Scientist say high-protein diets like the low-carb Paleo plan may be the secret to lasting weight loss, according to Examiner.
A new study at the University of Sydney indicates that high protein, low-carb diets like the Paleo diet are better than low-calorie diets for weight loss because they suppress appetite.
Nutritional ecologist David Raubenheimer said the findings offer important insights for battling the global pandemic of obesity and diabetes.
“We can use this information to help manage and prevent obesity, through ensuring that the diets we eat have a sufficient level of protein to satisfy our appetite,” said Raubenheimer, who led the study.
Raubenheimer and his team found that baboons who consumed a high-protein diet maintained their weight even when they ate more calories, underscoring the weight loss benefits of protein without the need for calorie restriction.
The latest study confirms similar research published in the biology journal, FASEB, which monitored 39 adults on a calorie-restricted diet with varying levels of protein.
After 31 days, the group that consumed twice the recommended daily amount of protein lost more weight than the low-protein group while maintaining lean muscle mass.
Professor Raubenheimer concluded by saying the best diet is similar to the Paleo diet: One that limits processed junk and focuses on whole foods.
“A simple rule for healthy eating is to avoid processed foods – the closer to real foods the better,” he said. “Our bodies and appetites are not adapted to biscuits, cakes, pizzas and sugary drinks, and we eat too much of them at our peril.”
Paleo Diet Twice as Effective for Weight Loss
Meanwhile, the low-carb, high-protein Paleo diet is soaring among celebrities, including Robin Wright, Megan Fox, Joe Manganiello, and Tim McGraw (who credits Paleo for his eye-popping 40-pound weight loss).
The Paleo diet emphasizes high-quality animal proteins, healthy fats, low-starch vegetables and fruits, and excludes gluten, sugar, dairy, legumes, alcohol and processed foods. Proponents say the Paleo diet promotes weight loss, and prevents diabetes, cancer, heart disease, depression, and even Alzheimer’s.
Fitness expert Mark Sisson said people who go Paleo will notice health changes almost immediately, including weight loss (without targeted calorie restriction), improved sleep, and more energy. Sisson told Palm Springs Life the Paleo diet enhances weight loss by turning your body into a fat-burning machine.
“Over time, you become good at burning off your own body fat for energy rather than depending on carbohydrates throughout the day,” said Sisson, author of The Primal Blueprint. “It takes about 21 days for your body to switch to this mode of fat-burning, and that’s when you’ll really start to see results.”
Research suggests the Paleo diet accelerates weight loss, reduces blood pressure, and prevents cancer, diabetes, heart disease, depression, and even Alzheimer’s. TV star Jack Osbourne and singer Chad Vaccarino both use the Paleo diet to treat their multiple sclerosis.
A recent study published in the European Journal of Clinical Nutrition indicates the Paleo diet is twice as effective as other diets for promoting weight loss and reducing belly fat.
“Clinical trials have shown the Paleo diet is the optimum diet that can lower the risk of cardiovascular disease, blood pressure, markers of inflammation, help with weight loss, reduce acne, promote optimum health and athletic performance,” said Dr. Loren Cordain, author of The Paleo Diet for Athletes and The Paleo Diet Cookbook.
