Is 30 push ups and 100 sit ups enough to lose weight

Hi I am wanting to lose a few stone but it isn't coming off and I don't know why. I have been doing push ups and sit ups but it isn't working. Advice please?

No.

In order to lose weight it is pretty simple - don't eat for 3 weeks and I guarantee you will drop to whatever weight you wish you were.

Joking. Don't do that - it will make your fat loss even more difficult.

Make sure you focus on your diet. Very simple rules, especially for regular normal people like you and me who aren't going for 1% bodyfat bodybuilding madness.

Caloric Deficit, Macronutrient balance, Resistance training.

Caloric deficit - easy enough. Cut the crap out of your diet (crisps, soft drink, chocolate, sweets) because they are nothing more than junk calories. A buttload of simple sugar that gives you nothing but a rush for a couple minutes. Start tracking your calories by looking at what you eat. Give it a shot for a couple of weeks and you will see just how much calories you can cut over a month by not eating that extra bag of walkers each day.

Macronutrients - what are they? Carbs, Protein, Fat. Easy fix - high protein, low carbs, regulated fat.
Chicken breasts, lean beef/pork (make sure it is lean, check the labels when you buy them for fat % content), fish - eat these. These should be the staple of your meal. Start off simple with just having a little more of these than you do usually, and when you start seeing results you can get a bit more advanced with juggling portion size based off your daily protein intake.
Carbs - there are some controversy over carbs. Some ppl think they are terrible, some take it as the holy grail of human dietary. Don't over complicate it. Eat your carbs, just less than usual, because these are your primary income of energy. Make sure you go with complex carbs - eg: rice, wholemeal bread, corn etc. Though carbs are the main element you need to control for fat loss, don't cut these too low. Lower your carb intake little by little, ease your body into a low carb diet.

You both typed too much for me to be bothered to read it lol. I only eat fatty foods on the weekend and things like chocolate and cake but in the week I have cut down what i eat and i am not losing i don't understand.

should i upgrade to 200 sit ups then to burn calories?i am willing to put in the hard work

EDIT. I also plank 3 times a day so i am already working hard to lose it.

Doing what you’re doing won’t make much difference, cut out healthy snacks and exercise properly more, go for walks. It’s not gonna fall off you but let it be a slow process, it’s a lifestyle change not a quick fix

I only eat things like pizza and chocolate two days a week and i diet for the rest

That’s great, don’t cut out sugary foods completely or else you might binge. If you’ve changed your diet then now you just need to become more active. Those together will be great. Don’t make this about looking good, make this about improving you fitness and health xx

diet comes before exercise when losing weight.
I'll put it short and simple, sugar-free drinks (water is best)
Switch ice-cream to ice-lollies.
Crisps -> baked alternative.
eat 3 meals a day, with little snacking in between.
Forget about 100 sit ups, not cardio.

I will try water instead, I don't eat ice cream, I only have a bag of crisps a day, I do eat 3 meals a day and should I do 200 sit ups then?

no - stop doing sit ups and stop eating crisps.

Well what should I do instead then? I need to work out to lose weight obviously. & a bag of crisps only has 200 calories in it.

Wanting to lose weight but won't read what people have said even though they took time out of their day to make your life better?????

They put like a thousand words in their reply and didn't bother to paragraph it so it was hard to read
