After giving birth, Katy Perry retired to take care of her family and young children, and no longer performed much. She also focuses on her personal business.

Because she rarely goes on stage to perform, Katy Perry also does not wear tight or too sexy outfits that were associated with her previous image.

Recently, the female singer caused a surprise when appearing on the iHeart Radio program with an extremely slim appearance, reminiscent of the peak period of her career.

The beauty went out of her way with a see-through mesh dress design that revealed the black lingerie worn underneath, showing off her seductive figure.

Katy Perry’s physique has changed markedly. Sharing about her weight loss process after giving birth, the female singer said she applied the Atkins diet (reduced starch intake) and worked out with a personal trainer to regain her shape.

Katy Perry started a low-carb, high-protein diet and continuously maintains this diet to maintain her weight.

The Atkins Diet is an extremely popular low-carbohydrate diet, developed in the 1960s by cardiologist Robert C. Atkins. This is a low-carb diet, pioneering the trend of cutting starch from daily meals.

The Atkins diet was born in the context of America facing a rising obesity epidemic due to people in this country being too fond of fast food, sugary soft drinks and fried potatoes.

Dr. Robert C. Atkins, after many years of research, has concluded that eating a lot of sugar and starch is the cause of obesity, cardiovascular diseases and diabetes. Cutting down on these foods will help lose weight effectively.

The new version of the Atkins diet used by Katy Perry is to increase green vegetables and limit starches such as rice, noodles, and bread.

However, the core of this diet remains unchanged: abstain from simple starches like rice and bread, and increase your intake of protein and fat.

Low-carb diets are effective for weight loss because reducing carbs and increasing protein leads to reduced appetite.

You can still lose weight while eating as much protein and fat as you want, as long as you avoid starchy foods.

Katy Perry’s meals during her weight loss phase always cut down on starch, she added lots of vegetables, fruits and protein from chicken, beef…

The Atkins diet is divided into 4 phases:

Phase 1 (starter): Under 20 grams of carbs per day for 2 weeks. Use foods high in fat and protein, with green leafy vegetables.
Phase 2 (balanced): Increase green vegetables, add nuts and fruits in your daily diet.

Phase 3 (fine-tuning): Once you’re close to your goal weight, add more carbs to your diet until weight loss slows.

Phase 4 (maintenance): You can eat healthy carbs as your body can tolerate without gaining weight.

Foods to avoid on the Atkins diet:

Sugar: Soft drinks, fruit juices, cakes, candy, ice cream…

Grains: Wheat, spelt, rye, barley, rice.

Seed oils: Soybean oil, corn oil, cottonseed oil, canola oil and others.

Foods to use on the Atkins diet

Meats: Beef, pork, lamb, chicken, bacon and other meats.

Fish and seafood contain lots of healthy fats: salmon, sardines…

Eggs: rich in omega-3 fats.

Low-carb vegetables: Kale, spinach, broccoli, asparagus and others.

Full-fat dairy: Butter, cheese, cream, full-fat yogurt.

Nuts: Almonds, macadamia nuts, walnuts, sunflower seeds…

Plant-based healthy fats: Extra virgin olive oil, avocado, and avocado oil

However, eliminating starchy foods also makes you hungry, causing some side effects such as headaches, dizziness, fatigue… Therefore, it is impossible to maintain a diet. On a long-term basis, you may even gain weight back after stopping the diet.

Katy Perry also only applies this diet for a short period of time, after which she will have a suitable menu to balance nutrition and maintain a slim figure.
