How Much Weight Has Bert Kreischer Lost?

In various interviews and podcast appearances, Bert has stated that he lost around 50 pounds in about 5 months.

Considering his 6'3" frame, this amount of weight loss is dramatic and has led to a major slim down of his appearance.

Based on before and after photos, it's estimated Bert weighed over 250 pounds at his heaviest. He now looks to be under 200 pounds, which is a huge accomplishment.

Losing 50 pounds in 5 months equates to an average rate of 2-3 pounds per week, which is a safe and recommended pace for substantial weight loss.

What Is Bert Kreischer's Weight Loss Secret?

Bert credits several key factors that enabled him to lose weight quickly and effectively:

Intermittent Fasting

One of Bert's go-to weight loss strategies is intermittent fasting, which involves restricting food intake to set times during the day.

Popular intermittent fasting schedules include 16:8 (fasting for 16 hours, eating within 8 hours) or 20:4 (fasting for 20 hours, eating within 4 hours).

Bert likely experimented with different intermittent fasting windows to find what worked best for his schedule and appetite control.

Keto Diet

In addition to intermittent fasting, Bert followed a ketogenic or keto diet focused on very low carb, high fat and moderate protein.

Keto diets aim to get the body into ketosis, where it burns fats rather than carbs for fuel. Bert cut out sugar, grains, legumes, fruits and starchy vegetables.

Instead, his keto diet consisted of foods like eggs, avocado, salmon, chicken, turkey, nuts and non-starchy veggies. This enabled fast fat loss while feeling satiated.

Cutting Out Alcohol

Another major change was cutting out alcohol which can pack on empty calories. As part of his lifestyle overhaul, Bert gave up drinking which helped accelerate his weight loss.

No More Junk Food

Bert also cut out junk food like pizza, burgers, fries, chips, candy and desserts. Avoiding calorie-dense processed foods made room for more nutritious whole foods.

By combining intermittent fasting, keto diet, no alcohol and no junk food, Bert was able to lose weight quickly and safely.

Is Bert Kreischer's Weight Loss Healthy?

While Bert achieved remarkable weight loss results, losing 50 pounds in 5 months equates to 2-3 pounds per week which is a very rapid pace of loss.

This speed of weight loss raises some potential health concerns:

Nutritional Deficiencies

Cutting calories and carbs so severely increases the risk of nutritional deficiencies over time. Focusing just on keto-friendly proteins and fats could lead to lack of fiber, phytonutrients, vitamins, and minerals.

Bert will need to be mindful of incorporating sufficient veggies, some fruit, nuts/seeds to maintain proper nutrition, especially with his active lifestyle.

Metabolic Changes

Losing weight rapidly can sometimes slow the metabolic rate as the body tries to conserve energy. Bert may need to adjust his calorie intake going forward to avoid unwanted metabolic slowdown.

Gallstones Risk

Studies show rapid weight loss increases gallstone formation risk significantly. Bert may want to consider getting an ultrasound to check for gallstones.

Loose Skin

Dropping 50 pounds quickly could potentially lead to loose sagging skin. Bert may consider various cosmetic procedures to tighten skin.

For long-term health, Bert should focus on losing weight at a more gradual sustainable pace moving forward while ensuring he gets optimal nutrition to support his high activity levels.

What Are the Risks of Bert Kreischer's Weight Loss?

In addition to the concerns above, Bert's rapid weight loss poses some other potential drawbacks:

Nutrient Deficiencies

Bert's keto diet cuts out many foods containing fiber, vitamins, minerals and antioxidants. Deficiencies could emerge over time leading to low energy, poor immunity, digestive issues, or hair loss.

Muscle Loss

Consuming inadequate protein combined with intense cardio could cause Bert to burn not just fat but also lean muscle mass. He'll need sufficient protein intake and strength training.

Weight Regain

Losing a lot of weight rapidly often leads to weight regain once normal eating resumes. Bert will need to develop a sustainable lifestyle plan.

Metabolic Adaptation

As mentioned, overly rapid weight loss can cause adaptive thermogenesis, where the body adapts by reducing calories burned at rest, making weight loss harder over time.

Eating Disorder Tendencies

Developing obsessive behaviors around food restriction increases eating disorder risks like binge eating or bulimia. Bert should practice moderation and balance.

To maintain his results and stay healthy, Bert will need to ensure he fuels his body properly and keeps up healthy habits long-term.
