A different way of viewing weight loss identifies the problem as not one of consuming too many calories, but rather the way the body accumulates fat after consuming carbohydrates—in particular the role of the hormone insulin. When you eat a meal, carbohydrates from the food enter your bloodstream as glucose. In order to keep your blood sugar levels in check, your body always burns off this glucose before it burns off fat from a meal.
Be choosy about carbs. You can decide which ones you eat, and how much. Look for those that are low on the glycemic index (for instance, asparagus is lower on the glycemic index than a potato) or lower in carbs per serving than others. Whole grains are better choices than processed items, because processing removes key nutrients such as fiber, iron, and B vitamins. They may be added back, such as in “enriched” bread.
In what is perhaps the biggest buzzkill of all time, sex doesn’t quite count as cardio or burn a significant amount of calories: Women burn about 3.6 per minute. "It’s still a good idea," Dr. Seltzer says, citing the activity’s other benefits, like increasing the output of the neurotransmitters serotonin and dopamine, which naturally reduce food cravings.
Ready to step it up with your Fitbit tracker and set some new health and fitness goals? That’s awesome! Cue the fireworks! But if your ultimate goal is to lose weight, unfortunately, activity alone isn’t going to get you there—you also have to change what you eat. That does not mean you need to do a cleanse or detox. But it is possible to get a jump on weight loss, the smart and healthy way. Fitbit Dietitian Tracy Morris developed this kickstart one-week meal plan to help her clients see results, fast. Disclaimers: Please don’t try to lose more than 2 pounds per week, or dip below 1200 calories per day, which can compromise your metabolism. This is not a long-term plan, so you definitely don’t want to eat this way every week. But it’s a great way to kick off a weight loss goal, with specific meal and snack ideas, so you’ll see an initial drop—and be extra motivated to keep the momentum going this year. Increase your drive to succeed, and see how many consecutive days your can stay on track, by using Fitbit’s food logging feature.
