This high-fat, adequate-protein, low-carb fad diet sends the body into a state of ketosis, in which the body uses stored fat for energy. Research published in Clinical Cardiology suggests the ketogenic, or “keto,” diet can be an effective weight loss method, but to be successful, you must follow the plan consistently with no cheat days — otherwise, you’re just eating a high-fat diet that may be high in unhealthy fats for no reason.

#2 – Count your calories, at least for the first week or two.  You’d be amazed in what you think is healthy and is not.  I was drinking a skinny vanilla latte and a reduced fat cinnamon swirl coffee cake for breakfast every day, and that was over 500 calories.  Not smart, not to mention I was hungry a short while after breakfast, which brings me to #3.
Cons: Eating this way perpetuates the outdated idea that dietary fat is the enemy of body fat. And it isn’t necessarily better than other diets: One study in the American Journal of Clinical Nutrition compared high-protein, normal protein, high-fat, and low-fat diets, and found no significant difference in fat loss among the groups at six months or two years (though all did result in some fat loss). What’s more, while the low-fat group was supposed to keep its intake of the macro at 20%, actual intake was closer to 26-28%, suggesting that sticking to a strict low-fat diet is rather difficult and potentially unrealistic for most.
Many people struggle with being overweight, or even obese. It’s a common topic at office visits. As a doctor, I know that excess weight is associated with potentially serious health conditions —  high blood pressure, high blood sugar, high cholesterol —  not to mention sleep apnea, fatty liver disease, and back and knee problems, among other things. Patients may also worry about their appearance.
Seek out restaurants and venues where you can stay on track. Many restaurants offer nutritional information and calorie content on their menus, and it's often possible to modify your choices. Get the salad dressing on the side or hold the butter. Substitute vegetables for fried foods. Even starting the meal with a green salad can make you eat less of the high-calorie main dish while adding some vitamins and fiber to the meal.
Katie’s weight has been a challenge her entire life. But after having two boys, she reached an all-time high: 253 pounds. That was when she decided to make a change, but it didn’t happen right away. For the next three years, she dieted and bounced between losing and gaining 50 pounds. Her real weight loss journey began in 2009, when she used calorie counting and running to take off 125 pounds. Today, she writes about maintaining that loss, running, being a mother, and managing a bipolar diagnosis. Visit the blog.
