The Claim
A low-carbohydrate diet (50–130 g carbohydrate per day) for 16 weeks caused a mean weight loss of 10.9 kg in patients with diabetic cardiomyopathy, compared to a 0.4 kg weight gain in those receiving usual care.
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.
Patients with diabetic cardiomyopathy who ate a low-carbohydrate diet (50–130 grams of carbs per day) for 16 weeks lost an average of 10.9 kilograms, while those who ate as usual gained 0.4 kilograms.
See the scientific wording
A low-carbohydrate diet (50–130 g carbohydrate per day) for 16 weeks resulted in a mean weight loss of 10.9 kg in patients with diabetic cardiomyopathy, compared to a 0.4 kg weight gain in those receiving usual care, suggesting that carbohydrate restriction may be an effective strategy for reducing body weight in this population despite no caloric restriction.
When carbohydrate intake drops, the body produces less insulin, which tells fat cells to release stored fat into the blood. The liver turns this fat into ketones, which the heart uses for energy instead of sugar. At the same time, the kidneys start removing more salt and water, which reduces fluid weight. Together, these changes cause the body to lose fat and water without needing to eat fewer calories.
What the research says
1 studyPeople with a heart condition linked to diabetes who ate fewer carbs lost about 11 pounds on average, while those who ate normally gained a little weight—even without counting calories. This suggests cutting carbs can help lose weight in this group.
