It is changing my life (for the better) but like you, at first I wasn’t sure. I debated it for quite a few months and then I saw a friend I’d not seen in ages and she looked fab, having lost 3 stone (and maintaining). I’m now 2.5stone down and have about another 2 stone to go. Even though I’m only halfway, all my shame and desire to hide away under baggy clothes has gone. I run up and down the stairs, I don’t huff and puff and desperately try to hang on to a firm surface if I need to get off the floor AND I’ve started really enjoying clothes shopping again.
As others have said, you do need to alter your food intake and how you think though.
On the few occasions I’ve strayed and eaten too much greasy food, oh my, I’ve paid for it with nausea and burps. But my day to day diet now is quite good. I have three medium-sized meals a day, built around protein so typically something like eggs with mushrooms for breakfast, tuna salad sandwich on Wholemeal for lunch and then dinner is a portion of whatever I fancy (could be roast chicken, fish, meatballs with sauce etc) but with veg on the side.
I can’t eat that much and on a normal day, eat around 1000 - 1100 cals. I’m short though so my TDEE is low. I’m very rarely hungry and I just don’t think about food. If I do, I drink lots of water with no sugar cordial (or lemon juice) and it soon passes. I also take collagen supplements and laxido most days for constipation.
At the beginning (4 months ago), I had horrible heart burn so I never left the house without Rennies but that’s settled down now.
Everyone is different but I think if you view it as a weight loss tool rather than some kind of magic solution and also, commit to changing how you eat and how you think about food, you could do really well.
If it were me, I’d honestly tell my partner. I think in general, if your relationship is good, life is better if you don’t have secrets from your partner. He might be against them because he’s read a lot of nonsense online (there is a lot of stupid stuff out there) but if you read the science of how they work, it actually makes a lot of sense.
While yes, ‘eat less, move more’ sounds really simple, the reality is, it’s NOT that simple and most of us have spent a big chunk of our adult life losing and re-gaining the same few stone for the simple reason that living in a calorie deficit constantly is a very tough way to live. There’s increasing amounts of research around GLP-1 and hunger hormones too, indicating that some people genetically find it much, much harder than others. Anyway, you’ve got nothing to lose from trying!
