younis.
The situation is expected to remain severe but the number of people facing the most severe conditions is predicted to fall to 1,900 by April, according to the report. But the IPC warned that, if there were renewed hostilities, the entire Strip would be at risk of famine.
Key drivers of food insecurity include restricted humanitarian access, displacement of more than 730,000 people, and the destruction of livelihoods - with over 96% of crop land in Gaza being destroyed or inaccessible.
Israel imposed a total blockade on aid deliveries to Gaza at the start of March this year, which was eased in May, stating it wanted to pressure Hamas to release hostages.
Unwra, the UN agency for Palestinian refugees, indicated that while the report stated Gaza was no longer in famine, the situation remained critical and called for sustained humanitarian access.
