A high-fiber diet decreases fat and cholesterol absorption in your intestine (preventing fat storage), slows glucose absorption in the bloodstream (meaning more sugar gets burnt as energy, less gets stored as fat), stabilizes insulin levels and delays stomach emptying (both of which decrease your appetite), and makes you full faster (so you eat less). Research has shown that a low-fat, high-fiber diet results in nearly three times more weight loss than a low-fat, low-fiber diet. So how do you get your fiber? Here’s how I get mine: 1 fully loaded salad, 1 bowl of oatmeal, and 2-3 raw fruits every day (fruit bonus: vitamin C in citrus fruit can also help burn fat).
Research shows that three or four daily servings of low-fat dairy products can help reduce body fat. Higher levels of calcium stored in the fat cells may help enhance fat breakdown, as well as induce an increase in thermogenesis (the body’s core temperature). The best calcium should come from dairy products like low-fat milk, yogurt and cottage cheese (and not from a calcium supplement). Other good sources, especially for those who are lactose intolerant, include dark leafy vegetables, salmon, almonds, and oats (notice the extra fiber bonus).
Breakfast is the most important meal of the day. Studies have shown that people who include a large and healthy breakfast in their diet lose significantly greater amounts of fat than those who avoid breakfast. Skipping breakfast will not help you shed extra pounds, but may instead result in muscle loss and metabolism decreases, both of which hinder your fat-burning ability. A great breakfast example is a large glass of water with a bowl of oatmeal, fresh fruit and nuts. Just remember: breakfast can also work against you if it’s not healthy…fried meats, sweet muffins and croissants, sugar loaded cereals, or processed packages do not count as a healthy breakfast!
You’ve heard it a million times before: 5-6 small meals a day is better than 3 large meals. I’d like to step that up a bit: as high as 10 times a day or more may be necessary, depending on your energy consumption and needs. Here’s an example: 1) banana 7am; 2) oatmeal w/ raisins 9am; 3) handful almonds 10:30am; 4) three turkey slices 12pm; 5) one yogurt 1 pm; 6) apple 2pm; 7) large salad 4:30pm; 8) one protein bar 7:00pm; 9) handful raisins 8:15pm; 10) 1 scramble egg with spinach 9pm (bed at 11pm). The philosophy behind eating frequently is that the physical act of digestion has a metabolic cost, and by continually feeding, you are maintaining a higher metabolic rate. As long as your grazing is healthy, this results in more calories burnt throughout the day. On the flipside, eating too infrequently causes your body go into starvation mode and conserve energy, which results in increased fat storage and lower digestive and overall metabolism.
Your body constantly uses water to create energy, build muscle, and burn fat, and without adequate water, studies have shown that the muscles are less active, the metabolism drops, and your body burns fat less efficiently. This slight decrease in metabolism can add up to over 10 pounds of fat a year! Water also assists in suppressing the appetite and giving you a “full feeling”. So drink several glasses of water each day, drink a glass of water at least 30 minutes before your workout, sip water regularly at the gym, and drink a glass of water after your workout (speeds up recovery too!). Many naturally occurring foods, such as fruits and vegetables, are also high in water content (as well as fiber, vitamins, minerals, phytonutrients, etc.), so this is another great way to get your H2O.
Meals that contain larger amounts of carbohydrates should be eaten earlier in the day. This means that much of your whole grain and fruit consumption should occur before noon. The body's metabolism is highest earlier in the day, so this is a great time to be supplying your muscles with energy in the form of glycogen (carbohydrates), while also ensuring that many of the carbohydrates you consume will be burned for fuel, rather than deposited as fat stores. Many families tend to have the biggest meal of the day in the evening, ironically at the time when the body is least in need of energy and the metablim is lowest. The practical application would be to make breakfast bigger and dinner smaller. So try it out - prioritize eating carbohydrates early in the day, and focus on decreasing carbohydrate portion size as afternoon and evening approaches.
While carbohydrates are important for providing energy and giving your body the ability to burn fat, you must choose the right carbs. Simple carbs like sugar and processed flour tend to be rapidly absorbed by the digestive system, which causes a release of the hormone that encourages fat deposit - insulin. Furthermore, the quick energy release that is followed by a rapid decrease in sugar levels will cause you to crave more food. So no matter what percentage of your diet is made up of carbohydrates, you must choose complex carbs that are slowly absorbed and digested, thus producing a long term source of energy that keeps you fuller for a longer period of time. Whole grain flours, vegetables, oats, and unprocessed grains, such as brown or wild rice are great choices, and also include many other compounds important in maintaining a high metabolism and proper digestive function.
To replace calories that are not provided by dietary fat, carbohydrate consumption increases. Increased carb consumption leads to a faster burning energy source, which tends to contribute to cycling blood sugar levels, use of muscle tissue as fuel, low energy, and decreased metabolism and hormone production. In addition, many Americans will replace saturated fat, such as butter, with a trans fat, such as margarine. Trans fats are *much* worse for the body than saturated fat. So it is important to choose the right kinds of fat. Most animal fats, and many vegetable oils, are high in cholesterol, which contributes to heart disease. However, mono-unsaturated fats, such as those found in olive oil, nuts, fish oil, and various seed oils, can help lower cholesterol, reduce risk of heart disease, and enhance your body's ability to burn fat as a fuel source. So try to eat fish several times a week (or supplement with fish oil), cook with olive oil, and try to eat at least a handful of a healthy nut (like almonds or walnuts) once per day.
Artificial sweeteners, such as Aspartame, still taste sweet (that's why they're sugar replacements!). When the taste receptors on your tongue taste this sweet substance, your digestive systems begins to produce compounds that prepare your body to use the food that your brain thinks you are consuming. The hormones produced in the digestive process are still present once this fake food enters your small intestine, but no actually energy release or satiety occurs, which leaves you with a gut full of digestive hormones that need food to break down and make the brain crave even more food, this time the real stuff. This is why studies have shown that consumption of diet soda products are associated with obesity! If you're really serious about burning fat, ditch any sugar substitute foods or diet drinks that you currently consume. I guarantee that once you overcome the initial addiction withdrawal, you'll feel a hundred times better.
Your body runs on fuel. If you put too much fuel into the gas tank, an overflow occurs, and in the body's case, this means fat deposition. I realize that the idea of limiting calories is very simple, but sometimes the approach is wrong. Never give yourself a certain number of calories per day. You'd never take your car to the gas station and fill up if you didn't plan on driving it, and the same goes for your body. If you have a light day of activity (low mileage) or a sedentary day (sitting in the garage), you should sometimes not even be consuming 50% of the calories you'd normally consume, because your body doesn't need them. For instance, on a typical day, consume 5000-6000 calories (based on metabolism and amount of activity), but on a weekend of travel, where either sitting in a car or airplane, often consume as little as 1000 calories per day! If your body doesn't need the fuel, there's not a necessity to put it in your mouth. On the other hand, there will be some days where consume up to 8000 calories, simply because that is how many actually burn through activities! So if you're on a set diet of, say, 2000 calories per day, don't be afraid to vary as needed.
