18 Pounds in 4 Days

 By Mizpah Matus B.Hlth.Sc(Hons)

18-pounds-in-4-days18 pounds in 4 days (18in4) is a weight loss program that was created by James Zeta.

In his search for the solution to his own weight loss concerns he states that he discovered a special combination of foods that enabled him to lose weight rapidly.

Zeta claims that his program can show dieters how to lose weight and even up to 18 pounds in 4 days. He says that he managed to lose 20 pounds in less than a week simply by following the principles outlined in his plan.

18 pounds in 4 days or 4.5 pounds a day is an unrealistic goal and most will set themselves up for disappointment!

18in4 Diet Basics

There are two parts to the program. The first part is the diet and the second part concentrates on maintaining the weight loss.

This diet aspect of the plan is a four-day calorie restricted diet, which is based around mainly vegetables with lean proteins and small amounts of fruits.

He advertises his program as not requiring any special foods, but rather as involving specific combinations of regular foods that supposedly jump starts the weight loss process.

Zeta asserts that there is no need for supplements, meal replacements, or exercise in order to achieve rapid weight loss.

He provides a detailed outline of what dieters should do for the first four days of his program along with a complete meal plan. He then offers tips to dieters that will help them to keep the weight loss in the long term.

Breakfast every day includes half a grapefruit and the rest of the diet is centered on vegetables with some eggs, chicken and meat.

Exercise Recommendations

Dieters are forbidden to exercise during the four-day program but exercise after is fine. He states that his clients actually achieve better results when they don’t exercise.

Costs and Expenses

The program costs $17 and payments are accepted via PayPal.


  • Includes a detailed 4-day meal plan.
  • Appeals to those who want to lose weight fast for a special event.
  • Rapid weight loss may increase motivation to stick with a longer-term approach to weight management.
  • Offers suggestions to help with maintaining weight loss.


In the comments below, many have complained about this diet by leaving negative feedback.

  • Most dieters will experience fatigue and hunger on such a low calorie diet.
  • Gives dieters unrealistic expectations in terms of weight loss.
  • Majority of weight loss will be water rather than fat.
  • Any weight lost is likely to be regained as soon as normal eating is resumed.
  • No scientific evidence is offered in order to support his claims.
  • Most of the support for the diet is in the form of testimonials.
  • Author of the diet has no nutrition or health credentials.
  • Expensive for a short program.
  • There are some reports of failure of the author to follow through with the money back guarantee.


Even if it were possible to lose 18 pounds in 4 days, it is certainly not a healthy approach to weight loss. If dieters experience any significant results on this program this will be largely attributed to water rather than true fat loss.

Zeta is encouraging a quick fix mentality that will ultimately leave dieters feeling discouraged when the desired results are not achieved. In addition his lack of credentials and the various reports of his failure to honor the money back guarantee brings his credibility and that of his diet into question.

Why not try 28 pounds in 28 days which is a healthier, more realistic option.
