It’s not uncommon for overweight patients to try to lose weight through diet and exercise several times. Diets vary widely. Generally, diet plans reduce caloric consumption or improve some bodily functions like fat digestion and protein absorption. The ketogenic diet has been the talk of the town recently.

Keto Diet: How It Works

Ketogenic diets aim to get patients into ketosis, a state in which fat is more easily burned.  A high protein and fat diet provide this strength.  Keto diets are typically high in fat or protein.  In a ketogenic diet (high-fat type), 75% of calories are fat, 20% are protein, and 5% of calories are carbohydrates.  Ketogenic diets are high in protein, fat, and carbs. About 60% fat, 35% protein, and 5% carbs make up a ketogenic diet.  In both types of the keto diet, carbohydrates and sugars are dramatically reduced.  According to several studies, there might be some heart benefits and weight loss.  However, once a healthier diet is resumed, there is usually very little long-term weight loss.

Additionally, high-fat diets increase cholesterol levels, triglycerides, and kidney stones.   The patient may also suffer from micronutrient deficiencies.  Therefore, doctors often don’t recommend this.

Keto Diets also Include:

  • Very-low-carb ketogenic diet (VLCKD) 
  • Well Formulated Ketogenic Diet (WFKD)
  • MCT Ketogenic Diet
  • Calorie-restricted ketogenic diet
  • Cyclical Ketogenic Diet (CKD)
  • Targeted Ketogenic Diet (TKD)

Keto diets change metabolism because of the high fat intake. Body parts “learn” how to efficiently process fat.   Once the diet returns to normal, however, this change does not persist.  Weight gain occurs once the patient begins eating more carbohydrates, fruits, and vegetables.

Bariatric Surgery Differs Fundamentally

With certain operations, the stomach is reduced in size, and nutrition may be absorbed differently.  Typically, a patient with a normal-size stomach eats about 1-2 quarts of food before surgery to feel full.  To feel full after surgery, a patient eats only about 1 cup per meal.

Before undergoing bariatric surgery, you must be prepared to make some major life changes. Our recommendation is:

  • Sugary drinks are to be eliminated
  • Eat three balanced meals each day
  • 3-4 hours of exercise per week
  • Stay in touch with us at Perth Surgical & Bariatrics to help you stay accountable and prevent weight regain

There is overwhelming medical evidence that bariatric surgery (when combined with lifestyle modifications) is superior to diet alone.  With surgery, patients typically lose more weight. In addition, the patient’s lifestyle can have a significant impact on the cure rate of type 2 diabetes, which ranges from 70-90% depending on their efforts.

You may benefit from bariatric surgery even if you need to lose 30 kilos. We aim to keep you from gaining more weight and to prevent you from becoming diabetic in the future.
