One of the newer diets to hit the scene is the Whole30 Program. Founded back in 2009, many have found success in following the program in terms of losing weight and feeling healthier than before. This diet is slightly different from some because it's not one that you practice long-term; rather, it's only for 30 days.

The Whole30 Program forces the dieter to cut out many different food groups. This includes sugar of any kind (both real and artificial), alcohol, grains, legumes (including peanuts, meaning no peanut butter), dairy and soy substitutions, carrageenan, MSG, sulfites, and any junk food that has any approved ingredients that make them Whole30-safe. The program's main mantra, "when in doubt, leave it out," is important because it will help you for times when you're unsure if something's OK to consume while on the Whole30 program.

The claims behind cutting out so many different foods, according to the program's founder, Melissa Hartwig, is that it encourages the dieter to eliminate foods that are considered to be detrimental to your health for 30 days. Hartwig claims that her program will change your tastes and your relationship with food because it gives your body a break from foods that might be hurting you and your health — both physically and emotionally. By changing your diet this way, you give your body a chance to improve and change in a positive manner.

So, what can you eat during the Whole30 program? That list is still quite long: meat, seafood, and eggs are the types of protein allowed. In addition, all vegetables and most fruits are acceptable, as well as foods with natural fats, herbs, spices, and seasonings. There are also foods allowed that should otherwise be prohibited on this program. This includes ghee (also known as clarified butter), fruit juice, some legumes, vinegar, coconut aminos, and salt. Explanations and clarifications on why these foods are OK to eat can be found in the program's rules online.

One rule that's stressed in the Whole30 program is that you are to not weigh or measure yourself during those 30 days. Rather, you must wait until the 30 days end before you can do exactly that. You can weigh yourself before starting so that you can compare the before and after of doing the program. The reasoning behind avoiding the scale, according to Hartwig, is because following the program is more about focusing on the program's aforementioned benefits. If you're more hung up on numbers and appearances, then you'll most likely miss the point of the Whole30 program — and that's to become healthier.

That's not to say that you can't lose weight while doing this. However, it will require a lot of time for meal planning, grocery shopping, and cooking meals that follow the program's strict rules. Meal prepping everything—even snacks—can make you feel prepared, especially in cases where you don't have any Whole30 approved food options at your disposal.

Another big rule is that screwing up during the program is not okay. If you eat anything that's not Whole30 approved, you are to begin the entire program the very next day at square one. This can make the prospect of failing possible, especially if you're someone with little to no willpower around sweets (or anything else not approved on the program). The biggest thing to remember, according to Hartwig, is that this is only for 30 days —that's it. There'a tough love approach that comes with Whole30, but it's designed for those that have failed with other diets because it strongly encourages to stick with it for just 30 days. It won't be easy, but Hartwig believes that anyone can succeed in the Whole30 program.

So after you successfully complete the Whole30 program, what do you do if you want to resume foods that were banned? The best thing to do, according to Prevention, is to slowly reintroduce those banned foods back into your diet to see how your body reacts. Seeing how they make you feel after going without them for so long will help you better judge if it's OK to eat or not. For example, if after reintroducing gluten in your diet, you find that you feel unwell, you'll better know that that's the case. This will push you to cut gluten out of your life for good. The same goes for all foods not approved for the Whole30 program. Doing this slowly will be less of a shock to your body, and will less likely make you feel gross or fat.

The Whole30 program is a unique take on dieting that's extremely strict and unforgiving. It forces dieters to eliminate many foods while at the same time not allowing them to make any mistakes. However, following this program will help determine what foods make you feel good, and which don't. It also will encourage paying more attention to what you eat, as well as cooking and meal planning more instead of relying on take-out or processed foods. If there's enough willpower and desire to want to become healthier or lose weight, anyone can succeed in doing the Whole30 program.
