It is important to note that the difference between a caloric deficit than other diets is that this must be a lifestyle change. You cannot be in a deficit and get down to your desired weight then begin eating the way you did beforehand as you will gain the weight back. At a certain point in the deficit, you may plateau, which means that you will not continue to lose weight as your energy expenditure and caloric intake will be equal. In this case, you would increase the energy expenditure again, perhaps decreasing more calories eaten or increasing exercise calories burned. This process is repeated until the desired result in obtained. ** Please consult a doctor when beginning a weight loss journey to ensure they agree with your methods and are able to monitor potential conditions that may arise.

The concept of a caloric deficit refers to intaking less calories than you are expending. For example, if you are consuming 2,000 calories but burning off 2,200, you will be in a caloric deficit. Despite much controversy, this is the only way to lose weight. When looking at the chart to the left, it can be noted that Exercise Activity Thermogenesis (EAT) only makes up about 5% of energy expenditure, therefore exercise makes up the smallest portion of energy burned through the day. Thermic Effect of Food (TEF) refers to how much energy is expended when you are digesting your food. Foods high in protein take longer to digest, which requires more energy. Non-Exercise Activity Thermogenesis is movement that is not considered exercise, this can include your daily step count, bouncing your foot or fidgeting, taking the stairs instead of an elevator, or daily activities like gardening or chores. Your Basal Metabolic Rate (BMR) is how much energy you would expend if you laid in bed doing nothing all day. It refers to the minimum amount of energy (calories) your body needs to perform essential functions at rest, such as breathing, blood circulation, and maintaining body temperature.

So if exercise makes up so little energy expenditure, how do we lose weight? Well, there are ways to increase the other portions in addition to exercise. Eating foods that are more difficult to digest such as complex carbohydrates and protein will increase energy uptake. Increasing your muscle mass will increase your BMR as it is an active tissue, meaning that it has the ability to generate force, which requires energy. If you are active, muscles also need energy to recover as the body has specific functions to rebuild the torn muscle fibers. Increasing your step count, parking father from the entrance to a building, or increasing hobbies with movement such as gardening or playing with your pets will increase the NEAT portion.

One pound of fat is equivalent to 3,500 calories. This means that if you are in a 500 calorie deficit every day, you can healthily lose 1lb a week! To do this attainably, it could be recommended to find your daily caloric intake and subtract 200 calories in food, then performing 300 calories in exercise. To find your caloric intake, see the resource below.

The Keto Diet is a low carbohydrate high fat diet, which is advertised to help people lose weight. This diet consists of 55-60% fat, 30-35% protein, and 5-10% carbs.

The purpose of the diet is to bring the body to a level of ketosis, which is a metabolic state where the body mainly burns fat instead of glucose (stored sugar). 

The National Institute of Healthy (NIH) has stated that the keto diet may help with weight loss, visceral adiposity (increasing body fat), and appetite control. Other sources have claimed that the diet helps children with epilepsy, and diabetics to regulate blood sugar levels.

Detriments in health due to the keto diet include bad breath, insomnia, fatigue, constipation, dizziness, brain fog, muscle soreness, thirst, and reduced athletic performance. The main problem with the keto diet is that it is a short term solution that will likely not work long term because people who eat keto will regain the weight they had lost when they begin eating "normally" again. With keto, people are almost completely depleting the body's first source of energy, carbs, therefore they are typically very tired and often do not have much energy. A better solution to this diet is an increase in nutrient dense foods, and a reduction in "unhealthy" foods such as fried, high fat, low protein/carb foods.

Veganism is a way of life that involves avoiding animal products and cruelty to animals. It's based on a philosophy that rejects the idea that animals are commodities. 'Vegans' eat plant-based foods like vegetables, fruits, grains, and nuts. They avoid animal products like meat, dairy, eggs, honey, and gelatin.

Potential harmful effects of a vegan diet include: nutritional deficiencies, particularly in Vitamin B12, calcium, iron, zinc, and omega-3 fatty acids, which can lead to issues like anemia, weak bones, fatigue, and hair loss if not properly supplemented or planned for through a diverse plant-based diet. Other potential concerns include digestive problems like bloating, and in some cases, an increased risk of developing eating disorders due to obsessive focus on healthy eating patterns (orthorexia) when not managed carefully.  One positive of this diet is that it can increase heart health by lowering cholesterol and blood pressure due to avoiding meat, which can reduce the risk of heart disease. Red meat can increase the risk of heart disease through its high levels of saturated fat and the chemicals produced by gut bacteria when digesting it. Vegans will sustain their protein intake by consuming products such as tofu, nuts, beans, chickpeas, and seeds among many other sources.

The Paleo diet, also known as the Stone Age diet, is a dietary pattern that aims to mimic the foods consumed by humans during the Paleolithic era which began around 2.6 million years ago and ended around 10,000 BC. Those on the Paleo diet will eat foods such as fruits and vegetables, lean meats (such as beef, chicken, fish), eggs, nuts and seeds, healthy fats (such as olive oil, avocado oil), and avoid foods such as grains (such as wheat, rice, corn), legumes (such as beans, lentils), dairy products, processed foods (such as sugary drinks, snacks, fast food), and refined sugars.

Benefits include:

The Paleo diet is typically high in protein and healthy fats, which can promote satiety (reduced hunger) and reduce calorie intake causing weight loss. Improved blood sugar control by excluding grains and refined sugars which can help regulate and maintain blood sugar levels. The diet's focus on whole, unprocessed foods may reduce inflammation in the body. Improved heart health due to the high intake of fruits, vegetables, and healthy fats which may lower cholesterol levels and reduce the risk of heart disease. 

Drawbacks 

The Paleo diet can be restrictive and difficult to follow, especially for people who enjoy certain foods like grains and dairy. If not carefully planned, the Paleo diet can lack essential nutrients such as calcium, vitamin D, and fiber. Organic, grass-fed meats and other high-quality ingredients can be expensive. While there is some evidence to support the benefits of the Paleo diet, more research is needed to confirm its long-term health effects.

The Mediterranean diet is a traditional eating pattern based on foods consumed in countries bordering the Mediterranean Sea, such as Greece, Italy, Spain, and Turkey. It emphasizes plant-based foods, healthy fats, and moderate consumption of animal products. Those who consume this diet eat fruits, vegetables, whole grains, legumes, healthy fats such as extra virgin olive oil, avocados, nuts, and seeds, lean fish, poultry, eggs, and dairy products (in moderation), and minimal consumption of sugary drinks, refined grains, and processed meats. Research has shown that the Mediterranean diet may provide numerous health benefits, including reduced risk of heart disease, stroke, and type 2 diabetes, improved cognitive function and mood, lowered risk of certain types of cancer, and extended lifespan. One consideration for this diet is that those with seafood or nut allergies would be unable to follow to precision.

Intermittent fasting (IF) is an eating pattern that cycles between periods of fasting and eating. It is not a specific diet but rather a framework for meal timing. 16/8 method: Fasting for 16 hours and eating within an 8-hour window each day. 5:2 method: Eating normally for 5 days a week and restricting calories to 500-600 on 2 non-consecutive days. Alternate-day fasting: Fasting one day and eating normally the next. Eat-stop-eat: Fasting for 24 hours once or twice a week.

IF may promote weight loss by reducing calorie intake and boosting metabolism. It may improve insulin sensitivity, blood sugar control, and cholesterol levels. Intermittent fasting may decrease inflammation markers, which can benefit conditions like arthritis and heart disease. Some studies suggest that it may slow down aging and improve brain function. 

Precautions:

Consult your doctor: IF may not be suitable for everyone, especially those with underlying health conditions such as diabetes, eating disorders, or pregnancy. Start gradually: Begin with shorter fasting periods and gradually increase them over time. Stay hydrated: Drink plenty of water during fasting periods. Eat healthy meals: Focus on consuming nutrient-rich foods during eating windows. Listen to your body: If you experience any adverse effects, such as dizziness, fatigue, or headaches, stop fasting and consult your doctor.

A detox juice cleanse diet typically involves consuming only juices made from fruits, vegetables, and sometimes herbs for a set period of time—anywhere from a few days to a week. The goal is to “cleanse” the body by flushing out toxins, improving digestion, and promoting overall health. It’s often marketed as a way to lose weight, boost energy, and improve skin.

Benefits include Increased Nutrients: Juices are rich in vitamins, minerals, and antioxidants, which may support overall health. Hydration: The high water content of juices can keep you hydrated. Weight Loss: By eliminating solid foods and reducing calorie intake, some people experience short-term weight loss. Improved Digestion: The fiber from certain vegetables and fruits can support digestive health.

Considerations include Lack of Fiber: While juices provide nutrients, they lack fiber, which is important for gut health and satiety. Low Protein and Fat: These cleanses tend to be low in protein and healthy fats, which are essential for maintaining muscle mass and overall health. Energy Levels: Some people experience fatigue or irritability due to the low-calorie nature of a juice cleanse. Short-Term Results: Any weight lost during a juice cleanse is often temporary and can be regained once regular eating habits are resumed.

Weight Watchers (now called WW) is a popular weight loss program that emphasizes a balanced, sustainable approach to losing weight. It was founded in 1963 and has evolved over the years, but the core philosophy remains the same: helping people achieve a healthier lifestyle by focusing on behavior changes and developing healthier habits. WW uses a points-based system called SmartPoints to guide food choices. Each food item is assigned a certain number of points based on factors like calories, fat, protein, and sugar. Healthier foods (like fruits and veggies) have lower point values, while less nutritious foods (like junk food) have higher points. SmartPoints: The number of points you’re allotted each day is based on factors like your age, gender, weight, height, and activity level. You can also earn extra points through physical activity. ZeroPoint Foods: Many fruits, vegetables, and lean proteins (like chicken breast) are considered "zero-point" foods, meaning you don’t need to track or count them. This encourages people to eat more nutrient-dense, lower-calorie foods. Personalization: WW tailors the program to each person’s specific needs and goals. You can follow it through an app or website where you can track your food, activity, and weight loss progress. The app also offers access to personalized recipes and meal plans. Flexibility: One of the main selling points of WW is its flexibility. Unlike other diets that restrict certain foods, WW encourages moderation, allowing you to indulge in your favorite foods as long as you stay within your point budget. This makes it easier for people to stick with the program long-term.

Gluten-free refers to a diet that excludes foods containing gluten, a protein found in wheat, rye, and barley.  People choose this diet for a variety of reasons, the most common being due to celiac disease and gluten sensitivity. Celiac disease is an autoimmune disorder where the body's immune system damages the small intestine when gluten is consumed. People on this diet will consume fruits and vegetables, grains and starchy foods such as rice or quinoa, gluten free bread, proteins such as animal and dairy products, as well as fats and oils.
