If you’ve been into weight loss or fitness programs in any way recently, you’ve likely seen the keto diet online. This high-fat, low-carbohydrate diet is being marketed as a way to lose weight quickly. The results don’t last long, however, and it has even been linked to muscle loss if followed for too long.

Sirtfood Diet

The Sirtfood Diet is a 21-day diet that has an extreme calorie restriction and only eats foods rich in “sirtuins” such as parsley, blueberries, apples and green tea. Sirtuins are said to regulate inflammation, slow down the aging process and speed up the metabolism. However, in some parts of the diet you are limited to just 1000 calories, which is not only difficult to maintain but also dangerous to the body.


Optavia is a program of eating half lean protein and vegetables and half “fuel” or pre-made, processed meal replacement products made by the company that include bars, cereals, shakes and soup. Similar to the sirtfood diet, Optavia relies on extreme calorie restriction, so it is not sustainable in the long term.


Intermittent fasting

Intermittent fasting is a system in which meals are arranged around extended periods of voluntary fasting. Although there are many methods, a more popular option is daily timed fasting, which compresses a person’s non-fasting time into a 24-hour period. While the restrictive nature leads to weight loss, the extreme hunger and cravings that accompany not eating for long periods of time can force you to pause dieting before making any progress.

Whole 30

Described as a “nutritional reset”, Whole30 promises to detoxify your body while addressing food cravings, blood sugar management and inflammation problems at the same time. However, it requires extreme and sudden restraint over an extended period of time that may be difficult enough to sustain to see results.

“Ultimately, all of these diets are rigid“ diets ”that omit food groups or certain foods and thereby prevent permanent weight loss.” Young says, “People who diet and wear this headset generally fail because they can’t wait to quit the diet. ”She says it is best to allow all foods in, but practice portion control, which will allow you to maintain healthy habits and develop positive attitudes.

“I like to approach weight loss from a positive angle. Enjoy foods you love and think about healthy foods to add to your diet. ”It also encourages healthy food sharing that is easier to manage than rigid rules and restrictions. “For example, instead of a bagel with cream cheese, try avocado toast on wholemeal toast. Also, instead of focusing on the scale, focus on the lifestyle. “
