I think I might have to gain back some of my weight..

I think you should throw the scale away...preferably at the heads of the people who keep telling you that you are too skinny.

What idiocy is that? You look great.

If you want to put on some mass (rather than fat) eat about 250 calories or so above TDEE and follow a good resistance training programme for a sufficient period of time. If you find that you have put on a little too much fat with the overall increase in weight then you can always diet back down but do it slowly.

Only you can decide what is right for you. Go by how your clothes fit and how you feel and try not to get caught up in what other people are saying. They may just be concerned that you are going to lose more weight.

If you decide to regain a little weight, as others have said building a bit of muscle would be the best way to go. Strength train and eat at a small calorie surplus (100 to 200 cals over TDEE) to ensure you don't just put on fat but also build LBM.

You will also find that when you increase your calories you will feel much stronger when you are lifting. Muscles love to be well fed.

I think you look fantastic. Don't let others skew your image of yourself. IF you truly do want to gain, I would increase strength training. Good Luck to you :flowerforyou:

This^^ You look great!! My question is how do you feel? If you feel strong and healthy then to heck with other people calling you skinny. That could be their jealousy and own insecurity talking.
