Have you been skipping the gym lately? No judgment: So you overdid it on gingerbread lattes at Starbucks or grabbed too many fast-food meals after marathon shopping trips? No biggie—as long as you stay active in other ways. "A lot of people skip workouts completely when the holidays get busy and promise they’ll exercise in January,” says Mike Donavanik, a personal trainer in Los Angeles. “But it’s that much harder to motivate when you’ve skipped the gym for two-plus weeks.” While you don’t have to maintain your exact same exercise routine, keeping your body in motion will help you balance out the indulgences and start the year strong. To help you do that on the quick, we’ve rounded up a dozen research-backed ways to get more out of your workouts and improve your metabolism to boot.
How much of a deficit? A 500 calorie a day deficit is sustainable for some while leaning down, but any deficit will do. A 1000 calorie a day deficit is aggressive and difficult to maintain. No matter what, don’t drop your calories below 1000 per day, even if you think it will lead to faster weight loss. You’ll be losing muscle at that point, and sacrificing your health and sanity. Not worth it.
The Biggest Loser program has come under attack with recent revelations that its amazing, as-seen-on-TV results are both pharmaceutically assisted and likely to reverse. Living proof that the medical community’s understanding of weight loss is still evolving: The diet still stands in third place on US News’ & World Report’s list for Best Fast Weight Loss.
Say cheese! Adding some extra calcium to your diet could be the key to getting that flat stomach you’ve been dreaming about. Over just 12 months, researchers at the University of Tennessee, Knoxville found that obese female study subjects who upped their calcium intake shed 11 pounds of body fat without other major dietary modifications. To keep your calcium choices healthy, try mixing it up between dairy sources, calcium-rich leafy greens, fatty fish, nuts, and seeds.
You know the drill: Replace refined, overly processed foods with more natural, whole foods. Sure, all foods fit, but they don’t all fit equally. Here’s why: Every time you eat, your metabolism increases as your body works to process your meal. Studies that compare the metabolic boost of calorie-matched whole foods to processed ones find that your body can burn up to 50 percent more calories after a meal made with more real food ingredients compared to a similar meal made with more processed fare. The fact is, your body has to work harder to break down whole foods in order to grab the raw materials it needs so if you exist on a lot of packaged foods and fast foods (think: chips, donuts and drive-thru fare), it’s going to be tougher to lose weight and keep those pounds from coming back.
While you may be tempted to eat as few calories as possible to lose weight more quickly, as mentioned above, it’s important that you don’t cut more than 1,000 calories from your daily diet or eat fewer than 1,200 calories a day — even if that means your energy deficit is smaller than 1,000 calories. Eat too little and you’ll slow down your metabolism and put yourself on track to regain the weight — often with a few extra pounds.
Unintentional weight loss can occur because of an inadequately nutritious diet relative to a person's energy needs (generally called malnutrition). Disease processes, changes in metabolism, hormonal changes, medications or other treatments, disease- or treatment-related dietary changes, or reduced appetite associated with a disease or treatment can also cause unintentional weight loss. Poor nutrient utilization can lead to weight loss, and can be caused by fistulae in the gastrointestinal tract, diarrhea, drug-nutrient interaction, enzyme depletion and muscle atrophy.
