Weight loss, in the context of medicine, health, or physical fitness, refers to a reduction of the total body mass, by a mean loss of fluid, body fat (adipose tissue), or lean mass (namely bone mineral deposits, muscle, tendon, and other connective tissue)
Abnormal weight loss
The weight loss does not come about because of diet, exercise or lifestyle changes. Weight loss of 10 pounds or more, or five percent of body weight, over a period of 6 to 12 months is considered “unexplained.” Unexplained weight loss can be a symptom of a serious condition or illness
10 Weight-Loss-Friendly Foods
1. Boiled Potatoes
White potatoes seem to have fallen out of favor for some reason.
However, they have several properties that make them a perfect food both for weight loss and optimal health.
They contain an incredibly diverse range of nutrients a little bit of almost everything you need.
There have even been accounts of people living on nothing but potatoes alone for extended periods of time.
They’re particularly high in potassium, a nutrient that most people don’t get enough of and that plays an important role in blood pressure control.
On a scale called the Satiety Index, which measures how filling different foods are, white, boiled potatoes scored the highest of all the foods tested.
What this means is that by eating white, boiled potatoes, you will naturally feel full and eat less of other foods.
If you allow potatoes to cool for a while after boiling, they will form high amounts of resistant starch, a fiber-like substance that has been shown to have various health benefits, including weight loss.
Sweet potatoes, turnips and other root vegetables are also excellent.
Tuna is another low-calorie, high-protein food.
It’s lean fish, meaning it’s low in fat.
Tuna is popular among bodybuilders and fitness models who’re on a cut, as it’s a great way to increase protein intake while keeping total calories and fat low.
If you’re trying to emphasize protein intake, make sure to choose tuna canned in water, not oil.
3. Beans and Legumes
Some beans and other legumes can be beneficial for weight loss.
This includes lentils, black beans, kidney beans and some others.
These foods tend to be high in protein and fiber, which are two nutrients that have been shown to lead to satiety.
They also tend to contain some resistant starch.
The main problem is that a lot of people have difficulties tolerating legumes. For this reason, it’s important to prepare them properly.
As mentioned above, meals and diets with a low energy density tend to make people eat fewer calories.
Most foods with a low energy density are those that contain lots of water, such as vegetables and fruits.
But you can also just add water to your food, making a soup.
Some studies have shown that eating the exact same food turned into a soup rather than as solid food, makes people feel more satiated and eat significantly fewer calories.
Just make sure not to add too much fat to your soup, such as cream or coconut milk, as this can significantly increase its calorie content.
Avocados are a unique fruit.
While most fruits are high in carbs, avocados are loaded with healthy fats.
They’re particularly high in monounsaturated oleic acid, the same type of fat found in olive oil.
Despite being mostly fat, avocados also contain a lot of water and fiber, making them less energy-dense than you may think.
What’s more, they’re a perfect addition to vegetable salads, Their fat content can increase carotenoid antioxidant absorption from the vegetables 2.6- to 15-fold.
They also contain many important nutrients, including fiber and potassium.
6. Apple Cider Vinegar
Apple cider vinegar is incredibly popular in the natural health community.
It’s often used in condiments like dressings or vinaigrettes, and some people even dilute it in water and drink it.
Several human-based studies suggest that apple cider vinegar can be useful for weight loss.
Taking vinegar at the same time as a high-carb meal can increase feelings of fullness and make people eat 200–275 fewer calories for the rest of the day.
One 12-week study in obese individuals also showed that 15 or 30 ml of vinegar per day caused weight loss of 2.6–3.7 pounds, or 1.2–1.7 kilograms.
Vinegar has also been shown to reduce blood sugar spikes after meals, which may have various beneficial health effects in the long term.
Despite being high in fat, nuts are not as fattening as you would expect.
They’re an excellent snack, containing balanced amounts of protein, fiber and healthy fats.
Studies have shown that eating nuts can improve metabolic health and even promote weight loss.
What’s more, population studies have shown that people who eat nuts tend to be healthier and leaner than those who don’t.
Just make sure not to go overboard, as they’re still fairly high in calories. If you tend to binge and eat massive amounts of nuts, it may be best to avoid them.
8. Chili Pepper
Eating chili peppers may be useful on a weight loss diet.
They contain capsaicin, a substance which has been shown to reduce appetite and increase fat burning in some studies.
This substance is even sold in supplement form and a common ingredient in many commercial weight loss supplements.
One study showed that eating 1 gram of red chili pepper reduced appetite and increased fat burning in people who didn’t regularly eat peppers.
However, there was no effect in people who were accustomed to eating spicy food, indicating that a certain level of tolerance can build up.
One fruit that deserves to be highlighted is grapefruit. Its effects on weight control have been studied directly.
In a 12-week study in 91 obese individuals, eating half a fresh grapefruit before meals led to weight loss of 3.5 pounds (1.6 kg).
The grapefruit group also had reduced insulin resistance, a metabolic abnormality that is implicated in various chronic diseases.
Therefore, eating half a grapefruit about half an hour before some of your daily meals may help you feel more satiated and eat fewer overall calories.
10. Coconut Oil
Coconut oil is high in fatty acids of a medium length, called medium-chain triglycerides (MCTs).
These fatty acids have been shown to boost satiety better than other fats and increase the number of calories burned.
What’s more, two studies — one in women and the other in men — showed that coconut oil reduced amounts of belly fat.
Of course, coconut oil still contains calories, so adding it on top of what you’re already eating is a bad idea.
It’s not about adding coconut oil to your diet but about replacing some of your other cooking fats with coconut oil.
However, studies show that coconut oil is less satiating than MCT oil — a supplement that contains much higher numbers of medium-chain triglycerides.
