I started down the gym a week before Christmas. Cut alcohol first of jan and been dieting and upping protein. Been going gym 4 times a week. Started weight training and lifting weights. Was feeling good this morning. Weighed in and ive lost 3lbs. Im a couple of stones overweight.

Im really demoralised. All my mates have lost loads of weight on ghe jabs. Im just wondering if im doing the right thing now. Aibu?

I’ve lost three stone in the past year using a combination of calorie counting, increasing protein and fibre, and lifting weights.
on weeks when my weight doesn’t go down I know I have had body shape changes. I am so much better toned, no wobble anymore. I am stronger and fitter.
I could’ve lost more weight on jabs probably but I know I have done so much more than lose weight. It depends on what you want.

If you're several stone overweight, get the jab. Losing multiple stones of weight can take years of work and, whilst it's great, it can be made much more accessible using weight management tools like mounjaro.

I lost a fair bit of weight last year for my wedding going to the gym and running (running definitely shed the most of it) whilst a friend started the jabs. She lost a lot more weight than me which is obviously a lot more money and to be honest the money she spent I would bloody hope they would work!

However, the side effects for me was I felt so much better in myself, stronger, fitter and had so much more energy. She was being sick a lot of the time and stomach issues. Whenever it was time for her to have the jab she had to write off those upcoming days because it knocked her about.

For me the worry is you don’t know the long term effects of these jabs, god knows what internal issues they are causing to you, however, having a healthy diet and fitness you know will make an impact on your life for the better.

its normal to feel deflated but I would keep on at the gym, maybe take up running as I felt that really helped with my weight loss.

Does it have to be one or the other? Most people I know on WLI are regular gym users and combine the two.

Are you doing any cardio too or just weights? Strength training is great but needs to be in combination with hard cardio. Start the gym with a run on the treadmill as a warm up. Strength training doesn’t burn as many calories as running. Running is the best way, hands down, to lose weight and burn lots of calories.

Also someone who is two stone overweight does not need jabs. The weight will come off, you just need to be patient. It won’t fly off as quickly as someone who is five or more stone overweight.

You can do both. In fact using jabs without weight training is likely to leave your body in a pretty crappy state.

If financially you have to choose between them, choose the gym.

My initial thought is, does it have to be either/or?

But also, the focus has to be about your own body and health. It doesn't matter what weight your friends have lost. 3lb loss in a month is actually pretty optimum, and you'll be getting all the health benefits from the weights too. You are doing well.

3 lbs is great for a month. You'll be gaining muscle mass. Take measurements too.

This is true!

Exercise has loads of other health benefits too.

Skip breakfast. Intermittent fasting. I’m skinny and realised when reviewing a students paper (academic) that that’s the reason I’m not fat. What time to you go to the gym.
