1. She Gained Weight Because of “Intolerances”

In 2019 she revealed to the Mail Online that she had rapidly gained weight and didn’t know why for a long time. "I've been diagnosed with all these intolerances over the past year and I'm just like, 'how am I going to cope?' because I've really noticed weight [has] just been going on so quickly. It never used to be like that for me, so that's like my personal struggle at the moment," she said.

“The last year I've been really listening to my body and I've just noticed how much I've been bloating, and really uncomfortable when I eat certain foods and I didn't really know what it was. I went to see a nutritionist and I got tested for everything and I have an intolerance to dairy, which is my main one and gluten and wheat,” she continued. "So basically I'm on an anti-inflammatory diet which is really, really hard when I used to eat whatever I wanted, so I've been struggling with that, I'm such a fussy eater as well, so it's hard.”

3. Stress Makes Her Lose Weight

During one of “the hardest times” of her life, Louisa dropped a lot of weight due to stress. “I was really low. I wasn't eating properly, I got really, really skinny,” she told Fabulous magazine.

4. She Exercises

Louisa has a moderate approach to exercise. “I go to yoga classes three times a week and I do a weekly gym session to stay toned,” she told Closer. "Research shows that a single set of 12 to 15 repetitions with the proper weight can build muscle efficiently in most people and can be as effective as three sets of the same exercise. As long as you take the muscle you are working to fatigue — meaning you can't lift another repetition — you are doing the work necessary to make the muscle stronger. And fatiguing at a higher number of repetitions means you likely are using a lighter weight, which will make it easier for you to control and maintain correct form," says the Mayo Clinic.

5. She Eats Healthy

Louisa eats healthy “most of the time,” she told Closer, “but then I indulge at the weekend. I try to be as healthy as I can and I buy organic products.” She also doesn’t eat red meat anymore and swaps out regular mayonnaise for vegan, “which is amazing,” she admits.

6. She Suggests Taking Baby Steps

Instead of making drastic changes, Louisa suggests taking baby steps. “Make small changes. If you’re not the kind of person to stick with a diet, then don’t dive in headfirst. The tiniest things can lead to big changes,” she told Closer.
