Healthy Foods

Just this past week, I posted an article on the 3 best exercise to lose fat. What better follow-up article to that than one on the 3 best food to lose fat? As mentioned in the outset of that article, exercise is one piece of the foundation for fat loss. And my guess is that if you’re reading this article right now, you know what the another piece of that foundation is. That’s right, our food intake and nutrition plays a major role in our journey to losing that stubborn fat.

The same way that certain exercises are touted as the best fat burner of the decade or the long lost exercises practiced by the fi

ttest people that ever lived, certain foods are given similar praise by fitness “gurus” and “experts”. Compared to exercise however, nutrition has much more conflicting information and opinions in the fitness industry. I’ve mentioned this briefly on my articles on Recommended Meal Frequencies Part 1 and Part 2. This can be quite troublesome since we’re interested in the facts and in this case, the best foods that work for us in losing fat.

Following in the same footsteps of all my posts, this is another no fluff, straight to the point article based on scientific studies and facts. This should help us see through a lot of the misinformation and confusion that exists in the fitness world and distinguish between the real information and marketing scams.

3 Best Foods To Lose Fat


1. Avocados

The avocado has long been recognized for it’s nutrients, monounsaturated fats, phytochemicals, and its general versatility when it comes to making recipes. Most famous for being a center ingredient in guacamole and other dips, it can also be used for spread, ice cream, or just sliced to compliment the main dish.

Although there are different types of avocados, we’ll be discussing the Haas avocado since it’s the most common and readily available.

So what makes this fruit the #1 food for burning fat?

Nutrients

There are multiple factors that attributes to avocado taking the #1 spot in its ability to help us lose fat. As mentioned, it packs a huge punch in nutrition. Just to list some of the nutrients in a single avocado¹:

  • Vitamin C: 20.1 mg (33% of Recommended Daily Value)
  • Vitamin K: 42.2 mcg (53 % of RDV)
  • Folate: 163 mcg (41% of RDV)
  • Dietary Fiber: 13.5 g (54% of RDV)
  • Potassium: 975 mg (28% of RDV)

In addition to these vitamins and minerals, most of the fat content of avocados are that of monounsaturated fats (MUFAs). According to the American Heart Association, when compared to a diet high in carbohydrates, a diet high in MUFAs is more effective in reducing belly fat². In addition, a study done on the effects on MUFA and belly fat shows a direct correlationavocado-1287100_640 in the moderate intake of MUFAs and the reduction of belly fat³.

Although the topic of interest here is finding the best foods for losing fat, it’s worth noting that the nutrients mentioned before improves a variety of biomarkers as well, including4:

  • Lower cholesterol
  • Promote normal blood pressure
  • Help oxidative/inflammatory stress
  • Increase the bioavailability (how much becomes available for absorption) of carotenoid

All these factors attributes to vibrant health overall and keeps our bodies functioning the way it’s supposed to. So in addition to MUFAs that help us directly burn fat, all these other benefits that may not directly cause us to burn fat attributes to a healthier body, which allows the fat burning to take place as efficiently as possible.

Satiety

When it comes to losing fat, the importance of satiety of our foods cannot be overstated. Having something to keep us feeling satisfied for longer periods of time will obviously cut down on the inclination to snack or eat through out the day. The calories from those snacks can definitely add up, especially when they’re small but frequent, because c’mon, who’s really keeping count?

So how does the avocado rate on the scale for satiety? At this point, we’ve established that avocados are very high in fats. Matter of fact, an avocado is mostly fat out of all 3 macronutrients (it’s mostly water by content). This fact is why some recommend limiting our consumption of avocados. Although it should be taken in moderation, the whole “fats make you fat” myth is starting to get exposed even within the public community. That’s a topic of another article. Back to the fat avocados, I mean the fats in avocados.

According to The American Journal of Clinical Nutrition, a study performed involving young men ages 19 to 24 years old showed that the intake of dietary fat delayed hunger in the participants5. The participants were deprived of any time cues so they simply ate their second meal when they felt hungry.

This study also showed that energy intake was delayed in the group with the high dietary fat intake. This means that compared to a high carbohydrate meal, a high fat meal will provide you with energy throughout a longer period of time instead of all at food-44629_640once. Bye-bye to post lunch crashes!

A review performed on recent studies reaffirms the conclusions from the study stated above. It also notes that the type of dietary fats consumed plays a role in the level of satiety. It also states that certain genetic factors may cause some of us to have a lower tolerance for high fat foods6. This could explain why some individuals eating plenty of healthy fats cannot lose their stubborn belly fat even when they’re doing everything else right.

This review goes on to conclude that foods high in fats are typically more palatable, which would increase the chances of frequent eating and in large amounts. Although I’ve said before that the “calorie in = calorie out” concept is not true (will be explained in a later post, I promise!), the idea of taking in more calories just because a certain food is tasty is not going to help us lose fat.

However, if we consider the high fat foods that are most prevalent today, it’s obvious why the case can be made regarding the palatability of high fat foods. Most high fat foods people think of comes in the form burgers, french fries, pastries, hot dogs, all of which are available at you favorite fast food restaurant. It’s no wonder why increase eating frequency and calorie consumption would be a concern with high fat foods!

#1, Deservedly So

Yes, the avocado is really that awesome in helping us lose fat. It obviously doesn’t belong in the fatty junk food category, and the benefits range from cardiovascular disease reduction to cancer risk reduction to what we’ve been talking about, fat reduction. As mentioned before, avocados also releases energy slowly into our system so we get a steady supply of energy over time, which reduces our need to eat for more energy. It also promotes healthy bodies with its many nutrients and minerals, improving our bodily functions, which equals better fat burning efficiency.

The fact that it is a food that’s readily available in most places, provides substantial satiety, and helps us lose fat both directly and indirectly as mentioned above puts this fruit in the #1 spot on this list.

2. Kelp

Not as common as the avocado in parts of the western hemisphere, kelp is an exotic vegetable to some and a common dish to others. Kelp by definition is seaweed or sea algae that are much larger in size than your typical feet-grabbing-leg-tangling seaweed from the beach. It is generally farmed and harvested for use in supplements, medical supply of iodine, and food.

At a glance, it’s a very simple vegetable with nothing much to its appearance. But the power of kelp in improving fat loss lies in its one key ingredient, iodine.

The Power of Iodine

If we browse the supplement section of any supermarket or health food store, we’re bound to find an iodine supplement or ten. A quick look at the ingredients will show us the common ingredient in all of them include kelp or another form of sea vegetable. This is because kelp is a very rich source of iodine.seaweed-1129226_640

As of 2007, the World Health Organization reported that over 2 billion people globally are deficient in iodine7. If left unchecked, iodine deficiency leads to a very bad problem that spells trouble for fat loss.

A study was conducted on the effect of iodine supplementation on individuals with iodine deficiency but are otherwise healthy. Two groups participated in this study, with one group given a low dose while the other had a high dose. The study last 4 weeks and pre and post-study parameters were taken at the beginning, end, and 2 weeks after supplementation. All of the parameters tested for were hormones that are indicative of thyroid function. Before we get into the results, let’s see why thyroid function is of interest to us.

The Role of Thyroid

Simply put, the thyroid takes iodine that we’ve absorbed and converts them into different hormones. These hormones are released into the blood and enter each of our cells, regulating metabolism of calories and oxygen into energy. Those hormones rarely even stay at a constant level for long. If they drop too low, our pituitary gland signals the thyroid to produce more. When the levels are back to the optimal range, the thyroid down-regulates the production8.

One can see the problem with iodine deficiency not only affects our ability to burn fat, but also our health in general. If the thyroid hormones drop too low due to an iodine deficiency, the pituitary gland can signal all it wants, but the thyroid can only do so much with limited iodine. This not only stresses our thyroid, but also the pituitary gland. And a stressed pituitary gland causes a whole host of physical and mental health problems.

We can see why these thyroid hormones are so important. Just purely from a fat loss perspective, these hormones are what tells us to burn calories for fuel. And these hormones can only be produced and maintained within the optimal ranges with sufficient iodine intake.

Results

Three thyroid hormones were examined throughout this study. The study showed that both low and high dosage groups experienced no change for one of the hormones, and an increase throughout the study for another one of the hormones. The third hormone only increased for the high dosage group. However, 2 weeks after the end of supplementation, the hormone levels were analyzed again and while they returned to baseline for the low dosage group, the high dosage group had levels lower than baseline9!

While the study concluded that further tests are required to determine the long term viability of iodine supplementation for lower the risk of thyroid disease, I think a few insights can be gained from this.

  1. Iodine supplementation can definitely help those with a thyroid problem due to iodine deficiency
  2. Both high and low dosage of iodine can help produce thyroid hormones in the short term
  3. Sustained high dosages of iodine can lead to drop of thyroid hormones after stopping supplementation
  4. Possible tapering high dosage to low would be a solution to avoiding hormone level drops (just speculating)

More studies will need to be conducted to test the long-term effectiveness of iodine supplementation. But there is a question that we need to ask…

Why Supplement In Place Of Food?

This very simple question has an equally simple answer.

Appeal Does NOT Equal Nutrition
Appeal Does NOT Equal Nutrition

We shouldn’t.

It doesn’t make any sense to take something that we can get from a food source, especially when that food source is full of other nutrients as well.

Kelp is a great addition to any meal and can be cooked in a variety of ways. I’ll leave it up to you on how to prepare it for cooking but it is a must for optimal fat burning in my opinion. As one of the few food sources that provides what our thyroid needs to regulate our metabolism, this sea vegetables sits rightfully at our #2 spot on the list.

3. Green Leafy Vegetables

Last but not least, the last food is actually a category of food, although I will make a few recommendations. I believe that I don’t need to go into details on the benefits of green leafy vegetables. It is one of the few things that the fitness industry has right. Foods in this category should be a stable in our diet if we’re serious about losing fat.

Besides all the nutrients and fiber in this food group, there is at least one other way that this food group helps us lose fat.

A study performed on 38 women showed that the intake of green-plant membrane supplementation for 3 months promoted weight loss10. In addition, the overall cholesterol were lowered, and the urge for sweet and fat palatable food were both lowered as well (so much for the fatty palatable food dilemma from before).

Out of this food group, there are two specific vegetables that I highly recommend including in your diet: kale and spinach. Both are very nutrient dense and full of fiber. Both have the effect of suppressing appetite and lowering urge for palatable foods. Most of all, both have been proven to be great for fat loss.

Between the two, I’d go with kale over spinach and here’s the reason why.

Oxalic Acid, What Is That?

Oxalic acid, or oxalate, is a substance found mostly on the surface or leafy greens and other foods. This substance is vital for the metabolism of plants, animals, and humans. However, too much of this substance can wreak havoc on our health. Studies have shown that kidney stone formation and calcium deficiency due to poor absorption can be traced to high levels of oxalates in the blood11.

Interestingly, an increase in the intake of calcium, magnesium, and fiber can offset the amount of oxalate absorbed in our intestines12. However, an ounce of prevention is worth a pound of cure, so we’re better off limiting our intake of this substance than trying to combat its absorption after ingesting it.kale-1113750_640

The reason why I prefer kale over spinach is due to the oxalate content of each. Leafy green vegetables in general have always been grouped together as having high oxalate content. But that is not the case with kale. Although spinach, rhubarb, beets, and some other vegetables have higher than recommended oxalate content, kale is definitely not one of them13.

As far as spinach goes, it seems its oxalate content is lowest in the fall season. So any spinach consumption would ideally be in the fall. Although it’s not a problem to have leafy greens year-round, just like anything else, moderation is key here.

Superfoods?

I did not mention so called superfoods because many of them are not technically something that we can should make a meal out of. The top 3 choices on this list can either be a meal all to itself or can at least make up the bulk of a dish. Superfoods like goji berries and cacao are great, but just not in the same amounts as we would have for a meal.

The 3 foods chosen for this list is also suitable regardless of the type of diet or eating habit you’re on. Whether you’re a vegetarian, vegan, raw vegan or anything in between, these foods are gluten-free and dairy-free by nature. This is another big reason why they belong on this list because unlike other great candidates such as eggs, salmon, lean meats, etc., these foods can fit in everyone’s diet no problem (unless you’re a fruitarian or refuse to include vegetables in your diet).

I hope this article has proven to be helpful to you. So what foods have you personally found to be helpful for fat loss? Please leave your comments and feedback in the comments section below!

Stay healthy,

I've just started getting serious about health and fitness around 2014. Since then I've learned the insider info on how to optimize athletic performance and healthy living through both nutrition and proper training. The most important thing I've discovered however, is the connection between the mindset of those that excel in athletics, and those that succeed in their life pursuits. I've spent the last couple years observing and drawing these connections and similarities, finally created a platform to share with you all what I've found, and how to apply them in your own life to get similar results.

  1. I understand that experts have bred a lower fat avocado that is up to twice the size of the Hass with less fat and fewer calories. I’ve not tried it yet, but it hasn’t had good reviews, with some describing it as slimey and flavourless rather than rich and creamy. Given that the fat in a normal avocado is the healthy monounsaturated type, that helps to boost satiety, it’s better to go for the real thing if you want to lose weight, adn at least enjoy it!

    1. Sarah,

      Thanks for sharing that info. I never heard of that breed. I’m never been a big fan of GMO and although some are worse than others, this low fat avocado seems to defeat the purpose of eating one. The fats are one of the things that gives it its nutritious kick and taking that away is simply down-grading this fruit. Not to mention the taste factor that you spoke of.

  2. My wife is a big believer in Kelp, nice to see someone else recommending it. I have heard a lot about avocados as well but I have never tried it. I guess I should. She also has thyroid problems and your advice about iodine is spot on. Thanks for the info.

  3. Wing,
    That was an incredibly informative article on the subject of the 3 best foods to help a person lose fat. You really provided a lot of insightful facts regarding the nutrients, vitamins, minerals and other ingredients found in avocados, kelp and green-leafy vegetables of which the latter I certainly eat especially in salads.

    Fresh fruits are in fact extremely beneficial to our bodies, although personally avocados are not among my favorites – apples, cherries, oranges and blueberries top the list.

    Too many people make the make in believing that fruit juices – often laden with sugar are a valid substitute in replacing fresh fruits. But that is wrong. Fruit juices have too many additives which take away the potency of the natural minerals and vitamins found in fresh fruit.

    Great article,Wing,
    Jeff

    1. Jeff,

      Thank you! I agree on the fresh fruits and their benefits. I don’t consume a whole lot of fresh fruits personally because my local organic farmers don’t carry much of them and organic fruits at grocery stores are a bit pricey.

      And you’re on point with the fruit juices. Best to avoid them.

      -Wing

  4. Hey Wing,
    I absolutely loved your article on the best foods to lose fat. I am always very concerned about my health and this article gave me the foods that are best for me and my nutrition. From now on I will be eating more of the foods you mentioned so I can maintain my health

  5. I love your page. I can definitely get some pointers from you. It is set up wonderfully. I love avocados. I just recently started to eat them and they are deliscious! They are packed with so many nutrients and definitely give me a boost.
