If you’ve been eating fast food for years, get real about your approach: You’re probably not going to stick to an organic, gluten-free, paleo overhaul for very long. "You want to change as little as possible to create calorie deficit," says Dr. Seltzer, who insists the best way to support sustainable weight loss is to incorporate small changes into existing habits. So instead of giving up your daily BLT bagels in favor of an egg-white wrap, try ordering your sandwich on a lighter English muffin. Or say you eat a snack bar every afternoon: Swap your 300-calorie bar for a 150-calorie alternative. "Your brain will feel the same way about it, so you won’t feel deprived," he says.
With this eating style, you’re looking at a lot of menu planning and preparation. A review published in August 2017 in Nutrients suggests the diet could lead to weight loss, but the Academy of Nutrition and Dietetics warns the plan could also cause certain nutrient deficiencies, such as in calcium and vitamin D. (3,4) And, therefore, according to an article published in the January–February 2016 issue of the Royal Australian College of General Practitioners, anyone at risk for osteoporosis should avoid it.

To encourage ketone production, the amount of insulin in your bloodstream must be low. The lower your insulin, the higher your ketone production. And when you have a well-controlled, sufficiently large amount of ketones in your blood, it’s basically proof that your insulin is very low – and therefore, that you’re enjoying the maximum effect of your low-carbohydrate diet. That’s what’s called optimal ketosis.
Meal prep, short for meal preparation, is the process of planning and preparing your meals ahead of time. You can meal prep one day ahead, or take one day to prepare lunch and/or dinner for an entire week. While most meal prep only one or two meals, you can easily meal prep breakfast, lunch and dinner, even snacks for the week ahead. It’s entirely up to you!
Topping foods with heavy sauces or condiments could add extra calories and often little nutritional value. For example, ketchup often has a high amount of sugar. According to Monica Auslander, a registered dietitian and founder of Essence Nutrition, one teaspoon of ketchup is equal to eating a sugar packet. “It’s deceiving because it has no fat, so people think they can enjoy freely,” she says. “Unfortunately, we now know that sugar is far more insidious than fat.” Fortunately, there are healthier lower-calorie options such as pesto, hummus, and DIY recipes. These are the condiments that are bad for your health.
“This is a great way of eating that I highly recommend to many clients, and I even model in my own life,” says Elizabeth Shaw, RDN, who is in private practice in San Diego and is the co-author of Fertility Foods Cookbook. “Since the premise of the diet is designed to help people who have high blood pressure, low-sodium foods are recommended. But considering that most Americans exceed their daily sodium levels anyway, it’s not surprising that dietitians recommend this style of eating for treating many different conditions, such as heart disease and obesity.”
The fad military diet consists of low-calorie, odd food pairings such as bun-less hot dogs with banana, carrots, and broccoli. “Any diet like the military diet that severely limits the amount of calories you consume or eliminates one or more entire food groups puts any individual at risk for nutrient deficiencies,” says Kyle. “This can be more harmful than holding onto those 10 extra lb you’re trying to lose.” (32)
Switch to Lighter Alternatives. Whenever you can, use the low-fat versions of salad dressings, mayonnaise, dairy products, and other products. "You can trim calories effortlessly if you use low-fat and lighter products, and if the product is mixed in with other ingredients, no one will ever notice," says Magee. More smart substitutions: Use salsa or hummus as a dip; spread sandwiches with mustard instead of mayo; eat plain roasted sweet potatoes instead of loaded white potatoes; use skim milk instead of cream in your coffee; hold the cheese on sandwiches; and use a little vinaigrette on your salad instead of piling on the creamy dressing.
Notes: Chop the sweet potatoes and halve the Brussels sprouts, and place on a sheet pan. Drizzle with 2 teaspoons olive oil, season with salt and pepper, and toss to coat. Roast at 450°F (230°C) until tender, about 15 minutes. Season the steak with salt and pepper. In a frying pan over medium-high heat, warm 1 teaspoon olive oil. Cook the steak until done to your liking, about 3 minutes per side for medium-rare. (Consuming raw or undercooked meats may increase your risk of foodborne illness.)
