If your husband has no fitness foundation and just started to learn, it is wrong to skip dinner. Skipping dinner will reduce basal metabolism, cause muscle loss and form a "fat constitution". You buy him some energy+bars, especially low-calorie food designed for fitness. Novices are particularly prone to exhaustion in the general fitness process. Pay attention to energetic red raisins, cashews, almonds, etc. In the machine, dietary fiber and high-quality energy can be supplemented to relieve fatigue quickly. Moreover, in the small package of 25g, the small package will make you feel full, and eating it will not make you feel guilty about your husband. Anyway, I have been eating it myself, so I recommend it to you.
