Is your diet forcing you to ditch all your favorite delicacies? Are you searching for a diet that can help you lose weight without compromising on the foods you love? The '5 Bite Diet' might seem like the perfect solution. This low-calorie diet restricts your calorie intake with some simple rules and regulations, claiming to help you reduce weight equivalent to a weight loss surgery. But is it too good to be true? This article dives into the 5 Bite Diet, examining its claims, potential results, and crucial considerations.
What is the 5 Bite Diet?
The 5 Bite Diet is an extreme weight loss plan created by Dr. Alwin Lewis in 2007, a California-based physician, as a part of his book 'Why Weight Around?' The diet gained attention following the release of his book Why Weight Around? Dr. Lewis explained that this diet can give results same as a gastric bypass surgery which is used to reduce belly fat. Dr. Lewis further elaborated that with this diet one can lose weight without spending hours at the gym, without giving up on any foods and you do not have to count calories as well. It promises rapid weight loss by severely restricting food intake, similar to the effects of gastric bypass surgery but without the procedure.
How Does the 5 Bite Diet Work?
The 5 Bite Diet's central premise is that by learning to eat like a person who has undergone gastric bypass surgery, you’ll shed the weight without needing the procedure. Here's a breakdown of the diet's core principles:
- Skip Breakfast: The diet encourages you to skip breakfast, drinking only black coffee or tea instead.
- Limited Bites for Lunch and Dinner: Eat just 5 bites of food per meal for lunch and dinner (10 bites total per day). A person has to eat a very restricted quantity and can enjoy 10-12 regular sized bites per day.
- Prioritize Protein: Each meal should begin with a bite of protein (meat, fish, eggs, or beans). During this diet, you need to make sure that you add protein-rich food to your meal at least once a day. Meat, eggs, dairy, tofu, fish or legumes are some of the options you can choose from.
- Eat What You Want (Within Limits): No food is off-limits, as long as you only take 5 bites.
- Non-Caloric Beverages Allowed: Water, black coffee, and unsweetened tea are permitted throughout the day. The 5-bite diet allows only zero-calorie liquids, but doesn't limit them. This means you can drink as much water, coffee, tea, and diet soda as you like. Since these liquids have no calories, they don't affect your weight directly.
- Snacks (Optional): You may also have a bite of food between meals for a maximum of two, one-bite snacks each day.
- Supplements: To cover any potential nutrient deficiencies, it’s recommended to take a multivitamin and omega-3 supplement each day.
- Exercise: Low-intensity exercise is allowed, but moderate- and high-intensity workouts should be avoided on this diet.
Example Meal Plan:
- Breakfast: Black coffee
- Lunch: 5 bites of anything you like.
- Dinner: 5 bites of anything you like, aiming for at least one bite of protein.
- Snacks: Up to two single bites of anything you like.
Potential Benefits of the 5 Bite Diet
As with all low-calorie diets, the 5 Bite Diet is likely to help you lose weight - at least initially. Limiting the amount of food you eat to a maximum of 10-12 bites each day will naturally cause you to eat fewer calories than your body requires. The 5 Bite Diet may offer some benefits, most of which are linked to its ability to promote weight loss.
- Rapid Weight Loss: The fad diet promises to help you lose up to 6.8 kilos per week. The diet claims to mimic the effects of gastric bypass by restricting food to a fraction of normal intake. A short-term crash diet can help by motivating you with some immediate weight loss.
- Simplicity: No calorie counting or complicated meal prep. Proponents most frequently mention that the diet doesn’t place any restrictions on what you eat and only focuses on how much you eat. Therefore, dieters don’t have to give up their favorite foods to lose weight.
- Portion Control Training: The five bites diet has given me a new appreciation for eating a full meal and feeling that satisfying sensation after a proper lunch or dinner. The 5 Bite Diet makes you conscious about what you are eating.
Health Improvements Associated with Weight Loss:
- Reduced Joint Pain: Research shows that losing even as little as a 5-10% of your body weight can help reduce joint pain.
- Lower Risk of Type 2 Diabetes: Studies further indicate that losing weight may lower risk factors for heart disease, such as triglyceride, LDL (bad) cholesterol, and blood pressure levels.
- Improved Cardiovascular Health: Studies further indicate that losing weight may lower risk factors for heart disease, such as triglyceride, LDL (bad) cholesterol, and blood pressure levels.
Risks and Side Effects of the 5 Bite Diet
However, this weight loss may be accompanied by several health risks. Plus, the risk of weight regain once you go off the diet is very high. This diet should only be followed under medical supervision. This extreme diet raises serious health concerns due to under-eating. Multiple studies confirm that consuming just 10 bites of food a day is nowhere near sufficient to support basic physiological needs.

- Nutritional Deficiencies: It’s nearly impossible to meet your nutrient needs by eating so few calories each day, even if your diet includes nutrient-rich foods. This can lead to side effects like fatigue, dizziness, constipation, and even loss of bone density. Consumption of fewer calories can lead to nutrition deficiency which can trigger long term health issues. Therefore, it is advised to switch to a nutrition rich diet after losing the desired amount of weight. The risk of nutrient deficiencies is especially high in those who need to lose considerable amounts of weight, as they follow this nutrient-restricted diet for longer. "Though Dr. Lewis suggests people take a multivitamin and make sure their 10 daily bites includes at least some protein, this is simply not enough to get people all the vitamins, minerals and other nutrients they need to support all the functions that the body needs to perform on a daily basis", say's Dr Oz on his blog.
- Metabolic Slowdown: Consistently eating fewer calories than your body needs may lead to muscle loss and slow your metabolism. In turn, a slower metabolism makes it more difficult to maintain your weight loss and increases your risk of weight regain over time. Low-calorie intake can also contribute to digestive issues, increased risk of gallstones and eating disorder.
- Risk of Weight Regain: Eighty percent of people who lose weight from dieting gain the weight back within a year. The severe food restriction can lead to metabolic slowdown, nutritional deficiencies, and disregulated hunger hormones. Quick fixes like this don’t create lasting change which leads to binging.
- Disordered Eating: Evidence also suggests that severely restricting calories, as is encouraged with this diet, may increase your risk of binge eating behaviors. Therefore, this diet is especially unsuitable for people prone to or with a history of disordered eating behaviors. It can also result in poor metabolism and can also put you at an increased risk of weight regain. The restrictive structure can encourage obsessive or unhealthy behaviors around food.
- Other Side Effects: Fatigue, irritability, hair loss, and muscle loss are common outcomes of extreme caloric restriction.
Is the 5 Bite Diet Sustainable?
Most experts agree that this approach is unsafe and not viable for long-term health. The 5 Bite Diet may promise fast results but at a serious cost. From particular to general, the challenge of sticking with a weight-loss plan that's both healthful and effective.
Expert Opinions and Alternatives
"We really need to shift our conversation away from what exactly people should be eating to how do you change their behavior, how do you get people to make long-term changes," Pagoto says.
Another healthier alternative to the 5-bite diet would be to follow the USDA's MyPlate program, simply fill half of your plate with non-starchy vegetables and fruits and divide the other half between whole grains and a lean protein source. In other words, don't get on the 5 Bite Diet no matter how desperate or eager you are to lose weight. The promise that you'll be allowed to eat whatever you want (albeit in such small quantities) should not make you forget that nutrition is also important.
