When you're at the gym, don't head straight for the treadmills. Tim Rich, personal trainer and district fitness manager at Crunch Gyms in San Francisco says, "you lose steam when you save the weights for last, and that's where the magic happens." Weight-training burns approximately 30 to 50 more calories a day for every pound of muscle you gain, so "when you have more energy you'll be able to lift heavier weights, which helps you burn more fat everywhere, including your belly," he says. And researchers found that, while those who lifted heavy weights lost the same amount of weight as those who only did cardio, the only weight they lost was fat—the cardio queens lost muscle, and that's never good, especially as you get older.
Lastly, to help you stay motivated I recommend you log your weight loss results so that you can gather an average. You will always have good weeks and bad weeks, but it’s the average that counts. Every weigh in (only weigh in once per week) write the pounds lost on your calendar. At the end of 8 weeks add up all the weight loss pounds and divide by 8 for your 8 week average. This will help you stay motivated and see your results. Anytime you have a bad week, think of your weight loss average and know this is all just part of the process.
When you substitute foods, make sure you don’t use the same amount of the substitute as the original without checking caloric equivalence first. For example, if you want to substitute Greek yogurt for cottage cheese, you can actually eat a bit more of the yogurt than the prescribed amount of cottage cheese. Just 1 cup of 2% cottage cheese contains 194 calories, while 1 cup of 2% Greek yogurt contains 150 calories, meaning you can have additional 1/3 cup of the yogurt. Make use of a calorie calculator if you’re not sure about your allowances.
Just this week, a 25,000-person study presented at the European Society of Cardiology Congress in Munich suggested that people on the lowest-carb diets had the highest risk of dying from cancer, cardiovascular conditions, and all other causes. Another study, published this month in the Lancet, also found that people who followed diets that were low in carbs and high in animal proteins had a higher risk of early death compared to those who consumed carbs in moderation. (The opposite was true, however, for low-carb dieters who opted for plant-based proteins over meat and dairy.)
Because people with type 2 diabetes are at an increased risk for cardiovascular disease, there’s a specific concern that the saturated fat in the diet may drive up LDL, or “bad,” cholesterol levels, and further increase the odds of heart problems. If you have type 2 diabetes, talk to your doctor before attempting a ketogenic diet. They may recommend a different weight-loss diet for you, like a reduced-calorie diet. Those with epilepsy should also consult their doctor before using this as part of their treatment plan.
Intermittent fasting has blown up in the past year, but scientists are just starting to figure out how it can help you lose weight. In one study from the University of Illinois at Chicago, researchers compared obese people in a traditional weight loss group and fasting group. For the experiment, the calorie-restricted group simply reduced the amount of calories they ate by 25 percent each day. The fasting group, however, alternated days: they ate 25 percent of the calories they needed one day between 12 and 2 p.m., and then had feast days the next, where they ate 125 percent of their required calories.
Make sure to program your cardio exercise in with your weight training the right way, though — a 2017 study found that performing cardio and weight training workouts on alternate days was far more effective for burning belly fat than stacking the workouts on top of each other in the same session. Put the two together, and watch that unhealthy midsection shrink.
When a person goes off the ketogenic diet and regains much of their original weight, it’s often not in the same proportions, says Kizer: Instead of regaining lean muscle, you’re likely to regain fat. “Now you’re back to your starting weight, but you no longer have the muscle mass to burn the calories that you did before,” she says. “That can have lasting effects on your resting metabolic rate, and on your weight long-term.”
"When going out for fast food, I used to get the large-size value meal. Now, I satisfy a craving by ordering just one item: a small order of fries or a six-piece box of chicken nuggets. So far, I've shaved off 16 pounds in seven weeks, and I'm on track to being thinner than my high school self for my 10-year reunion later this year." —Miranda Jarrell, Birmingham, AL
