Hi , please i need a comment and a question for the post bellow .

The effectiveness of dieting has been debated for years. There are several diets available including Atkins, Zone, Carbohydrate, Weight – Watchers, Jenny Craig, Dukan, Mediterranean, or 22 Day Vegan. Choose two (2) diets that were listed previously then explain four (4) effects each of your selected diets has on one’s energy and overall health including any hazardous effects.

• Atkins- Decreased energy. The diet does not provide a lot energy in the form of carbohydrate. In fact, if you are a typical American eater before you start the diet, you'll significantly decrease your intake of carbs. For many dieters, this causes fatigue.
• Discomfort. There are some Atkins dieters who have experienced constipation, halitosis, and sometimes, dehydration as a result of the dietary changes in the eating plan.
• The Atkins diet emphasizes foods high in protein; however, foods high in protein may also be high in fat. Too much fat increases “bad” LDL cholesterol. Additionally, the diet limits or restricts fruits and vegetables, depriving dieters of the fiber essential for digestion, which may lead to chronic bowel disease. Limiting consumption of many fruits and vegetables also deprives dieters of antioxidants that help prevent cardiovascular disease and cancer.
• Reduced fruit and grain intake.If you're a dieter who loves fruit, you might struggle on the Atkins plan. Eventually, you can add fruits and grains into your diet, but in the early stages of the diet, your intake is limited. 
• 22 Day Vegan- Vegans need to make a conscious effort to eat the right quantity and combinations of food to get the nutrients they need to stay healthy. Cutting out dairy may result in lower calcium intake, which may put you at risk for bone fractures. Turn to dark green vegetables like kale and broccoli, as well as calcium-fortified soy products and juices. Iodine is an essential nutrient found naturally in sea food and dairy that is important for proper thyroid function. Vegans can use a little salt with iodine on their food or when they cook.
• The body does not absorb iron from plants as well as it does with iron from animal products. Vegans should eat iron-rich plant foods paired with vitamin C to improve iron absorption. Vegan sources of zinc and magnesium include whole grains, soy products, nuts and legumes. You may need to take vitamin supplements or find specific vitamin fortified foods to make sure you are getting enough vitamin B-12 and vitamin D. Omega-3 fatty acids, which are a key component of good health, are found in eggs and fish, so look into taking supplements to receive the nutritional benefits.
• A radical change: Going vegan is a huge change and can sometimes be even more complicated if you are not allowed to eat certain ingredients such as soy. "Complete plant proteins are found in soy products, so if you're trying to moderate your intake of soy, you have to learn how to put together complementary foods to form complete vegetarian proteins," says Keller.
• Potential interference with existing medical conditions: If you have a condition such as osteoporosis or diabetes, it is critical to consult with your physician and a registered dietitian when starting and implementing a vegan eating plan, as a vegan diet may interfere with your condition
