Dr. O’Brien proclaimed that the benefits of the Mediterranean diet as a push away from using animals as a protein source, introducing more fruits and vegetables in meals, while also cutting out butter in favor of using oils cooking. It seemed simple which made me skeptical. I know that in dieting nothing good is easy. When I got back to office I started my research and was surprised to learn that the Mediterranean diet was endorsed by the American Heart Association and Mayo Clinic.
Participants were asked to follow one of three diets; a control diet that was low in fiber and minerals like potassium, calcium, and magnesium, but had a “typical American” fat and protein profile, an experimental diet that was similar to the control diet, but included more fruits and vegetables and fewer sweets, and a third diet that was abundant in fruits, veggies, low fat dairy, lean protein, whole grains, and fiber, but lower in fat, red meat, and sugar.
Lele says that it’s important to remember that, while keto is a “high fat” diet, the goal is to use your body fat as an energy source, not the fat that’s on your plate. “You don’t need to necessarily add more fats to your diet to adhere to keto. For instance, if your dinner consists of avocado, bacon, and eggs, you really don’t need to add butter to that to make it ‘more keto’,” she says.
For those who want to follow a ketogenic-type diet, Dr. Reynolds says it is important to first talk to your doctor and to discuss your goals so you can be sure that this approach is suitable for you given your medical and health history. Ongoing monitoring is needed if you do decide to adopt this very carb approach to eating. Seeing your doctor regularly is important to make sure that your blood pressure, lipids, blood sugar, mood, and medications are within normal ranges as you lose weight. Adjustments are likely going to be necessary from time to time.

One meta-analysis18 incorporating data from 447 participants found that low-carbohydrate diets not only helped individuals lose weight, but also improved their cholesterol. And another meta-analysis,19 citing 17 clinical trials, found that low-carb diets protected against major cardiovascular risk factors. A third study20 including 119 participants found that low-carbohydrate dieters had lower cholesterol than low-fat dieters after one year.
The popular low-carb diets (such as Atkins or Paleo) modify a true keto diet. But they come with the same risks if you overdo it on fats and proteins and lay off the carbs. So why do people follow the diets? "They're everywhere, and people hear anecdotally that they work," McManus says. Theories about short-term low-carb diet success include lower appetite because fat burns slower than carbs. "But again, we don't know about the long term," she says. "And eating a restrictive diet, no matter what the plan, is difficult to sustain. Once you resume a normal diet, the weight will likely return."
What the diet advocate says: ‘We are committed to always being the best weight management program on the planet, but now we’re putting our decades of knowledge and expertise in behavioral science to work for an even greater mission,’ says Mindy Grossman, President and Chief Executive Officer, WW. ‘We are becoming the world’s partner in wellness. No matter what your goal is – to lose weight, eat healthier, move more, develop a positive mind-set, or all of the above – we will deliver science-based solutions that fit into people’s lives.’
If you’re looking to get a jump start on your health and fitness goals this year, you may be thinking about trying the ketogenic diet. Maybe you’ve heard the phrase before — it’s a huge diet buzzword — but aren’t sure what it means. Here’s a primer: The ketogenic diet is an eating plan that drives your body into ketosis, a state where the body uses fat as a primary fuel source (instead of carbohydrates), says Stacey Mattinson, RDN, who is based in Austin, Texas.
