15 Foods That Burn More Calories Than They Contain


2. Grapefruit

This sweet and sour fruit is essentially all water with a bit of roughage thrown in.

Much like celery, this fruit is about 60% or more water, and most of the rest of this fruit is healthy fiber that boosts digestive health and promotes feelings of fullness.

The particular type of fiber that is found in grapefruit is called pectin, and it doesn’t just fill you up; it also reduces arterial hardening, helping to protect your body against heart disease.

Eating plenty of grapefruit may also help to boost your metabolism, helping your body to burn more calories at a faster rate. Grapefruit slices or grapefruit juice can also boost your energy in the morning or when you hit a slump during the work day.

In addition to being a great morning snack, grapefruit is a good choice at any time of day if you want to enjoy something sweet that is still exceptionally healthy. For example, this fruit contains phytonutrients called limonoids, which may help to reduce your chances of developing tumors in the stomach, colon and lungs.

Meanwhile, people who eat the greatest quantities of red grapefruit typically have up to 16% lower levels of LDL cholesterol (i.e. ‘bad’ cholesterol).

      Oh goodness! I know you posted this comment a year ago, but it made me laugh so hard! Your humor lives on…thanks 🙂

      The twine adds even more fiber and for those not want to eat it, it takes even more energy to untie it.

      Earl Grey tea is flavored with an oil from a type of orange which contains the same substance that grapefruit does. Some soft drinks are also flavored with it. This substance interferes with many prescription medications. I love Double Bergamot Earl Grey Tea; I noticed there is no warning on the box though. I don’t know how much one has to drink to cause a problem, but I did read a post by a man who found his tea was causing a problem with his medication.

    Re: Yogurt: Fat free yogurt isn’t all it’s cracked up to be. For instance, if you’re adding it to fruit for breakfast, there are a good number of fat soluble vitamins and minerals that your body will not be able to make use of from that meal. A better option is yogurt made from 1% or 2% milk – it’s still lower in calories than the full-fat version, but the fat in it will help with absorbing those valuable micro-nutrients. Additionally, the body needs some fat to function, and the fat in cow/goat/other animal milks is a healthy form of fat in moderation.

      Actually, animal fat is good for you. In spite of all the propaganda we hear from the medical community, saturated fat does *not* cause heart disease. (Remember how they told us for 70 years that margarine was better than butter, and then they went, “Oops!!!!” 😉 ) Our ancestors knew nothing about low-fat diets and ate lots of saturated fat for thousands of years. And the reason we’re living longer today isn’t because of our diets–it’s because of better sanitation and health care, the elimination of famines, and the eradication of infectious diseases. Back then, things like cancer, Alzheimer’s, and diabetes (which are due largely to our unhealthy modern diets) were almost unheard of

      Anyway, in light of all this, the best yogurt for you is full-fat, assuming that it’s organic or comes from a local farm that allows its animals to graze and feeds them minimal grain, if any. Similarly, the best meat has plenty of fat as well, assuming it’s also raised in this manner.

        That vitamin D enriched non-fat milk is a joke. Without fat, the body cannot utilize the fat soluble vitamin D. One has to eat something fatty with the non-fat milk; so, what’s the point, right?

    great article and always tie celery with jute.(fruit torcher)

    We need fat! If it says, diet, low-fat, light, TRASH IT!

    • Katie Schultz December 20, 2014 at 6:47 am -

      We need fat, but like with many things, we need it in moderation. By all means, don’t cut out all fats (though that would be hard to do anyway) but also don’t go too heavy on the fat!

    Excuse me, but doesn’t this invalidate the laws of science?

      One word – digestion. Energy for that shit aint just gonna pop up outta nowhere.

    grapefruit should never be eaten if you take statins to control your cholesterol levels. also other drugs in combination with grapefruit may cause some unpleasant side effects. Apart from this, worth while trying. I actually already each most of the food listed and keep fit and trim

    • sf_jeff March 29, 2015 at 4:26 am -

      If you are taking statins for cholesterol, you should also be eating fiber, whole grains, and nuts. It is likely that nuts provide as much cholesterol protection as statin drugs, but they don’t have a huge advertising machine behind them.

    The idea that there are negative calorie foods—foods that are so low in calories that simply digesting them burns more calories than they contain—is nothing more than wishful thinking. Certain low-calorie, water-rich foods like celery or cucumbers are often touted as negative-calorie foods. However, digesting and absorbing everything you eat each day uses just 10% of your total calorie intake each day (about180 calories for someone who eats 1,800 calories per day). It is great to include low-calorie, high-fiber, and water-rich foods in your daily diet; these foods add nutrients, bulk, and volume to your diet and can help keep you full … but they still contain calories and should always be included in your calorie count. NOTHING in life is ‘free … and no food is a “free” food. Eating too much of any food can cause weight gain or inhibit weight loss.

      You use energy to get food into your body, more to chew it and transport it through your gut, some more to produce the chemicals to digest it, more to absorb it, more to transport it around your body and more to process it. The chemical energy you get from some food is not enough to cover the energy cost. Celery is one of these foods. Quite simple really. If you want to test this out try living on celery. You will slowly starve.

    Yeah it’s very hard to mix these without knowing exactly what are the side effects. If there are …

    I’ve heard that apricots have negative calories, but is the same for dried apricots? I’ve asked more people than I can count and they’ve given me lectures so can you please answer yes or no I’d really apreciate it thank you.
