10 Ways to Eat for Abs

What foods support loss of belly fat, or help keep off the weight? Come along with me, and let's take a look! My name is Annette Snyder, and I've been a registered dietitian (RD) for nearly 20 years, now working with Top Nutrition Coaching. I've had extensive experience in the practice areas of weight management, diabetes care, and digestive disorders. I currently maintain additional board certification (CSOWM) in weight management through the Commission on Dietetic Registration, the credentialing body for the Academy of Nutrition and Dietetics. I'm passionate about the new things nutrition science is teaching us. My goal is sharing that knowledge in a way that inspires others to get curious about their health. The foods that support intended weight loss share some qualities in common (1-3). They tend to be higher in fiber, contain a decent amount of protein, and fewer inflammatory fats (saturated). Read on for my list of 10 ways to eat for abs.

This is a no-brainer. A number of scientific studies (4) have suggested links to eating more produce, especially veggies, with lower risk of gaining weight and lower waist circumference. Plus, you know, you get vitamins and minerals. Bonus!

These include oats, buckwheat, quinoa, barley and others. While they're full of gut-friendly fiber, vitamins, minerals, and antioxidants, they also help manage blood sugar. Keeping your blood sugar in check means you deal with fewer mid-afternoon cravings (5) for all things carb. Whole grains have also been associated with appetite control and can affect how the body uses energy (calories) from food (6).

Heart-healthy fats from fish (like tuna, mackerel, salmon), in addition to calming inflammation in the body, have a role in weight control by promoting lower belly fat and unhealthy triglyceride levels (blood fats) (7). Fish is also a rich protein source, which is important in maintaining muscle mass. Protein has been linked to reduced appetite (8) along with fiber.

Not to be outdone in the nutrient department, nuts and seeds provide boosts of fiber, protein, and healthy fats. Various smaller studies have observed reductions in belly fat and/or waist circumference when consuming almonds (9) or chia (10), for example. There are tons of options—pumpkin seeds, sunflower seeds, walnuts, pistachios, just to name a few—and they're great for snacking!

Green tea has also entered the conversation. It contains the compound EGCG, which has been observed to bump up your calorie burn (11). Various studies have also found loss of belly fat and waist circumference with regular intake of green tea (12). Aside from EGCG, green tea is loaded with antioxidants.

What about the bacteria in our digestive tract? They play a role, too! More studies in recent years (13) have identified the role of our microbiome in appetite as well as metabolism. At present, we continue to investigate what those microbes are doing that has those effects. Various strains such as Lactobacillus and Bifidobacterium have been looked at (14) more closely for a possible link in weight loss—stay tuned. In the meantime, keep your gut happy with some probiotics from food: kefir, yogurt, kimchi, sauerkraut, and aged cheeses are some great sources.

How about your hydration? Do you drink enough fluid (especially water) on a daily basis? Your body uses water in its day-to-day function to perform tasks like burning calories. It's kind of like the oil that makes the machine work better. A study on hydration and health in older adults (15) found a strong link between low fluid intake/dehydration and increased occurrences of weight gain, high waist circumference, insulin resistance, diabetes, low HDL (good) cholesterol, high blood pressure, and metabolic syndrome. Drink up!

Aside from what we eat and drink (or don't), how we eat can have a big impact. Are you known for finishing your meal well before everyone else at the table? (Do you taste your food?) Take a pause. Slowing down actually lets your body do its thing and send you the message that you have taken in enough fuel (calories). You cruise right on by that point and don't hear the message when you rush the process—resulting in eating more calories than you actually need. 

Of course, I'm going there: we tend to eat too much added sugar. Added sugar (vs naturally-occurring sugar in things like fruit or milk) has number of drawbacks. Added sugars don't add nutrition. Our bodies aren't set up to process the large quantities we are capable of ingesting, and figuring out what to do with that extra fuel is where we see fat storage start. A large review of the available studies aimed to determine what happens with excess sugar intake (16), and it ain't pretty. Significant links between sugar intake and higher weight, along with a host of other conditions such as heart disease and depression, have been suggested. Sugar-sweetened drinks are the biggest culprit: soda, fruit drinks, sweet tea, and coffee drinks. (As a coffee lover myself, that last one hits hard.)

Alcohol has been linked to belly fat for quite some time now. Various studies have found links between drinking and increased waist circumference (17), especially if consuming in larger quantities (18). Calories from alcohol are not stored like carbohydrates (19) (glycogen); rather the body stores them as fat. Essentially, alcohol offers calories, just like added sugars, and no nutrition benefit. 

While a number of foods can provide benefits that support weight loss, it's important to remember that you don't eat in a vacuum. What do I mean? Eating more almonds while living on fast food isn't going to do the job. Get your house in order with all of your food and drink choices to see real results.
