Child's gained weight with daily exercising

117 replies

Artie30 · 23/10/2021 09:46

Hello all. It seems a child's weight post can get pretty nasty but want some advice... I'll take the bit.

Ds is 10, he has asd. He's about 145cm tall. A few weeks ago he was 6.5 Stone which put him in the overweight category.

He doesn't really care about his weight so it goes over his head, which is good. I don't want him obsessing over his weight.

I've been trying to watch what he eats. Also we've bought him a new bike since his old one got too small. For the last 3-4 weeks he's been out on it daily. For an hour outside after school each day and often going on 2 mile bike rides with Dp... he's obsessed with his new bike.

I felt like he was looking like he'd slimmed down a bit, in the face too I think!

But I've weighed him today and he is 6 Stone 12.5! Nearly 7 Stone. Wtf?? Surely he can't gain half a stone in a few weeks whilst we are making an effort with his diet and exercise.

He is 10 nearly 11! He is in 11-12 clothes that fit him fine so not in clothes big for his age!

What the hell do I do now?

His diet isn't the best but not the worst either. He only drinks water, hates anything sweet, he's partial to chocolate and crisps but in moderation. He doesn't like sweets.

For breakfast it's usually 2 slices of marmite on toast, school lunches on week days and usually fish fingers for dinner (he will only eat fish fingers atm, don't hate me). He maybe had a packet of crisps in the evening but that's it. Weekends he may eat a little more but not extreme!

Are you sure he's not sneaking food or eating secretly? From what you said it does not sound like he's eating loads. Both my DC eat way more than that and aren't overweight

BFrazzled · 23/10/2021 11:19

OP, does he look chubby? This is really the only measure you should use.

I would never weight my children, it depends so much on body composition, before/after growth spurt, etc. My kids are very muscular, and they are heavier than their peers (dd probably by several kilos ) but in fact she barely has any fat on her body. Muscles weight more than fat, and these ranges for kids (or adults) are really meaningless....

Nix32 · 23/10/2021 11:19

I would forget about weighing him completely and focus on body shape. Does he look overweight or in proportion? Assess from there and then adjust his diet.

My 13 year old has always been solid - broad shoulders, thighs that are pure muscle - but he's very sporty and active. I am sure if I weighed him he would be overweight, but he doesn't look it.

@chesterelly

Well on the chart I checked he was bang in the middle of the healthy weight band. You think his face is leaner. He is probably burning fat but building muscle. Obviously a lb of fat weighs the same as a lb of muscle but the muscle will be leaner. Stop obsessing or you are going to give him a problem. You said he didn't care about his weight. Good! Because he has nothing to care about.
Agree with this. OP, weight isn't the only indicator of physical health. Don't fixate on it. If he's getting plenty exercise and his diet is fine, he looks well - even a bit leaner than before - then all is well. Be pleased. It sounds like you have a happy and healthy boy.
Strugglingtodomybest · 23/10/2021 11:34

I have never weighed my children, I'm quite surprised/shocked that people do. OP I think your son sounds like he's doing fine. Both my sons looked chubby at that age, they need that extra flesh for the growth spurt to come.

dangermouseisace · 23/10/2021 11:35

I really wouldn’t worry. He’ll have a massive growth spurt soon. It sounds like he has a healthy lifestyle!

Hont1986 · 23/10/2021 12:04

Exercise has a surprisingly small effect on weight loss. If you want him to lose weight, reducing his portions will be the biggest factor. But that said, I'd just wait for his growth spurt to take care of it.

Daftasabroom · 23/10/2021 12:12

@Artie30 our ASD DS1 had a very limited range of foods but now makes himself a nutribullet smoothy every morning, lots of frozen fruit, bananas, oat (or rice, coconut, almond) milk, spinach, coco, etc. Might be worth a try.

horseymum · 23/10/2021 12:32

Sounds like he's doing really well, maybe start to increase the length and intensity of the bike rides if he enjoys it as 2 miles probably uses less energy than walking for much further. Have you got a pump track or skills trail nearby to build up skills, then find some mountain biking trails to try. Going up hills will really build cardio capacity. I find a short slow pedal doesn't use much energy at all, it's hills that really help but keep it fun. The increased exercise will fuel his appetite too and lots of kids eat more things when hungry.

Thank you. Not within walking (cycling) distance. Need to try and get a bike rack for car to go elsewhere. we are quite rural though so there's loads of hills here, woodland walks, country lanes etc!

Thank you. To be honest I don't make a point of weighing mine all that often! It's not a regular thing really! He hasn't grown much in height for a while so hoping he'll shoot up soon. Not sure what the average height is for his age but most of the boys un his class lot taller than him - not sure if he's short or they are really tall though!

I don't think anyone would look at him and think he's very overweight. He's always been pretty solid and broad... even when he was small!

I don't think so as he's never unsupervised. I literally need eyes everywhere with him and he won't be downstairs alone when I'm upstairs and vice versa! He doesn't go out to the shops alone or anything either like many children in his class do after school - his asd means he cannot really go out and play alone!

Maybe slightly more heavier than some of his friends - some of which are very skinny but certainly not a huge difference. He's quite solid... a lot of kids in his class are smaller and a lot bigger (had a class photo recently). He doesn't stand out as being very large!

Also asking, as he's in year 6 and they will be weighing him soon! 😏 was thinking of opting out but think we'll stick with it!

My 5 ft 11 son weighs 7 st 12 :( which I am worried about. Your kid sounds fine. It seems curious that you're almost drawing a veil over those posters pointing out that he's not overweight according to any known measure.

Pedalpushers · 23/10/2021 13:12

I wish people would stop trotting out the 'building muscle' thing. A bodybuilder can't gain more than about a pound of muscle a month doing intense daily weightlifting, cardio on a bike does not build muscle.

It's probably normal fluctuations of water, hormonal changes, hunger changes, salty meal etc. Weight fluctuates!

Crystal90567 · 23/10/2021 13:31

The Rock weighs 20 stone.

Big muscle bound men weigh quite a lot. Its nothing like the usual weight scales youd think.

My son is 12yo old and 9stone but fit as a fiddle and a rugby player. I'll find a stock image of a catalogue model type kid like him.

Vieve1325 · 23/10/2021 13:38

Just coming here to correct one thing - muscle does not weigh more than fat. Muscle is DENSER than fat.

1lb of muscle and 1lb of fat weigh the same.

1cm2 of muscle will be heavier than 1cm2 of fat. That's how it works.

Crystal90567 · 23/10/2021 13:43

These men are 16 stone + and professional sportsmen at the top of their game.

My point is you cant weigh boys by the same scales/rules, as its different for men and mums of boys should be aware of that, esp age 10 -18.

I'm the first to admit that Ds'a diet is rubbish

Well, surely that's going to be the biggest health concern? A 2 mile bike ride isn't a big deal fitness-wise (I hear what you're saying re. hypermobility). There's no need for any of us to be eating crisps or chocolate every week.

What's the quality of his sleep like?

He has autism. It's not his or my fault. It's not a terrible diet, just very selective and unvaried. He doesn't eat chocolate and crisps all the time, I just said he likes them.

Quality of sleep is okay. Takes a while to go sleep but will sleep all night once asleep.

I put his weight into nhs bmi calculator and it said he is overweight so I went by that!

Crystal90567 · 23/10/2021 14:02

7st 12 is very underweight for a 5ft11 male, but its allowable as he's a child so yet to broaden out. I'd say 7st12 is still quite a low weight for anyone 5ft 11. Must be quite skinny.
Depends on age a bit but 5'11 I'd guess 15yo?
