Bella FAQs

The Plan
What does Bella+ do?

Bella+ is a combination of six medications that modulate appetite and reduce cravings. Each of these medications has been shown to have weight loss benefits alone and in combination with other medications.

  • Bupropion and Naltrexone: These two medications work together in the brain to reduce hunger and cravings. They block the feedback loop that makes high-calorie, high-fat foods so irresistible.
  • Oxytocin: In addition to reducing anxiety, oxytocin decreases caloric intake, increases fat breakdown, and improves insulin sensitivity.
  • Metformin: Metformin is a first-line medication used to control blood sugar in type 2 diabetes. It also modulates appetite and improves insulin resistance.
  • Topiramate: A side effect of topiramate (an anti-seizure medication) is weight loss, which led researchers to test its ability to control blood sugar and support weight loss in clinical trials.
  • Vitamin B12: Vitamin B12 helps fight fatigue, boost energy, and support weight loss efforts. Low vitamin B12 levels have been linked to overweight and obesity.
Which is better for weight loss, topiramate or metformin?

Both topiramate and metformin help people lose weight.

Antipsychotic medications frequently cause weight gain, diabetes, high cholesterol levels, and cardiovascular issues. Researchers tested both topiramate and metformin to see if they would help mitigate these side effects.

Both topiramate and metformin were rated as effective treatment options that patients tolerated well.

What does metformin do to your body?

Metformin is a first-line treatment option for type 2 diabetes. It decreases sugar absorption from the gastrointestinal tract and decreases the production of sugar in the liver. Metformin also makes the body more sensitive to insulin. Metformin lowers blood glucose by about 25% to 30%, with a low risk for hypoglycemia.

Metformin may cause weight loss by:

  • Decreasing liver glucose production
  • Altering the gut microbiome
  • Suppressing appetite-stimulating brain cells in the hypothalamus
  • Increasing leptin sensitivity
  • Suppressing appetite by increasing lactate production
  • Reversing age-related metabolic changes
  • Altering bile absorption
  • Changing signaling in the gut
Why does metformin have a black box warning?

Metformin carries a black box warning for a rare side effect called lactic acidosis.

Lactic acidosis can be life-threatening, so it is important to let your healthcare provider know if you have a history of kidney disease.

Other risk factors for lactic acidosis include being over age 65 or having a history of:

  • Heart attack
  • Coma
  • Heart disease
  • Stroke

Some medications can also increase your risk of metabolic acidosis, so it’s important to tell your healthcare provider about every medication you are taking.

How would you know if you have metabolic acidosis?

Symptoms of metabolic acidosis include:

  • Weakness or pain
  • Nausea
  • Vomiting
  • Stomach pain
  • Decreased appetite
  • Rapid or deep breathing
  • Shortness of breath
  • Dizziness
  • Lightheadedness
  • Abnormally fast or slow heartbeat
  • Skin flushing
  • Muscle pain
  • Feeling cold, especially hands or feet
Can I take bupropion and naltrexone together?

Yes, low-dose naltrexone and bupropion are used together, along with a low-calorie diet and exercise, to help you lose weight and keep it off.

How much weight can you lose on naltrexone and bupropion?

Researchers found that low-dose naltrexone and bupropion is a very effective combination for weight loss. When used in combination with a low-calorie diet and exercise, participants in one study lost over 5% of their body weight.

How does oxytocin cause weight loss?

Several research studies have demonstrated oxytocin’s ability to modulate appetite and reduce cravings.

Oxytocin can cause weight loss by:

  • Reducing appetite
  • Promoting fat breakdown
  • Facilitating energy consumption
  • Stimulating satiety centers in the brain
  • Activating brown fat

Oxytocin decreases food and calorie consumption by reducing the appeal of foods that are high in fat and calories.

What is Bella?

Six Medications That Independently Reduce Cravings and Modulate Appetite

Bella+ is a combination of several drugs that independently have shown tremendous promise in supporting weight loss. These medications act on the hypothalamus of the brain to reduce cravings and suppress hunger, making it easier for you to control your appetite.

Naltrexone and Bupropion: A Proven Combination for Weight Loss

Naltrexone is an opioid receptor agonist, and bupropion is a dopamine and norepinephrine reuptake inhibitor. This combination has been prescribed for years to enhance weight management efforts in overweight or obese adults. Together these two medications activate a part of the brain that controls hunger.

Oxytocin Reduces Cravings and Increases Satiety

Animal studies have revealed that oxytocin reduces the desire for food intake, increases energy expenditure, and increases fat breakdown. In people, it decreases cravings for high-calorie foods and increases satiety. Studies show that oxytocin levels decrease with age.

Oxytocin is also integral to the stress response. It dampens the brain’s response to stress, reducing anxiety.

Researchers discovered that restoring oxytocin levels also boosted the activity of muscle stem cells, potentially increasing calorie-burning muscle cells.

Metformin and Topiramate Control Blood Sugar

Metformin is a prescription medication used to treat type 2 diabetes. Several large-scale studies have shown its effectiveness in weight loss, by regulating hunger in the brain, reversing changes associated with aging, or altering the microbiome in the gut.

Weight loss was a noted side effect when topiramate is used to treat seizures.

Vitamin B12 Boosts Metabolism

Vitamin B12 has been linked to weight loss, and deficiencies may increase the risk of obesity. Several studies have found a link between low vitamin B12 levels and type 2 diabetes, high blood pressure, obesity, and metabolic syndrome.

Bella+ combines these well-studied compounds that synergistically work in the brain to control your cravings and modulate your appetite while also improving sleep quality, decreasing anxiety, and improving a sense of social connection.

How Does Bella Work?

Bupropion and Naltrexone Reduce Cravings and Suppress Hunger in the Brain

Bella is made up of six drugs, each of which is known for its potential to support weight loss. Bupropion is a norepinephrine reuptake inhibitor, and naltrexone is an opioid receptor antagonist. Bupropion and naltrexone work together in the hypothalamus to reduce cravings and hunger. They activate POMC neurons in the hypothalamus, a brain region that produces a neurotransmitter that reduces appetite. Naltrexone also blocks a feedback loop that attempts to down-regulate POMC neurons.

A reward center in the brain called the mesolimbic system is stimulated by pleasurable activities such as eating or even thinking about eating. Bupropion and naltrexone can regulate these feelings of pleasure, reducing cravings to eat.

Oxytocin Improves Appetite Control

Oxytocin is a nine-amino acid peptide hormone made in the hypothalamus. In animal studies, oxytocin administration resulted in sustained weight loss by reducing food intake, boosting energy expenditure, and promoting fat breakdown. Oxytocin may also impact blood sugar control, a benefit independent of weight loss.

When oxytocin nasal spray was tested in humans, it produced similar results, including weight loss, decreased caloric intake, increased fat breakdown, and improved insulin sensitivity.

Metformin and Topiramate Control Blood Sugar

Topiramate is an anti-seizure medication used to treat epilepsy and migraines that has weight loss as a known side effect. When tested in clinical trials, topiramate induced weight loss and improved blood sugar control in adults with type 2 diabetes and obesity. Some users reported that topiramate altered their sense of taste, which may also help with appetite control.

Metformin is a prescription medication used to control blood sugar in people with type 2 diabetes. Large studies have also demonstrated its weight loss potential. Metformin works by modulating appetite control centers in the hypothalamus, minimizing age-related decreases in muscle mass and metabolic changes, and altering the gut microbiome.

Vitamin B12 Improves Metabolic Efficiency

Vitamin B12 is a water-soluble vitamin that is involved in forming DNA and red blood cells. It may also help fight fatigue, boost energy, and support weight loss efforts. Research on how vitamin B12 affects metabolism is very limited. However, in a study that enrolled over 9,000 people, having high levels of B12 was associated with a lower risk of obesity.
