What is it?

The Oatmeal Diet is a weight loss diet that suggests eating large amounts of oatmeal to help control appetite. This is made possible by oats low calorie content and high fiber.

The claim made is that by using this diet you’ll be able to improve your health and lose weight safely and gradually. There are 3 separate phases and it’s advised to only use this diet for the recommended periods. Information on the Oatmeal Diet is limited since there’s no official website, but there are multiple sites which describe the diet. In reviewing many kinds of weight loss diets our review experts have found the 18Shake Diet to be the most effective. This is because it combines a meal replacement for hours of appetite suppression, and a fat burning diet pill to maximize results. Learn more about the 18Shake Diet by clicking this link.

Oatmeal Diet Ingredients and Side Effects

The main thing you’ll be eating is oats which are high in fiber for appetite suppression, and they can help reduce bad cholesterol. There are 3 distinct phases one must follow which includes:

  • Phase One: Only whole oatmeal (not instant) is allowed for the entire first week period. After these 7 days are finished you’re allowed granola bars and instant oatmeal.

It’s recommended to eat ½ cup of oatmeal at each meal, and if one wants a ½ cup of skim milk. The amount of calories you eat should amount to around 900 to 1,200.

  • Phase Two: For the following 30 days you have to eat a ½ cup of oatmeal three times daily as well as maintain a regular diet (no description is offered as to what to eat). As a morning snack a ½ cup of fruit is allowed, and for a lunch snack you can eat ½ cup of uncooked vegetables.

       Your calorie limit should be 1,000 to 1,300 a day.

  • Phase Three: After another 30 days you can eat a regular diet but must introduce a snack and a daily meal of oatmeal. Fats are also limited but there’s no explanation as to by how much.

The issue with this diet is that it demands an extreme caloric limit. You’re only allowed oatmeal for a full 7 days which can result in side effects such as:

  • Nausea, loss of energy, and lack of vitamin and minerals.
  • Headaches, increased bathroom usage, and indigestion.

Receiving only 900 to 1,200 calories a day for the first week can result in side effects and would be too extreme to follow for most. Health.gov recommends:

“Estimates range from 1,600 to 2,400 calories per day for adult women and 2,000 to 3,000 calories per day for adult men”

The Oatmeal Diet’s allows for a maximum of 1,200 calories. This amounts to the following:

  • 1,200 (maximum of Oatmeal Diet) – 1,600 (minimum an adult woman needs) = -400 caloric reduction.
  • 1,200 (maximum of Oatmeal Diet) – 2,000 (minimum an adult man needs) = -800 caloric reduction.

Nutritionists often advise a 200 to 500 calorie cut maximum, but this is often with an advised diet of nutritious foods, not just oatmeal. This is to provide the body with the fuel it needs from an assortment of important nutrients. The body cannot function properly without these essential vitamins and minerals.

Oatmeal is lacking in vitamins and minerals and per cup offers the following:

  • 0% Vitamin D.
  • 0% Vitamin C.
  • 0% B Vitamins.
  • 0% Vitamin K.
  • 15% Magnesium.
  • 18% Calcium.

Vitamins C, D, B, and K are not available and to go without these important vitamins can cause nutritional deficiencies.

There’s also no support from this diet to help explain exactly what kind of foods one should eat after the first phase is completed. You’re told to eat a small serving of fruits and vegetables, but this is a snack and not a full meal. It’s unknown what kind of foods one should be eating after the first phase is over.

Oatmeal is a healthy meal to have, but to use it as a main source of nutrition isn’t varied enough to sustain the body. Discover which weight loss diets were rated as the best overall by clicking this link.

Oatmeal Diet Quality of Ingredients

This diet is poor in quality due to 3 main issues.

  • The calorie limit can be extremely difficult.
  • Eating either only oatmeal or mainly oatmeal can lead to nutritional deficiencies.
  • You’re told to uphold a regular diet while introducing oatmeal regularly, but they don’t offer a specific diet to follow.

No actual science is given to help support the claim that this is a healthy and safe way to lose weight. The diet is far too rigid and recommends one to significantly reduce their calories without recognizing the fact that people have different demands.

It’s not a one size fits all diet and relies on a calorie limit which would be far too extreme for most to follow safely.

The Price and Quality of Oatmeal Diet

Paying for oatmeal is often cheap and it is a year round food found in most markets. While oatmeal does not cost much, the fact that this will be the bulk of your diet can be difficult to sustain.

For the first week they also advise only a bit of skim milk without any toppings. This can be extremely hard to maintain as it can become boring and unsatisfying. Your options for flavorings are low and you’re not getting sufficient fat and protein.

Without any legitimate science offered its unknown whether or not this has been proven to be a real solution for weight loss. Any limit on calories that is this extreme will likely result in weight loss no matter what food is chosen. Learn about which diets were featured in the best of list found here.

Business of Oatmeal Diet

It’s unknown who created this diet and there is no official website. All the information about the Oatmeal Diet is only available on unofficial websites.

There is no official guide or book offered either, and if you have any questions about this diet there’s no one to ask. The phases are described in short without much emphasis on if there are any substitutions or tips.

One website does say you can lose 20 pounds on this diet, but none of the other sites makes this claim. Without an official resource it’s impossible to decide whether or not this diet is backed by any science.

Customer Opinions of Oatmeal Diet

Here are some select customer reviews found online:

“it’s super strict following this diet and you really have to make it work”

“it’s unlikely you’ll get all the nutrients your body needs”

“it’s far too boring and I have no idea why anyone would ever try this diet”

“nothing special is in oats to help you lose weight any quicker. This is just another way of reducing your calories.”

People often mentioned how they felt this was just another fad diet, and that it was not sustainable for long term use.

Some who have tried this diet said that it’s extremely difficult and that not only is it boring, but it does not help to suppress appetite. Users were often left wanting more food due to the significant caloric reduction needed.

Overall the main impression of the Oatmeal Diet is that it’s simply another version of a reduce calorie diet. There’s nothing unique in the food selections offered which can help with weight loss other than the increased intake of fiber. People often said they quickly became bored of eating just oatmeal and they would not recommend it. For a list of the best weight loss diets, click on this link.
