My question was whether fat burning can occur before glycogen stores got depleted? Any other reference that directly address it? The book Lore of Running is about running. I simply want to know if one walks for 2 hours a day and not run, whether fat burning can occur if the liver glycogen is...

This is a common questions in the mainstream. I just want to understand the exact chemical pathways. I read this for example: Someone asked: "Do you really need to "deplete glycogen stores" in order to burn fat at all?". Someone answered: "Let's get something clear. 95% of the people in ANY...

In exercise and workout for the purpose of losing weight. Isn't it that the glycogen in the liver takes 20 hours to deplete. Must one deplete glycogen storage first before fat burning in cells would be utilized? But I read conflicting reports that even without depleting glycogen storage, fats...

I found the source of the arguments. It's like this. When you run very fast upright and your foot hit a bump. What would happen. Is it not the bump impact would be transmitted to your foot and up to your body? Similarly, in balance bike where the kid foot is on the ground. If the foot hit a...

What do you think about Magnesium alloy frame? I heard it is fragile and can just break. I’m also thinking about stainless steel, aluminum or carbon steel body. But the latter quite heavy. And if 12” or 14” wheel size

Some 12" balance bike lists 80kg. some 30 kg.. that is why I need to know first if 12" pneumatic tire can take more than 30kg. If computations show it allows up to 80kg. Then I can believe some China data sheet which you know are not actually computed by mechanical analysis. They are not Honda...

The kid is 6 years old but overweight. He weights 75 lbs or 34 kg. Kid that age should only be 20 kg. What is the maximum weight that can be supported by typical air filled 12" pneumatic tires in a bike. I need computations so I can decide whether the tires can support him.

All of the wheels of the new balance bike I mentioned all use pneumatic air pump. Not solid rubber. I read somewhere that when a child is using pedal, the knees are bent and not touching the ground/road. Whereas when using balance bike without pedal, there is contact of feet with floor that can...

I used the following scooter with 5 inches wheel and suspension on the pavers weeks ago and I could feel the bumpiness. So you are saying the bigger wheel of the bike can average more of the surface and hence the bumpiness will be entirely gone? If not entirely gone, the suspension of the bike...

The reason I was looking for suspension for the 12" balance bike was because our enclosed or fenced apartment outdoor flooring uses Clay Brick Pavers like the following: There is no other place to use the 12" balance bike. We can't use it inside house as the area is small. And we can't use...

What is the difference if the wheel is 12" vs 14"? Does 14" wheel have suspension characteristic similar to the 12" with suspension? Also see the image below. The suspension is put differently. What would happen if the 12" balance bike in original message has this suspension configuration...

Please refer to this kiddie 12" wheel balance bike with suspension. Almost all kiddie balance bike (12" or 14" wheel diameter) don't have any suspension. Only a rare few has it, I found the above china made. I'd like to know the following. 1. In bicycle in general. Rear suspension is to...

Let me share the solution. I bought pure Titanium kettle. It solves the problems of plastic kettle releasing microplastics and stainless steel kettle releasing micrometals and plaguing you with hidden health problems later on.

I read stainless steel kettle can leech chromium and nickel, and these are not as dangerous as plastic kettle. I'm also looking for titanium kettle. I guess it is better than stainless steel kettle? I read one must look for "zero nickel migration" certificate when getting the stainless steel but...

Glass kettle is not option for me because I need the lightest. I bought the following and it was just delivered but found out it is not Stainless Steel 304 but ordinary stainless steel. I heard water can smell metallic with these (not 304). But can it release toxic compounds or only cause rusts...
