A protein-rich diet combined with exercise leads to greater weight loss and fat reduction compared to a high-carbohydrate, lower-protein diet. This study found that dieters on the protein-rich diet lost almost 100% of their weight in fat, while those on the low-protein diet lost 25-30% of their weight as muscle.
A study by Dr. Mihai Covasa and colleagues found that a high-fat diet can reduce the body's sensitivity to cholecystokinin, a hormone that helps regulate appetite, in rats. This reduced sensitivity leads to increased overconsumption of highly palatable foods high in dietary fat.
A new Penn State study found that a balanced diet with both polyunsaturated fatty acids (PUFAs) and monounsaturated fatty acids (MUFAs) is essential for lowering cholesterol levels. The study compared two heart-healthy oils, sunflower oil and olive oil, in a diet designed to reduce blood cholesterol.
A recent study published in the Journal of Nutrition found that individuals with elevated C-reactive protein (CRP) levels cannot lower their LDL-cholesterol numbers with a Step 1 diet, even when soy protein is added. The study suggests that habitual consumption of a Step 1 diet may be beneficial for those with low CRP levels but delete...
Researchers found that subjects following a frozen-entree diet lost more weight and experienced greater satiety due to automatic portion control. In contrast, those following the food pyramid diet struggled with estimating daily calorie intake, leading to less effective weight loss.

Male crickets fed high protein diets engage in more sexual calling and die sooner than those on low protein diets. This is because they spend extra resources on mating behavior, shortening their lifespan. In contrast, males on low protein diets tend to delay calling until later in life, maintaining their body weight for longer.
A low-glycemic load diet was found to be more effective in reducing hunger and improving metabolic rate during weight loss. The diet also showed beneficial effects on several obesity-related risk factors compared to a low-fat diet.

After six weeks, participants on the moderate-fat diet had a healthier heart profile, with reduced cardiovascular risk and improved lipid profiles.
A moderate-fat diet, rich in monounsaturated fats from peanuts and peanut oil, produced a significant reduction in cardiovascular disease risk, with a 14% decrease compared to the low-fat group. The study found that despite weight loss, high fat diets can rebound and cause adverse effects on HDL cholesterol levels during maintenance.
A limited study of six patients found that the Atkins diet helped two children and one young adult remain seizure-free for up to 20 months. The researchers suggest that the diet may be a trial run for individuals considering the ketogenic diet, but its use should be cautious due to the small study size.
A high-saturated-fat diet combined with starch avoidance yielded significant weight loss in a 6-week study, with patients losing 5% of their body weight. The diet restricts calories and focuses on protein from red meat and cheese, while limiting fruits and non-starchy vegetables.
A study published in the Journal of the National Cancer Institute found that rats fed whole tomato powder had a 26% lower risk of prostate cancer death compared to those on control diets. The researchers suggest that whole tomato products and energy balance may offer independent benefits against prostate cancer.
Researchers at Ohio State University Comprehensive Cancer Center found that a diet rich in whole tomatoes, but not supplements, was associated with longer survival rates and reduced risk of prostate cancer. The study also showed that energy restriction did not offer additional benefits over a balanced diet.
Studies link fructose intolerance to IBS symptoms; patients with diet modifications show improved symptoms. Fat consumption is also linked to gastrointestinal disorders, according to a new study.
