Does collagen help with loose skin during weight loss?

The variables that decide loose skin, ranked, and the one that is not on the list

Does collagen help with loose skin during weight loss is a question with a word in the middle that changes everything, during, because the skin's response to weight loss is decided by a known list of variables while the loss is happening and in the year after, and the honest page ranks that list before looking for collagen on it. Variable one is the amount lost: skin stretched over fifty kilograms of fat for a decade has been remodelled to that size, its elastic fibres lengthened and in part broken, and it does not retract the way skin stretched over ten kilograms for a year does, so the amount is the largest single predictor of whether loose skin remains and the one a reader cannot change except by having lost less. Variable two is the speed: the rate of weight loss literature finds that slower loss, around half to one percent of body weight a week, with adequate protein and resistance training, preserves more lean mass than rapid loss, so that the volume under the skin falls as fat and not as muscle, and gives the skin's slow remodelling a chance to follow the shrinking volume rather than being left behind by it, the reason bariatric patients who lose fastest carry the most excess skin. Variable three is age, since dermal collagen and elastin decline across the decades and sharply after menopause, and a thirty-year-old's skin recoils from a loss that a sixty-year-old's cannot. Variables four and five are sun history and smoking, both of which degrade the elastic fibres skin needs to recoil, ultraviolet light by photoageing and smoking by impairing the whole of connective tissue repair, so a reader who has done both has skin with less spring before the loss begins. Variable six is genetics, the unchangeable difference between two people of the same age losing the same weight at the same speed and ending with different skin. Variable seven is time, since skin retraction continues for a year or more after weight stabilises, and a judgement made at three months is made too early. Collagen is not on the list, and the reason is not prejudice but the trials: the oral collagen skin trials were run in weight-stable people, mostly women aged thirty-five to sixty-five, and measured elasticity and hydration by instrument at 2.5 to 10 grams a day over eight to twelve weeks, a few percent in small, mostly industry-funded trials, and no trial has given collagen to people during a weight loss and measured skin laxity, retraction or excess, so collagen's evidence does not touch the question and the variables above are the whole of the answer.

The levers a lifter controls during a cut, what comes after, and the worked example inside a deficit

Of the seven variables, a lifter in the middle of a cut controls three and can influence a fourth, and those are the honest levers. The speed: set the deficit so that the loss runs at around half to one percent of body weight a week, half a kilo to a kilo for most lifters, which is slower than most cuts are run and is the rate at which lean mass is best preserved and the skin has the most time to follow. The volume beneath: keep resistance training through the cut, heavy enough to hold or build muscle, because skin follows what it covers and muscle filling the space the fat leaves is the only tightening a lifter can do from the inside, over the months of the cut and the year after. The protein: eat 1.6 to 2.2 grams per kilo from complete sources, the higher end in a deficit, since that is what preserves the muscle doing the filling and what the skin's own remodelling is built from, and a collagen scoop does not count toward it, lacking tryptophan and most of whey's leucine, so a reader who booked collagen as protein during a cut has under-eaten the protein that matters. The sun: daily sunscreen protects the elastic fibres the skin will need to recoil, a lever with a slow clock and the largest long-term effect on how skin looks. Then the variables a lifter cannot move: the amount is already decided, age and genetics are given, and smoking is a decision that has, in this case, one right answer. After the loss comes time, and the honest page is plain about how much: skin retraction continues for a year or more after weight stabilises, so the judgement of what is loose skin and what is skin still retracting is made at twelve to eighteen months and not at three, and where significant excess remains after that, an apron of skin at the abdomen, folds at the arms or thighs, it is a medical matter managed surgically, a conversation with a doctor about referral, and not a nutritional one, since no nutrient, collagen included, removes skin that has lost its elastic fibres. Collagen inside all this is stated on its true terms: a supplement whose skin trials do not touch the question, whose few percent by instrument in weight-stable people is not evidence about retraction, and which holds no skin or weight claim, so a reader who takes it during a cut takes it for the vitamin C line and the habit and books its calories, around five in a capsule dose and thirty-six in a dessertspoon, inside the deficit. The worked example is that supplement: two capsules, 1200mg hydrolysed type 1 marine collagen with 12mg vitamin C plus zinc, 120 for £16.99 at 28p a day, lab tested and UK made, around five calories, below the skin trial doses, taken for vitamin C's collagen formation sentence for skin and off the list of variables that decide the outcome. Does collagen help with loose skin during weight loss: the list that decides it is the amount, the speed, age, sun, smoking, genetics and time, collagen is not on it, and the levers a lifter holds are the rate, the barbell, the protein and the sunscreen.
