A. "Because no matter how you drop pounds -- whether it's through dieting, exercise, or a combination of both -- you will inevitably lose some muscle, and that slows down your basal metabolic rate," explains Jackie Newgent, R.D., a New York City based nutrition consultant. Strength training with weights throughout your weight loss period can help preserve a lot but not necessarily all of it. "Then, when you regain the weight, you'll most likely put on more fat than muscle, which reduces your percentage of lean body mass, leaving you with a slower metabolism than you had prior to the weight loss."
Of carbs and protein, that is. Carbs certainly aren’t the enemy; you can totally enjoy carbs and still lose weight. The trick is to choose something complex (like brown rice, quinoa, or whole grain bread) or something refined (like white rice, white pasta, and white bread), and pair it with a protein. So if you’re having crackers for a snack, make sure you also eat some almonds or a stick of string cheese. “I always incorporate a protein and carbohydrate at every meal,” Jim White, RD, ACSM Health, and owner of Jim White Fitness & Nutrition Studios told us in our 30 No-Diet Diet Tricks article. “It can curb your appetite and it slows down the glycemic index of some of your higher sugar foods.”
Cortisone as an oral drug is another common culprit (e.g. Prednisolone). Cortisone often causes weight gain in the long run, especially at higher doses (e.g. more than 5 mg Prednisolone per day). Unfortunately, cortisone is often an essential medication for those who are prescribed it, but the dose should be adjusted frequently so you don’t take more than you need. Asthma inhalers and other local cortisone treatments, like creams or nose sprays, hardly affect weight.
Your New Year's resolution diet should be based on a well-balanced eating plan that fits your lifestyle, rather than a weird fad replete with food restrictions. That's according to U.S. News & World Report's best diet rankings for 2018. The two diets that tied for the top spot -- the Mediterranean Diet and the DASH Diet -- fit that bill because they feature real food and reasonable, flexible guidelines, experts said.
