“Eternal summer here in Hawaii!” Jameson, 45, captioned a photo of herself at the pool. “So excited to go back to the mainland for a week soon! Update on #keto… I’m back on track and I’m taking you on my journey!.”

On Friday, Jameson, who is a self-proclaimed “keto queen,” admitted to her Instagram followers that shegained 20 lbs.during her brief reprieve from the keto diet.

“The weight came back fast and furious,” she said. “I know a lot of people are quitting keto because it’s hard to maintain and after a year and a half I concur. Not sure if I’m going to go back full force or just calorie count.”

“What are your thoughts?” she asked her followers before sending one final message, “Love you guys!”

She thenlost around 80 lbs.,which she detailed on Instagram inbefore-and-after photos.

In July, Jameson admitted to “losing control and eating like a crazed banshee” and then going back on the diet.

“We all do it,” shewrote on Instagram, explaining that these lapses happen to everyone at some point. “There are no exceptions. All the health gurus and fitness badasses do it.”

The mother of three went on to say it’s alright to feel “discouraged, disappointed and downright pissed” with yourself, but it’s important to “channel that into positivity.”

While Jameson praises the rigid diet, many people have come out against it. In June, doctor of integrative medicine and bestselling author Andrew Weil told PEOPLE that the keto diet is atrend that could be dangerous.

“I think it’s a fad, I don’t think it will last and I don’t think it’s a healthy way to eat for a length of time,” Dr. Weil said at an event forTrue Food Kitchen, a restaurant chain he co-founded that bases its menu on hisanti-inflammatory diet.

“It represents a misunderstanding,” said Dr. Weil. “There aregood and bad carbs. There are a lot of carbs that people eat that are going to promote weight gain and reduce insulin sensitivity and you want to learn the differences in kinds of carbohydrates so you limit the [bad carbs] that you eat but you don’t eliminate them totally.”

“You’re eliminating carbohydrates — it’s not a good idea to cut out a whole macronutrient. I think there’s a risk of getting serious deficiencies,” he added.
