6 Celeb diets to try now

Singer Adele dropped major weight back in 2020, leaving lots of fans wondering exactly how she did it. She posted on social media about turning to exercise to keep her mental health in check, but she also reportedly went on the Sirtfood Diet.

The Sirtfood Diet is actually a plan that involves less restriction than many other diets, because it primarily involves adding foods high in something called sirtuin activators—sirtuins being a specific type of protein that helps reduce inflammation, boost metabolism, and burn fat.

There are lots of tasty options to choose from in the Sirtfood Diet, including things like wine, chocolate, apple, berries, walnuts, and olive oil. But in order to lose weight on it, you do have to keep calories in check. Some recommend starting out by limiting your daily calorie intake to 1,000 calories per day the first week and 1,500 after that, while adding in Sirtfood-heavy green juices and meals each day. Eating as many Sirtfoods daily as possible without consuming too many or too few calories is the goal.

Jennifer Lopez is well-known for her discipline and dedication when it comes to health and fitness, but even she needs to shed a few pounds sometimes. She's been known to turn to intermittent fasting, a trendy diet that involves only eating between certain hours each day.

At its core, intermittent fasting is more of an eating pattern than a diet. There typically aren't restrictions on what types of foods an individual eats, just when they eat. It involves fasting for long stretches of each day or even fasting for entire days each week, but eating whatever you like when you're not fasting.

The most common methods of intermittent fasting are the 16/8 method, which involves not eating breakfast and limiting consumption to eight hours per day and then fasting for the next 16 hours; the Eat-Stop-Eat method, which means not eating for 24 hours straight once or twice per week; and the 5:2 method, which involves eating normally five days per week but limiting to 500 to 600 calories two days a week. There are other methods with varying increments of fasting and consuming hours, but these are the most popular. Black coffee, unsweetened tea, and water are typically allowed during fasting hours.

Kim Kardashian is the latest of many celebrities who have dabbled in plant-based or vegan dieting. She announced on Instagram early in January 2021 that she and her sisters would be going totally plant-based for 30 days and committing to working out twice a day during that time.

Going plant-based is incredibly straightforward. It means eliminating all animal products, including dairy. So no meat, cheese, milk, honey, etc. and loading up on veggies, fruit, legumes, and whole grains instead. Since most fruit and vegetables are far lower in calories than animal products, many people will lose weight initially after going plant-based.

It's important that if your goal is weight loss and you are replacing meat and dairy with calorie-dense grains and legumes, you may not lose any weight or may even gain weight if you're not mindful of portion size. Generally, though, nonstarchy veggies and many fruits can be consumed in unlimited quantities.

Cubana Eva Mendes has been known to use the 5-Factor Diet to lose weight when needed. The diet was designed by celebrity trainer Harley Pasternak and involves committing to eating five small meals per day for five weeks and doing five five-minute exercises each day.

With the 5-Factor Diet, individuals are allowed to eat foods from the five food groups along with sugar-free beverages. It focuses on lean protein, complex carbohydrates, fiber, and healthy fats.

This diet allows a wide variety of whole foods consumed in small portions at regular intervals, so you don't ever feel truly hungry. It includes things like fish, chicken, oats, fruit, and tons of veggies. Participants are instructed to focus on low-glycemic index/high-fiber foods to help regulate blood sugar and keep the metabolism working. One cheat day a week is also permitted.

Weight Watchers (aka WW) has long enlisted celebrity ambassadors to promote its weight loss and healthy lifestyle program, including Puerto Rican actress Adamari Lopez. The diet assigns a point value to different foods, and each individual's plan allows them a certain number of points each day.

Every person who participates in Weight Watchers takes a "personal assessment" that allows for an individualized weight loss plan. Each member will get a different number of daily points to use and should stop eating each day once they reach that number of points.

Weight Watchers provides a long list of "ZeroPoint" foods that can be consumed without counting toward a dieter's point total for the day. This list predominantly includes vegetables, fruit, legumes, and some lean proteins.

Actress and entrepreneur Jessica Alba is well known for her svelte physique, but she's still had to diet to improve her health. A few years ago, she turned to health coach Kelly LeVeque to help her get back on track with clean eating and get her blood sugar in check.

Kelly prescribed Jessica an anti-inflammatory diet plan she calls "Fab Four." It's designed to regulate blood sugar, increase energy, and reduce inflammation by ensuring that each meal includes protein, fat, fiber, and greens.

The Fab Four plan isn't terribly restrictive and doesn't specifically dictate what anyone should eat. Instead, it focuses on nutrients and eating regular meals throughout the day to avoid blood sugar drops and spikes that result in lots of snacking. Smoothies are a staple, but otherwise, it mostly focuses on meals composed of healthy whole foods like chicken, fish, nuts, green veggies, avocado, and lower-sugar fruits.
