Editor’s Note: This list has been updated to contain the only the most effective weight loss diets available in 2018. Diet #1 is our recommendation (as results are guaranteed), but any diet in this roundup is great – happy reading!

It’s no secret that as a species, we’re getting fatter, which is why finding a diet to keep you at a healthy body weight is critical. Never has it been more important for consumers to be informed; that rule is especially applicable to those who are shopping for weight loss diet plans.

The weight loss market in the US alone is worth over $66 billion, and that number only continues to grow, being forecasted to be worth $245 billion by 2022. This booming industry has spawned an army of would-be “armchair dietitians” that have flooded the internet with a whole host of bogus “lose weight quick guides” to cash in.

It seems like every week,another new diet book enters the market, claiming to be the “best diet for fast weight loss”, falsely promising its followers remarkable results with no effort whatsoever. Deception and false-statements are running rampant within the diet industry, as many shady companies have realized the fastest way to make a quick buck is to simply lie and swindle.

Everybody knows that losing weight is a very difficult task to do on its own; the last thing you want is additionally added stress worrying that you’ve been conned into buying a fad diet plan that simply doesn’t work.

Luckily for you, that’s something you don’t need to worry about anymore now that you’ve stumbled across this page. Here at DietProbe, our team of fully qualified nutritionists and dietitians have painstakingly analyzed pretty much every single diet for weight loss out there.

To guide you on your path towards making an informed choice, we’ve narrowed them down to this top 10 best weight loss diets list (sorted by effectiveness); any diet on this list will be an excellent choice.


    Top 10 Weight Loss Diets - Ranked On Effectiveness

    Position: Analysis:
    1.The Hard & Fast Diet Book Cover
    After reviewing just about every single diet plan out there, we had to place The Hard & Fast Diet in position #1 of our best rated weight loss diets list. Without mincing words, this is the best we have came across bar none.

    This best-selling diet is proving to be extremely popular, as it's designed to produce results in the shortest possible amount of time.

    When you're choosing a diet plan, the most important thing is whether it actually works. After thoroughly researching this diet, we've concluded that this is very likely the most effective one out there; you could be looking at drastic changes to your body fat in a matter of weeks, not months or years.

    As is implied in the name, the diet is both hard and fast! It'll require some willpower (as all good diets do), but if you follow the plan as instructed we believe it's a fool-proof method of rapidly losing weight.

    The author Michael Keane has put the Hard & Fast Diet together for those who just want to be looking good and feeling good as soon as possible, which is probably 99% of dieters!

    Summary:

    The fastest method of losing weight.
    Triggers rapid fat loss.
    Completely safe and healthy.
    Very easy to follow.
    Isn't costly to sustain.

    2.VLCD Diet
    We've placed the VLCD (very low calorie diet) in the second slot of our best diets for weight loss list due to the clinically-proven nature of the diet itself. As is implied within the name, the VLCD is essentially a crash diet that puts followers on a massive caloric deficit, triggering weight loss at a constant pace.

    The VLCD has seen a surge in popularity, being utilized by various different meal replacement shake companies.

    While the VLCD is often stuck to using low calorie meal replacement shakes for breakfast, lunch and dinner, you can actually eat any type of food you'd like while following this diet; you just need to ensure the you do not exceed the daily allocated amount.

    Again, this is another diet that's going to require some willpower, but that is true for any diet that actually works.

    Summary:

    A proven method of losing weight.
    Completely safe and healthy.
    Very easy to follow.
    Isn't costly to sustain.

    3.The Keto Diet
    Unless you've been living under a rock, you've probably heard about how the Keto Diet is one of the best diets to lose weight fast. We have placed it in slot #3 of our list due to it being so effective and one of the most user-friendly diets out there.

    Following this diet involves sticking to a caloric deficit while also keeping your carbohydrate intake to a minimum; in doing so, you'll eventually push your body into ketosis - a state where the body starts burning body fat reserves as its primary source of energy.

    The keto diet is one that requires a little more monetary investment than most other diets, simply due to the foods required to sustain it. As you'll be dropping almost all of the carbs from your diet, you'll be eating a lot of protein and healthy fats, which can be a little costly.

    Costs aside, we believe that if you're genuinely looking for a good weight loss diet, keto will be a excellent choice and the results will speak for themselves.

    Summary:

    A proven method of losing weight.
    Completely safe and healthy.
    Very easy to follow.

    4.The 5 2 Diet
    Without a doubt, the 5:2 diet is one of he most effective diets for weight loss. This particular diet utilizes a modified intermittent fasting method and combines it with a traditional calorie controlled diet.

    The name 5:2 literally describes the format of the diet; five days per week (the "non-fast days") the dieter will stick to a maximum of 2000 calories consumed each day - these calories should come from non-processed, low-in-sugar organic foods. The remaining two days per week (the "fast days") the dieter will not exceed 500 calories consumed each day.

    This method of "crash dieting" two days per week is what makes the 5:2 diet so effective for consistent weight loss, as those two days work to jumpstart your body into fat-burning mode.

    While this diet isn't renowned for causing "rapid weight loss", it will deliver consistent results if you follow the directions carefully over a sustained period of time.

    Summary:

    A proven method of losing weight.
    Completely safe and healthy.
    Very easy to follow.
    Isn't costly to sustain.

    5:2 Diet Review

    5.Intermittent Fasting Diet
    Much like the 5:2 Diet, the Intermittent Fasting diet has followers periodically reducing their daily caloric intake significantly at intervals throughout the week.

    We have placed the Intermittent Fasting (IF) diet plan in our top 10 diets for quick weight loss list primarily because of how easy it is to follow, but also due to it being the diet that has very likely played a huge part in the survival of the human species over the millennia!

    Several different scholars have referred to this dieting technique as "the ancient secret of weight loss".

    If you think we're over exaggerating, we're not; obesity in humans is a very recent health problem, only rearing its ugly head in the last 200-300 years. Researchers have stated that ancient man never experienced obesity-related health problems due to regularly going through periods of feast and famine. Nowadays food is so easily accessible that becoming overweight is a very real likelihood.

    By following an intermittent fasting diet, you'll essentially be tricking your body into burning your excess stored body fat as its main fuel source, after all, we're genetically hardwired to use fat for energy during periods of famine.

    Summary:

    A proven method of losing weight.
    Completely safe and healthy.
    Very easy to follow.
    Isn't costly to sustain.

    6.The Low Carb Diet
    One common theme you're probably noticing in our best diets list is that many of them are preaching minimal carbohydrate intake, and it'll come as no surprise that the Low-Carb Diet (LC Diet) adds to this chorus.

    If it seem suspiciously similar to the Keto Diet, that's because it is. The main fundamental difference is that the Low-Carb Diet is significantly easier to stick to (i.e. requires less willpower and dietary commitment) and is less harsh on the body; it is designed for slow and steady weight loss rather than for rapid results.

    The biggest selling point for this diet is that it can actually be sustained indefinitely to help keep you at a natural body weight for years to come.

    Research has shown that the Low-Carb Diet has numerous health benefits and is often referred to as a diet for longevity and good health - some research has even shown that those who follow the Low-Carb Diet have a lesser likelihood to developing cancer.

    Summary:

    A proven method of losing weight.
    Completely safe and healthy.
    Very easy to follow.
    Isn't costly to sustain.

    7.The Atkins Diet
    The Atkins Diet (sometimes known as the Atkins Nutritional Approach) is a low-carb, high fat (LCHF) diet with a difference. It was released by nutritionist Dr. Robert Coleman Atkins, back in 1972 as "Dr. Atkins' Diet Revolution".

    Since its original launch, the diet has gone through multiple revisions, and in its current modern state is one of the most effective diets for losing body fat.

    Rather than just being your typical run-of-the-mill carbohydrate-limited deficit diet, it takes a very unique approach unlike many other weight loss plans out there. The Atkins Diet puts those who follow it on a protein-rich diet that limits carb intake to around 20-40 grams per day, the plan also doesn't apply any restrictions on how much fat the follower can consume (however there is a daily caloric amount that you must not exceed).

    The diet itself is broken up into 4 different phases:

    An "introductory" phase that adjusts you to a low-carb eating pattern, an "ongoing weight loss" phase which will help you reach a health body weight over a sustain period of time, a "pre-maintenance" phase which gradually grants the follower additional carbohydrates and finally, a "maintenance" phase which is sustained indefinitely to help sustain the follower's new weight.

    Summary:

    A proven method of losing weight.
    Completely safe and healthy.
    Very easy to follow.
    Isn't costly to sustain.

    8.The Paleo Diet
    Coming in at number 8 on our best diets for weight loss list is the Paleo Diet, also known as The Caveman Diet. What makes this diet so unique is that it's based on the eating habits of the hunter-gatherers during the Paleolithic era.

    This diet really is a "back to basics" style diet and puts into practice a whole load of things you probably already knew; you are not allowed any processed foods, no sugar or snack-foods are tolerated and certainly no alcohol is allowed. The Paleo Diet is all about eating clean and healthy - low-carb and high-protein foods will populate the majority of what you'll be eating; if the cavemen couldn't have it, you can't have it either!

    What's more, you don't even need to count your calories for this one (though we recommend that you do if you find yourself having a tendency to binge eat no matter what the food) - the general theory is that by significantly overhauling your consumed-foods to healthier options, the weight will naturally start to come off.

    Rather than being something that delivers fast weight loss, the Paleo Diet is designed to be a diet for life, and has many people who swear by it.

    Summary:

    A proven method of losing weight.
    Completely safe and healthy.
    Very easy to follow.
    Isn't costly to sustain.

    9.Banting Diet
    Another highly popular weight loss diet is The Banting Diet - this is another calorie-restricted program that reduces the follower's carbohydrate intake over a gradual period of time. The Banting Diet particularly focuses on eliminating high-in-starch foods and specifically foods that contain refined sugars.

    Unlike most other diets on this list that were created by those of a nutritional background, this diet was actually formulated back in the year 1820 by a British undertaker named William Banting. Despite the rather unorthodox origin, "banting for weight loss" has become something of a phenomenon, with millions of people worldwide vouching for it!

    Since its initial release, the Banting Diet has undergone numerous revisions and closely resembles the Atkins 4-step program, with one or two key differences. Followers of this diet will undergo: an "observation phase" which helps the dieter transition and adjust to the new medium-carb, sugar-free, gluten-free diet. A "restoration phase" which will slowly remove the carbohydrates from your diet. A "Transformation phase" which will help you reach a healthy body weight, and finally a "Preservation phase", which as the name suggests, will set you onto a diet that'll preserve your new body weight.

    Summary:

    A proven method of losing weight.
    Completely safe and healthy.
    Very easy to follow.
    Isn't costly to sustain.

    10.The Dukan Diet
    Last but by no means least is the Dukan Diet, a nutritional 4-step program that shares similar traits to the Aktins Diet and the Banting Diet. Formulated in 2000 by Pierre Dukan, a French doctor and nutritionist, the diet has continued to climb in popularity, having sold over 7 million copies worldwide.

    Followers of the diet will be placed on a high protein, low fat and low carb diet, and provided with a list of 100 different "approved foods" to mix and match. They will go through an "attack phase", a "cruise phase", a "consolidation phase" and finally a "stabilization phase".

    Dukan states that his diet is designed to help followers reach their "true weight", which is essentially the weight that your body is genetically meant to be at.

    If you're looking for a rapid weight loss diet, this isn't it - the Dukan Diet is not designed to produce such results, rather it should be viewed as a "diet for life" that'll help you reach a natural healthy weight (i.e. your "true weight") and sustain it indefinitely.

    Summary:

    A proven method of losing weight.
    Completely safe and healthy.
    Very easy to follow.
    Isn't costly to sustain.

    Dukan Diet Review


    What do we deem to be a good diet for weight loss? We look at three key aspects of a diet plan:

    These aspects are:

    1. Price – Prior to embarking on a diet, you’re probably going to need to purchase the actual diet plan itself! Obviously, we don’t like to see people being ripped off, hence why we would not recommend any diet plan that we believe to be excessively priced.
    2. The likelihood that followers will lose weight – This is another one that seems obvious, but is very important. In order for a diet to make it into this top 10 list, we must believe that it’ll genuinely produce weight loss results for those that follow it.
    3. Sustainability – One very important factor to us is how sustainable a diet is, therefore we do not recommend diets that we feel are probably going to be impossible to stick to; if it’s too hard, you’re unlikely to see any real results from it.
