Stephen Colbert may be on to something. UCLA Center for Human Nutrition researchers divided study participants into two groups, each of which were fed a nearly identical low-cal diet for 12-weeks. The only difference between the groups was what they were given to eat as an afternoon snack. One group ate 220-calories of pretzels while the other group munched on 240-calories worth of pistachios. Just four weeks into the study, the pistachio group had reduced their BMI by a point, while the pretzel-eating group stayed the same, and their cholesterol and triglyceride levels showed improvements as well.
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.
"Whether it's an app or paper food logs, tracking what you eat will certainly be eye-opening. Almost everyone consumes more than they think. Write everything down as soon as you're done eating so you don't forget anything. The simple act of recording what you eat will make you eat less. When the calories are in your face, it makes you think twice!" — Martha McKittrick, RD, CDE
Based on my experience in nutrition counseling, most of us tend to snack on foods that aren’t nutrient-dense, but are high in calories. For example, skipping sugary beverages is often the easiest way to lose weight faster. You don’t feel full from drinks — even the ones that do contain calories — so swapping those out for sparkling water or unsweetened tea and coffee is the best place to start. Other major culprits often come in refined grains like cereals, chips, crackers, and cookies.
"Don't skip breakfast—it really is the most important meal of the day. Eat breakfast within 90 minutes of waking, and then have something healthy to eat every three to four hours after that. When we skip breakfast or wait too long to eat in the morning, our bodies start to conserve energy and our metabolism slows down. Skipping breakfast also leads to overeating throughout the day." — Ilyse Schapiro, MS, RD, CDN, author of Should I Scoop Out My Bagel?
"Even though a smart diet is key, exercise can help boost your body's metabolism to shed fat. Through health care providers often recommend brisk walking or jogging, these exercises may not help you see the results you want. Instead, try interval training," shares Dr. Sean M.

Don't get me wrong — exercising at any time is good for you. But evening activity may be particularly beneficial because many people's metabolism slows down toward the end of the day. Thirty minutes of aerobic activity before dinner increases your metabolic rate and may keep it elevated for another two or three hours, even after you've stopped moving. Plus, it'll help you relax post-meal so you won't be tempted by stress-induced grazing that can rack up calories.
