I find it quite poetic that modern man needs to go live by a lake, foraging naked for a few months to regain our reproductive viability.
This is why anabolic steroid users can develop shrunken (atrophied) testicles.
In addition, through enzymatic equilibrium, you will also produce more estrogen (excess testosterone is converted to estrogen and vice versa), which will further decrease male reproductive ability, and in sufficient quantities will stimulate breast gland growth.
In short, administering exogenous testosterone will have counterproductive reproductive consequences.
Nonsense. Overeating makes you fat, not a specific carb. Having a biscuit with a few grams of sugar is not going to impact your health in a meaningful way if you're not overeating.
The difficulty of dieting (and life in general!) is decisions. By being so absolutist it made it easier to just do it automatically rather than constantly weight up whether I should eat well.
That’s in hindsight.
At the time in my mind I was really convinced that that one biscuit might make the difference.
Eating sugar creates a cascade of hormonal knock-on effects that can make you fat.
I beg of you (especially if you're struggling with your weight!) to consider the alternatives to Calories-In/Calories-Out eating.
My dad is a doctor, he's _convinced_ it's all CICO (which is what was taught to physicians in the 70s, and today), he struggles with his weight, constantly, and is super unhealthy. He eats low-fat everything, and is in miserable physical shape.
He's blind to alternatives. It is unbecoming of a man of science to be so tied to a possibly-incorrect view of such an important topic.

If you find avoiding sugar helps you maintain a healthy diet than great, go for it. Do whatever works for you. But if your overall diet is a healthy balance then having a biscuit with tea is not going to negatively impact your health.
It's like saying an alcoholic can still responsibly drink by stopping at one.
While you do caveat things in your second comment, both your original and second comment basically minimize the OPs "not even one" stance, even calling it "nonsense". Replacing everything you say with alcohol shows the disconnect; you wouldn't say similar things to an alcoholic who said "alcohol makes you intoxicated", saying that's nonsense (since there are plenty of substances that can make you intoxicated) and then proceed to tell them that one drink is fine.
_However_ some calories keep you hungry so it's probably _much_ easier to limit your calories on low-sugar than a high-sugar diet.
For example, the carbohydrates in fiber are not digestable, so those calories have effectively no impact on weight. Starches take longer to digest than simple sugars, so they result in less of an insulin response than the same quantity of simple sugars (meaning, if eating in excess, less starch is converted to fat).
And even when just looking at simple sugars, fructose and glucose are processed by completely different metabolic pathways. The 5% difference in fructose content in HFCS (along with the double-digit difference in the % of "free" fructose) results in a significantly higher insulin response than plain old sugar.
Indeed, if one eats a lot of sugar, as a result of insulin response, it is possible to get fatter even though one is eating at a net deficit and losing weight.
Which is why fiber doesn't get counted towards calories on labels.
> Starches take longer to digest than simple sugars, so they result in less of an insulin response than the same quantity of simple sugars (meaning, if eating in excess, less starch is converted to fat).
That's not what it means. Insulin response cannot create fat out of nothing and doesn't result in more or less fat being stored.
If your glycogen stores are full and you consume more than you burn the excess calories are stored as fat regardless of the source or the pathway that stores it.
Calories in, calories out means you have to factor in how many calories from the food are available for your body to use. It doesn't necessarily mean the calories of the food you put in your mouth.
Or if you just want a simpler explanation - eating sugar makes you crave more sugar and so you’re a lot more likely to over eat.
That's it, no more donuts for me.
What the hell is an American biscuit then?
Basically, a chemically (as opposed to yeast) leavened bread roll.
As it had been for millennia before, I wager.
If you want to start a family and are struggling to do so, that is very difficult to reconcile.
But when you do, there’s a lot wrong with it.
