1. The Wheat Belly Diet. If you love the foods that Wheat Belly plan eliminates from your diet, you're better off limiting the intake of those foods rather than removing them from your diet altogether. A more reasonable approach is often safer than a risky 'all or nothing' tactic. You could easily gain weight if you fall off the wagon and overindulge.

2. Paleo Diet. This diet, also called the caveman diet, is popular among heavy exercisers. Dieters on it eat grass-fed meats, seafood, healthy oils, fresh produce, eggs, nuts and seeds while avoiding a wide range of foods including anything processed, dairy products, cereal grains, potatoes and salt. While the foods allowed on the diet are decent healthy foods, some dieters who are constantly on the go may struggle to maintain this fairly restrictive plan.

3. Military Diet. This 3-day diet claims to help dieters lose weight quickly. It advertises that if you follow the program you can lose 10 pounds in the first week and 30 pounds in the first month. But you'll be eating primarily saltines, tuna, hot dogs and grapefruit. On your four "off" days you need to restrict your intake to 1200 - 1500 calories of lean protein, fruits and veggies. The plan is simply not reasonable for most people for the long term.

4. Gluten-free Diet. Going cold turkey on cereal, bread products, crackers and other gluten containing products may not be realistic for people who have made those foods a regular part of their everyday diets. Of course, many companies are now making gluten free varieties of popular snacks and treats. But many of them are full of sugar, starch and calories - not necessarily healthy replacements for gluten.

5. Juicing/Smoothies/Liquid Diets. It sounds simple and appealing to many dieters. But even though these weight loss plans are simple, there are significant downsides to juicing and so-called "healthy" smoothies aren't good for your diet in some situations. If you are a person who really enjoys food - cooking it, tasting it and eating it, then liquid diets may not be the best solution for you.

6. Packaged Food Diets. Programs that offer packaged foods are popular among people who need a convenient eating program. But some of the meals on these programs are high in sodium - making them poor choices for dieters with high blood pressure. Portion sizes also tend to be very small. If you like to eat a lot of food or if you have special health concerns you might want to chat with a registered dietitian before investing in one of these plans.
