If you're looking to lose weight and treat or prevent high blood pressure, DASH is an excellent option. This diet includes foods that are rich in potassium, calcium, and magnesium which can help control blood pressure. It also limits foods that are high in saturated fats, sodium, and added sugar. There's also a lower sodium version of DASH if you're trying to cut your intake, but as always consult with your doctor to see if DASH is a good option for you.

When following the DASH diet, meals will consist of vegetables, fruits, whole grains, poultry, fat-free or low-fat dairy products, beans, and nuts. The idea is that these eating habits stick with you after you've completed the program since the incorporated foods can be found easily at your local grocery store.

It incorporates healthy fats, beans, fruit, leafy greens, whole grains, and recommends you eat fish at least twice a week.

Flexitarian Diet

flexitarian diet

SPECS

  • How it works for weight loss: Focuses on filling your plate with more fruits, vegetables, whole grains, and plant proteins
  • Coaching available: No
  • Trial period: No

Eating plants and plant-based foods, incorporating dairy and eggs, and eating meat in smaller portions and less frequently is the core of the Flexitarian Diet. This diet is a blend of vegetarianism and flexibility because there is no set calorie or macronutrient goal—just a focus on eating plants. Nothing is officially off limits here, but the goal is to increase plant-based foods over time that way other foods are eaten less frequently or in smaller portions. Eating a more plant-focused diet is said to reduce the risk of heart disease, diabetes, and certain types of cancer.

Each meal is built with fruits, vegetables, whole grains, legumes, and healthy fats. Opting for protein from sources such as soy foods, legume, nuts, seed, dairy, and eggs are always at the forefront. Meat can be incorporated from time to time, being mindful of portion sizes. The idea is that after consuming more nutrient-dense foods, you'll naturally reduce the number of foods that are higher in calories, saturated fats, and added sugars.

What We Like

  • Ideal for vegetarians, vegans, or those trying to reduce meat consumption
  • No caloric goal can support intuitive eating
  • Implements nutrient-rich whole foods
  • May reduce the risk of heart disease, diabetes, and certain types of cancer

What We Don't Like

  • May be hard to follow if you're used to eating meat
  • Not having a structured plan may not be suitable for those just starting out

Intermittent Fasting

Intermittent Fasting with Do Fasting

SPECS

  • How it works for weight loss: Helps to limit overall calorie consumption and increase weight loss by limiting eating hours and fasting throughout the day
  • Coaching available: No
  • Trial period: No

CHECK PRICE

The goal of Intermittent Fasting is to limit or completely eliminate calories during specified hours each day, which can help decrease your appetite by slowing your metabolism. How many hours you fast versus how many hours you eat is up to you. One popular option is to restrict eating to an eight hour window, leaving the other 16 hours for fasting. An example of this would be eating from noon to 8 p.m. and then restricting or eliminating calories outside of this window. How many calories you consume is also up to your discretion, which is something to consider when choosing this diet.

Since there are no caloric goals or food restrictions, this diet is very easy to follow. However, it's important to make sure you're choosing nutritious foods so your body is getting the nourishment it needs to power you through your day. This diet could be a slippery slope if you have trouble finding nutrient-dense foods since it does not have any resources or plans for you to follow.

What We Like

  • Tracking calories and foods is not necessary
  • Meal choices and food options are completely up to you
  • You can choose the times and duration of your fasting period based on your needs

What We Don't Like

  • Busier and sporadic schedules could make fasting and strict eating times hard to follow
  • Some may find fasting hours too restrictive and may overeat
  • Skipping meals or fasting may be dangerous for some medical conditions

How to Choose the Best Diet for Weight Loss

Goals

While many diets for weight loss support the obvious goal to lose weight, some plans also support different lifestyles and dietary needs. For instance, some people may want to lose weight and also focus on eating foods that can help lower cholesterol. Others may want to follow a low-carb or ketogenic diet because that's what their doctor recommends. Other times, a weight loss diet may be more concentrated on plant proteins, which is a suitable option for those who are trying to lose weight and eat less meat. No matter what your circumstances are, it's always a good idea to consult with your doctor to decide which is the most beneficial to your overall health and wellness.

Flexibility

Chances are, if you're feeling overly restricted you're probably not going to stick with a diet consistently to reach your goal. Certain diets for weight loss are pretty flexible in terms of foods you can choose, so long as you don't exceed your daily caloric goal. This can help establish the healthy habit of picking foods that have a lower caloric impact, so you can eat a higher volume. Having flexibility can also instill the mentality that you can have treats here and there as long as you're balancing those choices with healthy ones.

If you choose a weight loss diet that has less flexible food options such as a low-carb diet, the good news is that there are so many recipes and products available now that serve as a good substitute for options that aren't suitable. If you need to choose one of the more restrictive diets, it's always a good idea to pick a plan that includes recipes or meals so you have plenty of options for delicious meals.

Sustainability

Sustainability not only refers to whether or not you can finish what you started but also to choosing a plan that helps you keep the weight off after you're finished. When considering diet plans for weight loss, look for plans that include foods from a variety of food groups and a treat here and there. Likeability is also really important because chances are if you're not enjoying the foods you're eating you won't make long-term lifestyle changes. Your weight loss diet should also have the right amount of nutrients and calories, so you don't feel deprived or gain weight from overeating.

Dietary Needs

Dietary needs vary from person to person and usually include a conversation with your doctor. Whether you're making a personal choice to avoid certain foods or avoiding them for health reasons, choosing a plan that aligns with your needs will more likely result in reaching your goals and increasing your overall well-being.

Nourishment

When thinking about nourishment, it's best to follow a diet that isn't so restrictive that you feel weak or hungry throughout the day. Even though you're trying to lose weight, your body still needs proper nutrients to function well, even more so if you're incorporating exercise. It's also important to pick a diet that includes a hearty amount of whole foods including fruits and vegetables over processed foods.

Budget

Overall, you'll want to find something that is going to help you reach your weight loss and overall health goals. Depending on your needs and experiences, you may opt for coaching which is usually more expensive but can be a really helpful tool if you're looking for support and accountability. Some weight loss plans also include meals or protein shakes which are more convenient but cost more than preparing your own meals and snacks.

Program Length

How long you follow a program depends on which program you choose and your goals and preferences. We like to think of weight loss as a marathon, not a race. There's not one specific amount of time that works for everyone simply because everyone is different. Some studies claim that it takes four to six weeks to establish healthy habits and lose weight. Since this may not be the case for everyone, we recommend choosing a length that you think you can follow consistently. That way when you're finished, you can choose to continue with the program or think about trying other diets for weight loss if you're not happy with your results.

Coaching and Community

If you're trying to decide if coaching is right for you, think about them as a personal support system that can help you through your weight loss journey. Typically if you're just starting out or if you feel like you don't know a lot about choosing healthy foods, a coach is a good idea. Even if you feel confident in your nutritional knowledge, checking in with a coach can help keep you accountable.

Another way to feel accountable and connect with others is to choose a diet for weight loss that has a community you can participate in. Communities are great for posting any questions you may have or sharing recipes. They're also an awesome way to bond with others as you face the same challenges that may come when following a weight loss program.
