The pineapple diet, which is also sometimes called the Metzger Pineapple Diet, is a hard eating plan to nail down because there are many imitations online that call themselves the same, but are unfounded plans. While this fad diet might seem really restrictive, there is no denying that there is a lot of interest around this particular weight loss plan.

While some versions may differ, every form of this eating plan in some way or another involves eating a lot of pineapple. Some say all pineapple and ice water for a few days in a row, others add in tuna every day. Many have a combination ” where there’s a day or two of nothing but pineapple and water, but tuna on the rest of the days to go with the pineapple.

The pineapple diet is definitely a fad diet and should be undergone carefully. That said, does this eating plan help people lose weight? For many people, the answer will be yes.

The pineapple & tuna version of this idea tends to especially be effective because tuna is a great lean meat high in Omega-3s, protein, and low in calories. This is a great balance to the pineapple, which delivers a great amount of energy for a fruit. This combination, along with ice water, can help to guarantee a diet low in both fat and salt. There are several concerns with this diet, however.

First, one of the largest concerns is sugar. Pineapple is a fruit that has a very high fructose (sugar) content. For diabetics who have to watch their insulin, this could become a major issue. Pineapple is also a very acidic fruit, which could make it unappealing for many different individuals.

A common second concern with the pineapple diet is lack of nutritional balance. While pineapple and tuna are both very healthy foods, you’re not going to get 100% of your daily vitamins from eating just that. A daily multi-vitamin is a very good idea.

Third, not all claims made about this weight loss plan have been proven. As with many fad diets, there’s the claim from diet proponents, and then many of them simply aren’t tested to be proved or disproved. This can be an issue for some people.

The pineapple diet might not be for everyone. But as far as fad diets go, this one actually does help dieters lose the weight they’re seeking to cut.
