You know that light yellow color that makes margarine look almost indistinguishable from butter when laid side by side? Well, it’s far from natural. In fact, without all the additives, margarine is actually an appetite-crushing shade of grey—yuck! As if that weren’t bad enough, many brands add propylene glycol, a synthetic compound, to their recipe to add grease without adding calories. Research has shown that the spread may expand your waistline, increase dangerous cholesterol levels and up your heart disease risk. Instead of margarine, we suggest one of these 8 Best Fats for Weight Loss.
MUFAs, or monounsaturated fatty acids, are the cornerstone of the Flat Belly Plan. These are plant-based fats, so the easiest way to remember them is to look for healthy fats that aren’t from animal sources, such as avocados, nuts, seeds, oils and olives. A study done through the American Diabetic Association found that a diet rich in MUFAs worked to reduce belly fat.
Another imbalance that plagues the abs is between the obliques, the muscles that cinch your sides. You have two sets on both your right and left, and if you show them love, they'll give you a nice hourglass shape. Sadly, your left obliques start out at a disadvantage, says Hahn. Blame your heart, which takes up extra space and makes the obliques difficult to tone—an issue that's compounded if you're right-handed. "Think about where your mouse pad is," says Hahn. "Then you shake hands, change the radio station in the car—you do so much with your right side, making it stronger."

The best part? Instead of cranking out dozens of crunches, we’re about to make-under your ab routine. For the first two weeks, do two to three circuits of the first four moves; together they hit all four ab muscle groups. “You’ll reach your goal faster if your workout builds on intensity and total reps done over time,” Olson explains. These moves get a little harder and the reps get higher for week three, plus there’s an exercise added in. Same for week four, except this time you’ll add two more moves to your session. By that week, expect two to three circuits of seven moves with the max challenge and reps. No sweat—you’ll be ready.
Plank: Start on your hands and knees and come up into a push-up plank position, balancing on hands (or elbows) and toes (or knees). Align wrists under shoulders; keep your back straight and the abs and glutes tight (to keep the back from sagging). Hold the position and breathe out for 10 seconds, exhaling to tighten the abs and draw the navel to the spine.
Your core is the center of your body. You need to identify it, engage it and have all movements extend from it. It's also key to go beyond basic crunches. They're one-dimensional, hitting only the rectus abdominis (or six-pack). My quickie series targets the midsection from multiple angles, part of the reason why my clients over 40, like J.Lo, still have sculpted abs. Pair with 30 to 60 minutes of cardio and aim to do it six times a week.

Squat-thrust push-ups. Start in push-up position, do one push-up, then push off with your feet and pull your knees up to your chest so your feet land between your hands (still on the ground in push-up position), then jump as high as you can, arms over head. Squat back down with your hands on the floor, then jump back to push-up position again. Do as many as you can do well with good form.

Cruciferous veggies are one of the healthiest vegetables you can eat, but unfortunately they're also the ones most likely to cause your tummy to inflate. Thanks to raffinose, a compound that produces extra gas as it breaks down, broccoli, cabbage, cauliflower and the like can seriously increase your waistline. But don't ditch them forever. Just save them for meals where you can wear loose pants. Here are other surprising foods that cause gas.
It’s not just about weight loss. Having great gut health is linked to good health throughout your body. Scientists in this rapidly growing field are finding connections between gut microbes and the  immune system, weight loss, gastrointestinal health, , allergies, asthma, and even cancer. With every study that’s published, scientists become more convinced that having a healthy gut leads to having a healthy body.
