The Claim
Among generally healthy adults aged 41–70, an 18-week personalized nutrition program caused a mean weight loss of 2.46 kg and a mean waist circumference reduction of 2.35 cm, which were significantly greater than the changes observed with standard USDA dietary advice.
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 aged 41 to 70, a personalized nutrition program over 18 weeks led to an average weight loss of 2.46 kilograms and a waist reduction of 2.35 centimeters, which was greater than the changes seen with standard USDA dietary advice.
See the scientific wording
Among generally healthy adults aged 41–70, an 18-week personalized nutrition program resulted in a mean weight loss of 2.46 kg and waist circumference reduction of 2.35 cm, significantly greater than the minimal change observed with standard USDA dietary advice, indicating that individualized dietary guidance may enhance central adiposity reduction.
When people eat foods chosen based on their unique blood sugar and gut bacteria patterns, their gut microbes shift to types that produce beneficial chemicals, which lowers fat in the blood and makes them feel fuller longer. This causes them to eat fewer calories without trying, and their body starts burning stored fat, especially around the waist.
What the research says
1 studyStudy: Effects of a personalized nutrition program on cardiometabolic health: a randomized controlled trial
People who got a custom diet plan based on their blood and gut bacteria lost about 2.5 kg and shrunk their waist by 2.4 cm, while those who just followed regular government diet advice barely changed. So yes, custom diets worked better.
