Hard & Fast Diet Analyzed

Fact Checked


Perhaps one of the newer diets to be released, the Hard & Fast Diet has picked up quite a positive reputation for itself. With so many people reporting fantastic results, we’re looking in-depth into this program to give you all the information you’ll need to decide whether or not this diet is right for you.

Firstly, we really need to give it up for the author Michael Keane. This guy has taken the typical “eat less, move more” mold and thrown it out the window. The Hard & Fast Diet is unlikely to be like any other diet you’ve followed; it is more than likely going to be the hardest diet you’ll ever follow – luckily, if you’ve got the willpower and the backbone for it, you’ll more than likely be able to transform your body in a matter of weeks, not months or years.

There are hundreds of different diet guides available in book stores and on Amazon – all promising you quick and easy weight loss results; the Hard & Fast Diet is actually one of the only diet plans we’ve seen that is brutally honest about how difficult it is.

The author Michael Keane has reinvented the previously-negative label of “a crash diet” and transformed it into a highly effective, positive tactic for eradicating body fat in the shortest possible amount of time.

The diet is all about sacrificing short term pleasures for long term results. This is a diet for somebody who isn’t playing around anymore, for someone who demands visible weight loss within weeks, not years.

What Is The Hard & Fast Diet?

The Hard & Fast Diet is essentially a combination of three extremely useful weight loss methods. Michael Keane has taken the clinically-proven benefits of a carb-restricted VLCD (very low calorie diet) and combined it with a keto-inducing water fasting regime.

As we mentioned earlier, rather than being a diet that one would typically follow for years, the Hard & Fast Diet is essentially a total-body-reset diet that is designed to completely break your food addiction and push your body into fat burning mode in the shortest possible period of time.

So is the Hard & Fast Diet essentially just a crash diet? Absolutely, but as Michael Keane and the thousands of people worldwide seeing great results will tell you, crash diets aren’t a negative thing – in fact if used correctly, they can be a highly effective method of rapidly losing weight to get the body you desire.

Make no mistake, following the Hard & Fast Diet exactly as directed is going to be extremely difficult; you are going to need willpower and determination by the bucket-load. Luckily, Michael Keane has already realized this and has set up support mechanisms to help you stay on track.

Why The Hard & Fast Diet Is So Effective For Weight Loss

The main question most dieters have before starting a diet is, is this actually going to work? Based on our research, we genuinely believe that the Hard & Fast Diet will likely work for the majority of people who follow it.

The Hard & Fast Diet typically produces such substantial results is due to the following reasons:

  • The diet plan significantly lowers your daily caloric intake to the point where you’ll naturally start losing weight
  • The diet is designed to force your body to use its fat reserves as a primary source of energy
  • The diet helps reset the dieter’s relationships with food (i.e. it breaks food addictions)

The Benefits Of The Hard & Fast Diet

Other than obvious benefit of weight loss, there are a whole other host of health benefits to following the Hard & Fast Diet.

  • Helps you reach a health BMI level in the shortest possible amount of time
  • Can help shrink your stomach, which can help cause long term appetite suppression
  • It can help promote mental clarity and focus
  • Dieters have reported clearer skin

How Long Should I Be On The Hard & Fast Diet For?

Michael Keane states that users should only stick to the Hard & Fast Diet until they reach a healthy BMI range. Once this goal has been achieved, users are directed to stop the diet and move onto a weight maintenance diet.

Is The Hard & Fast Diet Safe?

There has been some controversy surrounding this diet in regards to it being unhealthy but that is simply not true.

Critics will say that the Hard & Fast Diet is nothing more than a starvation diet, however this is very misleading. The diet is simply designed to force your body to tap into your fat reserves for energy. In a literal sense, “starving” is when your body has ran out of things to use for energy and starts slowly attacking the organs, gradually leading to death. If you are classed as overweight, obese or morbidly obese, it’s going to be impossible for you to “starve to death” until all that excess body fat has been burned for energy and you’re skeletal-looking in nature.

The truth is the Hard & Fast Diet is completely safe if followed correctly.

The diet includes a full nutrition plan that ensures everyone who follows it gets all daily vitamins, minerals and essential nutrients – just because the diet has you regularly water fasting doesn’t mean that it is dangerous.

The fact of the matter is, being in an unhealthy BMI range is dangerous; the Hard & Fast Diet is one of the quickest ways to get yourself back into a healthy BMI range.

Hard & Fast Diet Side Effects?

We have compiled the following list of potential side effects for the Hard & Fast Diet, based on the directions:

  • Hunger
  • Increase in urination
  • Headaches
  • Feeling cold
  • Low energy levels
  • Dehydration
  • Lowered sex drive
  • “Impacted social life”

Note: these side effects are possible but may not be the typical user experience.

Based on what we’ve seen, we believe that the main side effects that will bother people the most will be nagging hunger cravings and lowered energy levels. While the hunger cravings will typically subside after 3 or 4 days of being on the diet, the initial transition may be somewhat difficult for people who are new to fasting-style diets.

If you feel your willpower waining, we’d recommend you pick up some effective appetite suppressant pills to tide you over until the hunger pangs stop.

As with most extreme calorie-restriction programs, you’re not really going to be as peppy and full-of-energy as you normally would be. Luckily, caffeine, green tea and vitamin B12 are your friends – supplementing these into your diet will improve the way you feel if you do happen to suffer from “diet-fatigue”.

Finally, while it may not be a side effect, we believe that most followers of the Hard & Fast Diet will, at some point, feel that their social life is impacted. In order to properly see weight loss results with diet plan, you’ll need to follow the directions down to a tee.

Essentially what we’re saying is you’re going to have to make sacrifices in your social life. You’ll need to accept that you’re going to be that guy with an ice-water at the bar, or the person who skips the popcorn at the movie theater.


Overall, we believe that the Hard & Fast Diet will be highly effective for those who are motivated enough to stick to it. When it all boils down, you’ve essentially just got a VLCD / water-fast diet plan that’s designed to induce ketosis. While it may be effective, as we stated earlier, this isn’t for the faint of heart (hence the name “Hard & Fast”).
