Here, he says "Fat people, on average, are more selfish and self-indulgent than the general population", then proceeds to talk about gluttony being a sin.

Later on, he calls overweight and anorexic people disgusting and says they're gross.

What's disgusting is speaking like this about people's health issues.

The person he's watching then talks about how fat-shaming is not the way to go about this situation, and he actually thinks he's not fat-shaming, look how he reacts: https://youtu.be/FZsnYXXdKv8?t=930 (watch from 15:30 to 15:53)

???

His solution to this health issue is "just stop eating so much". He doesn't dedicate his life to science to fix it, no. Asmongold's best solution is "just stop eating". There, guys, it's solved.

He doesn't talk about how loose skin affects people's motivation to lose weight, how mental health might, etc.

As for how getting overweight happens, there's many reasons but it doesn't help how today's food affects our hunger and fullness hormones.

Next, eating disorders. If a person's feeling sad and food helps to lessen it, they're going to eat. People commit suicide from how sad they feel so, yeah, people will overeat. Knowing Asmongold, he'd go "Oh, here comes the emotional blackmail". Nah, bro. People who are suffering with depression, eating because it's the only thing helping besides meds, calling them disgusting and gross, it's unacceptable.

As for anorexia, there's people who do it to try and die. There's those who do it because of body dysmorphia.

Some people are also the way they are because things have happened to them and food is their coping mechanism.

The list goes on.

Just thought I'd make this post because it's pretty disgusting how he talks about health issues.

Edit:
Appalled at the replies making fun of Asmongold's appearance, teeth/hygiene, or house cleanliness. I hope one day people will be able to regrow a new set of teeth so they can be happier, and that includes Asmongold.

My advice:
I think before/after pictures/stories of people who have lost a lot of weight are a good source for motivation.

Our bodies burn the greatest amount of calories just from keeping our systems functioning. RMR (resting metabolic rate) is the amount of calories burned in a day without any extra activity. It's the calories burned when a person is sedentary, not active, and only performing basic activities of daily living (such as getting dressed, moving gently, and using the bathroom).

Carbohydrates make your body store energy as glucose reserves. You need to burn through this (don't eat carbohydrates) to switch your body over to burning fat for energy. You'll feel fatigued and tired until your body learns to efficiently burn fat again instead of carbs.

Put salt on your food, and keep hydrated with water.

If you can, have ibuprofen and paracetamol available for if you get headaches.
