Your weight is largely controlled by hormones. Research shows that hormones influence your appetite and how much fat you store.
Here are 9 ways to “fix” the hormones that control your weight.
Insulin is a hormone produced by the beta cells of your pancreas. It’s secreted in small amounts throughout the day and in larger amounts after meals. Insulin allows your cells to take in blood sugar for energy or storage, depending on what is needed at the time.
Insulin is also the main fat storage hormone in the body. It tells fat cells to store fat, and prevents stored fat from being broken down. When cells are insulin resistant (very common), both blood sugar and insulin levels go up significantly.
Chronically elevated insulin levels (termed hyperinsulinemia) can lead to many health problems, including obesity and metabolic syndrome
Overeating — especially sugar, refined carbohydrates, and fast food — drives insulin resistance and increases insulin levels
Here are some tips to normalize insulin levels and improve insulin sensitivity:
Avoid or minimize sugar: High amounts of fructose and sucrose promote insulin resistance and raise insulin levels
Reduce carbohydrates: A low-carb diet can cause an immediate drop in insulin levels.
Fill up on protein: Protein actually raises insulin in the short-term. However, it should lead to long-term reductions in insulin resistance by helping you lose belly fat
Include plenty of healthy fats: Omega-3 fats found in fatty fish can help lower fasting insulin levels
Exercise regularly: Overweight women who walked briskly or jogged had an improvement in insulin sensitivity after 14 weeks in one study
Get enough magnesium: Insulin resistant people are often low in magnesium, andmagnesium supplements can improve insulin sensitivity.
Drink green tea: Green tea may lower blood sugar and insulin levels.
Bottom Line: Insulin is the main fat storage hormone in the body. Reducing sugar intake, cutting carbs and exercise are the best ways to lower insulin levels.
Leptin is produced by your fat cells. It’s considered a “satiety hormone” that reduces appetite and makes you feel full. As a signaling hormone, its role is to communicate with the hypothalamus, the portion of your brain that regulates appetite and food intake.
Leptin tells the brain that there’s enough fat in storage and no more is needed, which helps prevent overeating.
People who are overweight or obese usually have very high levels of leptin in their blood. In fact, one study found that leptin levels in obese people were 4 times higher than in people of normal weight.
If leptin reduces appetite, then obese people with high levels of leptin should start eating less and lose weight.
Unfortunately, in obesity the leptin system doesn’t work as it should. This is referred to asleptin resistance.
When leptin signaling is impaired, the message to stop eating doesn’t get through to the brain, so it doesn’t realize you have enough energy stored
In essence, your brain thinks it is starving, so you’re driven to eat.
Leptin levels are also reduced when you lose weight, which is one of the main reasons it is so hard to maintain weight loss in the long-term. The brain thinks you are starving, and pushes you to eat more in order to produce more leptin.
Two potential causes of leptin resistance are chronically elevated insulin levels and inflammation in the hypothalamus.
Here are a few suggestions for improving leptin sensitivity:
Avoid inflammatory foods: Limit foods that cause inflammation, especially sugary drinks and trans fats.
Eat certain foods: Eat more anti-inflammatory foods, such as fatty fish.
Exercise regularly: Moderate activity can improve leptin sensitivity.
Get enough sleep: Studies have shown that insufficient sleep leads to a drop in leptin levels and increased appetite.
Supplements: In one study, women on a weight-loss diet who took alpha-lipoic acid and fish oil lost more weight and had a smaller decrease in leptin than those in a control group.
Bottom Line: People with obesity tend to be resistant to the effects of leptin. Consuming anti-inflammatory foods, exercising and getting enough sleep may improve leptin sensitivity.
Ghrelin is known as a “hunger hormone.”
When your stomach is empty, it releases ghrelin, which sends a message to the hypothalamus telling you to eat.
Normally, ghrelin levels are highest before eating and lowest about an hour after you’ve had a meal.
However, in overweight and obese people, fasting ghrelin levels are often lower than in people of normal weight.
Studies have also shown that after obese people eat a meal, ghrelin only decreases slightly. Because of this, the hypothalamus doesn’t receive as strong of a signal to stop eating, which can lead to overeating.
Here are a few tips to reduce ghrelin levels:
Sugar: Avoid high-fructose corn syrup and sugar-sweetened drinks, which can impair ghrelin response after meals.
Protein: Eating protein at every meal, especially breakfast, can reduce ghrelin levels and promote satiety.
Bottom Line: Eating plenty of protein and avoiding foods and beverages high in sugar can help reduce ghrelin levels.
