There is a lot of weight loss advice on the internet.

Most of it is either unproven or proven not to work.

Here are the top 12 biggest lies, myths, and misconceptions about weight loss.

The calorie is a measurement of energy. All <a dir="ltr" href="https://www.healthline.com/nutrition/how-many-calories-per-day">calories </a>have the same energy content.

However, this does not mean that all calorie sources have the same effects on your weight.

Different foods go through different metabolic pathways and can have vastly different effects on hunger and the hormones that regulate your body weight.

For example, a protein calorie is not the same as a fat or carb calorie.

Replacing carbs and fat <a dir="ltr" href="https://www.healthline.com/nutrition/how-protein-can-help-you-lose-weight">with protein </a>can boost your metabolism and reduce appetite and cravings, all while optimizing the function of some weight-regulating hormones (<hl-trusted-source dir="ltr" rationale="Highly respected database from the National Institutes of Health" source="PubMed Central"><a dir="ltr" href="https://www.ncbi.nlm.nih.gov/pubmed/25926512" rel="noopener noreferrer">1 </a> </hl-trusted-source>

Also, calories from whole foods like <a dir="ltr" href="https://www.healthline.com/nutrition/is-fruit-good-or-bad-for-your-health">fruit </a>tend to be much more filling than calories from refined foods, such as candy.

Losing weight is usually not a linear process, as some people think.

Some days and weeks you may lose weight, while during others you may gain a little bit.

This is not a cause for concern. It’s normal for body weight to fluctuate up and down by a few pounds.

For example, you may be carrying more food in your <a dir="ltr" href="https://www.healthline.com/nutrition/best-foods-for-digestion">digestive system </a>or holding on to more water than usual.

This is even more pronounced in women, as <a dir="ltr" href="https://www.healthline.com/nutrition/13-ways-to-lose-water-weight">water weight </a>can fluctuate significantly during the menstrual cycle (<hl-trusted-source dir="ltr" rationale="Highly respected database from the National Institutes of Health" source="PubMed Central"><a dir="ltr" href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3154522/" rel="noopener noreferrer">4 </a> </hl-trusted-source>

As long as the general trend is going downwards, no matter how much it fluctuates, you will still succeed in losing weight over the long term.

The weight loss supplement industry is massive.

Various companies claim that their supplements have dramatic effects, but they’re rarely very effective when studied.

The main reason that supplements work for some people is the placebo effect. People fall for the marketing tactics and want the supplements to help them lose weight, so they become <a dir="ltr" href="https://www.healthline.com/nutrition/mindful-eating-guide">more conscious of what they eat </a>.

That said, a few supplements have a modest effect on weight loss. The <a dir="ltr" href="https://www.healthline.com/nutrition/12-weight-loss-pills-reviewed">best ones </a>may help you shed a small amount of weight over several months.

It is inaccurate to say that your weight is all about willpower.

Obesity is a very complex disorder with dozens — if not hundreds — of contributing factors.

Numerous genetic variables are associated with obesity, and various medical conditions, such as hypothyroidism, PCOS, and depression, can increase your risk of <a dir="ltr" href="https://www.healthline.com/nutrition/10-causes-of-weight-gain">weight gain </a>(<hl-trusted-source dir="ltr" rationale="Highly respected database from the National Institutes of Health" source="PubMed Central"><a dir="ltr" href="https://www.ncbi.nlm.nih.gov/pubmed/17566051" rel="noopener noreferrer">5 </a> </hl-trusted-source>

Your body also has numerous hormones and biological pathways that are supposed to regulate body weight. These tend to be dysfunctional in people with obesity, making it much harder to lose weight and keep it off (<hl-trusted-source dir="ltr" rationale="Highly respected journal,Expert written journal,Peer reviewed journal" source="International Journal of Obesity"><a dir="ltr" href="http://www.nature.com/ijo/journal/v39/n8/full/ijo201559a.html" rel="noopener noreferrer">6 </a> </hl-trusted-source>

For example, being resistant to the hormone <a dir="ltr" href="https://www.healthline.com/nutrition/leptin-101">leptin </a>is a major cause of obesity (<hl-trusted-source dir="ltr" rationale="Highly respected database from the National Institutes of Health" source="PubMed Central"><a dir="ltr" href="https://www.ncbi.nlm.nih.gov/pubmed/25232147" rel="noopener noreferrer">7 </a> </hl-trusted-source>

The leptin signal is supposed to tell your brain that it has enough fat stored. Yet, if you’re resistant to leptin, your brain thinks that you’re starving.

Trying to exert willpower and consciously eating less in the face of the leptin-driven starvation signal is incredibly difficult.

Of course, this doesn’t mean that people should give up and accept their genetic fate. Losing weight is still possible — it’s just much harder for some people.

Body fat is simply stored energy.

For this reason, it seems only logical that eating less and moving more would cause weight loss.

While this advice works in theory, especially if you make a permanent lifestyle change, it’s a bad recommendation for those with a serious weight problem.

Most people who follow this advice end up regaining any lost weight due to physiological and biochemical factors (<hl-trusted-source dir="ltr" rationale="Highly respected database from the National Institutes of Health" source="PubMed Central"><a dir="ltr" href="https://www.ncbi.nlm.nih.gov/pubmed/25896063" rel="noopener noreferrer">6 </a> </hl-trusted-source>

A major and sustained change in perspective and behavior is needed to lose weight with diet and <a dir="ltr" href="https://www.healthline.com/nutrition/10-benefits-of-exercise">exercise </a>. Restricting your food intake and getting more physical activity isn’t enough.

Instructing someone with obesity to simply eat less and move more is like telling someone with depression to cheer up or someone with alcoholism to drink less.

It’s true that obesity increases your risk of several chronic illnesses, including type 2 diabetes, heart disease, and some <a dir="ltr" href="https://www.healthline.com/nutrition/cancer-and-diet">cancers </a>(<hl-trusted-source dir="ltr" rationale="Highly respected database from the National Institutes of Health" source="PubMed Central"><a dir="ltr" href="https://www.ncbi.nlm.nih.gov/pubmed/12503980" rel="noopener noreferrer">18 </a> </hl-trusted-source>

However, plenty of people with obesity are metabolically healthy — and plenty of thin people have these same chronic diseases (<hl-trusted-source dir="ltr" rationale="Governmental authority" source="Centers for Disease Control and Prevention (CDC)"><a dir="ltr" href="http://www.cdc.gov/nchs/data/nhsr/nhsr013.pdf" rel="noopener noreferrer">21 </a> </hl-trusted-source>

It seems to matter where your fat builds up. If you have a lot of fat in your <a dir="ltr" href="https://www.healthline.com/nutrition/6-proven-ways-to-lose-belly-fat">abdominal area </a>, you’re at a greater risk of metabolic disease (<hl-trusted-source dir="ltr" rationale="Highly respected database from the National Institutes of Health" source="PubMed Central"><a dir="ltr" href="https://www.ncbi.nlm.nih.gov/pubmed/18220642" rel="noopener noreferrer">22 </a> </hl-trusted-source>

A lot of junk food is marketed as healthy.

Examples include low-fat, fat-free, and processed gluten-free foods, as well as <a dir="ltr" href="https://www.healthline.com/nutrition/liquid-sugar-calories">high-sugar beverages </a>.

You should be skeptical of any health claims on food packaging, especially on processed items. These <a dir="ltr" href="https://www.healthline.com/nutrition/how-to-read-food-labels">labels </a>usually exist to deceive — not inform.

Some junk food marketers will encourage you to buy their fattening junk food. In fact, if the packaging of a food tells you that it’s healthy, there’s a chance it’s the exact opposite.

Oftentimes, products marketed as diet foods are junk foods in disguise, as they’re heavily processed and may harbor hidden ingredients.

If you’re trying to <a dir="ltr" href="https://www.healthline.com/nutrition/how-to-lose-weight-as-fast-as-possible">lose weight </a>, you may have heard a lot of the same myths. You may have even believed some of them, as they’re hard to avoid in Western culture.

Notably, most of these myths are false.

Instead, the relationship between food, your body, and your weight is very complex.
