The research, conducted by the Agricultural Research Service (ARS) of the USDA, measured energy value and found a 5.9% reduction in calories per serving.
Researchers at Purdue University found that rats consuming fat substitutes gained weight and developed more fatty tissue compared to those on a regular high-fat diet. The study suggests that using fat substitutes as part of a long-term weight loss strategy may not be effective due to disrupted taste-calorie relations.
A series of studies found that specific dietary and lifestyle changes have strong associations with long-term weight gain. Modest changes in diet, such as focusing on carbohydrate quality and minimizing processed foods, were linked to significant weight gain over 20 years.
A study published by the American Psychological Association found that rats on high-fat diets gained more weight after eating low-calorie potato chips made with fat substitutes. The study suggests that relying on fat substitutes for weight loss may not be effective and could even lead to weight gain.
Researchers at Baylor College of Medicine identified the α3β4 nicotinic receptor as a key player in the appetite suppression pathway. When nicotine binds to this receptor, pro-opiomelanocortin neurons are activated, leading to reduced food intake.
A long-term study of 1,749 women found no link between taking the combined contraceptive pill and weight gain. Women who took the pill did not put on more weight than their peers who never took it, with ageing and smoking being the only factors affecting weight.
A new study finds that pregnant women who gain too much weight are more likely to have newborns with high body fat, regardless of pre-pregnancy weight. This increased obesity risk exists even when birth weight is normal and may be associated with higher childhood obesity rates.
A Boston University School of Medicine study found that higher adherence to the DASH diet reduced excess weight gain in adolescent girls over a 10-year period. The study, which examined a racially diverse sample of girls aged nine and 10, discovered that those with the highest intake of DASH-like food groups had smaller gains in BMI.
A low-cost healthy lifestyle program, including self-weighing weekly or monthly, has been shown to prevent excessive weight gain in pregnant women with pre-existing overweight. Regular monitoring of weight gain and simple health messages can reduce pregnancy complications, such as gestational diabetes and birth complications.
Women who gained 2-3 BMI units between the first and second pregnancy were more likely to develop GDM in the second pregnancy. Conversely, women who lost over 6 pounds between pregnancies reduced their risk of developing GDM by approximately 50%. The association was strongest in women who were overweight or obese in their first pregnancy.
A prospective study of 59,000 African American women found that those with diets rich in vegetables and fruit gained less weight than those with diets low in these foods. This association was strongest among younger women, who experienced significant weight gain over the 14-year period.
Researchers found that women who gained more than the recommended weight during pregnancy were three times as likely to be overweight or obese. Regular monitoring of weight in pregnancy may need to be reconsidered to prevent these health problems.
A Northwestern University study found that people who go to bed late and sleep in eat more fast food, fewer fruits and vegetables, and weigh more than those with earlier sleep times. The extra calories consumed can lead to significant weight gain if not balanced by physical activity.
Research reveals that immigrants and their U.S.-born children prioritize unhealthy American foods to prove their American-ness and avoid social exclusion. This behavior can lead to poorer health outcomes due to the prevalence of high-calorie, fatty American meals.
